Principle of Refrigeration System

The principle of compression refrigeration consists of “compression” , “condensation ” , •·throttling” and “vaporization” . The compression is undertaken by compressor, the condensation is completed by condenser, the throttling valve is executed by capillary and the vaporization is implemented by evaporator. When the coolant is circulating in the closed refrigeration system, the compressor sucks coolant, which has absorbs heat in evaporator, the coolant becomes a high pressure and high temperature gas. In condenser, ii dissipates heat in air, while the coolant is re- liquefied and throttled in capillary and then enters into evaporator with low pressure. The liquefied coolant quickly boils and vaporizes into gas when the pressure suddenly drops. Meanwhile, it absorbs heat inside the refrigerator. And the compressor sucks the low pressure and low temperature gaseous coolant, ……… _lt is circulating in this way up to realization of intended refrigeration.

Circuit Diagram

Maintenance

1. Notice

   • Often keep the refrigerator clean and periodical maintenance is necessary.
   • Always unplug the socket before maintenance.
   • Never use damaged plug or loose socket to prevent from electric shock or short circuit.
   • Never flush the refrigerator.Never use alkali detergent,soap,gasoline,acetone or brush.

2. Clean outside
   Dip soft cloth in neutral detergent(tableware detergent)to clean the outside of the refrigerator and then wipe it with dry soft cloth.

3. Clean inside

   • Take rack out for cleaning with water.
   • Use soft cloth to wipe the box.

4. Shut down refrigerator for a long time
