The main purpose:

(1) Low-noise series glass fiber reinforced plastic cooling tower-suitable for general cooling occasions such as air-conditioning refrigeration units with a water temperature drop of 3-8 degrees.

(2) Ultra-low noise series glass fiber reinforced plastic cooling towers-suitable for hotels, hospitals, public buildings with stricter noise requirements and occasions closer to residential areas.

(3) Medium and high temperature industrial series glass fiber reinforced plastic cooling tower Applicable to industrial water circulating cooling system with water temperature drop of 10-25 degrees.

1. Design parameters

1) Standard working conditions: inlet water temperature t1 = 37 ℃, outlet water temperature t2 = 32 ℃, design wet bulb temperature τ = 28 ℃, namely water temperature Δt = 5 ℃, high cooling amplitude t2-τ = 5 ℃

2) Moderate temperature working conditions: inlet water temperature t1 = 43 ℃, outlet water temperature t2 = 33 ℃, design wet bulb temperature τ = 28 ℃, namely water temperature Δt = 10 ℃, cold amplitude high t2-τ = 6 ℃

3) High temperature working conditions: inlet water temperature t1 = 60 ℃, outlet water temperature t2 = 35 ℃, design wet bulb temperature τ = 28 ℃, namely water temperature Δt = 25 ℃, cold amplitude high t2-τ = 8 ℃

2. Instructions when selecting

Water quantity Q, inlet water temperature t1, outlet water temperature t2 and design wet bulb temperature τ, and then determine the model according to the thermal performance curve. See Appendix 1 and Appendix 2 for thermal performance curves. For the working conditions other than the curve table, thermal calculation can be performed. The volumetric bulk coefficient β × ν of the filler is as follows: at 1.2 times the nominal flow rate: β × ν = 18600 at 1.0 times the nominal flow rate: β × ν = 17800 0.8 times the nominal Flow rate: β × ν = 17000.

3. The running weight is calculated by pressing the half-deep water of the tower body. If it is calculated by full water, it should be multiplied by 1.5.

4. This series of cooling towers are used in areas where the average temperature in the coldest month is not lower than -10 ℃. Users at low temperatures should put forward the requirements of preventing freezing, so as to configure a water diversion ring to prevent water from flowing onto the louvers. During the intermittent operation in winter, electric heating pipes can be added to the water tank.

5. The turbidity of the circulating water is not more than 50 mg / L, and not more than 100 mg / L in a short period of time. It is not suitable to contain oil pollution. If necessary, take measures to eliminate algae and stabilize water quality.

6. The applicable water temperature does not exceed 60 ° C. If it exceeds the limit, it can be stated when ordering, and the factory will solve it from the selection of materials. If you need a flame-retardant cooling tower, please specify when ordering, our factory can meet the requirements.

7. The water distribution pipe is opened according to the nominal flow. If the actual flow differs from the nominal flow by more than ± 15%, the user should explain when ordering

8. The water pressure of the inlet pipe is about 2-5 meters of water column. Don't design too high pressure, otherwise it will cause floating phenomenon.
