REFRIGERANT LOADING DEFICIENCY DETECTOR OF REFRIGERATOR

摘要

PURPOSE: To provide a refrigerant loading deficiency detector of a refrigerator for securely detecting the loading deficiency of a refrigerant without being influenced by the state of freezing load. ;CONSTITUTION: There are provided pressure difference detector 10 for detecting a pressure difference between pressure at a refrigerant inlet 3a of a fluid reception pan 3 connected on the middle of a high pressure piping 8 located between a condenser 2 of a freezing cycle and an expansion valve 4 and pressure at a refrigerant outlet 3b, and compressor for issuing a signal indicative of the loading deficiency of a refrigerant loaded in a freezing cycle when the difference pressure exceeds the reference.;COPYRIGHT: (C)1993,JPO&Japio
