controlling the air pipe machine to be in a refrigerating or heating mode;

detecting indoor environment temperature and compressor frequency;

the opening and closing state of the cover 120 and the frequency of the compressor are controlled according to the indoor environment temperature and/or the frequency of the compressor.

According to the control method of the air duct machine, the opening and closing state of the cover body 120 and the frequency of the compressor are controlled according to the indoor environment temperature and/or the frequency of the compressor, so that the air quantity input into the heat exchange device 200 is controlled, and the energy consumption is saved and the running noise is reduced.

Specifically, referring to fig. 1 and 2, the step of controlling the opening/closing state of the cover 120 according to the indoor environment temperature and/or the compressor frequency includes:

acquiring a temperature difference value T between an indoor environment temperature T1 and a preset temperature T0;

acquiring a frequency difference F between the frequency F1 of the compressor and a preset frequency F;

when T.ltoreq.T2 or F.ltoreq.F2, the control cover 120 is closed.

It should be noted that T1 and T2 are temperature difference set values, and F1 and F2 are frequency difference set values. Through the steps, the air quantity can be more accurately regulated according to the actual air quantity, so that the comfort is improved and the energy consumption is reduced.
