the air temperature sensor 310 and the air quality sensor 320 monitor the temperature of the air entering the heat exchanger 200 and the air quality in real time, and the controller 420 starts the heat exchanger 200 to exchange heat (i.e. raise or lower the temperature) of the air when the air temperature does not meet the preset temperature threshold, so that the air temperature is comfortable for people; in the case that the air quality does not meet the preset quality threshold, the controller 420 starts the ventilation and dust removal device 100 to perform fresh air treatment on the air so as to meet the indoor standard of air intake.

The embodiment has the advantage that the air temperature sensor 310 and the air quality sensor 320 are utilized to monitor the temperature and the air quality of the air entering the heat exchanger 200 in real time, so that the opening or closing of the heat exchanger 200 and the ventilation and dust removal device 100 can be effectively controlled, and the energy saving and the efficiency improvement are facilitated.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples merely represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the utility model. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
