Description

technical field

[0001] The invention relates to an air-conditioning system, in particular to an air-conditioning system with cooling / heating, ventilation and dehumidification functions. Background technique

[0002] Generally, air conditioners cool or heat rooms such as residences and offices to provide a comfortable environment. figure 1 A schematic diagram of a cooling / heating system for related art air conditioning.

[0003] Such as figure 1 As shown, the refrigeration / heating system of the related art air conditioner is provided with a compressor 1 , a four-way valve 2 , an outdoor heat exchanger 3 , an indoor heat exchanger 4 and an expansion device 5 . There is an outdoor fan 3 a near the outdoor heat exchanger 3 , and an indoor fan 4 a near the indoor heat exchanger 4 . Under the control of the control unit, the cooling / heating system changes the flow direction of the refrigerant flowing through the indoor and outdoor heat exchangers by switching the four-way valve...
