The invention discloses a
heat pipe type energy-saving central air-conditioning cooling
system. The central air-conditioning cooling
system comprises a
cooling tower and is characterized in that a
heat pipe device is installed in a case of the
cooling tower, cool air inlets are mounted on two sides of the case of the
cooling tower, a hot air outlet is arranged at the top of the case of the cooling
tower, and an induced draft fan is mounted at the hot air outlet; the
heat pipe device is a spiral heat
pipe, a forest-type heat
pipe or a
branch-shaped heat
pipe, the
evaporation section of the heat pipe contacts with a working solution in a
junction box, the cooling section contacts with cool air induced by the cool air inlet, hot air formed by the heat pipe after heat is absorbed by the cool air is discharged out of the cooling
tower through the induced draft fan, and the heat pipe introducing a heat source form a
heat exchanger of a refrigerating unit is connected to the working solution in the
junction box; and a water tray in the cooling
tower is equipped with a circular
sprayer or atomizer, an electric pump is started to enable water in the water tray to be sprayed through the
sprayer or atomized through the atomizer, the water in the water tray is supplied by a
water supply pipe which is connected with a
tap water pipe outside, and the
water volume is controlled by a float valve device. The heat pipe type energy-saving central air-conditioning cooling
system has the advantages of being water-saving, small in occupied building space and silent in operation.
