The heat exchanger assembly 300 includes an evaporator and a condenser, the evaporator is an important component of four major components for refrigeration, and the low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, so as to absorb heat in a vaporized manner, thereby achieving the refrigeration effect. The condenser is capable of converting a gas or vapor into a liquid to transfer heat from the tubes to the air adjacent the tubes in a rapid manner. The condenser operation is exothermic and therefore the condenser temperature is high.

The air conditioner 10 has three modes, i.e., a cooling mode, a heating mode, and an air blowing mode.

When the air conditioner 10 is in the cooling mode, the first heat exchanger 310 functions as an evaporator, the second heat exchanger 320 functions as a condenser, and the air conditioner 10 delivers cool air into the room. When the first fan 210 works, outdoor fresh air is introduced to the indoor cavity 110 through the fresh air duct 900, and then the cold air is blown out from the fresh air outlet 141 after heat exchange is performed through the evaporator. Meanwhile, since the second heat exchanger 320 emits heat as a condenser, the condenser temperature is high and higher than that of the outdoor environment, and thus heat dissipation to the condenser is required.

When the first fan 210 works, outdoor fresh air is introduced to the indoor cavity 110 through the fresh air duct 900, and then the warm air is blown out from the fresh air outlet 141 after heat exchange is performed through the condenser. Meanwhile, since the second heat exchanger 320 serves as an evaporator, the evaporator absorbs heat during operation, and the second fan 220 operates synchronously, so that outdoor air is introduced into the heat exchange cavity 122 through the heat exchange air inlet 162, exchanges heat with the evaporator through the part of outdoor air, and flows out of the heat exchange air outlet 151.

When the air conditioner 10 is in the air supply mode, the heat exchanger assembly 300 does not participate in the operation of the air conditioner 10. The first fan 210 located in the indoor cavity 110 works to introduce outdoor fresh air into the indoor cavity 110 through the fresh air duct 900, and then the first fan 210 blows the outdoor fresh air into the indoor space through the fresh air outlet 141 to realize indoor fresh air supply.
