Abstract

A refrigeration system has a refrigeration control assembly and separate compressor-driver, condenser and evaporator assemblies connected by refrigerant lines to the refrigeration control assembly. The assemblies are relocatable with respect to each other in parallely, longitudinally or angularly related portions. The refrigeration control assembly has multiple ports with quick disconnect sealing joints to the refrigerant lines. The refrigeration control assembly is equipped to connect supplemental compressor, condenser and evaporator assemblies and independent condenser and evaporator units. The refrigerant control valves with the possible exception of expansion and pressure control valves at an evaporator are in the refrigerant control assembly, which also holds the liquid filter, the liquid accumulator, the suction accumulator and the oil separator. The liquid accumulator, suction accumulator and oil separator have cylindrical chambers and rotatable pendulums with passageways and openings to permit flow of the desired fluids at any orientation.
