Claims
- 1. An apparatus for reclaiming refrigerant comprising, in combination, cleaning means for removing gaseous or liquid refrigerant from a container, vaporizing all of said liquid refrigerant and separating oil from the gaseous refrigerant, a compressor for receiving and compressing said gaseous refrigerant from said container, a condenser for receiving and condensing said gaseous refrigerant from said compressor, storing means for receiving and storing said liquid refrigerant from said condenser, removal means for removing condensed refrigerant out from said storing means, and evacuations means for evacuating high pressure gaseous refrigerant from the entire apparatus after all of said condensed refrigerant has been removed said storing means; said evacuation means comprised of the three-way solenoid valve and an operator activated switch functionally associated with said solenoid valve wherein the activation of said switch causes said evacuation of high pressure gaseous refrigerant; and said evacuation means located adjacent to and in fluid communication with the exit of said compressor.
- 2. The apparatus of claim 1 wherein said evacuation means is further comprised of means for enabling fluid communication between said cleaning means and said removal means.
- 3. An apparatus for reclaiming refrigerant comprising, in combination, cleaning means for removing gaseous or liquid refrigerant from a container, vaporizing all of said liquid refrigerant and separating oil from the gaseous refrigerant, a compressor for receiving and compressing said gaseous refrigerant from said container, a condenser for receiving and condensing said gaseous refrigerant from said compressor, means for receiving and storing said liquid refrigerant from said condenser, and valve means for the introduction of refrigerant into said cleaning means comprised of first and second solenoid valves, said first solenoid valve preventing flow out of said inlet means when closed, and said second solenoid valve preventing flow into said cleaning means when closed.
- 4. The apparatus of claim 3 wherein said valve means is further comprised of sight glass means for viewing the refrigerant located between and in fluid communication with said first and second solenoid valves.
- 5. The apparatus of claim 3 wherein said first and second solenoid valves are operatively associated with an operator-activated switch, said switch activating both first and second solenoid valves and allowing refrigerant to enter into said cleaning means.
- 6. An apparatus for reclaiming refrigerant comprising, in combination, means for removing gaseous or liquid refrigerant from a container, vaporizing all of said liquid refrigerant and separating oil from the gaseous refrigerant, a compressor for receiving and compressing said gaseous refrigerant from said container, a condenser for receiving and condensing said gaseous refrigerant from said compressor, storing means for receiving and storing said liquid refrigerant from said condenser, and valve means for the removal of condensed refrigerant from said storing means comprised of first and second solenoid valves, said first solenoid valve preventing flow out of said storage means when closed, and said second solenoid valve preventing flow into said storage means when closed.
- 7. The apparatus of claim 6 wherein said valve means is further comprised of sight glass means for viewing the refrigerant located between and in fluid communication with said first and second solenoid valves.
- 8. The apparatus of claim 6 wherein said first and second solenoid valves are operatively associated with an operator-activated switch, and switch activating both first and second solenoid valves and allowing refrigerant to flow out of said storage means.
- 9. An apparatus for reclaiming refrigerant comprising, in combination, means for removing gaseous or liquid refrigerant from a container, vaporizing all of said liquid refrigerant and separating oil from the gaseous refrigerant, oil accumulator means for receiving and removing oil mist and any liquid refrigerant from said gaseous refrigerant from said container, a compressor for receiving and compressing said gaseous refrigerant from said oil accumulator means, a condenser for receiving and condensing said gaseous refrigerant from said compressor, and means for receiving and storing said liquid refrigerant from said condenser; said oil accumulator means is comprised of a canister containing a directional gutter, of liquid collection reservoir, and a bifurcated tube, whereby said gaseous refrigerant from said container is caused to circulate within said canister by said directional gutter, oil mist accumulates in said liquid collection reservoir, and gaseous refrigerant exits said oil accumulator means via said bifurcated tube.
- 10. An apparatus for reclaiming refrigerant that has cleaning means for holding refrigerant within the apparatus while repeatedly cleaning and cooling the refrigerant, said cleaning means comprising, oil accumulator means for removing oil mist and any liquid refrigerant from gaseous refrigerant, a compressor for receiving, compressing and discharging gaseous refrigerant from said oil accumulator means, means for condensing the gaseous refrigerant to a liquid, means for conducting the liquid refrigerant into a closed chill tank, means for withdrawing the liquid refrigerant from said chill tank and passing it successively through a filter-drier, means for expanding the refrigerant into a gaseous state, and a fluid conduit within the chill tank extending upwardly from the lower portion of the chill tank, and means outside the chill tank for connecting said fluid conduit in fluid communication with the intake of said oil accumulator means.
- 11. The apparatus of claim 10 wherein said oil accumulator means is comprised of a canister containing a directional gutter, a liquid collection reservoir, and a bifurcated tube, whereby said gaseous refrigerant from said container is caused to circulate within said canister by said directional gutter, oil mist accumulates in said liquid collection reservoir, and gaseous refrigerant exits said oil accumulator means via said bifurcated tube.
