Therefore, the air conditioning system can operate the reheat dehumidification mode in the transition season. As shown in Figure 1, the system cycle is as follows. Specifically, the refrigerant side cycle is: the second four-way reversing valve is energized, the first four-way reversing valve When the power is turned off, the first control valve 120 is opened and the first throttling device 170 is closed. The high-temperature and high-pressure refrigerant is discharged from the exhaust port assembly 11 and divided into two paths. The fresh air cooled and dehumidified by the heat exchanger 20 is reheated to increase the supply air temperature, and after the heat exchange is completed, the fourth throttling device 240 is throttled and reduced in pressure; the other refrigerant enters the third heat exchanger 40 for heat exchange, After the heat is completed, the second throttling device 220 is throttled and depressurized, and then enters the flasher 90, the gaseous refrigerant emitted by the flasher enters the third suction port 123 of the compressor, and the liquid saturated refrigerant separated by the flasher enters the first.

After the refrigerant entering the compressor is compressed in the respective compression cylinders, the exhaust gas is mixed and discharged to complete the entire cycle.

具体地，在空调***运行再热除湿模式时，空气侧循环为：第三风机260将室内浑浊的空气吸入排风风道，室内排风与第五换热器130进行换热，回收室内空气冷量(即第五换热器130相当于一个显热回收装置)。第二风机250将室外高湿、新鲜的空气吸入新风风道，室外新风依次经过第一换热器20、第二换热器30。第一换热器20对室外高湿空气进行降温除湿，第二换热器30对被降温除湿的新风进行升温，提升室内温度的同时提高室内空气质量。空调***不断的循环往复上述过程，用室外新风去置换室内浑浊空气，从而保证室内空气的新鲜，干爽，舒适，提高室内空气质量，提高生活品质。Specifically, when the air-conditioning system operates in the reheat dehumidification mode, the air-side circulation is as follows: the third fan 260 sucks the indoor turbid air into the exhaust air duct, and the indoor exhaust air exchanges heat with the fifth heat exchanger 130 to recover the indoor air. cooling capacity (ie, the fifth heat exchanger 130 is equivalent to a sensible heat recovery device). The second fan 250 sucks the outdoor high-humidity and fresh air into the fresh air duct, and the outdoor fresh air passes through the first heat exchanger 20 and the second heat exchanger 30 in sequence. The first heat exchanger 20 cools and dehumidifies the outdoor high-humidity air, and the second heat exchanger 30 heats the fresh air that has been cooled and dehumidified, so as to increase the indoor temperature and improve the indoor air quality. The air-conditioning system continuously reciprocates the above process, and replaces the indoor turbid air with outdoor fresh air, thereby ensuring the freshness, dryness and comfort of the indoor air, improving the indoor air quality and improving the quality of life.

具体地，在空调***运行再热除湿模式时，通过第二四通换向阀的换向实现制冷模式与再热除湿模式的切换。该模式不仅采用并行压缩技术、凝露水过冷降温模块、显热回收技术等提高***的能效，而且对空气的再热处理能够提升新风的舒适度。此时第一换热器20作为蒸发器，而第二换热器30作为低温冷凝器，这样设置一方面可以在一定程度上降低***的冷凝温度，增大***过冷度，从而进一步的提升***能效。另一方面，由于在湿热地区与过度季节除湿时，蒸发器的温度常常较低才能达到除湿的目的，从而使得被处理的空气温度较低，直接吹于人体表面时会使人感觉不适，而将第二换热器30当作一个低温冷凝器后，对除湿后的空气进行加热，从而满足空气舒适度的要求，具有独特的性能优势。Specifically, when the air-conditioning system operates in the reheating and dehumidifying mode, the switching between the cooling mode and the reheating and dehumidifying mode is realized through the reversal of the second four-way reversing valve. This mode not only uses parallel compression technology, condensation water cooling module, sensible heat recovery technology, etc. to improve the energy efficiency of the system, but also reheat treatment of the air can improve the comfort of the fresh air. At this time, the first heat exchanger 20 is used as an evaporator, and the second heat exchanger 30 is used as a low-temperature condenser. On the one hand, this setting can reduce the condensation temperature of the system to a certain extent, increase the degree of subcooling of the system, and further improve the System energy efficiency. On the other hand, when dehumidifying in hot and humid areas and excessive seasons, the temperature of the evaporator is often lower to achieve the purpose of dehumidification, so that the temperature of the air to be treated is lower, and it will make people feel uncomfortable when it is directly blown on the surface of the human body.

The high-temperature and high-pressure refrigerant discharged from the compressor is divided into two paths through the first exhaust port 16, and enters the third heat exchanger 40 and the fifth heat exchanger through the first four-way reversing valve and the second four-way reversing valve respectively. 130 (wherein, what exchanges heat with the third heat exchanger 40 is outdoor ambient air, and what exchanges heat with the fifth heat exchanger 130 is indoor exhaust air). The refrigerants from the third heat exchanger 40 and the fifth heat exchanger 130 are throttled and depressurized through the second throttling device 220 and the first throttling device 170 respectively, and the two refrigerants after the throttling and decompression are mixed and mixed. The last refrigerant enters the flasher 90, and the saturated gaseous refrigerant separated by the flasher 90 is sucked into the third suction port 123 of the compressor through the supplementary gas pipeline 310; the liquid saturated refrigerant separated by the flasher 90 enters the The fourth heat exchanger 80 exchanges heat with the low-temperature condensate water of the air conditioner, and is further subcooled, and the condensate water after the heat exchange is completed is discharged outdoors with the pipeline; the subcooled liquid cooling from the fourth heat exchanger 80 is cooled. The refrigerant passes through the third throttling device 230 and the fourth throttling device 240 to be throttled and reduced in pressure, respectively, and the throttled low-pressure two-phase refrigerant enters the first heat exchanger 20 and the second heat exchanger 30 respectively for heat exchange, from The gaseous refrigerant from the first heat exchanger 20 enters the first suction port 121 of the compressor 10 through the third valve port 53 and the fourth valve port 54 of the first four-way reversing valve, and flows from the second heat exchanger. The gaseous refrigerant coming out of 30 enters the second suction port 122 of the compressor through the seventh valve port 63 and the eighth valve port 64 of the second four-way reversing valve; the refrigerant entering the compressor is in the respective compression cylinders After the compression is complete, the exhaust gases are mixed and discharged to complete the cycle.

具体地，在空调***运行制冷模式时，空气侧循环为：第三风机260将室内低温、浑浊的空气吸入排风风道内，用室内的排风给第五换热器130散热，回收室内空气的冷量(第五换热器130相当于一个显热回收装置)。第二风机250将室外高温、新鲜的空气吸入新风风道，室外新风依次经过第一换热器20、第二换热器30，被降温、除湿的新鲜空气被送入室内。空调***不断的循环往复上述过程，用室外新风去置换室内浑浊空气，从而保证室内空气的新鲜，干爽，舒适，提高室内空气质量，提高生活品质。Specifically, when the air-conditioning system is operating in the cooling mode, the air-side circulation is as follows: the third fan 260 sucks the indoor low-temperature and turbid air into the exhaust air duct, uses the indoor exhaust air to dissipate heat to the fifth heat exchanger 130, and recovers the indoor air (the fifth heat exchanger 130 is equivalent to a sensible heat recovery device). The second fan 250 sucks the outdoor high temperature and fresh air into the fresh air duct, and the outdoor fresh air passes through the first heat exchanger 20 and the second heat exchanger 30 in sequence, and the cooled and dehumidified fresh air is sent indoors. The air-conditioning system continuously reciprocates the above process, and replaces the indoor turbid air with outdoor fresh air, thereby ensuring the freshness, dryness and comfort of the indoor air, improving the indoor air quality and improving the quality of life.

The high-temperature evaporator is mainly responsible for the sensible heat load, and the low-temperature evaporator is mainly responsible for the latent heat load. , The outdoor fresh air is subjected to cascade cooling and dehumidification treatment, the dry and wet are distinct, and the heat exchange temperature difference is reduced, the irreversible loss of the heat exchange process is reduced, and the energy efficiency of the system is improved. The fifth heat exchanger 130 is used to recover the cooling capacity in the indoor exhaust air, and is equivalent to a sensible heat recovery device. Since the gaseous refrigerant enters the compressor in the form of supplementary air through the flasher, the inlet enthalpy value of the refrigerant entering the first heat exchanger 20 and the second heat exchanger 30 (evaporator) is reduced, and condensation is used at the same time. The liquid refrigerant separated by the water subcooling flasher further subcools the refrigerant, further reduces the inlet enthalpy of the evaporator, and increases the cooling capacity per unit mass of the refrigerant, thereby achieving the purpose of improving the energy efficiency of the air conditioning system.
