The principle is that the heat source tower heat pump operates in cooling mode in summer. The heat source tower is equivalent to the cooling tower of the water-cooled chiller. The heat source tower heat pump system realizes the high efficiency of the water-cooled chiller. The solution exchanges heat with the air in the heat source tower, and the solution absorbs the heat in the air as the low-level heat source of the heat pump unit. It will enter the solution, dilute the concentration of the solution, and cause the freezing point of the solution to rise. In order to ensure the safety and reliability of the system operation, it is necessary to adjust the water entering the solution, that is, to control the concentration of the solution, so as to ensure the stability of the freezing point of the solution. To control the concentration of the solution, the main method is to regenerate the solution. At the same time, the regeneration process of the solution is a process that needs to absorb heat. Therefore, what regeneration method to adopt, how to obtain the regeneration heat source of the solution, and how to realize the regeneration heat Efficient utilization is of great significance to improve the performance of the heat source tower heat pump system and ensure the safe and reliable operation of the system.
另外，常规的热源塔热泵系统具有类似水冷冷水机组形式，在热源塔中吸收的热量利用溶液作为输送工作介质输送给机组的蒸发器，而这过程中，需要消耗较大的溶液输送泵功，能否减少或降低这部分泵功对提供系统整体能效也具有重要意义。In addition, the conventional heat source tower heat pump system has a form similar to that of a water-cooled chiller. The heat absorbed in the heat source tower uses the solution as the working medium to transport it to the evaporator of the unit. In this process, a large amount of solution delivery pump work is required. Whether this part of the pump work can be reduced or lowered is also of great significance for improving the overall energy efficiency of the system.

Heating operation mode 1: heat source tower heat pumps operate during winter heating. When the partial pressure of water vapor on the surface, that is, when the water enters the air from the solution, the low-temperature and low-pressure refrigerant gas in the gas-liquid separator is sucked by the compressor, compressed and discharged, and enters the first heat exchanger through the four-way valve. The refrigerant releases heat in the first heat exchanger, condenses itself into a liquid to produce hot water for heating, then passes through the first one-way valve, the first solenoid valve (at this time the second solenoid valve is closed), and then passes through the liquid storage After the filter, filter, and electronic expansion valve, the refrigerant is throttled and depressurized, and enters the packed coil heat exchanger through the fourth one-way valve in gas-liquid two-phase, and the refrigerant in the packed coil heat exchanger After exchanging heat with the solution, the refrigerant evaporates and absorbs heat.

As the volume increases, the air comes out of the packed coil heat exchanger and enters the filler. Because there is no solution flowing out of the second liquid distribution device, the air will directly pass through the filler and enter the anti-floating liquid device. The small droplets of the solution in the air are intercepted, and then After the air comes out of the anti-floating liquid device, it is sucked by the fan, and after being pressurized, it is discharged from the compound heat source tower. In the cold and hot water circuit, hot water enters the first heat exchanger from the cold and hot water return end of the unit, where the hot water exchanges heat with the refrigerant. After the temperature rises, it comes out of the first heat exchanger and is fed by the unit The cold and hot water supply end flows out of the unit.
制热运行模式二：当空气中湿度较大，在复式热源塔中的空气中的水蒸汽分压力大于溶液表面的水蒸汽分压力时，即水分是从空气进入到溶液中时，制冷剂回路中，气液分离器中低温低压的制冷剂气体被压缩机吸入、压缩后排出，通过四通阀进入第一换热器，制冷剂在第一换热器中放出热量，冷凝成液体，制取供热热水，制冷剂从第一换热器中出来后，通过第一单向阀、第二电磁阀（此时第一电磁阀关闭）后进入第二换热器，在第二换热器中与溶液进行换热，制冷剂放出热量，进一步过冷，从第二换热器出来后依次经过储液器、过滤器、电子膨胀阀，制冷剂被节流降压，以气液两相通过第四单向阀进入填料式盘管换热器，在填料式盘管换热器中与溶液换热，进行蒸发吸热，制冷剂完全蒸发后从填料式盘管换热器出来流经四通阀进入气液分离器，最后再次被压缩机吸入，重新被压缩参与循环。此时溶液回路中充灌着溶液，集液槽中溶液从复式热源塔塔体第二输出端出来后进入溶液泵，经过溶液泵加压后进入电动三通调节阀，溶液在电动三通调节阀中被分成两路，一路从电动三通调节阀第一输出端流出进入第一布液装置，另外一路从电动三通调节阀第二输出端流出进入第二换热器中，溶液在第二换热器中与液体制冷剂进行换热，吸收热量，温度升高后，从第二换热器中流出进入第二布液装置，溶液被均匀喷淋到填料中，溶液在填料中与空气进行热质交换，因此时溶液温度较高，溶液中的水蒸汽分压力大于空气中水蒸汽分压力，溶液中水分进入空气中，溶液浓度将提高，实现溶液再生，溶液从填料中流出后，与从第一布液装置中均匀布撒的溶液混合后一道进入到填料式盘管换热器，溶液在其中与空气进行换热，溶液从空气中吸收热量，温度升高，同时空气中的水蒸汽分压力大于溶液表面的水蒸汽分压力，空气中水分进入溶液，溶液吸收这部分潜热，溶液浓度将降低。与此同时，溶液也与填料式盘管换热器中的制冷剂换热，溶液放出热量，使制冷剂吸热蒸发，溶液的温度将降低。溶液从填料式盘管换热器出来后落入集液槽中，然后再次从复式热源塔塔体第二输出端流出，如此循环。Heating operation mode 2: When the humidity in the air is high and the partial pressure of water vapor in the air in the double heat source tower is greater than the partial pressure of water vapor on the surface of the solution, that is, when the water enters the solution from the air, the refrigerant circuit In the process, the low-temperature and low-pressure refrigerant gas in the gas-liquid separator is sucked by the compressor, compressed and then discharged, and enters the first heat exchanger through the four-way valve. The refrigerant releases heat in the first heat exchanger, condenses into liquid, and produces After the hot water is taken for heating, the refrigerant comes out of the first heat exchanger, passes through the first one-way valve and the second solenoid valve (the first solenoid valve is closed at this time), and then enters the second heat exchanger. Heat exchange with the solution in the heat exchanger, the refrigerant releases heat and is further subcooled. After coming out of the second heat exchanger, it passes through the liquid receiver, filter, and electronic expansion valve in sequence. The two phases enter the packed coil heat exchanger through the fourth one-way valve, exchange heat with the solution in the packed coil heat exchanger, evaporate and absorb heat, and come out of the packed coil heat exchanger after the refrigerant is completely evaporated It flows through the four-way valve into the gas-liquid separator, and finally is sucked into the compressor again, and is recompressed to participate in the cycle. At this time, the solution circuit is filled with solution, and the solution in the liquid collection tank enters the solution pump after coming out from the second output end of the compound heat source tower body, and enters the electric three-way regulating valve after being pressurized by the solution pump, and the solution is adjusted in the electric three-way The valve is divided into two paths, one path flows out from the first output end of the electric three-way regulating valve and enters the first liquid distribution device, and the other path flows out from the second output end of the electric three-way regulating valve into the second heat exchanger. The second heat exchanger exchanges heat with the liquid refrigerant to absorb heat. After the temperature rises, it flows out of the second heat exchanger and enters the second liquid distribution device. The solution is evenly sprayed into the filler, and the solution is mixed with the filler in the filler. The air performs heat and mass exchange, so the temperature of the solution is high, and the partial pressure of water vapor in the solution is greater than the partial pressure of water vapor in the air. When the water in the solution enters the air, the concentration of the solution will increase, and the solution will be regenerated. After the solution flows out of the filler , mixed with the solution uniformly distributed from the first liquid distribution device, it enters the packed coil heat exchanger together, where the solution exchanges heat with the air, the solution absorbs heat from the air, and the temperature rises, while the air in the The partial pressure of water vapor is greater than the partial pressure of water vapor on the surface of the solution, the water in the air enters the solution, the solution absorbs this part of latent heat, and the concentration of the solution will decrease. At the same time, the solution also exchanges heat with the refrigerant in the packed coil heat exchanger, the solution releases heat, the refrigerant absorbs heat and evaporates, and the temperature of the solution decreases. After the solution comes out of the packed coil heat exchanger, it falls into the liquid collection tank, and then flows out from the second output end of the multiple heat source tower again, and so on.
空气回路中，空气从复式热源塔塔体下部进入复式热源塔，然后首先进入填料式盘管换热器，在填料式盘管换热器中与溶液进行热质交换，因空气中的水蒸汽分压力大于溶液表面的水蒸汽分压力，空气温度降低同时含湿量减少，空气从填料式盘管换热器出来后，进入填料中，此时填料中的溶液温度较高，而空气经过填料式盘管换热器后温度降低，含湿量减少，因此，填料中溶液的表面水蒸汽分压力远大于空气中的水蒸汽分压力，此时溶液中的水分将大量进入空气，溶液的浓度得到提高，空气的温度和含湿量将大幅上升，空气从填料中出来后经过防飘液装置，空气中溶液小液滴被拦截，然后空气从防飘液装置出来后被风机吸入，加压后排出复式热源塔。In the air circuit, the air enters the complex heat source tower from the lower part of the complex heat source tower body, and then first enters the packed coil heat exchanger, where it exchanges heat and mass with the solution, due to the water vapor in the air The partial pressure is greater than the partial pressure of water vapor on the surface of the solution, the air temperature decreases and the moisture content decreases at the same time. After the air comes out of the packed coil heat exchanger, it enters the packing. At this time, the temperature of the solution in the packing is higher, and the air passes through the packing. After the type coil heat exchanger, the temperature decreases and the moisture content decreases. Therefore, the partial pressure of water vapor on the surface of the solution in the filler is much higher than that in the air. At this time, a large amount of water in the solution will enter the air, and the concentration of the solution will If the temperature and moisture content of the air are increased, the air will pass through the anti-floating liquid device after coming out of the filler, and the small liquid droplets in the air will be intercepted, and then the air will be sucked by the fan after coming out of the anti-floating liquid device, pressurized Finally, the compound heat source tower is discharged.
冷热水回路中供热热水从机组的冷热水回水端进入第一换热器中，热水在其中与制冷剂换热，温度升高后，从第一换热器出来，由机组的冷热水供水端流出机组。In the cold and hot water circuit, the hot water for heating enters the first heat exchanger from the cold and hot water return end of the unit, where the hot water exchanges heat with the refrigerant. After the temperature rises, it comes out of the first heat exchanger and is The cold and hot water supply end of the unit flows out of the unit.
在系统制热运行模式二过程中，1）溶液再生利用的是液体制冷剂冷却实现过冷所放出的热量，通过控制电动三通调节阀，实现对分别进入第一布液装置和第二布液装置的溶液流量进行调节，即调节进入填料中再生的溶液量，从而实现对复式热源塔中溶液浓度的控制；2）利用填料与填料式盘管换热器在空气回路上串联，实现了空气通过填料式盘管换热器为热泵系统提供低位热源的同时，利用从填料式盘管换热器出来的空气的低温和低湿度，为溶液再生提供好的环境，实现溶液的更好再生，使系统获得高效制热效率的同时，具有最佳的溶液再生性能，保持系统运行安全可靠。 In the second process of system heating operation mode, 1) solution regeneration utilizes the heat released by liquid refrigerant cooling to achieve supercooling. The solution flow rate of the liquid device is adjusted, that is, the amount of solution regenerated into the filler is adjusted, so as to realize the control of the solution concentration in the compound heat source tower; 2) The filler and the packed coil heat exchanger are connected in series on the air circuit to realize While the air passes through the packed coil heat exchanger to provide a low-level heat source for the heat pump system, the low temperature and low humidity of the air coming out of the packed coil heat exchanger are used to provide a good environment for solution regeneration and achieve better regeneration of the solution , so that the system can obtain high heating efficiency while having the best solution regeneration performance to keep the system safe and reliable.

制热运行模式二：当空气中湿度较大，在复式热源塔中的空气中的水蒸汽分压力大于溶液表面的水蒸汽分压力时，即水分是从空气进入到溶液中时，制冷剂回路中，气液分离器14中低温低压的制冷剂气体被压缩机1吸入、压缩后排出，通过四通阀2进入第一换热器3，制冷剂在第一换热器3中放出热量，冷凝成液体，制取供热热水，制冷剂从第一换热器3中出来后，通过第一单向阀4、第二电磁阀7（此时第一电磁阀6关闭）后进入第二换热器8，在第二换热器8中与溶液进行换热，制冷剂放出热量，进一步过冷，从第二换热器8出来后依次经过储液器9、过滤器10、电子膨胀阀11，制冷剂被节流降压，以气液两相通过第四单向阀13进入填料式盘管换热器17，在填料式盘管换热器17中与溶液换热，进行蒸发吸热，制冷剂完全蒸发后从填料式盘管换热器17出来流经四通阀2进入气液分离器14，最后再次被压缩机1吸入，重新被压缩参与循环。此时溶液回路中充灌着溶液，集液槽16中溶液从复式热源塔塔体第二输出端24e出来后进入溶液泵23，经过溶液泵23加压后进入电动三通调节阀15，溶液在电动三通调节阀15中被分成两路，一路从电动三通调节阀第一输出端15b流出进入第一布液装置18，另外一路从电动三通调节阀第二输出端15c流出进入第二换热器8中，溶液在第二换热器8中与液体制冷剂进行换热，吸收热量，温度升高后，从第二换热器8中流出进入第二布液装置20，溶液被均匀喷淋到填料19中，溶液在填料19中与空气进行热质交换，因此时溶液温度较高，溶液中的水蒸汽分压力大于空气中水蒸汽分压力，溶液中水分进入空气中，溶液浓度将提高，实现溶液再生，溶液从填料19中流出后，与从第一布液装置18中均匀布撒的溶液混合后一道进入到填料式盘管换热器17，溶液在其中与空气进行换热，溶液从空气中吸收热量，温度升高，同时空气中的水蒸汽分压力大于溶液表面的水蒸汽分压力，空气中水分进入溶液，溶液吸收这部分潜热，溶液浓度将降低。与此同时，溶液也与填料式盘管换热器17中的制冷剂换热，溶液放出热量，使制冷剂吸热蒸发，溶液的温度将降低。溶液从填料式盘管换热器17出来后落入集液槽16中，然后再次从复式热源塔塔体第二输出端流出24e，如此循环。Heating operation mode 2: When the humidity in the air is high and the partial pressure of water vapor in the air in the double heat source tower is greater than the partial pressure of water vapor on the surface of the solution, that is, when the water enters the solution from the air, the refrigerant circuit In the process, the low-temperature and low-pressure refrigerant gas in the gas-liquid separator 14 is sucked by the compressor 1, compressed and then discharged, and enters the first heat exchanger 3 through the four-
空气回路中，空气从复式热源塔塔体24下部进入复式热源塔，然后首先进入填料式盘管换热器17，在填料式盘管换热器17中与溶液进行热质交换，因空气中的水蒸汽分压力大于溶液表面的水蒸汽分压力，空气温度降低同时含湿量减少，空气从填料式盘管换热器17出来后，进入填料19中，此时填料19中的溶液温度较高，而空气经过填料式盘管换热器17后温度降低，含湿量减少，因此，填料19中溶液的表面水蒸汽分压力远大于空气中的水蒸汽分压力，此时溶液中的水分将大量进入空气，溶液的浓度得到提高，空气的温度和含湿量将大幅上升，空气从填料19中出来后经过防飘液装置21，空气中溶液小液滴被拦截，然后空气从防飘液装置21出来后被风机22吸入，加压后排出复式热源塔。In the air circuit, the air enters the compound heat source tower from the lower part of the compound heat
冷热水回路中供热热水从机组的冷热水回水端进入第一换热器3中，热水在其中与制冷剂换热，温度升高后，从第一换热器3出来，由机组的冷热水供水端流出机组。In the cold and hot water circuit, the hot water for heating enters the first heat exchanger 3 from the cold and hot water return end of the unit, where the hot water exchanges heat with the refrigerant, and after the temperature rises, it comes out of the first heat exchanger 3 , flows out of the unit from the cold and hot water supply end of the unit.
在系统制热运行模式二过程中，1）溶液再生利用的是液体制冷剂冷却实现过冷所放出的热量，通过控制电动三通调节阀15，实现对分别进入第一布液装置18和第二布液装置20的溶液流量进行调节，即调节进入填料19中再生的溶液量，从而实现对复式热源塔中溶液浓度的控制；2）利用填料19与填料式盘管换热器17在空气回路上串联，实现了空气通过填料式盘管换热器17为热泵系统提供低位热源的同时，利用从填料式盘管换热器17出来的空气的低温和低湿度，为溶液再生提供好的环境，实现溶液的更好再生，使系统获得高效制热效率的同时，具有最佳的溶液再生性能，保持系统运行安全可靠。In the second process of system heating operation mode, 1) solution regeneration utilizes the heat released by liquid refrigerant cooling to achieve supercooling. The solution flow rate of the second liquid distribution device 20 is adjusted, that is, the amount of solution regenerated into the packing 19 is adjusted, thereby realizing the control of the solution concentration in the compound heat source tower; 2) using the packing 19 and the packed coil heat exchanger 17 in the air The circuit is connected in series to realize that while the air passes through the packed coil heat exchanger 17 to provide a low-level heat source for the heat pump system, at the same time, the low temperature and low humidity of the air coming out of the packed coil heat exchanger 17 are used to provide good solution regeneration. Environment, to achieve better regeneration of the solution, so that the system can achieve high heating efficiency, and at the same time have the best solution regeneration performance, and keep the system safe and reliable.
