PERFORMANCE OF DOUBLE EFFECT SOLUTION TRANSPORTATION ABSORPTION CYCLE TO UTILIZE CONDENSATION HEAT OF REFUSE POWER GENERATION

摘要

The authors proposed heat transportation system based on ammonia absorption refrigeration cycle named STA. The idea is to transport ammonia solutions instead of chilled water from heat source side to heat demand side. It can transport thermal energy at ambient temperature because the system converts thermal energy into concentration difference of the solutions. However, because the COP of the ammonia based STA is not high enough, combination of LiBr absorption cycle to enhance the performance was proposed so that the COP could be doubled. The objective of the paper is to investigate the performance of the double effect STA to supply cooling. It was also attempted to apply the double effect STA to refuse power generation to utilize condensation heat to drive STA. The total performance of power generation and cooling supply was discussed in terms of primary energy reduction.
