NT-87-17-3 — Exergy Analysis of Heat Pumps
- Comments Off on NT-87-17-3 — Exergy Analysis of Heat Pumps
- ASHRAE
The HPSIM computer program for modeling heat pumps (Domanski and Didion 1983) has been augmented to include exergy analysis. Exergy transports between the components, to the loads, and to the environment are evaluated. The exergy consumptions in each component are also determined, as well as each type of consumption in the heat exchangers. Typical results are presented for the operation of a nominal 3.5 ton residential air-to-air heat pump, in both the cooling and heating modes, at four loads. Among the conclusions drawn for this particular heat pump, it is predicted that overall economy would be improved by increasing the heat transfer surface of the indoor coil, say at the expense of outdoor coil surface.
