本发明涉及空气处理技术和地热资源技术领域，具体涉及一种利用地热温泉资源的溶液调湿空气处理系统及其处理方法。The invention relates to the fields of air treatment technology and geothermal resource technology, in particular to a solution humidity-adjusting air treatment system utilizing geothermal hot spring resources and a processing method thereof.
背景技术Background technique
对于大型商场、超市、会议室、礼堂、体育馆等大空间场所，通常采用集中式全空气系统。传统的全空气机组，一般是将室内回风与新风混合后，通过表冷器降温除湿以实现对室内的温湿度控制。For large-scale shopping malls, supermarkets, conference rooms, auditoriums, gymnasiums and other large spaces, a centralized full-air system is usually used. The traditional all-air unit generally mixes the indoor return air with the fresh air, and then cools and dehumidifies through the surface cooler to achieve indoor temperature and humidity control.
目前应用于空调领域的全空气机组一般采用冷凝除湿的方式，利用制冷机组制取低温冷水，将空气冷冻至露点以下，使空气中水蒸气冷凝成液态水，从而实现除湿。此种空气处理方式存在如下问题：由于空气处理机组负担了空气的湿负荷，因此通常用的都是温度较低的7摄氏度的冷冻水进行冷凝除湿，而冷冻水温度过低使得制冷机组蒸发温度也较低，从而导致制冷效率低下；同时，冷凝除湿后空气温度太低，有时需再热才能达到送风温度要求，造成冷热抵消、能源浪费；另一方面，表冷器的盘管存在凝结水，易滋生细菌。At present, the all-air unit used in the field of air conditioning generally adopts the method of condensation dehumidification. The refrigeration unit is used to produce low-temperature cold water, and the air is frozen below the dew point, so that the water vapor in the air is condensed into liquid water, thereby achieving dehumidification. This kind of air treatment method has the following problems: since the air handling unit bears the humidity load of the air, chilled water with a lower temperature of 7 degrees Celsius is usually used for condensation and dehumidification, and the temperature of the chilled water is too low to make the evaporation temperature of the refrigeration unit Also low, resulting in low cooling efficiency; at the same time, the air temperature after condensation and dehumidification is too low, and sometimes it needs to be reheated to meet the air supply temperature requirements, resulting in cold and heat offset and energy waste; on the other hand, the coil of the surface cooler has Condensed water is easy to breed bacteria.
溶液调湿空调系统近年来得到了较为广泛的关注。溶液调湿空调系统是指采用具有调湿功能的盐溶液作为介质，利用溶液除湿器对空气的湿度进行调节，并利用溶液再生器对调湿溶液进行再生，从而循环利用实现空气湿度调节的系统。调湿溶液通常采用溴化锂溶液或氯化锂溶液，安全、无毒，化学稳定性好。被处理空气的水蒸气分压力与吸湿溶液表面蒸汽压之间的压差是水分传递的驱动力。溶液调湿空调系统通常由溶液再生器、溶液除湿器、换热器和表冷器构成，其进行空气调节的过程如下：将湿度较高被处理空气通入溶液除湿器；在溶液除湿器中，通过喷淋低温高浓度的调湿溶液与湿度较高的空气进行接触，由于空气的蒸汽压大于高浓度调湿溶液的饱和蒸汽压，从而发生传热传质，空气中的水分传递给高浓度调湿溶液，而调湿溶液吸收空气中的水蒸气后，空气被除湿，同时一部分水蒸气的凝结潜热进入溶液，使得调湿溶液被稀释且温度略有升高，而被除湿的空气再经过通有制冷剂的表冷器进行制冷，达到预定的送风温度，而被送入室内；然后，被稀释的低浓度调湿溶液经过连接有热源的热交换器进行加热升温后，再进入溶液再生器；在溶液再生器中，通过绝热喷淋，高温的低浓度调湿溶液与外来空气接触，由于温度差与蒸汽压差的存在，发生了传热传质，低浓度调湿溶液中的热量与水分传递给了空气，从而再次转换为温度较低、浓度较高的调湿溶液，实现了调湿溶液的再生，再生后的调湿溶液再次被输送到除湿器，被循环利用于对空气除湿。由此循环，被降温、除湿的空气不断被送入室内，实现了对室内空气的温度、湿度调节。The solution humidity control air-conditioning system has been widely concerned in recent years. The solution humidity control air conditioning system refers to the use of salt solution with humidity control function as the medium, the use of solution dehumidifier to adjust the humidity of the air, and the use of solution regenerator to regenerate the humidity control solution, so as to realize the air humidity control system by recycling. Lithium bromide solution or lithium chloride solution is usually used as the humidity control solution, which is safe, non-toxic and has good chemical stability. The pressure difference between the water vapor partial pressure of the treated air and the surface vapor pressure of the hygroscopic solution is the driving force for moisture transfer. The solution humidity control air conditioning system is usually composed of a solution regenerator, a solution dehumidifier, a heat exchanger and a surface cooler. The air conditioning process is as follows: the air with high humidity is passed into the solution dehumidifier; in the solution dehumidifier , by spraying a low-temperature and high-concentration humidity-conditioning solution in contact with high-humidity air, since the vapor pressure of the air is greater than the saturated vapor pressure of the high-concentration humidity-conditioning solution, heat and mass transfer occurs, and the moisture in the air is transferred to the high humidity Concentration humidity control solution, and after the humidity control solution absorbs water vapor in the air, the air is dehumidified, and at the same time, a part of the latent heat of condensation of water vapor enters the solution, making the humidity control solution diluted and the temperature slightly increased, and the dehumidified air is again It is refrigerated by a surface cooler with a refrigerant to reach the predetermined air supply temperature, and then sent into the room; then, the diluted low-concentration humidity control solution is heated by a heat exchanger connected to a heat source, and then enters the room. Solution regenerator; in the solution regenerator, through adiabatic spraying, the high-temperature low-concentration humidity-conditioning solution contacts with the external air, due to the existence of temperature difference and vapor pressure difference, heat and mass transfer occurs, and the low-concentration humidity-conditioning solution The heat and moisture in the air are transferred to the air, which is converted into a humidity-conditioning solution with a lower temperature and a higher concentration, and the regeneration of the humidity-conditioning solution is realized. The regenerated humidity-conditioning solution is sent to the dehumidifier again and recycled for use in Dehumidifies the air. From this cycle, the cooled and dehumidified air is continuously sent into the room, realizing the temperature and humidity adjustment of the indoor air.
但现有的溶液调湿空调系统存在以下的一些不足。首先，现有的溶液调湿空调系统中通常采用电能加热作为热交换器的热源对被稀释的低浓度调湿溶液进行加热，用于实现调湿溶液再生，电能消耗大，不利于节能减排；另一方面，为了保证再生效率，通常需要将低浓度调湿溶液加热到较高温度后进入溶液再生器，这又导致再生后得到的高浓度调湿溶液温度也相对较高，使得利用再生得到的高浓度调湿溶液在溶液除湿器中对空气进行除湿处理的效率降低，同时对表冷器的制冷消耗也较大；此外，现有的溶液调湿空调系统通常只能实现对空气的降温、除湿，仅适宜于夏季使用，功能较为单一。However, the existing solution humidity control air-conditioning system has some disadvantages as follows. First of all, in the existing solution humidity control air conditioning system, electric energy heating is usually used as the heat source of the heat exchanger to heat the diluted low-concentration humidity control solution to realize the regeneration of the humidity control solution, which consumes a lot of electric energy and is not conducive to energy saving and emission reduction ; On the other hand, in order to ensure the regeneration efficiency, it is usually necessary to heat the low-concentration humidity-controlling solution to a higher temperature and then enter the solution regenerator, which in turn leads to a relatively high temperature of the high-concentration humidity-conditioning solution obtained after regeneration, making the use of regeneration The obtained high-concentration humidity-controlling solution has a lower efficiency in dehumidifying the air in the solution dehumidifier, and at the same time consumes a lot of cooling for the surface cooler; Cooling and dehumidification are only suitable for use in summer, and the functions are relatively single.

相比于现有技术，本发明具有以下有益效果：Compared with the prior art, the present invention has the following beneficial effects:
1、本发明的溶液调湿空气处理系统还直接利用了我国藏量较为丰富的地热温泉资源作为于实现调试溶液再生的热源，避免了使用电能等转换能源，不仅有助于减少能源的转换损耗、提高能源利用率，还有助于减少因能源转换滋生的污染排放，实现了节能减排。1. The solution humidity control air treatment system of the present invention also directly utilizes the relatively abundant geothermal hot spring resources in my country as the heat source for realizing the regeneration of the debugging solution, avoiding the use of electric energy and other conversion energy sources, which not only helps to reduce energy conversion losses , Improve energy utilization, and also help to reduce pollution emissions caused by energy conversion, and achieve energy saving and emission reduction.
2、本发明的溶液调湿空气处理系统通过结构优化，只需要进行简单的转换控制，就能够实现降温除湿、升温加湿双重功能，能够分别适宜于夏季、冬季的空气调节使用，解决了现有技术中溶液调湿空调系统功能单一的问题，扩展了溶液调湿空气处理系统的市场应用前景。2. The solution humidity control air treatment system of the present invention is optimized in structure, and only needs simple conversion control to realize the dual functions of cooling and dehumidification and heating and humidification, which can be respectively suitable for air conditioning in summer and winter, and solves the problem of existing problems. The single function problem of the solution humidity control air conditioning system in the technology expands the market application prospect of the solution humidity control air treatment system.
3、本发明的溶液调湿空气处理系统在降温和除湿处理的调湿溶液循环流程中，利用了第三换热器对浓度较高的调试溶液进行制冷，一方面使得浓度较高的调试溶液蒸汽压大幅减小，增大了浓度较高的调试溶液与被处理空气的蒸汽压差，从而能够有效增加浓度较高的调试溶液在溶液除湿器中对被处理空气进行降温、除湿处理的效率；另一方面，除湿处理后得到的浓度较低的调试溶液的温度也相对较低，因此浓度较低的调试溶液经过第二换热器与从溶液再生器流出的浓度较高的调湿溶液进行热传递，对浓度较高的调湿溶液进行预冷处理，使得预冷处理后的浓度较高的调湿溶液更容易在经过第三换热器时得以制冷降温，让第三换热器中冷水预热循环管路的制冷量得以充分利用，由此形成了提升溶液除湿器中降温、除湿处理效率的良性循环；同时，冷水预热循环管路中被预热的冷水吸热升温后，可以进一步加热用作生活热水，达到热能回收利用的目的。3. In the solution humidity control air treatment system of the present invention, in the circulation process of the humidity control solution for cooling and dehumidification treatment, the third heat exchanger is used to cool the debugging solution with higher concentration, on the one hand, the debugging solution with higher concentration The vapor pressure is greatly reduced, which increases the vapor pressure difference between the high-concentration debugging solution and the treated air, thereby effectively increasing the efficiency of the high-concentration debugging solution in cooling and dehumidifying the treated air in the solution dehumidifier ; On the other hand, the temperature of the lower-concentration debugging solution obtained after the dehumidification treatment is also relatively low, so the lower-concentration debugging solution passes through the second heat exchanger and the higher-concentration humidity-conditioning solution flowing out from the solution regenerator Carry out heat transfer, and pre-cool the humidity-conditioning solution with a high concentration, so that the humidity-conditioning solution with a high concentration after the pre-cooling treatment can be cooled and cooled more easily when passing through the third heat exchanger, so that the cold water in the third heat exchanger The cooling capacity of the preheating circulation pipeline can be fully utilized, thereby forming a virtuous circle that improves the efficiency of cooling and dehumidification in the solution dehumidifier; at the same time, after the preheated cold water in the cold water preheating circulation pipeline absorbs heat and heats up, Further heating is used as domestic hot water to achieve the purpose of heat energy recovery and utilization.
4、本发明的溶液调湿空气处理系统在升温和加湿处理的调湿溶液循环流程中，直接利用溶液再生器作为“加湿器”，通过被第一换热器中的地热温泉加热的浓度较低的调试溶液对被处理空气进行升温、加湿，所得到的浓度较高的调试溶液直接由补水管路补入的水分进行降温、稀释，恢复为温度、浓度较低的调湿溶液，循环过程简单，循环路径短、效率高，同时溶液除湿器、第二换热器、第三换热器都处于停用状态，有助于减少设备损耗。4. The solution humidity control air treatment system of the present invention directly uses the solution regenerator as a "humidifier" in the circulation process of the humidity control solution for heating and humidification treatment, and the concentration of the heated hot spring in the first heat exchanger is relatively high. The low-level adjustment solution heats up and humidifies the treated air, and the obtained adjustment solution with a high concentration is directly cooled and diluted by the water supplied by the water supply pipeline, and returns to a humidity-conditioning solution with a low temperature and concentration, and the cycle process Simple, short circulation path, high efficiency, while the solution dehumidifier, the second heat exchanger, and the third heat exchanger are all in a disabled state, which helps to reduce equipment loss.
5、本发明的溶液调湿空气处理系统在降温和除湿处理的空气循环流程中，并不是直接将得到的处理空气通过表冷器进行制冷，而是在通过表冷器制冷前，先将溶液除湿器送出的处理空气经过显热交换器与从排风旁通支管回风进气管进入的室内空气排风进行显热交换，使得处理空气能够先回收室内空气排风的低温显冷量得以降温后，再由表冷器制冷至送风温度，从而可以减少对表冷器的制冷消耗，有利于节省能源。5. In the air circulation process of cooling and dehumidification treatment, the solution humidity-adjusting air treatment system of the present invention does not directly refrigerate the obtained treated air through the surface cooler, but first cools the solution before cooling through the surface cooler. The treated air sent by the dehumidifier is passed through the sensible heat exchanger to exchange sensible heat with the indoor air exhaust entering from the exhaust bypass branch pipe return air intake pipe, so that the treated air can first recover the low-temperature sensible cooling capacity of the indoor air exhaust to cool down After that, the surface cooler is cooled to the temperature of the air supply, thereby reducing the cooling consumption of the surface cooler and helping to save energy.
6、在本发明的溶液调湿空气处理系统中，对被处理空气的调湿处理和调温处理相互分开，表冷器无需负担调湿负荷，仅用于对控制通入室内的送风温度，因此不会产生凝水，可以有效防止细菌的滋生和繁殖，并且能够提高表冷器的制冷系数。6.

本发明利用地热温泉资源的溶液调湿空气处理系统，既可以在夏季用于对室内空气进行降温和除湿处理，又可以在冬季用于对室内空气进行升温和加湿处理。The solution humidity-adjusting air treatment system utilizing geothermal hot spring resources of the present invention can be used for cooling and dehumidifying the indoor air in summer, and can be used for heating and humidifying the indoor air in winter.
在夏季，利用本发明的溶液调湿空气处理系统对室内空气进行降温和除湿处理的方法如下。关闭第一水阀8和第二水阀10，开启第三水阀14和第四水阀16，运行第一循环溶液泵11、第二循环溶液泵15、第一风机32以及第二风机33，将第一选通阀20选择连通至与室外相通的第一排气管21，将第二选通阀24选择连通至除湿送风进气管17，将第三选通阀29选择连通至第二回风旁通支管26，并通过调节气流控制阀30控制回风量，通过调节表冷器4的制冷量控制通入室内的送风温度；In summer, the method for cooling and dehumidifying the indoor air by using the solution humidity-adjusting air treatment system of the present invention is as follows. Close the first water valve 8 and the second water valve 10, open the third water valve 14 and the fourth water valve 16, and run the first circulating solution pump 11, the second circulating solution pump 15, the first fan 32 and the second fan 33 Selectively connect the first selector valve 20 to the first exhaust pipe 21 communicating with the outside, selectively communicate the second selector valve 24 to the dehumidification and supply air intake pipe 17, and selectively communicate the third selector valve 29 to the first exhaust pipe 21 connected to the outside. The second return air bypasses the branch pipe 26, and controls the return air volume by adjusting the air flow control valve 30, and controls the temperature of the air supply into the room by adjusting the cooling capacity of the surface cooler 4;
降温和除湿处理的调湿溶液循环流程为：在第二循环溶液泵15的驱动下，浓度较高的调湿溶液从溶液再生器的再生溶液出口管1a流出，经过第二换热器6与从溶液除湿器的调湿溶液出口管2b流出的浓度较低的调湿溶液进行热传递，然后浓度较高的调湿溶液再经过第三换热器7对冷水预热循环管路的冷水进行预热，从而被冷水预热循环管路的冷水制冷的浓度较高的调湿溶液从调湿溶液入口管2a进入溶液除湿器2，对通过溶液除湿器2的被处理空气进行除湿处理；而后，在第一循环溶液泵11的驱动下，除湿处理得到的浓度较低的调湿溶液从溶液除湿器的调湿溶液出口管2b流出，经过第二换热器6与浓度较高的调湿溶液进行热传递，然后浓度较低的调湿溶液再经过第一换热器5被地热温泉加热升温后，从再生溶液入口管1b进入溶液再生器1，由经过溶液再生器1的新风空气将浓度较低的调湿溶液的水分带走并从第一排气管21排出至室外，从而再生得到浓度较高的调湿溶液；如此循环，形成降温和除湿处理的调湿溶液循环流程；The circulation process of the humidity control solution for the cooling and dehumidification treatment is as follows: driven by the second circulation solution pump 15, the humidity control solution with higher concentration flows out from the regeneration solution outlet pipe 1a of the solution regenerator, and passes through the second heat exchanger 6 and The humidity-conditioning solution with a lower concentration flowing out from the humidity-conditioning solution outlet pipe 2b of the solution dehumidifier performs heat transfer, and then the humidity-conditioning solution with a higher concentration passes through the third heat exchanger 7 to cool the cold water in the cold water preheating circulation pipeline Preheating, so that the humidity-conditioning solution with higher concentration refrigerated by the cold water of the cold water preheating circulation line enters the solution dehumidifier 2 from the humidity-conditioning solution inlet pipe 2a, and dehumidifies the treated air passing through the solution dehumidifier 2; and then , driven by the first circulating solution pump 11, the humidity-conditioning solution with a lower concentration obtained from the dehumidification treatment flows out from the humidity-conditioning solution outlet pipe 2b of the solution dehumidifier, and passes through the second heat exchanger 6 and the humidity-conditioning solution with a higher concentration. The solution performs heat transfer, and then the humidity-adjusting solution with a lower concentration passes through the first heat exchanger 5 and is heated by the geothermal hot spring, and then enters the solution regenerator 1 from the regeneration solution inlet pipe 1b, and is regenerated by the fresh air passing through the solution regenerator 1. The moisture of the humidity-conditioning solution with a lower concentration is taken away and discharged from the first exhaust pipe 21 to the outside, so as to regenerate the humidity-conditioning solution with a higher concentration; such circulation forms a circulation process of the humidity-conditioning solution for cooling and dehumidification treatment;
降温和除湿处理空气循环流程为：湿度较高室内空气由回风进气管27进入，通过回风出气管28上的气流控制阀30控制回风量，使得一部分室内空气作为回风经由回风出气管28进入第二回风旁通支管26，另一部分室内空气作为排风进入排风旁通支管31，经过显热交换器3与来自除湿送风进气管17的处理空气进行显热交换，然后排出至室外；而后，在第二风机的驱动下，回风与第二新风进气管23的新风空气合流形成被处理空气，通过溶液除湿器2进行除湿处理，得到的湿度较低的处理空气由第二新风输出管2c输送至除湿送风进气管17，然后湿度较低的处理空气经过显热交换器3与从排风旁通支管31进入的排风进行显热交换后，再经过表冷器4降温至送风温度后，从除湿送风出气管18a通入室内；如此循环，形成降温和除湿处理的空气循环流程。The cooling and dehumidification treatment air circulation process is as follows: indoor air with high humidity enters through the return air inlet pipe 27, and the return air volume is controlled through the airflow control valve 30 on the return air outlet pipe 28, so that part of the indoor air is used as return air through the return air outlet pipe 28 enters the second return air bypass branch pipe 26, and another part of the indoor air enters the exhaust air bypass branch pipe 31 as exhaust air, passes through the sensible heat exchanger 3 to exchange sensible heat with the treated air from the dehumidification air supply inlet pipe 17, and then discharges Then, under the drive of the second blower fan, the fresh air of the return air and the second fresh air inlet pipe 23 merges to form the treated air, and the dehumidification process is carried out by the solution dehumidifier 2, and the treated air with lower humidity is obtained by the second fresh air intake pipe 23. The second fresh air output pipe 2c is sent to the dehumidification air supply inlet pipe 17, and then the treated air with low humidity passes through the sensible heat exchanger 3 to exchange sensible heat with the exhaust air entering from the exhaust bypass branch pipe 31, and then passes through the surface cooler 4. After cooling down to the air supply temperature, the dehumidification air supply outlet pipe 18a is passed into the room; such circulation forms an air circulation process for cooling and dehumidification treatment.
通过上述对室内空气的降温和除湿处理流程，可以看到，本发明的溶液调湿空气处理系统在降温和除湿处理的调湿溶液循环流程中，利用了第三换热器对浓度较高的调试溶液进行制冷，一方面使得浓度较高的调试溶液蒸汽压大幅减小，增大了浓度较高的调试溶液与被处理空气的蒸汽压差，从而能够有效增加浓度较高的调试溶液在溶液除湿器中对被处理空气进行除湿处理的效率，同时增强了调试溶液对被处理空气的降温处理能力；另一方面，除湿处理后得到的浓度较低的调试溶液的温度也相对较低，因此浓度较低的调试溶液经过第二换热器与从溶液再生器流出的浓度较高的调湿溶液进行热传递，对浓度较高的调湿溶液进行预冷处理，使得预冷处理后的浓度较高的调湿溶液更容易在经过第三换热器时得以制冷降温，让第三换热器中冷水预热循环管路的制冷量得以充分利用，由此形成了提升溶液除湿器中降温、除湿处理效率的良性循环；同时，冷水预热循环管路中被预热的冷水吸热升温后，可以进一步加热（例如将被预热的冷水通入至热水器）用作生活热水，达到热能回收利用的目的。此外，还可以看到，本发明的溶液调湿空气处理系统在降温和除湿处理的空气循环流程中，被处理空气在溶液除湿器中被降温、除湿，得到的湿度较低的处理空气，但由于处理空气是由部分回风与温度较高的新风混合构成的被处理空气加以除湿处理而得到的，因此处理空气相对于室内空气而言温度依然较高，还需要进一步制冷到送风温度；然而，本发明的溶液调湿空气处理系统在降温和除湿处理的空气循环流程中，并不是直接将得到的处理空气通过表冷器进行制冷，而是在通过表冷器制冷前，先将溶液除湿器送出的处理空气经过显热交换器与从排风旁通支管回风进气管进入的室内空气排风进行显热交换，使得处理空气能够先回收室内空气排风的低温显冷量得以降温后，再由表冷器制冷至送风温度，从而可以减少对表冷器的制冷消耗，有利于节省能源。Through the above-mentioned cooling and dehumidification treatment process for indoor air, it can be seen that the solution humidity control air treatment system of the present invention utilizes the third heat exchanger in the humidity control solution circulation process of cooling and dehumidification treatment The debugging solution is refrigerated, on the one hand, the vapor pressure of the higher-concentration debugging solution is greatly reduced, and the vapor pressure difference between the higher-concentration debugging solution and the treated air is increased, thereby effectively increasing the concentration of the higher-concentration debugging solution in the solution. The efficiency of the dehumidification treatment of the treated air in the dehumidifier also enhances the ability of the debugging solution to cool the treated air; on the other hand, the temperature of the lower concentration of the debugging solution obtained after the dehumidification treatment is relatively low, so The lower-concentration debugging solution passes through the second heat exchanger to conduct heat transfer with the higher-concentration humidity-conditioning solution flowing out of the solution regenerator, and performs pre-cooling treatment on the higher-concentration humidity-conditioning solution, so that the concentration after pre-cooling treatment is higher The humidity-adjusting solution is easier to cool and cool down when passing through the third heat exchanger, so that the cooling capacity of the cold water preheating circulation pipeline in the third heat exchanger can be fully utilized, thus forming a solution for cooling and dehumidification in the dehumidifier of the lifting solution A virtuous cycle of treatment efficiency; at the same time, after the preheated cold water in the cold water preheating circulation pipeline absorbs heat and rises in temperature, it can be further heated (for example, the preheated cold water is passed into the water heater) and used as domestic hot water to achieve heat energy recovery purpose of use. In addition, it can also be seen that in the air circulation process of cooling and dehumidification treatment in the solution humidity-adjusting air treatment system of the present invention, the treated air is cooled and dehumidified in the solution dehumidifier, and the treated air with lower humidity is obtained, but Since the processed air is obtained by dehumidifying the processed air which is composed of part of the return air mixed with higher temperature fresh air, the temperature of the processed air is still higher than that of the indoor air, and it needs to be further cooled to the supply air temperature; However, in the air circulation process of the cooling and dehumidification treatment, the solution humidity-adjusting air treatment system of the present invention does not directly refrigerate the obtained treated air through the surface cooler, but first cools the solution before cooling through the surface cooler. The treated air sent by the dehumidifier is passed through the sensible heat exchanger to exchange sensible heat with the indoor air exhaust entering from the exhaust bypass branch pipe return air intake pipe, so that the treated air can first recover the low-temperature sensible cooling capacity of the indoor air exhaust to cool down Afterwards, the surface cooler is cooled to the temperature of the air supply, thereby reducing the cooling consumption of the surface cooler and helping to save energy.
在冬季，利用本发明的溶液调湿空气处理系统对室内空气进行升温和加湿处理的方法如下。开启第一水阀8和第二水阀10，关闭第三水阀14和第四水阀16，运行第一循环溶液泵11和第一风机32，关闭第二循环溶液泵15和第二风机33，将第一选通阀20选择连通至加湿送风出气管18b，将第二选通阀24选择连通至与室外相通的第二排气管25，将第三选通阀29选择连通至第一回风旁通支管22，并通过调节气流控制阀30控制回风量，通过调节表冷器4的加热量控制通入室内的送风温度；In winter, the method for heating and humidifying the indoor air by using the solution humidity-adjusting air treatment system of the present invention is as follows. Open the first water valve 8 and the second water valve 10, close the third water valve 14 and the fourth water valve 16, run the first circulating solution pump 11 and the first fan 32, and close the second circulating solution pump 15 and the second fan 33. The first selector valve 20 is selectively connected to the humidification air outlet pipe 18b, the second selector valve 24 is selectively connected to the second exhaust pipe 25 connected to the outdoor, and the third selector valve 29 is selectively connected to The first return air bypasses the branch pipe 22, and controls the return air volume by adjusting the air flow control valve 30, and controls the temperature of the air supply into the room by adjusting the heating capacity of the surface cooler 4;
升温和加湿处理的调湿溶液循环流程为：在第一循环溶液泵11的驱动下，浓度较低的调湿溶液从溶液再生器的再生溶液出口管1a流出，经过第一换热器5被地热温泉加热升温后，从再生溶液入口管1b进入溶液再生器1，对通过溶液再生器1的被处理空气进行加湿处理，由被处理空气将浓度较低的调湿溶液的水分带走并从第一排气管21排出至室外，从而再生得到浓度较高的调湿溶液回到溶液再生器1的储液箱中，同时由补水管路9补入水分至溶液再生器1的储液箱，将浓度较高的调湿溶液稀释为浓度较低的调湿溶液；如此循环，形成升温和加湿处理的调湿溶液循环流程；The circulation process of the humidity-conditioning solution for heating and humidification treatment is as follows: driven by the first circulation solution pump 11, the humidity-conditioning solution with a relatively low concentration flows out from the outlet pipe 1a of the regeneration solution of the solution regenerator, and passes through the first heat exchanger 5 to be After the geothermal hot spring is heated and heated, it enters the solution regenerator 1 from the regeneration solution inlet pipe 1b, and performs humidification treatment on the treated air passing through the solution regenerator 1, and the moisture of the humidity-conditioning solution with a lower concentration is taken away by the treated air and removed from the The first exhaust pipe 21 is discharged to the outside, so that the humidity-conditioning solution with high concentration can be regenerated and returned to the liquid storage tank of the solution regenerator 1, and at the same time, water is replenished to the liquid storage tank of the solution regenerator 1 through the water replenishment pipeline 9 , diluting the humidity-adjusting solution with a higher concentration into a humidity-adjusting solution with a lower concentration; such a cycle forms a circulation process of the humidity-conditioning solution for heating and humidification;
升温和加湿处理空气循环流程为：湿度较低室内空气由回风进气管27进入，通过回风出气管上28的气流控制阀30控制回风量，使得一部分室内空气作为回风经由回风出气管28进入第一回风旁通支管22，另一部分室内空气作为排风进入排风旁通支管31，经过显热交换器后排出至室外；而后，在第一风机的驱动下，回风与第一新风进气管19的新风空气合流形成被处理空气，通过溶液再生器1进行加湿处理，得到的温度、湿度较高的处理空气由第一新风输出管1c输送至加湿送风出气管18b，通入室内；如此循环，形成升温和加湿处理的空气循环流程。The air circulation process for heating and humidifying treatment is as follows: indoor air with low humidity enters through the return air inlet pipe 27, and controls the return air volume through the airflow control valve 30 on the return air outlet pipe 28, so that part of the indoor air is used as return air through the return air outlet pipe 28 enters the first return air bypass branch pipe 22, and another part of indoor air enters the exhaust air bypass branch pipe 31 as exhaust air, and is discharged to the outside after passing through the sensible heat exchanger; then, driven by the first fan, the return air and the second The fresh air of a fresh air inlet pipe 19 merges to form the treated air, which is humidified by the solution regenerator 1, and the obtained treated air with high temperature and humidity is transported to the humidification and air supply outlet pipe 18b by the first fresh air output pipe 1c, and passed through Into the room; such a cycle forms an air circulation process of heating and humidification.
通过上述对室内空气的升温和加湿处理流程，可以看到，本发明的溶液调湿空气处理系统在升温和加湿处理的调湿溶液循环流程中，直接利用溶液再生器作为“加湿器”，通过被第一换热器中的地热温泉加热的浓度较低的调试溶液对被处理空气进行升温、加湿，所得到的浓度较高的调试溶液直接由补水管路补入的水分进行降温、稀释，恢复为温度、浓度较低的调湿溶液，循环过程简单，循环路径短、效率高，同时溶液除湿器、第二换热器、第三换热器都处于停用状态，有助于减少设备损耗。Through the above-mentioned heating and humidification treatment process for indoor air, it can be seen that the solution humidity control air treatment system of the present invention directly uses the solution regenerator as a "humidifier" in the humidity control solution circulation process of the heating and humidification treatment. The low-concentration debugging solution heated by the geothermal hot spring in the first heat exchanger heats up and humidifies the air to be treated, and the obtained high-concentration debugging solution is directly cooled and diluted by the water supplied by the water supply pipeline. Return to the humidity-conditioning solution with low temperature and concentration, the circulation process is simple, the circulation path is short, and the efficiency is high. At the same time, the solution dehumidifier, the second heat exchanger, and the third heat exchanger are all in a disabled state, which helps to reduce equipment loss.
不仅如此，通过上述对本发明溶液调湿空气处理系统的结构和调湿处理流程的整体说明，还可以看到，本发明的溶液调湿空气处理系统还直接利用了我国藏量较为丰富的地热温泉资源作为于实现调试溶液再生的热源，避免了使用电能等转换能源，不仅有助于减少能源的转换损耗、提高能源利用率，还有助于减少因能源转换滋生的污染排放，实现了节能减排；并且，本发明的溶液调湿空气处理系统通过结构优化，只需要进行简单的转换控制，就能够实现降温除湿、升温加湿双重功能，能够分别适宜于夏季、冬季的空气调节使用，解决了现有技术中溶液调湿空调系统功能单一的问题，扩展了溶液调湿空气处理系统的市场应用前景。Not only that, through the above-mentioned overall description of the structure and humidity control process of the solution humidity control air treatment system of the present invention, it can also be seen that the solution humidity control air treatment system of the present invention also directly utilizes the relatively abundant geothermal hot springs in my country Resources are used as the heat source for the regeneration of the debugging solution, avoiding the use of conversion energy such as electric energy, which not only helps to reduce energy conversion losses and improve energy utilization, but also helps to reduce pollution emissions caused by energy conversion, achieving energy saving and reduction. In addition, the solution humidity-adjusting air treatment system of the present invention can achieve the dual functions of cooling and dehumidification and heating and humidification through structural optimization, and can realize the dual functions of cooling and dehumidification and heating and humidification, and can be used for air conditioning in summer and winter respectively, solving the problem of The problem of the single function of the solution humidity control air conditioning system in the prior art expands the market application prospect of the solution humidity control air treatment system.
