Embodiment 1

[0036] See figure 1 , The air conditioner of the first embodiment includes: a compressor 2, an indoor heat exchanger 3 and an outdoor heat exchanger 4 connected by pipelines to form a circuit, the indoor heat exchanger 3 and the outdoor heat exchanger 4 A throttling device 6 is connected between; an adjustable refrigerant storage 1 is connected between the outdoor heat exchanger 4 and the throttling device 6, and the adjustable refrigerant storage 1 includes a cylindrical shell 101, and is arranged on the column A plug member 102 inside the cylindrical casing 101 and reciprocating along the axial direction of the cylindrical casing 101, the plug member 102 is sealed with the inner side wall of the cylindrical casing 101, and the plug member A liquid storage chamber 103 is formed between the working surface of 102 and the cylindrical shell 101; the cylindrical shell 101 is provided with a liquid inlet 104 and a liquid discharge port 105 communicating with the liquid storage cha...

Embodiment 2

[0071] The difference from the first embodiment is that in the air conditioner of the second embodiment, the lower end of the cylindrical casing 101 of the adjustable refrigerant storage 1 is open, so that the inner cavity of the cylindrical casing 101 does not have an adjustment chamber 106 .

Abstract

The invention relates to the technical field of air conditioning, and provides an air conditioner and a refrigeration control method thereof. Wherein, the air conditioner is connected with an adjustable refrigerant accumulator between the outdoor heat exchanger and the throttling device, and the accumulator includes a cylindrical shell and a plug part, and a liquid storage chamber is formed between the plug part and the cylindrical shell; the cylindrical shell The body is provided with a liquid inlet and a liquid discharge port; the plug part is connected with a driving mechanism, and the driving mechanism controls the movement of the plug part according to the refrigerant pressure value in the refrigeration circuit. In this scheme, when the high pressure value of the refrigerant in the air conditioner is too high, the driving mechanism drives the plug member to move so that the volume of the liquid storage chamber increases, so that a part of the refrigerant in the air conditioner pipeline is stored in the liquid storage chamber, Reduce the pressure of the refrigerant in the pipeline of the air conditioner until the high pressure value of the refrigerant meets the requirements, and at this time the control plug part of the driving mechanism remains stationary. Therefore, the air conditioner can normally cool in a high temperature or even an ultra-high temperature environment, effectively solving the problem that users cannot cool at high temperatures.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner and a refrigeration control method thereof. Background technique [0002] The maximum operating temperature of the traditional T3 air conditioner is 52°C. Generally, the air conditioner manufacturer will leave a design allowance of 2 to 3°C in the design, that is, the maximum operating ambient temperature of the air conditioner is about 55°C. But even if there is such a margin, after the product is installed in the user's home, there are still frequent failures, and the maintenance rate remains high. In particular, the environment in the Middle East is relatively harsh. When the weather forecast is that the atmospheric temperature is around 45 °C, the air temperature after being exposed to the sun outside is often as high as 60 °C or more, or even between 67 and 68 °C. In such a temperature environment, the conventional T3 working condition air condit...
