Résumé

In this paper, heat pump system has been developed by CFD simulation and expermental investigation. It studies the thermal behavior of a thermobank and COP on heat pump system and cold storage. The thermobank stores the wasted heat of during refrigeration cycles and its energy is used for defrosting process and heating room. It also reduces defrosting time and condensation load so that the temperature regulation in the cold storage is constant. The system is investigated experimentally and CFD simulated under thermobank. The dimension L×W×H of cold storage is 3×1,6×1,4 m, thermobank is 600×300×400mm. The temperature of ambient on CFD simulation process is 150C.This heat pump system can be used to keep preservation of agricultural products in cold storage warehouse together with floor panel heating for room in winter. The ejector is used in system which the purpose increases in coefficient of performance (COP) and decrease in compressor displacement. As the calculated results, its COP is increased about 18.57% when using the ejector in heat pump system.
