What is the efficiency of a cooling tower?

Range: The difference between the cooling tower inlet temperature (Hot Water Temperature) and cooling tower outlet temperature (Cold water temperature) is called Range of Cooling Tower. In practice, the cooling tower efficiency will be in between 65 to 70%.

How do you calculate tonnage of a cooling tower?

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.

How do you calculate kW cooling capacity?

Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per Kelvin. This gives us a final answer of Q = 2,500kW of cooling.

What is cooling tower capacity?

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 air flow in a cooling tower?

The formula is total heat removed (11.2) times pounds per minute of air (6.95) times 60 minutes per hour. 11.2 X 6.95 X 60 = 4, 670.4 BTU/Hr. Therefore, a tower with a 100 CFM motor at these conditions would be removing 4,670.4 BTU/Hr.

How many kW is in a ton?

1 ton ≈ 3.5169 kilowatts.

How many kW is a ton of AC?

3.517 kilowatts
3.517 kilowatts of power is equal to 1 ton of cooling capacity.

Which type of cooling tower is more efficient?

Counterflow (induced draft) systems are considered the most efficient of the two. Crossflow (forced draft) towers distribute hot water perpendicularly to the air flow, while counterflow towers distribute hot water directly into the air flow.

What is L G ratio in cooling tower?

The L/G ratio of a cooling tower is the ratio between the water and the air mass flow rates. Cooling towers have certain design values, but seasonal variations require adjustment and tuning of water and air flow rates to get the best cooling tower effectiveness.

How do you convert watts to tons on air conditioning?

Convert from Watts to Tons of refrigeration….Watts to Tons of refrigeration.
