Discussion on development of heat pump definition and improvement of an exergy efficiency formula |
| |
| Abstract: | The concept of heat pump in thermodynamics differs from that in engineering. From the definition by the thermodynamics, it can be deducted that the exergy efficiency may be larger than one. Puts forward a new heat pump exergy efficiency formula according to the basis of exergy efficiency and introduces the exergy efficiency, supply exergy coefficient, exergy loss coefficient, exergy loss ratio into the exergy analysis of heat pumps. |
