The first step is to identify the components of the refrigeration system. The compressor, condenser, evaporator, and expansion valve are all essential parts of a refrigeration system. Once you have identified these components, you can begin the startup process.The first step in starting a refrigeration system is to turn on the power supply. Once the power is turned on, you can start the compressor. Next, you will need to open the liquid line solenoid valve and allow the refrigerant to flow into the condenser. Once the refrigerant has entered the condenser, you can close the liquid line solenoid valve.

There are a few ways to start a refrigeration system. One way is to use a motor starter, which will start the compressor motor and get the system running. Another way is to use an air-handler or furnace with an electric heating element to heat up the evaporator coil and start the refrigeration cycle that way. Finally, some systems have a built-in starting sequence that can be activated by pushing a button on the control panel.
