I will design and configure up the
bottle-style water cooler's
evaporator and condenser in my
thesis.

13. About Condenser
A condenser is a heat exchanger used to condense a gaseous substance into a liquid
state through cooling.
13
Theory And Operation Of Condenser
 Transferring heat from the refrigerant to another medium, such air or water, is the
condenser's job in a refrigeration system.
 Inside the condenser, the gaseous refrigerant condenses to liquid by rejecting heat.

16. About Evaporator
The component of the cooling system that absorbs heat and permits the cooling
process to occur is the evaporator in a water cooler.
16
Theory And Operation Of Evaporator
The evaporator in a water cooler is responsible for absorbing heat from the
surrounding environment, cooling the contents of the water cooler in the process.
