A Comparative Study of Vapour Compression Heat Pump Systems under Air to Air and Air to Water Mode
Authors: Kemal Çomakli, Uğur Çakir
Abstract:
This research evaluated and compared the thermodynamic performance of heat pump systems which can be run under two different modes as air to air and air to water by using only one compressor. To achieve this comparison an experimental performance study was made on a traditional vapor compressed heat pump system that can be run air to air mode and air to water mode by help of a valve. The experiments made under different thermal conditions. Thermodynamic performance of the systems are presented and compared with each other for different working conditions.
