Therefore, the first heat exchange air duct and the second heat exchange air duct can work independently and do not affect each other, and the heat exchange efficiency and the heat exchange effect of the mobile air conditioner 1 are improved conveniently. For example, the casing 100 has a first air inlet portion 130, and the first air inlet portion 130 is disposed at a rear end of the casing 100. The mobile air conditioner 1 has a second fan assembly 500, the second fan assembly 500 is disposed at the rear end of the second air duct cavity 122, the second fan assembly 500 can suck the outside air in the front-rear direction, and blow the air forward in the front-rear direction near the condenser, so that the condenser can perform heat exchange operation by using the blown air.
