  • Patent number: 8978394
    Abstract: A convertible refrigerant recovery, recycle, and recharge unit, comprising a control valve array, a vacuum pump, an oil separator, an oil-less compressor, and one or more storage tanks. The vacuum pump and the oil separator are in flow communication with the control valve array, the oil-less compressor is in flow communication with the oil separator, and the storage tanks are in flow communication with said oil-less compressor. The control valve array receives refrigerant from a refrigerant containing device wherein the oil-less compressor draws the refrigerant into said the storage tanks. The unit is compatible with a plurality of refrigerant types without cross-contamination of the refrigerant due to the oil-less compressor and conversion cycle whereby the vacuum pump is activated to remove residual refrigerant from the unit. A refrigerant identifier sensor is in flow communication with the system and can detect contaminants and selectively open and close the storage tanks.

  • Patent number: 8082750
    Abstract: A device for automatic processing of contaminated refrigerant from an air conditioning system, said device comprising a compressor for compressing refrigerant. Said device further comprising an oil separator, said oil separator receiving compressed refrigerant from said compressor; said oil separator further including means for draining oil separated from said compressed refrigerant. Said device further comprising a storage tank, said storage tank receiving and temporarily containing said compressed refrigerant from said oil separator. Said storage tank including a vapor port and a liquid port. Said device further comprising a vacuum pump for creating low pressure within said device during evacuation of refrigerant. Said device further comprising a low pressure service hose for connecting said device to said air conditioning system. Said device further comprising a high pressure service hose for connecting said device to said air conditioning system.
