Problems solved by technology

[0002] General air-conditioning and refrigeration systems are composed of refrigeration compressors, high-temperature heat source heat exchangers, throttling components and low-temperature heat source radiators. Under certain operating conditions, the safety and effectiveness of the system can be guaranteed, but when the operating conditions exceed a certain range In this case, the reliable operation of the system cannot be guaranteed due to the limited ability to adjust the amount of circulating refrigerant in the system.

Embodiment Construction

[0019] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] like figure 1 As shown, the air-conditioning system according to the present invention includes a compression cycle in which a compressor 1 is arranged in series, and the air-conditioning system also includes a discharge pipe for transporting the liquid refrigerant in the intake line of the compressor 1 to the compressor 1 in-circuit liquid refrigerant transfer system. The present invention transfers the liquid refrigerant in front of the compressor 1 to the compressor 1 by setting up a liquid refrigerant transfer system to effectively control the refrigerant circulation amount, ensure the effectiveness and safety of the air conditioning system operation, and greatly expand the operation of the air conditioning unit range; and in the heating process, the liquid refrigerant in front of the compressor is transferred to the compressor, so that the low...

Abstract

The invention provides an air conditioning system. The air conditioning system comprises a compression cycle and a liquid refrigerant transferring system, wherein a compressor is connected in series in the compression cycle; the liquid refrigerant transferring system is used for conveying a liquid refrigerant in an air inlet pipeline of the compressor into an exhaust pipeline of the compressor. According to the air conditioning system provided by the invention, the liquid refrigerant in front of the compressor is transferred to the compressor through the liquid refrigerant transferring system, so that the refrigerant circulation amount is effectively controlled, the running effectiveness and safety of the air conditioning system are ensured, and the running range of an air conditioning unit is expanded greatly. Moreover, in a heating process, the liquid refrigerant in front of the compressor is transferred into the compressor, and a low-pressure liquid refrigerant is directly transferred to a high-pressure liquid refrigerant, so that the aim of rapidly enhancing the heating effect is fulfilled.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioning system. Background technique [0002] General air-conditioning and refrigeration systems are composed of refrigeration compressors, high-temperature heat source heat exchangers, throttling components and low-temperature heat source radiators. Under certain operating conditions, the safety and effectiveness of the system can be guaranteed, but when the operating conditions exceed a certain range In this case, the reliable operation of the system cannot be guaranteed due to the limited ability to adjust the amount of circulating refrigerant in the system. Especially for multi-connected air-conditioning units, due to the relatively large amount of refrigerant itself and the relatively large variability of indoor operating loads, the requirements for the circulation of refrigerant in the system are even higher. Contents of the invention [0003] The present inve...
