Abstract
The authors have examined heat transportation based on ammonia absorption cycle named STA. STA recovers discharged heat and converts it into cooling. New type of STA was proposed in this study, which incorporates two evaporators to provide cooling at different temperature simultaneously. The objectives of this study are to investigate the static performance such as cooling output and COP as well as to observe the interaction between two refrigeration cycles of the proposed STA by non- steady state simulation. The static cycle simulation reveals that cooling output of each evaporator is proportional to refrigerant mass flow. The result of dynamic simulation shows that the change of cooling load in one side affects the temperature behavior of the other side to some extent. Because the effect seems small, it implies that the two evaporators can be controlled separately as the conventional way.
