Abstract

The present invention provides an air conditioning system capable of switching between cooling and heating, comprising: a reversing valve, a compressor, a first indoor unit, a second indoor unit and an outdoor unit. The reversing valve in the air conditioning system of the present invention can conveniently switch the six connecting pipes between the 2, 2, 2 communication mode and the 3, 3 communication mode, which is similar to the scheme of using two four-way valves in the prior art The same effect can be achieved, but for the air-conditioning system, after using one reversing valve instead of two four-way valves, the pipeline is simplified, it is convenient for pipeline design, frees up space, and can ensure the installability of the compressor, which is convenient for further Design optimization reduces valve and piping costs, especially for air conditioning systems including double suction compressors.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to an air conditioning system. Background technique [0002] When two four-way valves are used in the existing air conditioner system to realize the reversing flow of refrigerant, the pipeline design is relatively complicated, and because the system box space is small, the pipeline direction and installation space are limited, there are many pipelines, and the vibration Stress debugging is difficult. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the present invention provides an air conditioning system capable of switching between cooling and heating, including: a reversing valve, a compressor, a first indoor unit, a second indoor unit and an outdoor unit ;in, [0004] The reversing valve includes: [0005] a body defining a cavity; [0006] The first connecting pipe to the sixth connecting pipe are a...
