Abstract
A refrigeration cycle may include a compressor and a flash tank. The flash tank is configured for receiving a refrigerant and separating liquid refrigerant and vapour refrigerant. The compressor is configured for compressing the refrigerant and includes a suction port and an injection port. The flash tank is connected to the injection port of the compressor via an injection valve. A method of controlling injection into the compressor includes determining a pressure in the flash tank and controlling the injection valve based on the determined pressure in the flash tank.
