A table top air conditioning system is used to demonstrate how heat is transferred from air to water.

A water cooled heat exchanger is used as a condenser while the liquid refrigerant is evaporated in an air cooled evaporator. Instruments are provided for measurement of temperatures, pressures, and water flow rate. The system requires outside water supply.

Instruction manual is also included.
