Heat pipe falling film generator for low grade heat drive absorption refrigeration

Abstract

The invention discloses a heat pipe falling film generator for low grade heat drive absorption refrigeration. The heat pipe falling film generator for low grade heat drive absorption refrigeration comprises a generator shell. A solution outlet, a solution inlet, a hot water inlet, a hot water outlet and a steam outlet are formed in the shell; step disk generation pipes are arranged in the shell, and comprise steam generation disks, heat pipes and water pipes; the water pipes communicate with the hot water inlet and the hot water outlet; the heat pipes are arranged on the water pipes in a penetrating way; the steam generation disks are fixedly connected with the heat pipes; a gap in which fallings films can be produced is remained between each steam generation disk and each water pipe. According to the heat pipe falling film generator for low grade heat drive absorption refrigeration provided by the invention, the performance of low grade heat applied in the solution generation process can be improved, the high efficient utilization of a low temperature heat source is realized, and the thermal performance of the absorption refrigeration cycle is further improved.
