DYNAMIC MODELLING OF A RESIDENTIAL HEAT PUMP FROM ACTUAL SYSTEM PERFORMANCE DATA.

Author(s) : CRAWFORD R. R., SHIREY D. B.

Summary

OPTIMAL HEATING AND COOLING CONTROL STRATEGIES FOR HEAT PUMPS REQUIRE A DYNAMIC MODEL FOR PREDICTING THE PERFORMANCE CHARACTERISTICS OF THE OVERALL SYSTEM. A MODELING PROCEDURE HAS BEEN DEVELOPED THAT CAN PREDICT THE INDOOR TEMPERATURE AS A FUNCTION OF AMBIENT WEATHER CONDITIONS AND HEAT PUMP ELECTRICAL CONSUMPTION. THIS PROCEDURE RESULTS IN A RATIONAL, DISCRETE-TIME, MODEL WHICH IS DIRECTLY DERIVED FROM ACTUAL PERFORMANCE DATA FROM A SINGLE-FAMILY RESIDENCE USING AUTOREGRESSIVE LEAST SQUARES TECHNIQUES. THE RESULTING MODEL IS ESPECIALLY USEFUL FOR HEAT PUMP SYSTEM ANALYSIS SINCE IT ALSO PROVIDES QUANTITATIVE PREDICTIONS OF HEAT PUMP CAPACITY AND COP AS A FUNCTION OF OUTSIDE TEMPERATURE.
