PERFORMANCE MONITORING OF AN ADSORPTION HEAT PUMP: MODEL DEVELOPMENT AND SIMULATION STUDIES.

Author(s) : MEUNIER F., ZANIFE T.

Summary

PERFORMANCE MONITORING OF AN ADSORPTION HEAT PUMP HAS BEEN STUDIED IN A CASE OF HOT WATER DELIVERY TO A SLAUGHTERHOUSE WHEN HEAT DEMAND IS A VERY IRREGULAR FUNCTION OF TIME. AS THE HEAT DELIVERED BY AN ADSORPTION HEAT PUMP IS DISCONTINUOUS, A HEAT STORAGE TANK HAS BEEN USED. THE INFLUENCE OF THE HEAT TRANSFER FLUID MASS FLOW RATE IN THE HEAT PUMP IS VERY IMPORTANT BECAUSE: A LOW MASS FLOW RATE YIELDS A HIGH TEMPERATURE LIFT BUT A LOW EFFICIENCY ; A HIGH MASS FLOW RATE PRODUCES INSTABILITIES ON THE CONDENSER AND YIELDS A LOW EFFICIENCY ; AND AN INTERMEDIATE MASS FLOW RATE YIELDS A REASONABLE EFFICIENCY AND A CORRECT TEMPERATURE LIFT. NEVERTHELESS, AFTER A VERY LARGE PEAK DEMAND, THE TEMPERATURE REQUIREMENT IS NOT SATISFIED AND A 7 % DISSATISFACTION OF THE NEEDS IS OBTAINED. TO GET 100 % SATISFACTION, IT WOULD PROBABLY BE NECESSARY TO OVERDESIGN THE HEAT PUMP AND THE BOILER.
