Generally, the heat transportation for a long distance is necessary to use the waste heat effectively. The purpose of the study is to evaluate the performance of heat energy transportation using Solution Transportation Absorption cycle: STA analytically and experimentally. The STA system is based on the principle of the absorption cycle. The absorption cycle consists of 4 heat exchangers; generator, condenser, absorber and evaporator. The STA system has generator and condenser on the heat supply side while absorber and evaporator on the heat demand side. The solution is transferred between heat supply side and demand side, which works as a medium of heat energy transportation. Since heat energy is converted into the concentration difference of the solution. This paper discussed the mathematical analysis of the STA system when it was used for the hot water provision and the comparison STA system between conventional systems. The results of the simulation of the STA system show that COP decreases when the ambient temperature decreases. And, the results of the comparison show that the STA system has smaller inside diameter of pipeline, much longer transportation distance, and better efficiency of transportation than conventional systems.
