Embodiment 1

[0038] The air conditioner in the prior art can divide the process from starting up in cooling mode until the system is stable into three stages:

[0039] The first stage: just after the compressor of the outdoor unit starts the compression process, the refrigerant in the evaporator of the indoor unit and the refrigerant in the connecting pipe (air pipe) of the indoor unit are sucked into the compressor, and at the same time, part of the compressed refrigerant is discharged from the exhaust port of the compressor. At this time, since the refrigerant in the evaporator of the indoor unit is sucked away by the compressor, the pressure of the refrigerant in the evaporator drops sharply, and the corresponding temperature of the refrigerant also drops accordingly. Evaporate and absorb part of the heat in the air, so that the temperature of the air outlet of the indoor unit begins to drop;

[0040] The second stage: As the compressor further sucks the refrigerant in the evaporator on...

Embodiment 2

[0080] The present invention provides an air conditioner control device, which implements any one of the above control methods, which includes:

[0081] The first control module 100, the first control module 100 is used to control the first electromagnetic two-way valve in the first refrigerant flow path to close when the air conditioner is in cooling mode and after the air conditioner receives a shutdown command;

[0082] The second control module 200, the second control module 200 is used to control the second electromagnetic two-way valve in the second refrigerant flow path to close after the compressor continues to run for a preset time t1;

[0083] The third control module 300, the third control module 300 is used to control the air conditioner to stop after the compressor stops running.

Embodiment 3

[0085] The present invention provides a computer-readable storage medium, where a computer program is stored in the computer-readable storage medium, and when the computer program is read and executed by a processor, any one of the above-mentioned methods can be realized.

Abstract

The invention provides a control method and control device of an air conditioner, a computer readable storage medium and the air conditioner. The control method of the air conditioner comprises the following steps: when the air conditioner is in a refrigeration mode, and after the air conditioner receives a shutdown command, a first electromagnetic two-way valve in a first refrigerant flow path iscontrolled to be closed, wherein the first refrigerant flow path includes a refrigerant outlet of an outdoor heat exchanger, the first electromagnetic two-way valve and a refrigerant inlet of an indoor heat exchanger which are sequentially connected; after a compressor is controlled to continuously operate for preset time t1, a second electromagnetic two-way valve in a second refrigerant flow path is controlled to be closed, wherein the second refrigerant flow path includes a refrigerant outlet of the indoor heat exchanger, the second electromagnetic two-way valve and a refrigerant inlet of the outdoor heat exchanger which are sequentially connected; and the air conditioner is controlled to stop after the compressor stops running.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular, to a control method, a control device, a computer-readable storage medium and an air conditioner. Background technique [0002] With the continuous popularization of air-conditioning products and the continuous development and progress of air-conditioning technology, users have higher and higher requirements for air-conditioning products. In the hot summer, users hope that after turning on the air conditioner, they can quickly get a lower and more comfortable air temperature. To achieve the effect of rapidly reducing the indoor temperature. In the air conditioner products in the prior art, after the refrigeration is turned on, the outlet air temperature of the indoor unit will drop first, then rebound to a certain extent, and then continue to drop. This situation will lead to poor user experience and cannot satisfy the user's expectations. The need for a rapid red...
