CONTROL OF COMPOSITION CHANGE DURING TRANSFER OF MIXED LIQUID OF NON-AZEOTROPIC COOLING MEDIUM

摘要

PURPOSE: To provide the subject controlling method useful for filling a cooling medium into a cylinder at a cooling-medium manufacturer, filling the cooling medium into an air conditioning machine at an air-conditioning-machine manufacturer, as well as useful in the field of filling the medium from a service can to the air conditioning machine during repairing or during the supplementation of leakage. etc. ;CONSTITUTION: A non-azeotropic cooling-medium mixture filled in the first cooling-medium container and consisting of R32, R125 and R134a is dividedly transferred into at least two of the second cooling-medium containers. The objective composition change-controlling method during the transferring of the non-azeotropic cooling-medium mixture comprises a process in which the composition of R32 and R125 in the mixed liquid filled in the first cooling- medium container is respectively adjusted to 23.4-24.0wt.% and 25.2-26.0wt.% before the first turn of transferring.;COPYRIGHT: (C)1996,JPO
