Abstract
The supercritical refrigerating circuit has a first pressure reducing valve for reducing pressure of refrigerant flows into a first evaporator and a second pressure reducing valve for reducing pressure of refrigerant flows into a second evaporator. The first pressure reducing valve further controls refrigerant pressure at an outlet of a gas cooler. Accordingly, the supercritical refrigerant circuit is controlled without increasing the number of the pressure reducing valve.
