Abstract

The paper presents the comparative exergetic analysis of different heat pump designs from an energy con sumption point of view. Heat pumps are usually classified according to the environment from which they extract heat in order to help the consumer in choosing a heat pump type, based on the available heat sources. From the construction point of view, a wide variety of heat pumps have appeared as a result of the various heat sources to be considered, and the refrigerants used. Also, due to the desire to improve their operation, various constructive variants have been developed. Considering that all heat pumps use electricity to oper ate, their energy consumption for producing the same thermal effect should be a criterion for their choice, along with economic aspects.
