The working principle of the electrical system of the indirect cooling supermarket refrigerated showcase The working principle of the electrical system
the supermarket refrigerated showcase The forced air circulation is accelerated by the fan in the freezer to enhance the heat exchange speed of the evaporator. So as to achieve the purpose of cooling food.
inter-cooled supermarket refrigerated showcase: the main difference between the cabinet and the direct-cooled supermarket refrigerated showcase is electrical, and the electrical difference lies in the automatic frost circuit, which is a typical inter-cooled supermarket refrigerated showcase electrical system. The difference between it and the ordinary supermarket refrigerated showcase is that a defrosting circuit is added, and the compressor's work is controlled by the defrosting circuit. The current path of
cooling is shown in the indirect cooling supermarket refrigerated showcase electrical system analysis. 1. When the current path of refrigeration is just turned on, due to the high temperature in the cabinet, the thermostat is in the normally on state, the defrost thermostat is in the disconnected state, and the contacts 1, 3 of the defrost timer are connected In this way, the compressor and fan motors are energized and run at the same time, but the defrost timer does not work because the defrost thermostat is disconnected. With the operation of the compressor, the refrigeration system starts to work and refrigerate. When the temperature of the freezer compartment drops to s℃~8℃, the defrosting controller is automatically turned on, the defrosting timer motor is energized and starts to count. When the accumulated time is about When it reaches 8h, the defrost timer contacts 1 and 3 are disconnected. Contacts I and 2 are turned on. At this time, the compressor, fan motor and defrost timer circuit are all cut off and stop working, but the defrost circuit is switched on and the defrost starts. supermarket refrigerated showcase compressor circuit during refrigeration, the upper end of the power plug has a > thermostat, a > defrost timer contact 1, 3 a > overload protector, a > compressor start branch (compressor start coil, PTC starter and Operating capacitor) or compressor operating coil at the lower end of a > power plug.
