Heat storage control method for air conditioner

Abstract

The invention relates to the technical field of air conditioning, in particular to an air conditioning heat storage control method. The invention aims to solve the problems of short compressor life and large coil temperature fluctuations existing in the existing preheating scheme. For this purpose, the air conditioner of the present invention includes a compressor, a throttling element, an outdoor heat exchanger, an outdoor fan, an indoor heat exchanger and an indoor fan, the outdoor fan is an AC fan, and the heat storage control method includes: controlling the compressor to first Heat storage frequency operation; control the operation of the outdoor fan at the same time, before or after the compressor starts running; detect the coil temperature of the indoor heat exchanger during the operation of the compressor at the first heat storage frequency; judge the coil temperature and the magnitude of the first preset temperature; based on the judgment result, selectively adjust the on / off of the outdoor fan and / or the operating frequency of the compressor. The heat storage control method of the present invention can increase the service life of the compressor, reduce the fluctuation of the coil temperature during the heat storage process of the air conditioner, and improve user experience.

Description

Air conditioning heat storage control method technical field The present invention relates to air conditioning technical field, be specifically related to a kind of air conditioning heat storage control method. Background technique When starting the air conditioner in cold winter, because the indoor and outdoor temperatures are lower, the wind blowing out after starting the air conditioner is cold. Wind, which seriously affects the user experience, for this reason, the existing air conditioners are equipped with an anti-cold wind mode. When the anti-cold wind mode is activated, the By controlling the compressor and outdoor fan to start to store heat, and after the temperature rises, control the operation of the indoor fan to avoid When the boot is turned on, the cold air is blown out. However, in practical applications, within a few minutes after turning on the air conditioner, the air conditioner runs against cold air due to the Mode and the waiting time is long, ...
