[0025] The purifier body 100 utilizes a metal frame, which is partitioned by multiple partitions 130 to form a fresh air chamber 120, a supply air chamber 140, a return air chamber 160, and an exhaust air chamber 180. The bypass air duct 150 extends at least partially along the length of the purifier body 100 and is longer than the combined length of the return air chamber 160 and the heat pump core 200.
[0026] The heat pump core 200 is also located between the return air chamber 160 and the exhaust air chamber 180 . The heat pump core 200 extends along the width direction of the purification body 100 and has a hexagonal cross-section for heat exchange.
[0027] The central direction of the fresh air valve 300 is parallel to the length direction of the purification body 100 and perpendicular to the central direction of the bypass valve 320 , wherein the fresh air valve 300 and the bypass valve 320 are located on different sides of the return air chamber 160 .

[0031] The main controller 600 in this embodiment has the following two working modes:
[0032] 1. Fresh air mode (bypass valve 320 closed and fresh air valve 300 open):
[0033] The supply fan 520 starts working, and sends outdoor air into the room through the fresh air inlet 122. The outdoor air is first filtered by the fresh air filter 400, and then undergoes heat exchange through the heat pump core 200, and is finally sent into the room by the supply fan 520; then the exhaust fan 540 starts working, and discharges the indoor air to the outside through the return air inlet 162, wherein the indoor air passes through the fresh air valve 300 and is filtered by the fresh air filter 400, and then undergoes heat exchange through the heat pump core 200, and is then discharged to the outside by the exhaust fan 540.

[0034] 2. Bypass mode (bypass valve 320 is open and fresh air valve 300 is closed):
[0035] The supply air fan 520 starts working, and sends outdoor air into the room through the fresh air inlet 122. The outdoor air is first filtered by the fresh air filter 400, then passes through the heat pump core 200, and is finally sent into the room by the supply air fan 520; then the exhaust air fan 540 starts working, and discharges the indoor air to the outside through the return air inlet 162. The indoor air is directly discharged to the outside by the exhaust air fan 540 through the bypass valve 320, and the heat pump core 200 does not work in the bypass mode.
[0036] The utility model has the advantages that: the utility model has an independent bypass air duct, and air flow backflow can be achieved through the bypass air duct, thereby maintaining indoor temperature and reducing energy consumption.
[0037] The above are only preferred implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with this technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
