Vapor Compression Heat Pump Cycle With Desorber/Absorber Heat Exchange

Published

Author(s)

R Radermacher

Abstract

In this paper, a special version of a vapor compression heat pump cycle with solution circuit is introduced. In this cycle, the gliding temperature intervals are deliberately chosen so large, that the highest temperature in the desorber (evaporator) is higher than the lowest temperature in the absorber (condenser). As a consequence, part of the absorber will be supplying heat to the desorber resulting into an extremely low pressure difference across the compressor, however, increasing the mass flow rate for a given capacity. Depending on the application, significant increases in the coefficient of performance are available while pressure ratios stay below 2 for all applications discussed here.
