FIELD: heating.
SUBSTANCE: invention is related to refrigerating equipment. Method for determination of technical condition of household compression refrigerator subsystems consists in the fact that the following diagnostic parametres are measured: air temperature and Freon temperature in points of refrigerator unit subsystems. Values of sought for parametres of household compression refrigerator are defined indirectly, by substitution of parametre direct measurements results in calculated dependencies. Ambient air temperature is measured. Pressure value is calculated, or other Freon temperature in investigated subsystems according to appropriate expressions of similarity invariants of refrigerating unit functioning. Calculated values of pressure or temperature are compared to their appropriate rated values, and conclusion is made on compliance of technical condition of subsystems to their specified condition.
EFFECT: realisation of in-place diagnostics of technical condition of household compression refrigerator subsystems.
