INFLUENCE OF A SURFACTANT ADDITIVE ON ABSORPTION HEAT PUMP PERFORMANCE.

Author(s) : MICHEL J. W., PEREZ BLANCO H.

Summary

AN ENHANCEMENT OF BOILING HEAT TRANSFER COEFFICIENTS CAN BE OBTAINED BY A PROPER CHOICE OF SURFACTANT ADDITIVES. WHEN THE CAPACITY OF AN ABSORPTION HEAT PUMP IS LIMITED BY ITS GENERATOR CAPACITY AND THE GENERATOR IS OF THE BOILING-POOL TYPE, IT IS POSSIBLE TO INCREASE THE MACHINE CAPACITY BY MEANS OF SURFACTANT ADDITION. IN THE PAPER, THE PRELIMINARY EXPERIMENTS LEADING TO THE SELECTION OF A SURFACTANT FOR A WATER-LITHIUM BROMIDE ABSORPTION HEAT PUMP ARE DESCRIBED. MINIMUM FOAMING WAS THE MOST IMPORTANT CONSIDERATION IN THIS SELECTION PROCESS. THE MEASURED MACHINE PERFORMANCE SHOWS THAT THE GENERATOR CAPACITY MAY BE INCREASED BY VALUES RANGING FROM 5 TO 10% OF THE ORIGINAL CAPACITY.
