| description | A refrigerant loop including: a main loop and a bypass loop. The main loop includes: at least one heat exchanger; a first expansion valve configured to control flow of a refrigerant through the refrigerant loop; a compressor; a sensor for detecting at least one of a discharge superheat (SH) from the compressor, a discharge temperature, a discharge pressure, a suction SH, a suction temperature, a suction pressure, a temperature of a refrigerant, and a time period. The bypass loop includes a second expansion valve configured to control flow of the refrigerant through the refrigerant loop. A controller controls the opening and closing of the first expansion valve and the second expansion valve based on the detected discharge SH, the discharge temperature, the discharge pressure, the suction SH, the suction temperature, the suction pressure, the temperature of the refrigerant, and the time period. |
