EXERGY ANALYSIS OF TWO-STAGE WATER TO WATER HEAT PUMP
Апстракт
The paper presents an exergy analysis of the selected two-stage compression water to
water heat pump system in heating mode of operation. The foreseen heat source is underground
water of constant temperature level. The characteristic exergy values are calculated for the ambient
temperature 0 [oC] and ambient pressure 100 kPa. In addition, values of exergy losses, exergy
efficiency, exergy loss ratio, exergy loss coefficient and exergy effectiveness (degree of
thermodynamic ideality) are also calculated and analyzed. The objective to indicate components
and working conditions with increased exergy losses was fulfilled and the obtained results should
provide guidance for design and optimization of heat pumps that operate with underground water
and are used for water heating applications.
