Heat transfer and energy efficiency of working fluids in mechanical refrigeration.

Prenos toplote i energetska efikasnost radnih fluida u rashladnim uredajima sa mehanickom kompresijom.

Author(s) : CAVALLINI A.

Summary

The heat transfer performance of the working fluid, both in the evaporator and in the condenser, plays an important role in the energy efficiency of vapour compression refrigerating equipment and heat pumps. With respect to condensation heat transfer inside plain tubes, this paper shows how a penalty factor can be associated with any refrigerant as an immediate evaluation criterion of its potential heat transfer performance in condensers. A ranking of the different working fluids in this respect can be established. Furthermore, the manner in which the penalty factor can be used for the optimization of condenser circuitry under specified design constraints is shown.
