Abstract

The invention provides an air conditioning unit and a surface treatment method of a heat exchanger of the air conditioning unit. The surface treatment method of the heat exchanger of the air conditioning unit comprises the following steps of acquiring an operation mode of the air conditioning unit; acquiring an surface image of an air side heat exchanger (1); carrying out analyzing treatment on the surface image of the air side heat exchanger (1); and entering a defrosting mode or a cleaning mode according to the analyzed surface image of the air side heat exchanger (1) and the operation modeof the air conditioning unit. According to the air conditioning unit and the surface treatment method of the heat exchanger of the air conditioning unit, surface unusual conditions of the heat exchanger can be treated in time, so that the heat exchange performance of the heat exchanger is ensured, and the working performance of the air conditioning unit is ensured.

Description

technical field

[0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning unit and a surface treatment method for a heat exchanger thereof. Background technique

[0002] When the air source heat pump unit is in heating operation, as the ambient temperature drops, it will face the problem of frosting on the surface of the evaporator. factors. In addition, the air source heat pump unit, as a kind of air-conditioning equipment that can provide both cooling and heating, is also used in a very wide range of regions, so the climate environment it faces is intricate and there are many frosting situations.

[0003] A general air source heat pump unit uses a temperature or pressure sensor to detect the evaporation temperature of the refrigerant as a judgment condition for defrosting entry and exit. This detection method is not a direct reflection of the frosting condition on the surface of the air-side heat exchanger, and there is ...
