The housing 100 is provided with a first air inlet 130 and a first air outlet 140 communicated with the first air duct 110, the housing 100 is further provided with a second air inlet 150 and a second air outlet 160 communicated with the second air duct 120, the first heat exchanger 300 is arranged in the first air duct 110, and two ends of the first heat exchanger 300 are connected with the housing 100 through fasteners, so that the first heat exchanger 300 can be reliably installed in the housing 100, the first heat exchanger 300 can be conveniently detached from the housing 100, and the maintainability of the first heat exchanger 300 can be improved. The first fan assembly 400 is disposed in the first air duct 110 to drive an air flow from the first air inlet 130 to the first air outlet 140.

The second heat exchanger 500 is arranged in the second air duct 120, one of the first heat exchanger 300 and the second heat exchanger 500 is a condenser, and the other of the first heat exchanger 300 and the second heat exchanger 500 is an evaporator, wherein when the first heat exchanger 300 is a condenser, the second heat exchanger 500 is an evaporator; when the first heat exchanger 300 is an evaporator, the second heat exchanger 500 is a condenser, and the refrigerant may be liquefied and release heat in the condenser, and evaporated and absorb heat in the evaporator, so that the refrigeration cycle of the air conditioner 1000 may be smoothly performed, and here, the first heat exchanger 300 is an evaporator, and the second heat exchanger 500 is a condenser, which is taken as an example for description, and is not to be construed as limiting the present application.

It can be understood that, when the air conditioner 1000 cools, the indoor hot air flow enters the first air duct 110 from the first air inlet 130, the hot air flow exchanges heat with the first heat exchanger 300 when passing through the first heat exchanger 300, and enters the first fan assembly 400 after becoming the cold air flow, and the first fan assembly 400 drives the cold air flow to the first air outlet 140, so that the cold air flow can flow from the first air outlet 140 to the indoor space to cool the indoor space; in order to enable the refrigeration cycle of the air conditioner 1000 to operate continuously, the indoor air flow further enters the second air duct 120 from the second air inlet 150, the air flow exchanges heat with the second heat exchanger 500 when passing through the second heat exchanger 500, and then enters the second fan assembly 600 after becoming a hot air flow, the second fan assembly 600 drives the hot air flow to the second air outlet 160, therefore, the hot air flow can flow to the indoor from the second air outlet 160, at this time, a heat pipe can be installed at the second air outlet 160 to guide the hot air flow out of the indoor, and the hot air flow flowing to the indoor can be left untreated, which is not particularly limited herein.
