Abstract

A refrigeration system includes a gas-liquid heat exchanger, a bypass circuit, a bypass circuit valve, a liquid injection circuit, an injection circuit valve, a temperature sensor and a controller. The gas-liquid heat exchanger performs heat exchange between a high-pressure refrigerant and a low-pressure refrigerant. The bypass circuit receives at least a part of the high-pressure refrigerant that flows from the condenser to the evaporator, bypassing said gas-liquid heat exchanger. The bypass circuit valve adjusts a flow rate of the high-pressure refrigerant that flows into the bypass circuit. The liquid injection circuit receives at least a part of the high-pressure refrigerant passed through the condenser and introduces it into the compressor. The injection circuit valve adjusts a flow rate of the high-pressure refrigerant that flows into the liquid injection circuit. The temperature sensor detects a temperature of the high-pressure refrigerant that flows from the compressor. The controller controls opening and closing of each of the bypass circuit valve and the injection circuit valve based on the temperature detected by the temperature sensor.
