一种带双通道装置的空调室内壁挂机An air-conditioning indoor wall-mounted unit with a dual-channel device

技术领域technical field

本发明属于空调制冷技术领域，涉及一种空调室内壁挂机，尤其涉及一种带双通道装置的空调室内壁挂机。The invention belongs to the technical field of air-conditioning and refrigeration, and relates to an air-conditioning indoor wall-mounted machine, in particular to an air-conditioning indoor wall-mounted machine with a dual-channel device.

背景技术Background technique

现阶段住宅空调已经越来越普及，集中的中央空调系统具有向室内提供新风的功能，但对于大多数家庭用户而言，其所用的分体空调机不具有送新风功能，导致室内空气污浊。冬季工况下，由于热空气上浮特性，大量热积聚在房间上方，房间上热下冷，形成了较大的温度梯度。改善上热下冷的一般做法是让送风口需要朝下送出气流并保持一定的速度，由于家用空间较为狭小，下送气流往往使居住域人们感到吹风感。Residential air conditioners are becoming more and more popular at this stage. The centralized central air conditioning system has the function of providing fresh air to the room. However, for most home users, the split air conditioners they use do not have the function of sending fresh air, resulting in dirty indoor air. In winter working conditions, due to the floating characteristics of hot air, a large amount of heat accumulates above the room, and the room is hot at the top and cool at the bottom, forming a large temperature gradient. The general way to improve top heat and bottom cooling is to let the air outlets need to send airflow downwards and maintain a certain speed. Because the domestic space is relatively small, the downward airflow often makes people in the living area feel windy.

现有空调技术中，公告号为1594998A的中国发明专利，名称为《分体式空调智能化新风引入装置》给出了智能化引入新风的思路，未对房间气流组织合理优化提供思路。In the existing air-conditioning technology, the Chinese invention patent with the announcement number of 1594998A, titled "Intelligent fresh air introduction device for split-type air conditioner" provides ideas for intelligently introducing fresh air, but does not provide ideas for rational optimization of room airflow organization.

此外，公告号为101307940A的中国发明专利，名称为《带新风及低温新风装置的分体式空气调节器》提出了新风管道和壁挂式分体机相结合的引进新风措施，其新风管道位于室内机后，由于大部分室内分体机安装在内墙之上，外墙安装室内机对大部分家庭来讲难以实现，并且系统过大，控制复杂。In addition, the Chinese invention patent with the announcement number 101307940A titled "Separate Air Conditioner with Fresh Air and Low-temperature Fresh Air Device" proposes a measure of introducing fresh air by combining the fresh air duct and the wall-mounted split unit. The fresh air duct is located in the indoor unit. Finally, because most of the indoor split units are installed on the inner wall, it is difficult for most families to install indoor units on the outer wall, and the system is too large and the control is complicated.

如图2所示，组合新风管1包括室外防雨防风罩11、矩形新风管12、冷媒管13、冷凝水管14、冷凝水管换热翅片15、冷凝水管支架16。室外防雨防风罩11设置于矩形新风管12的一端。冷凝水管支架16支撑冷凝水管14，在使用过程中可保护冷凝水管换热翅片15。As shown in FIG. 2 , the combinedfresh air pipe 1 includes an outdoor rainproof andwindproof cover 11 , a rectangularfresh air pipe 12 , arefrigerant pipe 13 , acondensed water pipe 14 ,heat exchange fins 15 of the condensed water pipe, and a condensedwater pipe bracket 16 . The outdoor rainproof andwindproof cover 11 is arranged on one end of the rectangularfresh air pipe 12 . The condensedwater pipe support 16 supports thecondensed water pipe 14, and can protect theheat exchange fins 15 of the condensed water pipe during use.

壁挂主机2的结构如图3所示，所述壁挂主机2包括主机回风口21、新风管通道22、主机机壳23、主机送风口24。The structure of the wall-mountedhost 2 is shown in FIG. 3 . The wall-mountedhost 2 includes a hostreturn air outlet 21 , a freshair duct channel 22 , ahost casing 23 , and ahost air outlet 24 .

请参阅图4，所述壁挂副机3包括副机回风口31、副机新风口32、副机第二新风口331、副机第二回风口332、副机送风口34；新风管通道32的一端连接矩形新风管12，另一端连接副机第二新风口331。所述副机第二新风口331设有第一新风风阀，副机第二回风口332设有第二新风风阀。Please refer to Fig. 4, described wall-mountedauxiliary machine 3 comprises auxiliary machineair return port 31, auxiliary machinefresh air port 32, auxiliary machine secondfresh air port 331, auxiliary machine secondair return port 332, auxiliary machineair supply port 34; One end of 32 is connected to the rectangularfresh air pipe 12, and the other end is connected to the secondfresh air port 331 of the auxiliary machine. The secondfresh air outlet 331 of the auxiliary machine is provided with a first fresh air damper, and the second freshair return port 332 of the auxiliary machine is provided with a second fresh air damper.

室内有新风需要时，如图1、7所示，室外新鲜空气经矩形新风管12和壁挂主机2的新风管通道22进入壁挂副机3风机吸入段的副机第二新风口331，室内空气经副机回风口31与室外新风混合后经副机送风口34送出，引入新风营造良好的室内空气品质。当可以利用室外空气进行自然通风时，室外机停止工作，停止输送冷媒，此时壁挂副机3单独工作，由副机送风口34完成室内通风。风量大小可根据房间具体情况确定，风量调整手段为调节副机第二新风口331、副机第二回风口332内的新风风阀的开度和主机风机功率。When fresh air is needed indoors, as shown in Figures 1 and 7, the outdoor fresh air enters the secondaryfresh air outlet 331 of theauxiliary machine 3 fan suction section of the wall-mountedauxiliary machine 3 through the rectangularfresh air duct 12 and the freshair duct channel 22 of the wall-mountedmain unit 2, The indoor air is mixed with the outdoor fresh air through theair return port 31 of the auxiliary machine and sent out through theair supply port 34 of the auxiliary machine, and the fresh air is introduced to create good indoor air quality. When the outdoor air can be utilized for natural ventilation, the outdoor unit stops working and stops transporting the refrigerant. At this time, the wall-mountedauxiliary machine 3 works alone, and theair supply port 34 of the auxiliary machine completes the indoor ventilation. The air volume can be determined according to the specific conditions of the room. The air volume adjustment means is to adjust the opening degree of the fresh air air valve in the secondfresh air port 331 of the auxiliary machine and the secondair return port 332 of the auxiliary machine and the power of the main engine fan.

在冬季模式下，如图5所示，壁挂副机3的副机送风口34气体出流方向向上，气流经副机送风口34吹出后贴附天花板，给房间上部积聚热量以扰动促成室内热分布均匀。在该模式下，室外机不再向壁挂副机2提供热量，副机送风口34出流气流为通过副机回风口31和副机第二回风口332直接混合后获得的冷气流。如果此时室内需要新风如图7所示，则打开副机第二新风口331的第一新风风阀，改善室内空气品质。In the winter mode, as shown in Figure 5, the air flow direction of theair outlet 34 of theauxiliary machine 3 of the wall-mounted auxiliary machine is upward. evenly distributed. In this mode, the outdoor unit no longer provides heat to the wall-mountedauxiliary unit 2, and the air flow out of theair supply port 34 of the auxiliary unit is the cold air obtained by directly mixing through theair return port 31 of the auxiliary unit and the secondair return port 332 of the auxiliary unit. If at this moment indoor needs fresh air as shown in Figure 7, then open the first fresh air damper of the secondfresh air outlet 331 of auxiliary machine, improve indoor air quality.

夏季模式下，如图6所示，室外新风被送入矩形新风管12内，此时壁挂主机产生的冷凝水经过冷凝水管14与新风逆流流动，新风通过与冷凝水管14上的冷凝水管换热翅片15进行换热，将冷凝水冷量传递给空气，完成热交换以节约能源。初步冷却新风经壁挂副机2送入室内。由于有冷凝水管换热翅片15的存在，在使用过程中为保护冷凝水管换热翅片15，特设置冷凝水管支架16。当房间狭长时，普通壁挂空调器不能解决长距离输送冷气，如图6所示，该壁挂副机风口34可以改变左右出流角将冷气送到较远空间。In summer mode, as shown in Figure 6, the outdoor fresh air is sent into the rectangularfresh air pipe 12. At this time, the condensed water generated by the wall-mounted host flows countercurrently with the fresh air through thecondensed water pipe 14, and the fresh air is exchanged with the condensed water pipe on thecondensed water pipe 14. Theheat fins 15 perform heat exchange, transfer the cooling capacity of the condensed water to the air, and complete the heat exchange to save energy. The preliminary cooling fresh air is sent into the room through the wall-mountedauxiliary machine 2. Due to the existence of theheat exchange fins 15 of the condensed water pipes, in order to protect theheat exchange fins 15 of the condensed water pipes during use, a condensedwater pipe support 16 is specially provided. When the room is narrow and long, ordinary wall-mounted air conditioners cannot solve the long-distance delivery of cold air. As shown in Figure 6, theair outlet 34 of the wall-mounted auxiliary unit can change the left and right outflow angles to send cold air to a far space.

综上所述，本发明的优点在于灵活配置了一个独立的壁挂空调副机，该空调副机具有引入新风功能和营造良好气流组织功能，同时冷凝水预冷新风和全新风通风又节省了能量。To sum up, the advantage of the present invention lies in the flexible configuration of an independent wall-mounted air conditioner auxiliary unit, which has the function of introducing fresh air and creating a good airflow organization, and at the same time, the condensed water pre-cools the fresh air and fresh air ventilation saves energy .
