THE INFLUENCE OF CONDITIONS ON THE PERFORMANCE OF SMALL HEAT PUMPS.

[In Finnish. / En finnois.]

Author(s) : WIKSTEN R.

Type of article: Periodical article

Summary

EXAMINES THE RESULTS OF FIELD MEASUREMENTS OF SMALL HEAT PUMPS WHEN CONDITIONS DIFFER FROM THOSE MEASURED IN THE LABORATORY. MEASUREMENTS INDICATE THAT CHANGES IN FLUID FLOW TO THE EVAPORATOR DO NOT AFFECT THE COP, BUT DO AFFECT THE HEAT OUTPUT FROM THE CONDENSER. CALCULATES THE ANNUAL COP BASED ON LABORATORY MEASUREMENTS FOR A GROUND HEAT PUMP AND AN AIR TO AIR HEAT PUMP. STATES THAT THE ANNUAL COP FOR AN AIR TO AIR HEAT PUMP CAN BE CALCULATED WITH THE AID OF THE BUILDING HEAT DEMAND, THE CORRESPONDING OUTDOOR TEMPERATURE AND THE ENERGY FLOWS OF THE HEAT PUMP MEASURED IN STEADY STATE CONDITIONS.
