Control method of air conditioner and air conditioner

Abstract

The invention relates to the technical field of air conditioning, in particular to a control method of an air conditioner and the air conditioner. The problem that a condenser is easy to block in a sand and dust weather is solved; the air conditioner comprises a compressor, a condenser, a throttling device and an evaporator which are connected in sequence; the condenser is provided with an external fan, and the evaporator is provided with an internal fan; the air conditioner further comprises a pressure reducing branch, the two ends of the pressure reducing branch respectively communicate witha liquid outlet of the throttling device and an air suction port of the compressor, and a valve mechanism is arranged on the pressure reduction branch; and the control method comprises the followingsteps that an operation mode of the air conditioner is acquired; when an operation mode is a sand and dust mode, the external fan is controlled to reduce the speed, and the valve mechanism is controlled to be opened at the same time, before or after the external fan begins to decrease the speed. Through the control mode, under the premises that the running effect of the air conditioner is guaranteed, the control method of the air conditioner can reduce the suction of the wind and sand of an outdoor unit, and the service life of the air conditioner is prolonged.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner control method and the air conditioner. Background technique [0002] At present, air conditioners are widely used and have gradually become an indispensable household appliance for people in summer. But for the area of ​​some special environments, there are still some problems in the operation of the air conditioner. [0003] For example, for the Middle East and other regions, due to the high temperature all year round, the air conditioner needs to run continuously for a long time. The accumulation of sand and dust will cause blockage of the condenser, which will seriously affect the operation effect and service life of the product. [0004] Correspondingly, there is a need in the art for a new control method for an air conditioner to solve the above problems. Contents of the invention [0005] In order to solve the above-mentioned problems in th...
