Title:
AIR-CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/135279
Kind Code:
A1
Abstract:
Provided is an air-conditioning system that is useful in suppressing condensation on cooling piping forming a section of refrigerant piping. This air-conditioning system includes a compressor, an outdoor heat exchanger, an outdoor flow rate adjustment device, a container, and an indoor heat exchanger, which are connected sequentially by means of refrigerant piping. The refrigerant piping between the container and the indoor heat exchanger includes cooling piping. The air-conditioning system further includes container pressure-increasing piping provided with a flow rate control member, and a control unit that controls the operation of the air-conditioning system. One end of the container pressure-increasing piping is connected between the compressor and the outdoor heat exchanger, and the other end is connected between the container and the outdoor flow rate adjustment device. When the control unit determines that a cooling piping condensation condition has been fulfilled, wherein condensation occurs on the cooling piping, the control unit increases the degree of opening of the flow rate control member.
