Refrigerating system

The utility model provides a refrigerating system, and belongs to the refrigerating technical field. The refrigerating system solves the problem that an existing refrigerating system is high in production cost and inconvenient to install, and wastes energy. The refrigerating system comprises a box body, an exchanging pipe and a water tank arranged at the lower portion of the box body. The exchanging pipe penetrates through the box body and is sealed with the box body, and two ends of the exchanging pipe are communicated to form an annular loop. A plurality of adsorption and desorption pipes are arranged in the box body, one ends of the adsorption and desorption pipes are sealing ends, and the other ends of the adsorption and desorption pipes are communicated with the exchanging pipe. A smoke inlet for outside exhaust smoke to enter is formed in the side portion of the box body, and a smoke outlet is formed at the upper portion of the box body. A water supply structure for water in the water tank to enter the
