Summary

THE HYBRID HEAT PUMP IS A COMPRESSOR HEAT PUMP WHICH RUNS ON A NON-AZEOTROPIC MIXTURE AS THE WORKING MEDIUM. THEREFORE IT IS EASIER TO ADAPT IT TO THE TEMPERATURE GRADIENT OF EXTERNAL FLUID CURRENTS THAN TO THE COMPRESSOR HEAT PUMP USING TRADITIONAL WORKING FLUIDS. THIS STUDY, BASED ON THE WOR LORENTZ, GIVES AN ACCOUNT OF THE GENERAL THEORY OF THE PERFECT THERMODYNAMICMACHINE, A GENERAL DEFINITION OF THE LORENTZ CYCLE, AND SOME INDIVIDUAL APPLICATIONS. UNDER CONDITIONS WITH EXTERNAL MEDIA HAVING A TEMPERATURE GRADIENT, THE CARNOT CYCLE MAY RESULT IN A SUBSTANTIALLY WORSE PERFORMANCE THA E LORENTZ CYCLE. THIS EXPLAINS WHY, IN THIS CASE COMPRESSOR HEAT PUMPS WHICH OPERATE WITH A TRADITIONAL WORKING MEDIUM ARE INEFFECTIVE. THE PAPER STUDIES THE EFFORTS WHICH STRIVE AT A CLOSER APPROXIMATION OF THE LORENTZ CYCLE, WHICH LEADS TO THE HYBRID HEAT PUMP.
