Method and device for controlling air return of air conditioner, air conditioner and storage medium

Abstract

The invention provides a method and device for controlling air return of an air conditioner, the air conditioner and a storage medium. The method comprises the steps that the air conditioner air return opening temperature and the indoor environment temperature are acquired; and according to the air conditioner air return opening temperature and the indoor environment temperature, whether the air conditioner operates in an air return short circuit preventing mode or not is determined. According to the method and device for controlling air return of the air conditioner, the air conditioner and the storage medium, in the use process of the air conditioner, the air conditioner air return opening temperature and the indoor environment temperature are acquired in real time, the current operationstate of the air conditioner can be acquired, and whether the air conditioner operates in the air return short circuit preventing mode or not is determined according to the air conditioner air returnopening temperature and the indoor environment temperature; and the air return short circuit phenomenon of the air conditioner, especially a ceiling unit can be effectively avoided, the operation effect and reliability of the air conditioner are guaranteed, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner return air control method and device, an air conditioner and a storage medium. Background technique [0002] As people's requirements for air conditioning systems are increasing day by day, traditional air conditioners can no longer meet market demand, especially for housing structures with different length and width ratios. The current air conditioners on the market cannot fully meet the needs of users in different housing structures. . In order to meet the needs of users for appearance, air conditioner manufacturers have designed ceiling units embedded in the roof of the house, and the distance between the air outlet and return air outlet of the ceiling unit is relatively close, and it is very likely that the air will return to the return air outlet after a short flow path. situation, resulting in a short circuit of the return air.

Problems solved by technology

[0002] As people's requirements for air conditioning systems are increasing day by day, traditional air conditioners can no longer meet market demand, especially for housing structures with different length and width ratios. The current air conditioners on the market cannot fully meet the needs of users in different housing structures.

In order to meet the needs of users for appearance, air conditioner manufacturers have designed ceiling units embedded in the roof of the house, and the distance between the air outlet and return air outlet of the ceiling unit is relatively close, and it is very likely that the air will return to the return air outlet after a short flow path. situation, resulting in a short circuit of the return air

[0003] In the actual use of the air conditioner, if there is often a short circuit of the return air, the outlet air will not be able to fully exchange heat with the air in the room, resulting in uneven temperature throughout the room, poor use of the unit, and a waste of air conditioning system resources.

If the unit is in the cooling mode, the return air temperature is low and the evaporation temperature is low, which may cause the unit to return liquid; Protection phenomenon, affecting the reliability of unit operation
