B213 吸収冷凍機における高効率吸収器の開発

Abstract

Pre-cooling venturi type absorber for absorption heat pump was experimentally investigated to increase vapor absorption rates. In this research, the absorbent is pre-cooled at 35-45℃ before the nozzle, and we examine how much the lithium bromide aqueous solution can absorb the vapor by the proposed venturi type absorption rate of the solution increases as the inlet pressure increases. The ratio of the absorption rate to the flow rate of the absorbent is about 3-5%.
