What is chiller efficiency kW ton?

What is chiller efficiency kW ton?

Whereas a typical packaged cooling unit has an efficiency of 1.1 to 1.4 kW/ton, a chiller-based system can have a full load efficiency that is far lower—values of 0.8 to 1.0 kW/ton for the entire chiller plant are typical.

How do you calculate tonnage of a cooling tower?

To calculate the cooling tower capacity in tons, multiply the water flow rate by the temperature differential, then divide by 12,000, then multiply by 500.

How much energy do cooling towers use?

Based on seasonal operation of approximately 2,000 hours with a VFD controlled fan, the tower fan motor would consume 11, 297.7 kWh and the system pump energy consumption would be approximately 3,416 kWh.

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.

How do you calculate cooling efficiency?

Cooling Tower Efficiency Calculations

  1. Approach = Cold Water Temperature – Wet Bulb Temperature.
  2. Cooling Tower Efficiency =
  3. (Hot Water Temperature – Cold water Temperature) x 100/
  4. (Hot Water Temperature – Wet bulb temperature)

How many kW does a chiller use?

High-efficiency chillers can produce chilled water using less than 0.50 kW per ton of cooling capac- ity.

What is the efficiency of cooling tower?

In practice, the cooling tower efficiency will be in between 65 to 70%. In summer season the ambient air wet bulb temperature raises when compared to winter season so cooling tower efficiency limiting in summer season.

What is cooling kW?

The cooling capacity is defined as the amount of cooling (usually expressed in terms of kW or tons of cooling) delivered by the system divided by the amount of air passing through the system (in kg/s or cfm).

How can we increase the efficiency of cooling tower?

How to Increase Your Industrial Cooling Tower Efficiency

  1. Save energy.
  2. Reduce the amount of water being consumed.
  3. Decrease the amount of chemicals required for water treatment.
  4. Extend the equipment service life.
  5. Reduce operating costs, overall.

How many kW is a 4 ton AC?

What size generator to run 1-5 ton ac unit?

Central AC Unit Size (Ton) Generator Size (kW)
3 ton 14 kW
3.5 ton 16 kW
4 ton 17 kW
5 ton 20 kW

What is the relation between COP and kW ton of refrigeration?

1 kW/ton = 3.516/COP .

How do you calculate the efficiency of a cooling tower?

Cooling Tower Thermal Efficiency Calculations

  1. Approach = Cold Water Temperature – Wet Bulb Temperature.
  2. Range = Hot Water Temperature – Cold Water Temperature.
  3. Cooling Tower Thermal Efficiency = Range/ (Range + Approach) x 100.
  4. COC = Silica in Cooling Water / Silica in Makeup Water.

How many kW is a ton of AC?

3.517 kW
Popular Answers (1) cooling capacity of 1 ton is equal to 3.517 kW of power. =1.5*3.517/2.7=1.954 kW. AC consists of two units, Indoor unit which is called the evaporator and the Outdoor Unit which called the Compressor.

Can you calculate kW from kWh?

How to convert kilowatts-hour to kilowatts. How to convert energy in kilowatt-hour (kWh) to electric power in kilowatts (kW). You can calculate kilowatt from kilowatt-hour and hours, but you can’t convert kilowatt-hour to kilowatt, since kilowatt-hour and kilowatt units represent different quantities.
