Cooling tower water consumption per ton of refrigeration Hi all, How much water is expected to be consumed by a cooling tower per ton of refrigeration? From the wikipedia article: At first I misread the article as saying 15,000 Btu/hour would evaporate 3 gallons per minute. It is actually saying that 15,000 Btu/hour equals delta T of 10F at 3 gallons per minute.
Evaporative Condensers - Cooling Towers, Evaporative ... The heat removed in the condenser is dependent upon the temperature rise and the flow rate of the water. For an average heat rejection of 15,000 BTUH/TR of refrigeration and a water temperature rise of 20°F in the condenser, approximately 1.5 GPM of water per ton must be supplied to and wasted from the refrigerant condenser.
Cooling Tower Efficiency - Engineering ToolBox The water consumption - or the amount of make up water - of a cooling tower is about 0.2-0.3 liter per minute and ton of refrigeration. Compared with the use and waste of city water the water consumption can be reduced with about 90 - 95% .
COOLING TOWERS - me.ua.edu cooling tower ton is defined as cooling 3 gpm of water from 95°F to 85°F at a 78°F entering air wet-bulb temperature. At these condi- tions, the cooling tower rejects 15,000 Btuih per nominal cooling tower ton. The historical derivation of this 15,000 Btulh cooling tower ton, as compared to the 12,000 Btuih evaporator ton, is based

Chiller Cooling Capacity - How to calculate - The Engineering ... The water flow rate of chilled water into the evaporator is 0.0995m3/s, the inlet temperature is 12*c and the outlet temperature is 6*c. This means the average temperature is 9*c so we lookup the water properties at this temperature to find the density of 999.78kg/m3 and a specific heat capacity of 4.19kJ/kg/K.

Cooling Tower Makeup Water - CheCalc Drift is entrained water in the tower discharge vapors. Drift loss varies between 0.1 and 0.2 % of Circulation flow. It can be as low as 0.01 % of circulation flow, if the cooling tower has windage drift eliminators.
Water Calculator : My Cooling Tower Water Calculator. This cooling tower water efficiency calculator has been developed by AIRAH with support from a wide range of industry stakeholders, water corporations and the Victorian Government. NB: This calculator is for towers located in VICTORIA and the database only works with micro Siemens conductivity readings.
Cooling Towers: Evaporation Loss and Makeup Water | Page 1 The approach is defined as the difference between the water temperature at the tower outlet ( t out) and the wet-bulb temperature of the inlet air ( T w,in). The approach represents the cooling tower capability. In general, the larger the tower, the smaller is the approach. In this case study, the approach is 4°C.
Cooling Tower Evaporation Rule of Thumb - Veolia Water When dealing with a cooling tower, to cool the incoming water being sprayed over the tower by 10 qF, then 1% of the flowrate over the tower must be evaporated. This is where the rule of thumb For every ' T of 10 °F, 1% of the recirculation rate must be evaporated to achieve this cooling comes from.
What Is A Ton of Refrigeration? – Power Knot Thus, 1 tonne of refrigeration is 10% larger than 1 ton of refrigeration. Another unit of measure is the calorie which is the amount of heat removal required to raise or lower the temperature of one gram of water by one °C. A kilo-calorie is the amount of heat required to raise or lower 1 kg of water by 1°C. One ton of refrigeration is equal ...
5 Sizing Steps for Chillers in Plastic Process Cooling ... No matter what your application, there is a single formula for determining the size of chiller you need. Before you begin, you must know three variables: The incoming water temperature The chilled water temperature required The flow rate For our example, we will calculate what size chiller is required to cool 40 GPM (gallons per minute) from 70 °F to 58 °F?

HVAC FORMULA: COOLING TOWERS The temperature difference between inlet and outlet water (EWT - LWT) is normally in the range 10 – 150 C. The water consumption - the make up water - of a cooling tower is about 0.2-0.3 liter perminute per ton of refrigeration. Cooling towers use the principle of evaporative cooling in order to cool water.

Water Conservation » SPX Cooling Technologies » Green Cooling tower systems are somewhat like humidifiers or small room vaporizers. If the system is operated for a long time, the water gets more and more concentrated with the minerals remaining when water is evaporated. These small systems are usually periodically dumped and replaced with fresh water to prevent the build-up of scale.
