Principle of refrigeration system and electric circuit diagram:
The principle of compression refrigeration consists of "compression", "condensation", "throttling" and
"vaporization".
Compression is performed by the compressor, condensation is performed by the condenser, the throttling
valve is performed by the capillary and vaporization is performed by the evaporator.
When the refrigerant is circulating in the closed refrigeration system, the compressor sucks the refrigerant,
which has absorbed the evaporator, the refrigerant becomes a high pressure and high temperature gas.
The liquefied refrigerant boils rapidly and vaporizes into gas when the pressures drop suddenly.
Meanwhile,it absorbs the heat inside the refrigerator. And the compressor sucks in the low pressure and
low temperature gaseous refrigerant, :--*:*-- circulates in this direction until the realization of the intended
refrigeration.

The following phenomena are not a problem
The murmur of water is heard when the
refrigerator is running. This is a normal
phenomenon as the refrigerant circulates in the
system.
In the rainy season, there may be condensation
on the outside of the refrigerator, but it is not a
problem caused by high humidity. Simply use a
cloth to wipe it off.
NOTE:
Maintenance:
1. Warning
Keep the refrigerator clean often and perform regular maintenance. Always unplug the power plug before
servicing.
Never use a damaged plug or a loose outlet to avoid electric shock or short circuit. Never use detergent,
soap, gasoline, acetone or a brush.
2. Clean the exterior
Dip a soft cloth in neutral detergent (dish detergent) to clean the exterior of the refrigerator and then wipe
it with a dry soft cloth.
3. Cleaning the inside
Remove the rack to clean it with water. Use a soft cloth to wipe the case.
4. Turn off the refrigerator for a long time
Remove all food and unplug the power plug. Clean the inside and outside of the refrigerator thoroughly
and open the door to dry it thoroughly. Glass shatters easily. Keep glass away from children.
