Split solid adsorption cooling system

Abstract

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.

1 . A split solid adsorption cooling system, comprising:
 a first adsorption unit comprising a first vacuum chamber, a first adsorption bed, and a first condenser, wherein the first adsorption bed and the first condenser are provided in the first vacuum chamber, the first adsorption bed comprising a first water inlet and a first water outlet, the first condenser comprising a first refrigerant inlet and a first refrigerant outlet;   a second adsorption unit comprising a second vacuum chamber, a second adsorption bed, and a second condenser, wherein the second adsorption bed and the second condenser are provided in the second vacuum chamber, the second adsorption bed comprising a second water inlet and a second water outlet, the second condenser comprising a second refrigerant inlet and a second refrigerant outlet; and   a shell-and-tube heat exchanger comprising:   a shell comprising an ice water inlet and an ice water outlet;   at least a first pipeline having a first end and a second end, wherein the first end is connected to the first refrigerant outlet via a first valve unit, and the second end is connected to the second refrigerant inlet via a second valve unit; and   at least a second pipeline having a third end and a fourth end, wherein the third end is connected to the second refrigerant outlet via a third valve unit, and the fourth end is connected to the first refrigerant inlet via a fourth valve unit.
