Portable refrigerant recycling unit for heat exchange with separate recovery unit

A refrigerant recycle unit for use with a separate refrigerant recovery unit for recycling and recovering compressible refrigerant from a refrigeration system, the refrigerant recovery unit having refrigerant recovery input and output means, the refrigerant recovery output means delivers the recovered refrigerant to a refrigerant receiver, the refrigerant recovery unit discharges heat when recovering the refrigerant, said refrigerant recycle unit comprising:

• refrigerant input means for receiving the refrigerant from the refrigeration system;
• heat receiving means for receiving the heat discharged from the separate refrigerant recovery unit;
• heat exchanger means for transferring the heat from said heat receiver means to the refrigerant from said refrigerant receiver to vaporize the refrigerant;
• oil separator means downstream from said heat exchanger means for separating oil from the vaporized refrigerant;
• filter means downstream from said oil seperator means for filtering the vaporized refrigerant;
• refrigerant output means for presenting the vaporized refrigerant from said filter means to the refrigerant recovery input means;
• sub-cooling input means for receiving vapor refrigerant from the refrigerant receiver;
• vapor flow restriction means for restricting the vapor refrigerant flow from said sub-cooling input means to said refrigerant output means;
• heater means for heating said oil seperator means;
• means for housing said refrigerant input means, said heat receiving means, said heat exchanger means, said oil seperator means, said filter means, said refrigerant output means, said sub-cooling input means, said vapor flow restriction means, and said heater means;
• and
• wherein said heat receiving means comprises;
• vent means in said housing means at a location adjacent the recovery unit, said vent means being receptive to the heat discharged from the recovery unit, and
• fan means disposed on said housing means for drawing air containing the heat discharged from the recovery unit through said vent means for use by said heat exchanger means.
