Abstract (en)
[origin: EP4047289A1] An intermediate unit (80) includes a liquid-side pipe (81), a first valve (18), and a refrigerant pressure sensor (48). The liquid-side pipe (81) is connected to a liquid connection pipe (4) connecting a heat source unit (10) and a utilization unit (60) together. A controller (85) of the intermediate unit (80) adjusts the opening degree of the first valve (18) based on a value measured by the refrigerant pressure sensor (48). The pressure of a refrigerant to be sent through the liquid connection pipe (4) from the intermediate unit (80) to the utilization unit (60) is adjusted by the first valve (18).
