EFFECT OF CYCLING AND FROST FORMATION ON HEAT PUMP PERFORMANCE. IMPLICATIONS OF CYCLIC TEST DATA.

Summary

REPRESENTATIVE DATA WERE ANALYZED TO DETERMINE THE EXPECTED IMPACT OF FROSTING/DEFROSTING AND CYCLING ON THE HEATING SEASONAL PERFORMANCE FACTOR. THE STUDY IS MADE BY COMPUTATION, NEGLECTING THE CYCLIC LOSSES AND/OR THE LOSSES BECAUSE OF FROSTING/DEFROSTING. THE EFFECTS OF NEGLECTING FROSTING/DEFROSTING ARE NOTED TO BE QUITE SMALL, LESS THAN WHAT WOULD BE EXPECTED BASED ON THE LIMITED FIELD DATA AVAILABLE IN THE LITERATURE. THE LOSSES DUE TO CYCLING EFFECTS ARE ALSO NOTED TO BE SOMEWHAT LOWER THAN EXPECTED, BUT IN AGREEMENT WITH THE ESTIMATES OF LOSSES BASED ON OTHER FIELD DATA.
