Embodiment Construction

[0050] 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.

[0051] The invention provides a control method of an air conditioner.

[0052] Reference figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the air conditioner control method of the present invention.

[0053] In an embodiment, the air conditioner control method includes:

[0054] Step S10, after the refrigerant exchanges heat through the indoor heat exchanger, the refrigerant after the heat exchange is controlled to become a gas-liquid mixture through the throttle valve;

[0055] In this embodiment, refer to figure 2 The air conditioner includes: compressor 1, four-way valve 2, indoor heat exchanger 3, throttle valve 4, outdoor heat exchanger 5, flasher 6, heat storage device 7, electromagnetic three-way valve 8 and one-way valve 9; Among them, the compressor 1 is connected to the outdoor heat e...

Abstract

The invention discloses a control method for an air conditioner. The method comprises the steps as follows: after a refrigerant is subjected to heat exchange through an indoor heat exchanger, the refrigerant after heat exchange is controlled to be throttled by a throttling valve to be changed into a gas-liquid mixture; the gas-liquid mixture is controlled through the flow direction of an electromagnetic three-way valve to enter a flash tank; one part of the gas-liquid mixture subjected to flashing by the flash tank is controlled to be throttled by the throttling valve and then subjected to heat exchange through an outdoor heat exchanger to be changed into a gaseous mixture, the gaseous mixture is mixed with the other part of the gas-liquid mixture, and the mixture flows into a compressor. The invention further discloses a control device for the air conditioner and the air conditioner. With the method, the device and the air conditioner, the working medium flowing through the outdoor heat exchanger can be reduced, so that the loss of environmental heat is reduced, the frost quantity is reduced, little heat is lost due to the small frost quantity, then the working medium temperature at the inlet of the compressor is increased, and the indoor heating quantity is increased.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method, device and air conditioner. Background technique [0002] At present, when the air conditioner is operating in the heating mode, the whole machine operates in a normal cycle, that is, the working fluid discharged from the compressor is guided by the four-way valve to flow into the indoor heat exchanger, and after the heat exchange is completed, it is throttled by the throttle valve. It flows into the outdoor heat exchanger for heat exchange, and then flows out through the four-way valve and returns to the compressor inlet. However, under this ordinary control method of the flow direction of the refrigerant directly flowing through the outdoor heat exchanger, the refrigerant will absorb heat by the environment after the heat exchange through the outdoor heat exchanger (there is frosting). In this case, the compressor The imported wor...
