A THEORETICAL AND EXPERIMENTAL ANALYSIS OF DOUBLE-SPIRAL, DOUBLE-WALL HEAT EXCHANGERS.

Author(s) : MEI V. C., FARMER J. T.

Summary

A NOVEL DESIGN FOR A DOUBLE-SPIRAL-COIL COUNTERFLOW HEAT EXCHANGER, WHICH SATISFIES THE REQUIREMENT FOR A DOUBLE WALL BETWEEN THE FLUIDS FOR HEAT PUMP WATER HEATERS AND SOME SOLAR ENERGY COLLECTING SYSTEMS, WAS BUILT AND TESTED. A MATHEMATICAL MODEL WAS SET UP AND AN EASY-TO-USE CLOSED FORM SOLUTION WAS DERIVED. THE SOLUTION PREDICTED THE EXPERIMENTAL FLUID TEMPERATURE PROFILES WELL, EXCEPT AT VERY LOW FLUID FLOW RATES WHERE THE CALCULATED HEAT EXCHANGER PERFORMANCE BECAME CONSERVATIVE.
