The objective of this paper is to evaluate the performance of absorption heat pump systems for heat transportation at ambient temperature without any insulation. Absorption heat pump consists of four main components: an evaporator, an absorber, a generator, a condenser. The components of conventional systems are located all together at the heat supply side. The heat is transferred by the sensible heat. In the STA system, however, heat is transferred by the concentration difference of the absorption solution by locating the absorber and the evaporator at the heat demand side and the condenser and the generator at the supply side. The cycle simulation results show that charge quantity for the generator of the STA system increases more than that of the conventional system. Therefore, the COP declines. On the other hand, the highest temperature in the absorber of STA is as high as the temperature of conventional. In addition, this paper shows the performance of new STA systems which produce chilled and hot water simultaneously.
