Referring to fig. 3, a solid large arrow indicates a flow path of indoor clean air, and in the cooling/heating mode, the indoor clean air circulates into the room through the indoor circulating air inlet 130, the internal circulating air duct, and the indoor air outlet 140;
the indoor air outlet 140 is opposite to the indoor circulating air inlet 130, and the internal circulating air duct is substantially a straight line connecting the indoor air outlet 140 and the indoor circulating air inlet 130.

Based on the embodiment of the present disclosure, the heat exchanger 21 is disposed in the indoor air outlet chamber 14, and the blower 22 is disposed in the clean air inlet chamber 13 and connected to the partition plate between the clean air inlet chamber 13 and the indoor air outlet chamber 14, i.e. the heat exchanger 21 and the blower 22 are separated in two different chambers, so that the effect of preventing the blower 22 from generating condensation is better.
Particularly, air conditioner submodule 2 sets up two forced draught blowers 22 side by side on the baffle, satisfies amount of wind-force requirement on the one hand, and on the other hand can be so that the right-hand member of heat exchanger 21 is sent to by right side forced draught blower 22 to the new trend under the mixed wind mode, effectively distributes the heat transfer ability under the mixed wind mode.
In some embodiments of the present disclosure, the heat exchanger 21 is a direct-exhaust heat exchanger 21, and is obliquely disposed in the indoor air outlet chamber 14, for example, the heat exchanger 21 is obliquely disposed at 45 °, so that the heat exchange area can be maximized, the direct-exhaust heat exchanger 21 is not bent, the eddy current loss is reduced, and the heat exchange capability of the whole machine is improved; the wind speed on the surface of the direct-discharge heat exchanger 21 is uniform under the air duct layout, no low-energy section exists, and the airflow can effectively utilize the rectification effect of the heat exchanger 21 when being blown to the heat exchanger 21 through the preset interval by the blower 22, so that the airflow uniformity of the indoor air outlet 140 is improved, and the noise of the whole machine is improved.
Based on the embodiment of the present disclosure, the air-conditioning submodule 2 further has a purification processing function, specifically, includes a purification filter screen 23 and an electrostatic dust collection module 24, the purification filter screen 23 is disposed at the upstream of the blower 22, specifically, at the indoor circulating air inlet 130, and is used for primarily filtering the indoor clean air entering the casing 1; the electrostatic dust collection module 24 is disposed at the downstream of the heat exchanger 21, specifically between the heat exchanger 21 and the indoor air outlet 140, and is used for filtering indoor clean air and fresh air discharged to the outside of the housing 1.
