The exhaust energy recovery device is used for recovering the energy of exhaust air, and after the exhaust air exchanges heat with the refrigerant in the second heat exchange tube 3, the refrigerant enters the first heat exchange tube 1 with the energy exchanged with the exhaust air to exchange heat with fresh air.
Two ends of the auxiliary heat exchange pipe 2 are respectively connected with the auxiliary cold and heat source unit 12, thereby forming an auxiliary cold and heat source compensation device for cold and heat source compensation when the exhaust air is recovered and the heat exchange is insufficient. When the recovered exhaust energy can not meet the heat exchange treatment requirement of fresh air, the auxiliary cold and heat source compensation device is started to supplement the cold and heat source.
Preferably, the first filter 8, the fresh air motor 7, the first heat exchange tube 1 and the auxiliary heat exchange tube 2 are sequentially arranged in the fresh air case 6 at intervals along the flow direction of fresh air. In addition, the second filter 11, the second heat exchange pipe 3 and the exhaust motor 10 are sequentially arranged in the exhaust fan box 9 at intervals along the exhaust flow direction.
Preferably, the four-way reversing valve 4 and the compressor 5 are integrally installed in the exhaust fan box 9, and the auxiliary cold and heat source unit 12 is separately installed outside the fresh air unit a and the exhaust fan unit B.
Preferably, the first filter 8 and the second filter 11 are equipped with pressure difference monitors for monitoring the pressure difference between both sides of the filters and with alarms to remind the replacement of the filters, so as to ensure the cleanliness of the air in the rooms of the building and reduce the pollution of the exhaust air to the outdoor air.
During specific implementation, the temperature sensor is arranged for monitoring the temperature of fresh air, and the auxiliary cold and heat source compensation device is started as required to perform cold and heat source compensation. When the recovery of airing exhaust is enough to carry out heat exchange, the auxiliary cold and heat source compensation device does not need to be started, and when the recovery of airing exhaust is not enough to carry out heat exchange, the auxiliary cold and heat source compensation device only needs to be started. The energy efficient utilization can be ensured, and the temperature of the fresh air can be kept constant.
