Multi-split air conditioner, control method of multi-split air conditioner, air conditioner control device and readable storage medium

Abstract

The invention discloses a multi-split air conditioner control method, which comprises the steps that: an ambient temperature of an environment where a target indoor unit is located is obtained; the ambient temperature is detected by a temperature sensor in the target indoor unit, wherein the target indoor unit is an indoor unit which operates in a heating mode in at least two indoor units; when the ambient temperature is higher than or equal to a target temperature for heating operation of the indoor unit, an indoor fan in the target indoor unit is controlled to stop; a temperature value detected by the temperature sensor is monitored; and when an indoor heat exchanger in the target indoor unit is in a heat release state and the temperature value is lower than or equal to a set temperature, the indoor fan in the target indoor unit is controlled to start up, wherein the set temperature is higher than the ambient temperature. The invention further discloses an air conditioner control device, the multi-split air conditioner and a readable storage medium. According to the method, the indoor unit can be started in time after the indoor unit reaches the temperature and shuts down in the heating process of the multi-split air conditioner, it is guaranteed that the environment temperature can be maintained at the user comfort temperature, and the heat comfort requirement of a user is met.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a multi-connected air conditioner control method, an air conditioner control device, an air conditioner and a readable storage medium. Background technique [0002] In multi-split air conditioners, multiple indoor units are generally connected to one compressor. When any indoor unit has a heat exchange requirement, the compressor starts to provide the required cooling or heat for the indoor unit. Among them, during the indoor heat exchange process, the temperature sensor in the indoor unit detects the temperature of the environment where it is located. When the detected temperature reaches the set temperature, the indoor unit will stop running, stop supplying air to the environment where it is located, and detect the ambient temperature after the shutdown. If the temperature does not meet the set temperature, it will restart to maintain the ambient temperature. [0003]...

AI Technical Summary

Problems solved by technology

[0003] However, when the heating indoor unit reaches the temperature and shuts down, if other indoor units still require heat exchange, the compressor will remain on. In order to avoid refrigerant accumulation, high-temperature and high-pressure refrigerant will continue to flow into the heat exchanger of the shut down indoor unit. Continue to release heat, the released heat will cause the data detected by the sensor used to detect the ambient temperature in the shut down indoor unit to be higher than the actual temperature of the environment, and the indoor unit cannot be started in time after the ambient temperature drops, affecting user comfort
