Abstract
Environmental awareness is increased and heat pump systems have become more common because of several reasons such as; the depletion of fossil fuels and environmental harm caused by the fossil fueled air-conditioning systems. Heat pumps can be air source, waterborne, ground source due to the ambient that they transfer or reject heat. Water is the most efficient way to transfer heat in comparison to other resources. Considering cooling systems, waterborne systems are more efficient and smaller than air source systems. As it is known, air temperature is very high in the Mediterranean region hence COP (coefficient of performance) of air source heat pumps decrease. This study carries out the energy analysis of a heat pump which transfers the heat between cooled space and hot water tank. The waterborne air pump is installed in the Thermodynamics Laboratory of Engineering Faculty of Akdeniz University and the energy analysis of both cooling system and hot water supply is performed based on various parameters for a sample day. Mean water heating, space cooling and overall COP are calculated as 2.61, 2.08 and 4.69, respectively.
