シリカゲル/FAM Z01を用いた凝縮熱による二重効用吸着冷凍サイクルの性能解析

抄録

A numerical investigation of double effect adsorption refrigeration cycle using Silica-gel/FAM-Z01 pair as adsorbent is studied in this paper. The proposed cycle is based on the cascading adsorption cycle, where condensation heat produced in the top cycle is utilized as driving heat source for the bottom cycle. Results show that this cycle produces higher COP and SCP compared to Silica-gel/Silica-gel double effect cycle for driving temperature observed between 90ºC and 150ºC, when cycle averaged chilled water temperature is fixed at 10ºC. Moreover, between 130ºC and 150ºC, COP take the maximum value when cycle time range from 1100s until 1300s. It is also observed that adsorbent mass ratio of high temperature cycle (HTC) to low temperature cycle (LTC) affects the double effect performance adsorption refrigeration cycle.
