| 20120006049 | SPLIT SOLID ADSORPTION COOLING SYSTEM - A split solid adsorption cooling system is disclosed. The split solid adsorption cooling system includes a first adsorption unit, a second adsorption unit, and a shell-and-tube heat exchanger. The first and the second adsorption units are connected to each other via a first pipeline and a second pipeline of the shell-and-tube heat exchanger. While adsorption and desorption take place alternately in the first and the second adsorption units, the temperature of the first and the second pipelines is lowered, thereby decreasing the temperature of water flowing in the shell-and-tube heat exchanger. In addition, the manufacturing costs of the split solid adsorption cooling system can be lowered because the shell-and-tube heat exchanger need not be operated in a vacuum environment. Furthermore, as the shell-and-tube heat exchanger is separate from the first and the second adsorption units, the overall system volume is reduced. | 01-12-2012 |
