EXPERIMENTALLY DERIVED ENERGETISTIC EFFICIENCY OF A SMALL HEAT PUMP IN A TECHNICAL AND ECONOMIC ASPECT.

Author(s) : SUKIENNIK M. A.

Summary

THE ARTICLE DESCRIBES THE MODEL AND DEVELOPMENT METHOD OF A WATER-AIR HEAT PUMP PRODUCING HOT WATER. THE FOLLOWING WAS OBTAINED: REAL EFFICIENCY OF THE HEAT PUMP IS RELATED TO HOT WATER TEMPERATURE, WARM WATER FLOW, REFRIGERANT FILLING AND THE SEASON OF THE YEAR ; THE RELATIONSHIP OF WARM WATER FLOW TO WATER TEMPERATURE AND THE CHARACTERISTICS OF HEATING WATER WITHOUT WARM WATER CONSUMPTION. TECHNICAL AND ECONOMIC ASPECTS ARE SHOWN TO FAVOR THIS TYPE OF HEAT PUMP OVER AN ELECTRIC WATER HEATER. HEAT PUMP REAL EFFICIENCY IS SHOWN TO BE INCREASED BY THE FOLLOWING: VARYING HOT WATER TEMPERATURE ACCORDING TO DEMAND, UTILIZING HEAT LOSSES THROUGH THE COMPRESSOR BOWL AND OPTIMIZING THE AMOUNT OF REFRIGERANT FILLING OF THE SYSTEM. PUMP EFFICIENCY IS INCREASED BY 30-34%.
