Abstract

The invention discloses a control method of an air conditioner and the air conditioner, relates to the technical field of air conditioners, and solves the problems that the cost is high, and the stability of the air conditioner is poor when condensing pressure of the multi-connected split air conditioner is reduced. According to the specific scheme, when a heating mode is operated, an operation frequency of a compressor is determined according to the current outdoor environment temperature; the compressor is controlled to operate according to the operation frequency, and an outdoor fan is controlled to operate at a preset rotating speed; and after the compressor runs for a preset time period, the rotating speed of the outdoor fan is adjusted according to the temperature of an indoor coil.The method is used in the process of reducing the condensing pressure of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and the air conditioner. Background technique [0002] At present, there are more and more applications of one-to-many air conditioners. In spring and autumn, when the one-to-multi-air conditioner is running in the heating mode, the condensing pressure is relatively high due to the high indoor and outdoor ambient temperatures. When the condensing pressure exceeds the preset value, the air conditioner will be controlled to stop, which affects the normal use by the user. [0003] In the related art, in order to solve the problem of shutting down the air conditioner due to too high condensing pressure, a solenoid valve can be added between the suction pipe and the outlet pipe of the compressor, that is, between the high pressure pipe and the low pressure pipe. By controlling the opening and closing of the electromagnetic valve, the purpos...
