Abstract
The Solution Transportation Absorption chiller (STA) can transport the thermal energy at ambient temperature due to conversion of the thermal energy into concentration difference of the refrigerant and the solutions. This study, on the assumption that a large scale STA as the heat transportation distance is 10000 m and the cooling output is 3517 kW, simulates the dynamic behaviors decreased to 20 % of the cooling output and then analyze the effect of control ability and the refrigerant receiver on the transport pipe. The behaviors of the cooling output are almost the same tracking as those of both 1 m and 10000 m pipes. Lager volume of the pipe will results in more use of refrigerant in the refrigerant receiver because the increased amount of refrigerant mass in the strong solution is used by refrigerant in the refrigerant receiver. Therefore, STA can be controlled for the cooling output by the conventional control method. On the other hand, the receivers volume or filling amount of the refrigerant are required to be designed according to the pipe volume.
