Inventor: OZAWA YUJI
IPC: F25B45/00
Filed: 2000-07-17
Abstract: PROBLEM TO BE SOLVED: To efficiently remove old oil from existing refrigerant piping in order to reuse existing piping, when an old refrigerator/air conditioner is replaced by a new one. SOLUTION: In the method for removing refrigerating machine oil, an old refrigerator/air conditioner is replaced by a new one, while leaving the existing refrigerant piping and then old oil remaining in the piping is removed and operating the new machine. More specifically, the old machine is removed while leaving the existing refrigerant piping in the first step, and a new machine is installed for that piping along with a removing unit in the second step. In a third step, new refrigerant is circulated together with new oil, while operating the new machine and old oil, or a mixture of old oil and new oil, remaining in the refrigerant piping is removed from new refrigerant by means of the removing unit and then is collected and removed. In a fourth step, the removing unit is taken away from the piping after old oil is removed from the refrigerant piping, thus to complete the work.
