3 Recovery from air-conditioning system Liquid transfer Air-conditioning installations may have service stop valves installed in the pipe lines. When recovering refrigerant from such a system, liquid should be transferred first because the quantity can be rather large. The push-pull method is recommended. The system’s liquid pipe should be connected to the recovery cylinder’s liquid side. The cylinder’s vapour side should be connected to the recovery inlet (suction) side. The discharge side recovery unit should be connected to the suction pipe on the air conditioning system. If there are available valves on the systems receiver (on the high pressure side), the recovery unit discharge side could be connected here as well. Liquid flows now from the liquid side of the air-conditioning system and into in the cylinder. The recovery unit will keep the pressure inside the cylinder lower than in the air-conditioning system and keep up the liquid flow. Vapour transfer When liquid transfer is completed there will still be some refrigerant vapour left in the system. To transfer all refrigerant to the recovery cylinder, connect the suction hose from the recovery unit to the gas pipe on the air-conditioning system. Connect the recovery unit discharge outlet hose to the recovery cylinder’s vapour side. Run the recovery unit until the suction gauge reads –0.7 bar (0.3 bar absolute) or lower. Recovery from mobile air conditioning (MAC) system Vapour transfer MAC systems are normally equipped with service valves on the compressor’s high and low-pressure sides. The refrigerant charge on such system is rather small and therefore only vapour transfer is required. Connect the hose from the recovery unit’s suction/ inlet side to the air-conditioning system’s compressor low-pressure side and the discharge hose to the vapour valve on the recovery cylinders. Run the recovery unit for 3 – 5 minutes. Connect another hose to the system’s high-pressure side and complete the recovery. Run the recovery unit until pressure gauges reads –0.7 bar (0.3 bar absolute) or lower. Refrigerant reclaiming Reclamation means to reprocess used refrigerant, typically by distillation, to conditions similar to that of virgin product specifications. Reclamation removes contaminants such as water, chloride, acidity, high boiling residue, particulates/solids, non-condensable, and impurities including other refrigerants. Chemical analysis of the refrigerant shall be required to determine that appropriate specifications are met. The identification of contaminants and required chemical analysis shall be specified by reference to national or international standards for new product specifications. Reclamation typically occurs at a reprocessing or manufacturing facility. Commercial units are available for use with R12, R22, R134a, etc, and are designed for the continuous use required on a long run recovery recycling procedure. 82 Refrigerant ManagementPDF Image | Manual for Refrigeration Servicing Technicians
