Abstract

Portable, hand carryable acid purification and flushing and transfer systems are provided for use in various refrigerant recovery, recycling and flushing operations performed in conjunction with an air conditioning circuit. The acid purification system is disposed within a carrying housing and includes an accumulation/distillation type acid separator piped in series with a pair of cylindrical dual core filter assemblies. A pair of refrigerant inlet and outlet fittings are externally mounted on the housing. By connecting these fittings in a forced flow refrigerant circuit the refrigerant is passed sequentially through the acid separator and the first and second filter assemblies to cleanse the refrigerant of acid and particulate impurities therein. The portable flushing and transfer system is also disposed in a carrying housing and includes a high capacity liquid refrigerant transfer pump piped in series with a check valve and a relief valve. Inlet and outlet valves mounted on the housing may be connected to an air conditioning circuit to provide for rapid recycling or recovery of its refrigerant. An adapter kit is furnished with the flushing and transfer system and includes connecting hoses, strainer and filtration apparatus, and specially designed adapter fittings that permit the system to be connected to a variety of air conditioning circuits.
