Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/078808
Kind Code:
A1
Abstract:
An air conditioner (10) is provided with a refrigerant circuit (13) and a refrigerant. The refrigerant circuit (13) includes a compressor (1), a condenser (2), a pressure adjustment valve (3), and an evaporator (4). The refrigerant is R32. The pressure adjustment valve (3) includes a flow path (33) through which the refrigerant flowing from the condenser (2) is caused to flow into the evaporator (4), a pressure reference chamber (S2) which is partitioned off from the flow path (33) and which is filled with inert gas, and a valve portion (34) disposed in the flow path (33). The pressure adjustment valve (3) can adjust the flow rate of the refrigerant flowing through the flow path (33) by adjusting the valve opening degree of the valve portion (34). The valve portion (34) operates so as to increase the valve opening degree when the pressure inside the flow path (33) becomes higher than the pressure inside the pressure reference chamber (S2), and to decrease the valve opening degree when the pressure inside the flow path (33) becomes lower than the pressure inside the pressure reference chamber (S2).
