MATHEMATICAL MODELLING OF A DIRECT EXPANSION GROUND-COUPLED HEAT PUMP SYSTEM.

Author(s) : SAFEMAZANDARANI P.

Summary

THE SIMULATION TOOL IS A FORTRAN COMPUTERPROGRAM THAT PREDICTS THE TRANSIENT PERFORMANCE OF A HEAT PUMP IN WHICH EITHER THE CONDENSER OR THE EVAPORATOR IS A GROUND-LOOP HEAT EXCHANGER CONCENTRATOR. THE PERFORMANCE OF THE CONVENTIONAL INDOOR COMPONENTS OF THE SYSTEM IS SIMULATEDWITH A HEAT PUMP PROGRAM. THERMAL ANALYSIS INVOLVES THE TRANSIENT CONDUCTION IN THE EARTH, HEAT TRANSFER IN THE GROUND LOOP, AND COMPONENT PERFORMANCE. THE STEADY-STATE PROGRAM HAD TO BE MODIFIED TO ACCOMMODATE THE TRANSIENT BEHAVIOUR.
