Oasis ice peak cooling tower how to choose the model

First of all, let's look at what options are available. Of course, the cooling tower is not good or bad, just look at whether it is suitable or not.

Cooling tower is divided into ventilation mode：

① Natural draft cooling tower; ② Mechanical draft cooling tower; ③ Mixed draft cooling tower

According to the contact mode of water and air, the cooling tower is divided:

① wet cooling tower; ② dry cooling tower; ③ dry and wet cooling tower.

Cooling tower according to the flow direction of hot water and air:

① counterflow cooling tower; ② crossflow cooling tower; ③ compound flow cooling tower

According to the application field, the cooling tower is divided:

① industrial cooling tower; ② air conditioning cooling tower.

Cooling tower according to the noise level:

① ordinary type cooling tower; ② low noise type cooling tower; ③ ultra low noise type cooling tower; ④ ultra quiet type cooling tower.

First understand how the cooling tower selection:

First of all, to determine the cooling tower water temperature, so as to choose the standard type cooling tower, medium temperature type cooling tower or high temperature type cooling tower.

2, determine the use of equipment or can be in accordance with the site conditions of the noise requirements, you can choose cross-flow cooling tower or counterflow cooling tower.

3, according to the cooling capacity of the chiller or refrigerator to choose the cooling capacity of the cooling tower, generally speaking, the cooling capacity flow is greater than the cooling capacity of the cooling equipment. (Generally take 1.2-1.25 times).

4, multiple parallel as far as possible to choose the same type of cooling tower.

      

Next, let's take a look at the cooling tower selection instructions:

1, please indicate the specific type of cooling tower, or the flow rate per hour.

2, cooling tower into the tower temperature and out of the tower water temperature.

3. Please explain what equipment to cool down, whether there is a circulating pool on site, and what are the installation conditions on site.

4. If spare parts and other accessories are needed, please indicate whether there are other requirements.

Please explain the use environment and specific conditions in order to select the appropriate cooling tower model.

6. Please indicate the special circumstances and models when ordering, and the design shall be specially designed according to the contract and technical agreement of both parties.

Finally, the cooling tower selection should pay attention:

1. The structural material of the tower body of the cooling tower should be stable, durable, corrosion-resistant, and the assembly and coordination should be accurate.

2. Uniform water distribution, less wall flow, reasonable selection of splashing device, not easy to block.

3. The type of cooling tower drenching filler meets the requirements of water quality and water temperature.

4. Fan matching can ensure long-term normal operation, no vibration and abnormal noise, and the blades have good water erosion resistance and sufficient strength. The installation angle of the fan blade is adjustable, but the angle must be consistent, and the current of the motor does not exceed the rated current of the motor.

5, low power consumption, low cost, small and medium-sized steel frame glass cooling tower also requires light quality.

6. The cooling tower should be avoided as far as possible in the heat source, exhaust gas and flue gas occurrence point, chemical stacking place and near the coal pile.

The distance between the cooling towers or between the tower and other buildings, in addition to considering the ventilation requirements of the tower, the tower and the building interaction, should also consider the building fire, explosion-proof safety distance and the cooling tower construction and maintenance requirements.

The direction of the inlet pipe of the cooling tower can be rotated by 90 °, 180 ° and 270 °.

The material of the cooling tower can withstand the low temperature of -50 ℃, but it should be explained when ordering for areas where the monthly average temperature is lower than -10 ℃, so as to take anti-icing measures. The cost of the cooling tower increased by about 3%.

10, the turbidity of circulating water is not more than 50mg/l, short-term not more than 100mg/l should not contain oil and mechanical impurities, if necessary, algae and water quality stability measures should be taken.

11. The water distribution system is designed according to the nominal water quantity. If the difference between the actual water quantity and the nominal water quantity is more than 15%, it should be explained when ordering so as to modify the design.

12, cooling tower parts in the process of storage and transportation, it is not allowed to press heavy objects, not exposure, and pay attention to fire prevention. During the installation, transportation and maintenance of the cooling tower, open flames such as electricity and gas welding shall not be used, and firecrackers and fireworks shall not be set off nearby.

13, round tower multi-tower design, the net distance between the tower and the tower should be kept not less than 0.5 times the diameter of the tower. Cross-flow column and counter-flow column can be arranged in parallel.

14, the selection of water pump should be matched with the cooling tower to ensure the flow, lift and other process requirements.

When choosing multiple cooling towers, choose the same model as much as possible.
