IIR documentSummary
A HORIZONTAL MULTISTAGE HEAT PUMP IS PROPOSED AS AN EFFICIENT DESIGN WHENEVER THE REFRIGERANT FLOW RATE THROUGH THE CONDENSER OR THE EVAPORATOR IS SUBJECTED TO A WIDE TEMPERATURE VARIATION. A METHOD OPTIMIZING THIS DESIGN IS DESCRIBED AND THE NOTION OF THE SWITCHOVER TEMPERATURE IS INTRODUCED. FROM THIS TEMPERATURE, THE HEAT PUMP HAS TO BE REPLACED BY DIRECT HEATING. THE APPLICATION OF THIS METHOD TO A FOUR-STAGE HEAT PUMP FOR MALT KILNING IS DESCRIBED. THE COP IS 4.35 WHICH IS HIGHER THAN THE COP OF THE LORENZ CYCLE FOR THE SAME DUTY.
