ABSTRACT:
Refrigerant is circulated through an economized refrigeration system including a compressor, a gas cooler, a main expansion device, an economizer heat exchanger and an evaporator. After cooling, the refrigerant splits into an economizer flow path and a main flow path. Refrigerant in the economizer flow path is expanded to a low pressure and exchanges heat with the refrigerant in the main flow path in the economizer heat exchanger. The refrigerant in the main flow path is then expanded and heated in the evaporator and enters the compressor, completing the cycle. An accumulator positioned between the economizer heat exchanger and the compressor stores excess refrigerant in the system, regulating the amount of refrigerant in the system and the high pressure in the system. The amount of refrigerant in the accumulator is controlled by regulating the economizer expansion device. By adjusting the amount of refrigerant in the accumulator, the amount of refrigerant in the system, and therefore the high pressure of the system, can be regulated.
