ABSTRACT:
The refrigeration system is provided with a bundle of refrigeration tubes extending through heat exchange fins, with the bundle forming a condenser section, a receiver section and a subcooler section. A sight glass is positioned in the line between the receiver and the subcooler to facilitate the refrigerant charging process. The system also includes a floating head arrangement which allows the condenser pressure to fluctuate with the ambient temperature. A solenoid valve leading to an expansion valve cycles on/off in response to compressor suction pressure. A check valve insures that a column of liquid is always immediately upstream from the expansion valve.
