ShareInfluence of heat-exchanger size and augmentation on performance potential of mixtures in air-to-air heat pumps.
Author(s) : RICE C. K.
Summary
A modified Carnot analysis with finite heat exchanger (HX) sizes, counterflow HX configurations, and ideal glide matching was conducted for an air-to-air heat pump application. The purpose of the analysis was to determine potential HX size and refrigerant-side augmentation benefits for ideal mixtures, relative to pure refrigerant alternatives. Maximum possible COP gains for refrigerant mixtures were evaluated for four steady-state conditions. Performance improvement opportunities were found primarily in the cooling mode.
