Cooling tower Along with
the development of industrial production and improving of people's living
standards, reasonable development and utilization for the water become an
urgent problem waiting to be solved. A lot of units generally adopt the FRP
cooling tower, the ideal equipment of the energy-efficient, to carry out the
closed circulation of inside water. It raises the ratio of utilization and
lower costs of the expenses effectively. At the same time, it make people's
hope of changing the temperature and humidity of environment, clean degree and
that noise influence becoming reality.
The cooling tower is corrosion-resistant, the intensity is high, light, small, attractive and durable occupation of land, transport, and maintenance and install are convenient. So it has been applying to many trades. It is particularly suitable to air conditioner, refrigeration, pigeonhole standing, heating furnace and cold emptily, congealing cooling water circulatory systems.
The round Counter flow type cooling tower adopt the gas &heat exchanges technology and the packing is made of modify high quality PVC wave slice to spread water area; Through rotating the water to realize the even scope and it strengthen the result of cooling. We have maken part improve in the appearance design of this series of products, and it make running reliable, durable, and convenient in fitting.
DBNL4 series of low noise FRP cooling tower is suitable for general places that AC group water temperature-reduce is 3~8 degree,
PERFORMANCE AND CHOICE
A. Design Parameter:
1.Standard operating case: Enter-water temperature T1=37,out-water temperatureT2=32, Designed wet-ball temperature =27instantaneous-water temperature =5,cold width T2-=5
2.mid-temprature case: Enter-water temperature T1=43,out-water temperature T2=33, Designed wet-ball temperature =27, instantaneous-water temperature =10,cold width T2-=6
3.High-temerrature case: Enter-water temperature T1=60,out-water temperature T2=35, designed wet-ball temperature =27, instantaneous-water temperature =25,cold width T2-=8
B. We must know the enter-water temperature t1, out-water temperature t2 and designed wet-ball temperature t, then confirm the type according to the heating power character curve(Attach table 1 and 2) while selecting. We can carry on heating power calculating to the operating case out the curve table. The following if volume quality coefficient of filling :
1.2 times of names flow rate:=18600
1.0 times of names flow rate: =17800
0.8 times of names flow rate:=17000
C. The operating weight should be calculate with the half height of tower-body's water, If calculate according to the height after filling with water that should be multiplied by 1.5.
D. This serial cooling tower is used in the areas which the temperature on average of the coldest month isn't lower than - 10,the user of areas which temperature is much lower than others should propose the request of preventing freezing to dispose the water dispose ring, prevent water pour the shutter. Add the electric heater in water trough during the running disconnectedly in the course of winter.
E. Circulating water turbidity degree can't be higher than 50MG/L and can't be higher than 100MG/L in short time. Water can't involve the greasy dirt and mechanical quality impurity and take the measure of killing algae and others stabilize the water quality in case of necessity.
F. The temperature does not exceed 60, users can order if exceed that case. If users need the fire-retardant type cooling tower, please prove at the time of ordering, our factory can meet the demands.
G. Sprinkling water-pipe make holes according to the names flow, If the actual flow is differ by 15% with names flow, the user should propose while ordering.
H. The pressure of the enter-water pipe is 2-5 meters of water columns probably. Until the pressure can't be much higher in the design, water will float.
I. Electrical machinery, air blower are provided together, that need our factory to send person to install or technological guidance what should add additional fee .
J. If the user need absorbing water directly under cooling tower body, it need to install" automatic-feed pipe"," rapid-feed pipe "," blow down pipe"," overflow pipe" and especially propose while ordering.
