The difference between cold ton and water ton of closed cooling tower

The difference between cold ton and water ton of closed cooling tower

  What is the difference between the cooling ton and the water ton of the closed cooling tower? What does the cooling ton and the water ton of the closed cooling tower mean?mMcCooling tower noise reduction treatment manufacturer

  Closed cooling towers use "cold ton" to identify the type of tower more than open cooling towers. It is particularly important to note that in the refrigeration system, the cooling ton defined for the refrigerator and the cooling tower are related, but they are not the same. The former is the cooling ton of cooling capacity, and the latter is the cooling ton of heat dissipation. Under the premise, they are called "cold tons".mMcCooling tower noise reduction treatment manufacturer

  1. Refrigerator cooling capacity cooling tonsmMcCooling tower noise reduction treatment manufacturer

  The refrigerating capacity of the refrigerator, also known as the freezing ton, has a metric definition and an imperial definition. The industry also usually calls it Japanese ton, American ton or British ton:mMcCooling tower noise reduction treatment manufacturer

  The metric system is defined as:mMcCooling tower noise reduction treatment manufacturer

  1 cold ton defined by the metric system is the cooling capacity necessary for 1 ton of plump water at 0°C to freeze to 0°C ice in 24 hours. According to the melting heat of ice being 333.59KJ/Kg, metric 1RT (cold ton) = 3320 kcal/h=3.861kw, also known as Japanese cold ton in the industry;mMcCooling tower noise reduction treatment manufacturer

  Imperial is defined as:mMcCooling tower noise reduction treatment manufacturer

  imperial definitionmMcCooling tower noise reduction treatment manufacturer

  1 cold ton is 2000 Lb (lbs)32. Frozen plump water to 32 in 24 hours. The necessary cooling capacity of F ice, according to the melting heat of ice 144Btu/LbmMcCooling tower noise reduction treatment manufacturer

  Gauge (Btu is British thermal unit, defined as the heat required for 1Lb of water temperature to drop 1.F, then 1Btu=252cal=1055.06J, andmMcCooling tower noise reduction treatment manufacturer

  1Lb=0.453592Kg, so 144Btu/Lb=334.95 KJ/Kg), so the imperial 1RT=3024 kcal/h=3.517kw,mMcCooling tower noise reduction treatment manufacturer

  Also called American cold ton; perhaps according to British cold ton: 1 British cold ton = 3373 kcal/h = 3.923 kw, 1 new British cold ton = 3590 kcal/h = 4.175 kw.mMcCooling tower noise reduction treatment manufacturer

  2. Cooling tower cooling tonmMcCooling tower noise reduction treatment manufacturer

  Regarding the cooling capacity of the closed cooling tower, we have to consider the heat released by the cooling tower in the cooling cycle, in addition to the cooling capacity, there is also the power consumption of the compressor, and there are also differences between the metric and imperial definitions.mMcCooling tower noise reduction treatment manufacturer

  The metric system is defined as:mMcCooling tower noise reduction treatment manufacturer

  1CRT——When the wet bulb temperature of the atmosphere is 27℃, 13LPM (liter/min, or 0.78m3/h) of puremMcCooling tower noise reduction treatment manufacturer

  The cooling of water from 37°C to 32°C is 1 ton, and its heat dissipation is 4.515Kw.mMcCooling tower noise reduction treatment manufacturer

  (29.4°C), which is 1 British ton of refrigeration, and its heat dissipation is 4.392 Kw; it can also be understood that when the wet bulb temperature of the atmosphere is 28°C, 13LPM (liter/min, that is,mMcCooling tower noise reduction treatment manufacturer

  0.68m3/h) of pure water is cooled from 37℃ to 32℃, which is 1 cold ton, and its heat dissipation is 4.392Kw.mMcCooling tower noise reduction treatment manufacturer

  3. my country's current cooling tower cooling ton indicatormMcCooling tower noise reduction treatment manufacturer

  In my country, there is currently no national standard for closed towers. For closed cold water towers, when the cold ton mark is used,mMcCooling tower noise reduction treatment manufacturer

  The normative planning conditions are usuallymMcCooling tower noise reduction treatment manufacturer

  37°C/32°C/27°C; when it is marked with water tons (that is, flow rate), the standard planned working conditions are usually 37°C/32°C/28°C or 43°C/33°C/28°C. Above atmospheric dry bulb temperature is 31.5℃, atmospheric pressuremMcCooling tower noise reduction treatment manufacturer

  9.94×104Pa. Using the cold ton mark and the water ton mark, the heat removal coefficients of the two are inconsistent when the working conditions are changed. For products with other design conditions, it must be converted to the standard design conditions, and in the sample or product specification, the cooling tons or the flow rate of the cooled water should be marked according to the standard design conditions.mMcCooling tower noise reduction treatment manufacturer
