Embodiment Construction

[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The invention provides an air conditioning system, referring to figure 2 , which discloses the first embodiment of the present invention. In this embodiment, the air conditioning system includes a compressor unit 10 , an outdoor unit 20 , an indoor unit 30 , a four-way valve 40 and a refrigerant adjustment unit 50 .

[0037] The compressor unit 10 is used to compress the refrigerant, which includes a compressor, an oil separator and a gas-liquid separator. The working process of the compressor unit 10 compressing the refrigerant is well known to those skilled in the art and will not be described in detail here. Add explanation. The compressor unit 10 has an inlet 11 and an outlet 12 .

[0038] The outdoor unit 20 is used for heat exchange between the refrigerant and the outdoor environment, thereby releasing...

Abstract

The invention discloses an air-conditioning system which comprises a compressor unit, an outdoor unit and an indoor unit. The indoor unit is provided with an indoor evaporator, a first expanding valve, a refrigerant adjusting storage device and a second expanding valve are sequentially connected between the outdoor unit and the indoor unit, refrigerant filling amount and refrigerant circulating volume in the compressor unit, the outdoor unit and the indoor unit are controlled through the second expanding valve and the first expanding valve, the performance of the air-conditioning system is improved by adjusting the refrigerant filling amount and the refrigerant circulating volume, the second expanding valve is serially connected with the first expanding valve, so that better throttling effect can be obtained as compared with a single expanding valve, the refrigerant circulating amount can be more accurately controlled, and the compressor unit can stably run at lower frequency, so that the running capacity range of the compressor unit is widened.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and method for adjusting refrigerant filling and refrigerant circulation. Background technique [0002] An air conditioning system generally consists of a compressor, an outdoor unit, an indoor unit, and a throttling device. The throttling device generally adopts a capillary tube or an expansion valve. The amount of refrigerant circulation and refrigerant filling required by the air conditioning system are different under different working conditions. In order to achieve the optimal operation of the air conditioning system, it is necessary to adjust the refrigerant circulation and refrigerant filling of the air conditioning system. [0003] In order to adjust the refrigerant circulation of the air conditioning system, an expansion valve with adjustable opening is added to the air conditioning system, and the refrigerant circulation is controll...
