Patent
·
OSTI ID:6590743
This patent describes a refrigeration system including a compressor having a suction side and a discharge side, a first heat exchanger and a second heat exchanger being connected to the compressor, an expansion device disposed between the heat exchangers and having through one end portion thereof a fluid flow passage that opens through an opposite end portion thereof. The one end portion is connected in fluid communication with one of the heat exchangers, and means disposed in the fluid flow passage for throttling liquid refrigerant. A coupling mechanism is described for removably coupling the expansion device to the other of the heat exchangers, comprising: a retainer being slidably and removably fitted in a fluid tight manner at the expansion device opposite end portion and having an opening therethrough in alignment with the fluid flow passage of the expansion device and further having an annular flange disposed in the opening, a liquid supply line having one end thereof connected in fluid communication with the other heat exchanger and the other end thereof securely fitted in the retainer opening in abutting engagement with the annular flange in a fluid tight manner, and a collar means disposed about the liquid supply line and being movable therealong between a first position wherein the collar means is spaced apart from the retainer and a second position wherein the collar means peripherally overlaps the retainer and removably secures the liquid supply line to the expansion device.
