Abstract : In this experiment we work to measure the heat transfer rate and we saw that the measured heat transfer rate is determined from either direct measurement of the electrical circuit or by measurement of the mass flow rate and the enthalpy change across the evaporator.

We see that the air condition unit can be used to demonstrate a number of important principles in the control of the environment for human comfort industrial and other purposes.

The mains water supply should be connected and the stop cock turned on before the water heaters are switched on even if there is water in the boiler. Check by manually tapping ball valve.

With ambient conditions showing high RH and the refrigerant unit in operation, the air passing through the system can be cooled to below its dew point temperature to precipitate some of its moisture onto the fins of the evaporator.
