          The Principle of Operation

            Refrigerant Circulation

            A refrigerant absorbs heat from the inside of the display case and releases it outside.

            Compression

            The compressor increases the pressure and temperature of the refrigerant gas.

            Condensation

            The refrigerant releases heat and turns into a liquid in the condenser.

            Evaporation

            The refrigerant absorbs heat and turns back into a gas in the evaporator.

            Continuous Cycle

            This cycle repeats to maintain the desired temperature inside the display case.

            Rules of Operation

              Temperature Settings

              Set appropriate temperatures for different types of products to ensure preservation.

              Loading Practices

              Avoid overloading the display case to maintain proper airflow and cooling efficiency.

              Cleaning Schedule

              Regularly clean the interior and exterior to prevent bacterial growth and maintain hygiene.

              Maintenance Checks

              Schedule routine inspections and maintenance to identify and address potential issues promptly.

              Monitoring System

              Monitor temperatures and performance to ensure the unit is operating correctly.

              Safety First!

                Electrical Safety

                Ensure the unit is properly grounded to prevent electrical shocks.
