DIGITAL MULTI PRESSURE SWITCH FOR CONTROLLING REFRIGERATOR

摘要

Disclosed is a digital multiple pressure switch capable of measuring and simultaneously processing a refrigerant pressure of a refrigerating device to control the operation of a refrigerating device, to generate an alarm, and to control a cooling fan. To this end, there is provided a digital multiple pressure switch for controlling a refrigerating appliance, which is directly attached to the main body housing and has two or more connection ports incorporating a pressure sensor, a signal processing unit, a control unit, and an information display unit, and a main unit embedded in the main body housing. . By measuring the refrigerant pressure of the refrigerating device digitally with a pressure sensor, the accuracy, reliability and reproducibility of the measurement results are secured. The main components are formed on one digital multi-pressure switch, and the structure is simple by controlling the operation of two or more refrigerator units in a freezer, generating an alarm, and simultaneously controlling the cooling fan with one digital multi-pressure switch. It has the effect of improving the economics and user convenience.;Pressure switch, digital pressure switch, refrigerator pressure control switch, oil pressure control switch, cooling fan control switch
