REFRIGERANT FILLING APPARATUS AND METHOD

摘要

A method (600)of charging a refrigeration system (100) includes supplying (614) a substantially evacuated refrigerant loop of the refrigeration system with a refrigerant fluid. The method monitors (616, 352) at least a temperature associated with a fluid line forming part of a refrigerant loop of the refrigeration system and detects (620) a relatively rapid change (404, 414) in the temperature between two substantive equilibrium values (402,406; 412, 416). In response to the detection of the rapid change, the method ceases (622) the charging of the refrigeration system.
