The technical solution adopted in the present invention is, a kind of closed evaporation cooling high-temperature handpiece Water Chilling Units, comprise the evaporative cooling coil pipe, the top of evaporative cooling coil pipe, be disposed with filler I from the bottom up, water-locator I, water fender I and blower fan, be respectively arranged with one group of tube type indirect evaporative cooler outside the both sides of evaporative cooling coil pipe bottom, tube type indirect evaporative cooler is made up of the many tube type indirect evaporative cooler heat exchanger tubes that vertically are provided with side by side, the top of every group of tube type indirect evaporative cooler, be disposed with filler II from the bottom up, water-locator II and water fender II, be respectively arranged with open tank II below every group of tube type indirect evaporative cooler, be provided with open tank I below the evaporative cooling coil pipe, open tank II is separated by barrier mutually with open tank I, open tank II is connected with water-locator II by pipeline, this pipeline is provided with water pump I, open tank I is connected with water-locator I by pipeline, and this pipeline is provided with water pump II.
Characteristics of the present invention also are,
Be provided with dividing plate between the filler II of evaporative cooling coil pipe and its both sides, water-locator II and the water fender II.
The top of barrier is elongated to mutually concordant with the bottom of tube type indirect evaporative cooler at least.
Compare with traditional mechanical refrigeration high-temperature handpiece Water Chilling Units and open type evaporation cooling high-temperature handpiece Water Chilling Units, closed evaporation cooling high-temperature handpiece Water Chilling Units of the present invention has following characteristics:
1) adopting the pipe type heat transfer pipe to erect is provided with, walk primary air outside the pipe, spray recirculated water in the pipe, the tube type indirect evaporative cooler of walking auxiliary air carries out first precooling to air, pre-cold efficiency height, avoided because of the Northwest's dust storm, dust are big, adopted surface cooler and the plate fin type indirect evaporative cooler precooling results in blockage or the generation of scale formation.
2) air dry-bulb temperature after the tube type indirect evaporative cooler precooling and corresponding wet-bulb temperature are lower, again through with the evaporative cooling coil pipe outside shower water carry out that water carries out heat exchange in heat wet exchange back and the evaporative cooling coil pipe, the cold water water temperature of producing is between outside air dew-point temperature and wet-bulb temperature, can satisfy the water temperature requirement of dry type or dry cooling condition sensible heat end, and avoided the generation of the terminal dewfall phenomenon of sensible heat, meet the water temperature requirement of NORTHWEST CHINA area evaporative cooling half central air-conditioning system, have better energy saving and practicality.
3) adopt the evaporative cooling coil pipe, shower water carries out with the primary air of precooling outside the evaporative cooling coil pipe that heat is wet to be exchanged, carry out heat exchange by the interior water of tube wall and pipe again, the high temperature cold water that the evaporative cooling coil pipe offers evaporative cooling half central air-conditioning system is a closed Water System, overcome the Northwest's dust storm, characteristics that dust is big, recirculated water is vulnerable to pollution not, and the corrosion of piping degree is light, the geography and climate characteristics that meet the dry area of NORTHWEST CHINA, having stronger is application.
4) adopt closed Water System, evaporative cooling half central air-conditioning system pump head is low, only need overcome the resistance of closed Water System loop, and is irrelevant with depth of building, carries power consumption little, more energy-conservation.And need not establish back pool, the machine room floor space is little.
5) open tank that adopts branch to be arranged, tube type indirect evaporative cooler pre-cooler open tank, circulating water device, water-distributing device and evaporative cooling coil pipe open tank, circulating water device, water-distributing device branch are arranged, and it is separate, avoided because tube type indirect evaporative cooler spray recirculated water is different with evaporative cooling coil pipe spray recirculated water water temperature, the two mixes mutually, influences the water temperature of high temperature cold water.
