摘要： A refrigeration system includes a compressor; a condenser; an expansion valve having a body with an expansion valve inlet and an expansion valve outlet; an evaporator all arranged in a refrigeration circuit; and a controller. The expansion valve body has a pathway comprising an inlet body capillary tube flow-connected to the expansion valve inlet, and an outlet body capillary tube flow-connected to the expansion valve outlet. The expansion valve comprises a solenoid operated valve element that is selectively positionable between the inlet body capillary tube outlet and the outlet body capillary tube inlet. The controller digitally controls the valve element to position the valve element either to allow flow through the pathway in an open position or to block flow through the pathway in a closed position.

摘要： A refrigeration system, includes a main refrigeration system. The main refrigeration system includes a main refrigerant, a main compressor, a main condenser coil, a pre-metering device, a main metering device, a main evaporator, and a secondary refrigeration system. In flow sequence, the main refrigerant within the main refrigeration system is compressed by the main compressor, condensed by the main condenser coil, dropped in pressure by the pre-metering device, cooled by the secondary refrigeration system, dropped in pressure by the main metering device, vaporized by the main evaporator and returned to the main compressor. The secondary refrigeration system includes a secondary refrigerant, a secondary compressor, a secondary condenser coil, a secondary metering device, a secondary evaporator having a main refrigerant cooling path and a secondary refrigerant evaporator path in heat transfer communication. In flow sequence, the secondary refrigerant in the secondary refrigeration system is compressed by the secondary compressor, condensed by the secondary condenser coil, dropped in pressure by the secondary metering device, and vaporized by the evaporator path by heat transfer from the cooling path carrying the main refrigerant, and returned to the secondary compressor. The main condenser coil and the secondary condenser coil are located together in a housing to be cooled by the same flowing media. The secondary evaporator is a co-axial pipe heat exchanger.
