Control method of air conditioning system, air conditioning system and computer storage medium

Abstract

The invention provides a control method of an air conditioning system, the air conditioning system and a computer storage medium. The control method of the air conditioning system comprises the following steps that based on the air conditioning system, a heating mode is operated, and system operation parameters in a preset oil return period, accumulated operation time corresponding to the system operation parameters and outdoor environment temperature are obtained; and based on the end of the preset oil return period, and under the condition that the system operation parameters, the accumulated operation time and the outdoor environment temperature all meet the heating oil return condition, the air conditioning system is controlled to return oil in the heating mode. According to the control method of the air conditioning system, the operation parameters in the oil return period of the air conditioning system, the accumulated operation time under the operation parameters and the outdoorenvironment temperature are obtained, and when the parameters meet the heating oil return condition, the air conditioning system is controlled to carry out heating oil return, so that the problem that the indoor temperature is reduced due to the fact that an air conditioning system compressor must be switched into a refrigeration mode during oil return in the prior art is solved, and the user experience is improved.

Description

technical field

[0001] The present invention relates to the technical field of air-conditioning equipment, and in particular, relates to a method for controlling an air-conditioning system, an air-conditioning system, and a computer storage medium. Background technique

[0002] In related technologies, when the compressor of the air conditioning system is running, the lubricating oil is discharged together with the refrigerant, and the discharged lubricating oil needs to be returned to the compressor at an appropriate time to provide lubrication for the compressor. , When the compressor needs to return oil, the system needs to switch to the cooling mode, and the lubricating oil will be brought back to the compressor by flowing through the liquid refrigerant, but switching to the cooling state will cause the indoor temperature to drop, which will affect the user experience. Contents of the invention

[0003] The present invention aims to solve at least one of the technical ...
