A COMPARISON OF 2 MODELS SIMULATING TRANSIENT HEAT TRANSFER IN A WATER SOURCE GROUND COUPLED HEAT PUMP.

Author(s) : MOUJAES S. F.

Summary

A NUMERICAL STUDY IS PERFORMED TO COMPARE 2 MODELS WHICH SIMULATE THE PERFORMANCE OF THE WATER LOOP OF A WATER SOURCE GROUND COUPLED HEAT PUMP. THE FIRST MODEL CONSIDERS THE CONVECTION AND CONDUCTION OF HEAT ALONG THE WATER LOOP AND SOIL RESPECTIVELY WHILE THE SECONDMODEL ADDS THE EFFECT OF THE THERMAL STORAGE OF HEAT IN THE WATER. ALTHOUGH THE MODELS WERE RUN FOR 24 HOURS IN REAL TIME ONLY THE SELECTED MODEL WOULD HAVE TO BE RUN FOR SEVERAL DAYS TO SELECT THE APPROPRIATE LOOP LENGTH FOR A GIVEN HEAT LOADING AND DESIGN CRITERIA. IT WAS CONCLUDED THAT THE USE OF THE MODEL WITH THERMAL STORAGE FOR THE SYSTEM WOULD BE MORE APPROPRIATE IN THE LONG RUN ALTHOUGH MORE COMPUTATION TIME IS DEMANDED AT EACH TIME STEP.
