Embodiment Construction

[0028] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0029] The invention provides an air conditioner.

[0030] refer to figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the air conditioner of the present invention.

[0031] In this embodiment, the air conditioner includes: compressor 10, four-way valve 20, outdoor heat exchanger 30, indoor heat exchanger 40, low pressure tank 50, liquid storage device 60, first control valve 70, second control valve 80 and a controller (not shown in the figure). Among them, the compressor 10, the four-way valve 20, the outdoor heat exchanger 30, the indoor heat exchanger 40 and the low-pressure tank 50 form a refrigerant circulation loop; the inlet of the liquid storage device 60 is connected to the four-way valve 20 through the first control valve 70 , the outlet of the liquid storage device 60 is...

Abstract

The invention discloses an air conditioner. The air conditioner comprises a coolant circulating loop which is composed of a compressor, a four-way valve, an outdoor heat exchanger, an indoor heat exchanger and a low pressure tank. The air conditioner further comprises a liquid storage device, a first control valve and a second control valve. An inlet of the liquid storage device is connected with the four-way valve through the first control valve, and an outlet of the liquid storage device is connected with an inlet of the low pressure tank through the second control valve. The air conditioner further comprises a controller which is connected with the first control valve and the second control valve and used for controlling the opening and closing of the first control valve and the second control valve. The air conditioner further discloses a control method, equipment and a computer readable storage medium for the air conditioner. According to the air conditioner, the heat exchanging efficiency of the air conditioner is ensured; meanwhile, the liquid impact problem of the compressor is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner, its control method, device and computer-readable storage medium. Background technique [0002] At present, when the air conditioner is turned on, the liquid refrigerant in the air conditioner will return to liquid and accumulate in the low-pressure tank. During the liquid return process, especially in the process of heating and starting, there will be a short return The peak of the liquid causes the amount of liquid refrigerant in the low-pressure tank to exceed its maximum allowable value and overflow, thus causing the liquid hammer problem of the compressor. In order to prevent the liquid hammer problem of the compressor when the air conditioner is turned on, the user can reduce the amount of refrigerant in the air conditioner, but this will affect the heat exchange efficiency of the air conditioner. Therefore, it is currently impossible to...
