Low noise cooling tower

FRP low noise cooling tower is based on the low noise cooling tower and take a series of noise control measures, the standard point noise value than the corresponding low noise type low ~ 5dB (A). Round countercurrent FRP cooling towers are suitable for places where noise requirements are more stringent, such as hotels, hospitals, public buildings, and neighborhoods.

Product Description Code Meaning:
D-low noise type, B-glass steel, N-flow, L-cooling tower 125T-water.


Design Parameters:

Air wet bulb temperature τ = 28 ℃, water temperature t1 = 37 ℃, water temperature t2 = 32 ℃.

Selection Use:
With the development of industrial production and the continuous improvement of people's living standards, control of water pollution, rational development and utilization of water resources is imminent. To this end, many units generally use FRP cooling towers as an ideal energy efficient equipment, the implementation of internal water closed circuit, improve the recycling rate, effectively reduce the cost of the cost, while people to adjust the surrounding environment temperature and humidity, cleanliness and The effect of noise is converted into reality.
Round counter-current FRP cooling tower using counter-current gas-heat exchange technology, packing with high-quality modified polychlorinated ethylene plate to spread the area of water; by rotating the water way to achieve uniform distribution of water and enhance the cooling effect. I plant has been on this series of products designed to make partial improvements to make it more reliable, durable, easy assembly.

(1) DBNL3 series of low-noise glass fiber reinforced plastic cooling tower - suitable for water temperature drop 3 to 8 degrees of air conditioning and refrigeration units and other general cooling occasions.
(2) CDBNL3 series of ultra-low noise glass steel cooling tower - for more demanding on the noise of hotels, hospitals, public buildings and neighborhoods closer to the occasion.
(3) GBNL3 series of high temperature industrial glass fiber reinforced plastic cooling tower - for water temperature drop 10 ~ 25 degrees industrial water circulation cooling system.
Model composition: round countercurrent FRP cooling tower has three major series: DBNL3, CDBNL3, GBNL3.


Performance and Options:

1, design parameters
1) standard conditions: water temperature t1 = 37 ℃, the water temperature t2 = 32 ℃, the design wet bulb temperature τ = 28 ℃, the water temperature Δt = 5 ℃, cold high t2-τ = 5 ℃
2) the temperature conditions: water temperature t1 = 43 ℃, the water temperature t2 = 33 ℃, the design wet bulb temperature τ = 28 ℃, the water temperature Δt = 10 ℃ cold high t2-τ = 6 ℃
3) high temperature conditions: water temperature t1 = 60 ℃, the water temperature t2 = 35 ℃, the design wet bulb temperature τ = 28 ℃, the water temperature Δt = 25 ℃ cold high t2-τ = 8 ℃
2, the choice of water when the water Q, water temperature t1, water temperature t2 and design wet bulb temperature τ, and then according to the thermal performance curve to determine the model. The thermodynamic performance curve is shown in Schedule 1, Schedule 2. On the curve table other than the working conditions, can be calculated thermally, the packing volume of the bulk coefficient β × ν as follows:
1.2 times the nominal flow: β × ν = 18600
1.0 times the nominal flow: β × ν = 17800
0.8 times the nominal flow: β × ν = 17000
3, the operation of the weight of the tower by holding the water half of the calculation, if by filling the water should be multiplied by 1.5.
4, the series cooling tower for the coldest month average temperature of not less than -10 ℃ in the region, the temperature should be low to prevent the user should be prepared to prevent the freezing of the requirements, in order to configure the drainage guide ring, do not make water flow to the louver. During the intermittent operation of the winter, you can add electric heat pipe in the tank. This series of cooling towers for the coldest monthly average temperature of not less than -10 ℃ in the region, the temperature should be low to prevent the user should be prepared to prevent the freezing of the requirements in order to configure the drainage guide ring, do not make water flow to the louvers. During the intermittent operation of the winter, you can add electric heat pipe in the tank.
5, the circulating water turbidity is not greater than 50 mg / l, short-term no more than 100 mg / l, should not contain oil, if necessary, to take algae and water quality and stability measures.
6, the water temperature does not exceed 60 ℃, such as more than can be specified in the order, the factory from the selection to be resolved. For flame retardant cooling tower, please specify when ordering, the factory can meet the requirements.
7, the distribution of water pipes in nominal flow openings, such as the actual flow and nominal flow difference of ± 15% or more, the user should be stated when ordering.
8, the water pressure is about 2 to 5 meters water column, the design should not be too high pressure, otherwise it will produce water drift phenomenon.
Ultra-low noise cooling tower is based on the low noise cooling tower and adopted a series of noise control measures, the standard point noise value than the corresponding low noise type low ~ 5dB (A). Round counter-current FRP cooling towers are suitable for places where noise requirements are more stringent, such as hotels, hospitals, public buildings and neighborhoods. Its base piping and motor power are the same as the corresponding low noise cooling towers , Cooling water and air volume and low noise cooling tower the same.
