As the global temperature rises, the use of central air-conditioning is more and more widespread. In central air-conditioning, there are many cooling methods. Cooling with air is called air cooling; cooling with water is called water cooling. However, in large-scale central air conditioning systems, water is mostly used as the heat transfer and cooling medium, that is, closed cooling towers are used. This is because water has good chemical stability and is not easy to decompose; its heat capacity is large, and it is within the usual temperature range. It will not produce significant expansion or compression; its boiling point is high, and it will not vaporize in the condenser under general operating conditions; at the same time, the water has a wide range of sources, good fluidity, and easy to transport and distribute, relatively speaking , The price is also lower.
Then I believe we all care about how the central air-conditioning and closed cooling tower should be deployed. The following will give us a detailed explanation of the central air-conditioning closed cooling tower selection plan.
1. The water temperature connection between the central air conditioner and the closed cooling tower
For the selection of central air-conditioning closed-type cooling towers, the inlet and outlet water temperatures must be determined first. This is related to the problem of the degree of cooperation between the central air-conditioning and closed-type cooling towers. Type cooling tower, those will cause damage to the internal components of the closed type cooling tower. The closed cooling towers on the market are classified by temperature: low temperature type, standard type, medium temperature type, and high temperature type. The difference between various types of closed cooling towers lies in the temperature resistance of the filler and the cooling speed of the closed cooling tower.
The outlet water temperature of the central air conditioner = the inlet water temperature of the closed cooling tower, and the inlet water temperature of the central air conditioner = the outlet water temperature of the closed cooling tower.
2. Size selection of closed cooling tower
I believe we will encounter a problem in the selection of central air-conditioning closed cooling towers, that is, how many tons of towers should I choose? Or what size tower to choose? In fact, the number of tons of towers depends entirely on the circulating water volume of the central air-conditioning system. The number of water-ton closed cooling towers for the central air-conditioning unit, and the number of cooling-ton closed cooling towers can be selected for the central air-conditioning unit. What? What is a ton of water? What is cold tons?
Water ton definition: the circulating water volume of the cooling water tower per hour, the circulating water volume of 7.2 tons per hour is equipped with a 10 ton cooling tower; the cooling ton definition: the cooling capacity of the cooling water tower per hour, and the cooling ton is the circulating water volume of the cooling water tower of 100 tons It is 72 tons of water per hour.
3. Selection of raw materials for closed cooling towers
The closed cooling tower is divided into: stainless steel closed cooling tower, metal heat resistance closed cooling tower, glass fiber reinforced plastic closed cooling tower, and hybrid closed cooling tower. The raw material of the closed cooling tower depends on the water quality of the process fluid, and the closed cooling tower can use stainless steel closed cooling tower in the application of central air conditioning.
4. The floor space and operating weight of the closed cooling tower
In fact, the floor space and operating weight of a closed cooling tower are only details in the selection of a closed cooling tower. Many people think it is not important, but this is very reliable. Why is it reliable? When you buy a closed cooling tower, you find that your company can't put it down or put it on the top of the building can't bear the weight of the closed cooling tower at the time of installation. If this kind of thing is discovered, would it be unreliable? Closed cooling towers under 100 tons cover an area of about 6 square meters with an operating weight of about 4000 kg; closed cooling towers with 100 to 500 tons cover an area of about 15 square meters and an operating weight of about 10,000 kg. For the specific operating weight and floor space of each tonnage, we can contact the cooling tower manufacturer China trlon air conditioner for detailed parameters.
