Heat Pump evaporators - A-state-of-the-Art Report

Report, 1989

This volume contains the final report of lEA Advanced Heat Pumps, Annex VII: "New Development of The Evaporator Part of Heat Pump Systems". The objectives of this Annex have been: To collect and evaluate existing theoretical and experimental information for the evaporator part of heat pump systems. Types of evaporators included have been equipment for both liquid and gaseous heat sources used in direct as well as indirect systems. The work has been divided between the Operating Agent (Sweden) and the National Teams of Canada, Denmark, Finland, Norway, and Sweden. The major part of the work has been to collect information on various aspects of the evaporator part, both from the literature and from the National Teams. The result of the work is this report which contains the following chapters: 1. INTRODUCTION 2. HEAT PUMP EVAPORATOR TYPES 3. HEAT TRANSFER AND PRESSURE DROP ON HEAT SOURCE SIDE OF HEAT PUMP EVAPORATORS 4. HEAT TRANSFER AND PRESSURE DROP ON REFRIGERANT SIDE OF HEAT PUMP EVAPORATORS 5. OPTIMIZATION OF HEAT PUMP EVAPORATORS 6. RESEARCH AND DEVELOPMENT TRENDS IN THE PARTICIPATING COUNTRIES
