Using non gas analyzer method about diagnosing of leakage of the refrigerating agent from refrigerating system of the household refrigerator «NОRD» - dh -239

Abstract

In this work it is demonstrated the theoretical bases and results of experiments regarding distribution of temperature on a surface of the evaporator and in volume of the freezing chamber of the household DH-239 refrigerator (HR) working with isobutene. The values of temperature were received by means of computing algorithm of mathematical model [1] and defined experimentally, depending on a dose of filling are compared by isobutene of refrigerating system and ambient temperature. The action principle, the location of the sensor and settings of the device of automatic equipment signaling about leak of a coolant from the HR refrigerating system, are proved at various uptake of a temperature regulator, in the range of ambient temperature from 16 up to 43 degrees Celsius.
