Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

Q2. The majority of houses in İzmir is equipped with air-conditioners for keeping the inside temperature of houses at comfortable levels during hot summer days. Consider a hot summer day, the outdoor temperature is 42 °C, an air-conditioner runs to keep a room at 22 °C. The room is not well-insulated and therefore absorbs heat through its walls at a rate of 400 kJ/min. There are also electronic equipments in the room generating 600 W of heat. The cooling fluid inside the air-conditioner, DuPont Freon 12 enters into the compressor as a saturated vapor at 362 kPa and leaves it at 1000 kPa and 60 °C. The fluid flow rate through the compressor is 6000 L/h. а. What is the actual coefficient of performance of the air-conditioner? b. What is the minimum power input to the compressor for the same refrigeration process.
