Page 3: Working Principle
I. Working principle The water dispenser is a kind of device, which provides bottled drinking water (distilled water, pure water, mineral water, etc.) or daily life water treated through purification equipment to people for drinking, after being heated, cooled or at its original water temperature. Diversion and shunt functions: through the effect of atmospheric pressure, guide 3 gallons or 5 gallons of commercial water contained in a large bottle, through the bottle supporter, into their tanks respectively, to realize the purpose of auto provision and supplementation of water. -

Page 8: Attachment 3 Compressor Working Principle And Failure Analysis
Attachment 3 Compressor Working Principle and Failure Analysis Brief outline of compressor cooling working principle The water dispenser compressor cooling system mainly includes compressor, condenser, filter, evaporator, capillary and other components. Drying filter Capillary Evaporator Condenser Compressor The water dispenser adopts a rotary compressor filled with cool-producing medium R134a. R134a gas is, by the compressor, compressed into high-pressure gas, goes into the condenser and then becomes high-pressure liquid. - Page 9 I. Methods for Compressor Maintenance The single hermetic compressor has three terminals on the body: R•primary coil or moving coil S•starting coil C•public poin Judgment of compressor exhaust pipe oil vent Generally, little oil discharges from a hermetic compressor. If oil is found to drip from the exhaust pipe continuously, it is shown that the compressor is discharging too much oil.
