Summary
Herein the results of operating a frozen air heat exchanger within a monovalent heat pump system (air/water) controlled by a micro-computer are presented. We will be reporting about the operation of a micro-computer control, which allows the adjustment of any superheating temperature of the suction gas and a over all optimization. The most important parameters of the optimization of the evaporator operation were the fan operation/air flow rate and the whole defrosting procedure.
The various air flow rates (adjusted by varying the r. p. m. of the fan), have only little importance to the coefficient of performance. But a new criterion tested in practical operation for initiating the defrost procedure by using a calculated/estimated heat transfer coefficient is presented.
