ABSTRACT:
The invention comprises an apparatus, a method and a system for recovering and purifying a refrigerant contained in a refrigerator, an air conditioning system, a storage tank, or other source. The refrigerant is flowed sequentially through a purifying device, an expansion valve for controlling the flow of the refrigerant, one or two heat exchangers wherein heat is exchanged to convert the refrigerant into a gaseous phase, a second purifying device for separating oil from the refrigerant, a compressor-pump, a third purifying device for filtering moisture, acids, and particulates, and a moisture indicator monitors the amount of moisture present in the recovered refrigerant. The refrigerant then may be flowed into a receiving tank, and thence dispensed therefrom back into the refrigerant source, a storage tank, or recirculated again through the apparatus. The apparatus also comprises means for leak testing the refrigerant source, and for pressure-clearing obstacles from the refrigerant source.
