Compressor-assisted absorption refrigeration system

In an absorption refrigeration system comprising generator means for generating a refrigerant vapor from a refrigerant solution, condenser means for condensing said refrigerant vapor from said generator means to form condensed refrigerant, evaporator means for evaporating said condensed refrigerant and for cooling a surrounding material, absorber means for absorbing refrigerant vapor from said evaporator means into said refrigerant solution, and a heat exchanger for circulating said solution through said absorber means and said generator means, said generator means, condenser means, evaporator means, absorber means and heat exchanger being connected in a refrigerant circuit, the improvement comprising:

• an oiled compressor, connected to said refrigerant circuit, for compressing said refrigerant vapor said compressor discharging oil into said refrigerant circuit;
• oil separating means downstream of said compressor for separating oil from said refrigerant solution and returning said oil to said compressor;
• a bleed line, conducting said refrigerant solution from a portion of said refrigerant circuit between said absorber means and said generator means to a line between said compressor and said oil separating means and
• valve means on said bleed line for permitting fluid flow through said bleed line only when said oiled compressor and said absorber means are operating,
• said refrigerant solution being miscible in said oil and being separable by evaporation from said oil.
