Circuit Diagram OF Air Flow System In Refrigerator

on

Introduction

In this circuit you should understand the refrigerator cooling system.Inthis circuit there are three motors  used
which includes a compressor motor,condenser fan motor and evaporator fan motor.This circuit explains the air flow system of refrigerators.There are three control relays are installed in this circuit and two main switches,one is for condenser and the other is for evaporator.

Explanation

In this circuit thermostat is used it's function is to control the temperature present in refrigerators.When this switch turns on all the control relays energizes and starts the condensor and evaporator.But the compressor motors remain in it's off position because of the two switches which are open and connected in series with the compressor motor.By this the air flow system stars flowing the air in refrigerator.
