How is Basin cooling tower capacity calculated?
Multiply 500 times the water flow rate, times the temperature difference, divided by 12,000 or 500 x q x dt/12,000. The result is the tons of capacity of the cooling tower.
What is capacity of cooling tower?
The cooling tower’s capacity is the product of the mass flow rate of water, specific heat, and temperature difference. This can also be expressed as heat rejected in kCal/hr (Btu/h). Evaporation loss. This is the amount of water that is evaporated during the cooling process.
How do you calculate water for a cooling tower?
Cooling tower calculation
- Cooling tower makeup calculation. Water Make Up = D + E +B.
- Evaporation Loss = 0.00085 * 1.8 * C * Δt. C = Circulating water in.
- Blowdown : B = E = Evaporation Loss in.
- COC = Cycle of Concentration.
- Capacity of cooling Tower.
How much water does a cooling tower consume?
Traditional cooling towers can consume 2.4 gallons of water per minute of operation per 100 tons of cooling through evaporation (Vickers 2001). As cooling tower water evaporates, it leaves behind a concentration of dissolved solids including mineral deposits and other added process chemicals.
How do you calculate cooling capacity?
Calculating a Home’s Cooling Load
- Determine the dimensions of the room or home that needs cooling. For a room, you can do this with a measuring tape.
- For a room, multiply its length by its width to get the square footage.
- Multiply the square footage by 20. This is the measure of the BTU cooling load of the space.
What is meant by COC in cooling tower?
What is COC meaning? COC or the Cycles Of Concentration is an abbreviation, used when talking about cooling water or cooling tower water. The COC specifies, how often a fresh water added into the loop, can be used or pumped around, before the water has to blown down or bleed off from the cooling tower.
How is cooling capacity measured?
Every 12,000 BTUs that an air conditioner absorbs and removes from your home’s air in one hour equals one ton of cooling. If your A/C can do 48,000 BTUs per hour, that means a four-ton capacity.
What is COC water?
COC or the Cycles Of Concentration is an abbreviation, used when talking about cooling water or cooling tower water. The COC specifies, how often a fresh water added into the loop, can be used or pumped around, before the water has to blown down or bleed off from the cooling tower.
How do you calculate the volume of a cooling tower?
1. Estimate the system volume by measuring the sump of the tower and the water level in it. Multiply the number of cubic feet of water by 7.5 to get the number of gallons. Then add 10-20% additional water for piping, etc.
Why do cooling towers use so much water?
Cooling towers use lots of water. Given that their purpose is to dissipate heat from recirculating water used to cool air conditioners, that fact is hardly a surprise.
Which type of water is used in cooling tower?
tower make-up water Water
Water is widely used as a medium for cooling, due to its good heat transfer capacity.
How do you calculate kW and RT?
Electric motor driven chillers are rated in kilowatts per ton cooling.
- kW/ton = 12 / EER.
- kW/ton = 12 / (COP x 3.412)
- COP = EER / 3.412.
- COP = 12 / (kW/ton) / 3.412.
- EER = 12 / (kW/ton)
- EER = COP x 3.412.
What is the TP for cooling tower basin?
– TP10-26: Cooling Tower Basin Leakage Assessment & Mitigation – TP02-05: Concrete Basics, Materials, Selection in Design and Repair – TP71-07: Design of Concrete Basins for Cooling Towers
What is the holding capacity of a cooling tower?
Holding Capacity or System Volume : The holding capacity of a system is the amount of water in the system expressed in gallons (cubic meters). Normally most of the capacity of a system is contained in the cooling tower basin; the exact amount, however, can be determined only by conducting a TRASAR diagnosis or an ion concentration study.
How many tons is a 350 ton cooling tower?
The cooling tower selection is = 418 Nominal Tons x.83 DCF = 347 Rated cooling tower tons, or a 350-ton cooling tower selection. Alternate #1: A cooling tower can also be selected for this heat load based on a 25° Range of cooling.
What design data is required for cooling tower sizing?
The following design data is required for cooling tower sizing to properly select the appropriate model: The Design Heat Load is determined by the Flow Rate, and the Range of cooling, and is calculated using the following formula:
