Abstract

The invention discloses a heat dissipation control method and device of an electric control box and an air conditioner, relates to the technical field of air conditioning equipment, and aims at solving the technical problem of reducing heat dissipation power consumption of the electric control box. The heat dissipation control method of the electric control box comprises the following steps of: acquiring a detection temperature of a temperature sensor in the electric control box; according to the detection temperature of the temperature sensor, determining an operation wind speed of a cooling fan corresponding to a target device in the electric control box; and driving the cooling fan to cool the target device according to the operation wind speed of the cooling fan. According to the heat dissipation control method and device of the electric control box and the air conditioner, the corresponding operation wind speed of the heat dissipation fan is determined based on different detection temperatures, and therefore the heat dissipation power consumption of the electric control box is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a heat dissipation control method and device for an electric control box and an air conditioner. Background technique [0002] Control components such as an electric control board are usually installed in the electric control box of the air conditioner to control the operation of the compressor in the air conditioner. With the rapid development of air-conditioning technology, air-conditioning functions and control methods are gradually diversified. Correspondingly, the heat generated by the electric control box of the air-conditioner is gradually increasing. However, the operating power of the heat dissipation fan of the electric control box of the existing air conditioner is usually the same, and correspondingly, the operating wind speed of the heat dissipation fan is constant, resulting in excessive heat dissipation power consumption of the electric control box. Cont...
