Air conditioner refrigeration and heating control method and air conditioner

Abstract

The invention discloses an air conditioner refrigeration and heating control method and an air conditioner, wherein the method comprises the steps: a controller of the air conditioner detects the temperature of an outer ring after receiving a starting instruction, and enters a refrigeration and heating starting mode after the temperature of the outer ring meets a refrigeration and heating startingcondition; a compressor is controlled to be started at a preset target frequency and the starting opening degree, corresponding to the target frequency, of an electronic expansion valve, and after starting is conducted for preset time, the frequency with the smaller numerical value in the outer ring temperature frequency and the indoor windshield frequency limiting frequency is compared with thetarget frequency; if the frequency is smaller than the target frequency, the compressor is controlled to operate at the target frequency and the corresponding starting opening degree; otherwise, the compressor is controlled to operate at the frequency with the smaller numerical value in the outer ring temperature frequency and the indoor windshield frequency limiting frequency and the starting opening degree corresponding to the smaller frequency. Under the condition that the running reliability and low-noise running of the air conditioner are guaranteed, rapid refrigerating and heating are achieved, and the refrigerating and heating effects are guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner cooling and heating control method and the air conditioner. Background technique [0002] In the prior art, the rapid cooling and heating control method of the air conditioner mainly realizes one-button rapid cooling and heating control through the rapid cooling and heating button on the remote control. This control method is to control the air conditioner to enter rapid cooling through the remote control. In the heating mode, after entering the fast cooling and heating mode, the startup mode set in the program is completely fixed, and the fast cooling and heating effect is achieved according to the fast cooling temperature, fast heating temperature, large air volume, and high air volume. [0003] However, for different air conditioner control systems, the rapid cooling and heating effect can be achieved only from high air volume and high air volume, a...
