Air-conditioning system

Abstract

The invention relates to an air-conditioning system which comprises a first circulating module and a second circulating module, wherein the second circulating module comprises a first heat exchanger and a plurality of second heat exchangers; the first heat exchanger is combined with the first circulating module, so that heat exchange can be carried out between a working medium of the first heat exchanger and the first circulating module; each second heat exchanger comprises a heat exchange device and a pneumatic device; each heat exchange device is provided with a first end and a second end; the pneumatic devices are communicated between the first ends and the first heat exchanger, and the second ends are connected with the first heat exchanger, so that a working medium loop is formed between each second heat exchanger and the first heat exchanger; and the pneumatic device drives the working medium which is in a saturated gas state to flow between the heat exchange devices and the first heat exchanger. The air-conditioning system solves the problem that the lubricating oil is taken out of a compressor by entrainment, is left in a pipeline, and can not flow back in the prior art.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an air-conditioning system using a second cycle for temperature regulation. Background technique [0002] Generally speaking, in the technical field of air conditioning, the size of the air conditioning load is often directly proportional to the complexity of the air conditioning technology. In places with huge air-conditioning loads such as large office buildings, large-scale exhibition venues, and transportation transfer stations, these places usually require more complex air-conditioning because these frozen objects usually have different refrigeration needs at different points in time Technology and air conditioning equipment. In order to meet such air-conditioning requirements, the prior art proposes a variable refrigerant flow air-conditioning system. [0003] The existing variable refrigerant flow air conditioning system includes an outdoor unit and a plurality of indoor uni...
