<p><P>PROBLEM TO BE SOLVED: To provide a refrigerant processor that processes a refrigerant alone for a vehicle with a reciprocating engine and a hybrid vehicle (HV)/an electric vehicle (EV). <P>SOLUTION: This refrigerant processor includes: a high-pressure hose 2 and a low-pressure hose 3 respectively attached/detached to/from a high-pressure service valve VH and low-pressure service valve VL of a vehicle air-conditioning system U; a compressor 12 collecting a refrigerant from the vehicle air-conditioning system U; an oil separator 10 separating refrigerating machine oil from the collected refrigerant; a refrigerant collection tank 19 storing the separated refrigerant; and valves 26, 27 to which the high-pressure hose 2 and low-pressure hose 3 are connected. The high-pressure hose 2 and low-pressure hose 3 are connected to the valves 26, 27 on the side of a device body 1. A closed circuit is formed which circulates between the oil separator 10 and the refrigerant collection tank 19 by driving the compressor 12, and then the refrigerant is circulated in the closed circuit. Thereby, pipe line cleaning is performed for removing the refrigerating machine oil remaining in a pipe line. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
