Summary

Thermodynamic performances of a variety of fluids circulating in ideal heat-pump cycles were evaluated by using the Iwai-Margerum-Lu equation of state. The evaluations were implemented at two operating conditions (evaporating temperatures from 50 to 70 deg C and condensing temperatures from 80 to 140 deg C). The results showed the normal boiling point and the critical pressure of compounds to be the key properties for selecting the thermodynamically proper working fluids. Several potential non-CFC compounds were suggested for the heat pumps with respect to each application.
