Integral leakage detection in an evaporator for a refrigerating machine with a further measurement

摘要

The invention concerns a method of determining the properties of an object containing a hollow region (8), preferably a refrigerator evaporator, plus a device suitable for carrying out the method. The invention calls for the object being examined (7) to be tested overall for leaks. In addition to the leak test, the volume of the object being examined (7) and/or the rate of flow of the coolant through a nozzle (11) in the object (7) is measured.
