An air-conditioning integrated parallel compression transcritical refrigeration rack system and control methods thereof

摘要

An air-conditioning integrated parallel compression transcritical refrigeration rack system has a high-pressure control valve feeding a liquid receiver. The liquid receiver feeds at least one suction group and the at least one suction group feeds a gas cooler. The gas cooler feeds the high-pressure control valve. The system has an AC heat exchanger between the high-pressure control valve and the liquid receiver. The system thereby eliminates the need for a separate suction group, associated componentry and controllers therefor which reduces capital expenditure and installation cost.
