Embodiment Construction

[0031] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0032] When the air conditioner is in the heating state, due to the low ambient temperature and high humidity, the evaporator of the air conditioner is prone to frost, so the power of the air conditioner fan will increase. The embodiment of the present invention determines the evaporation by judging the change of the tube temperature of the air conditioner evaporator. The frosting condition of the air conditioner, thereby controlling the speed of the air conditioner fan.

Abstract

The embodiment of the invention provides a control method and device for the air conditioner fan rotation speed and an air conditioner and belongs to the technical field of air conditioners. The control method and device for the air conditioner fan rotation speed and the air conditioner solve the problem that the load of a fan is excessive due to the serious frosting. The control method for the air conditioner fan rotation speed comprises the steps that the pipe temperature of an air conditioner evaporator is measured at the preset interval time; and the air conditioner fan rotation speed is controlled according to the pipe temperature of the air conditioner evaporator. The control method and device and the air conditioner are suitable for the process of reducing the air conditioner frosting.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for controlling the speed of an air conditioner fan and an air conditioner. Background technique [0002] In the case of low ambient temperature and high humidity in winter, the evaporator of the air conditioner is prone to frost. Once frost occurs, the fan power will increase and the fan load will increase. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a method, device and air conditioner for controlling the speed of an air conditioner fan. The method, device and air conditioner for controlling the speed of an air conditioner fan determine the frosting condition of the evaporator by judging the tube temperature of the evaporator, thereby avoiding the Due to the problem of heavy fan load due to severe frost, the effective protection of the fan has been realized. [0004] In order to achieve...
