Evaporative Cooling Performance

 

Savings of between 10 and 15% are possible when Evaporative Water Cooling is employed instead of traditional air cooling methods.

The performance of an EcoCooler is dependent upon the temperature of the air and its relative humidity. Higher temperatures give greater cooling. Low relative humidity gives greater cooling

In the UK during a typical hot period the ambient temperature approaches 30°C. This coincides with a Relative Humidity of under 50%. As the air passes over the pads it will typically cool down to about 22°C. There is less cooling in the night as the temperatures reduce and the humidity rises.

Evaporative Cooling Applications: Food and Drink
Food and drink manufacturing routinely creates a hot environment which can be detrimental to comfort, product quality and equipment performance and reliability. One way to reverse this is with the installation of Evaporative Water Cooling.

Evaporative Cooling Applications: Modern Offices
Many modern offices are uncomfortable due to high occupancy, more equipment (computers etc) and improved building insulation. Evaporative Water Cooling can help improve working comfort and increase productivity.

Evaporative Cooling Applications: Schools
Many educational facilities have problems with high temperatures causing student and staff discomfort. A typical example of this is IT rooms. A refrigeration based air conditioning system is costly to install and run. It also has a significant carbon impact.

Evaporative Cooling Applications: Warehouse Cooling
Warehouses usually generate a high amount of hot air and without proper cooling and ventilation, become unpleasant environments to work in. Here is how Evaporative Water Cooling can help reduce heat and provide a cooled and more pleasant work atmosphere.

Evaporative Cooling Applications: Data Centres
EcoCooling can now offer evaporative cooling systems for data centres, UPS rooms, IT rooms and server rooms. Conventional Computer Room Air Conditioners (CRAC’s) are high users of electricity. An EcoCooling evaporative cooling system can significantly decrease these costs by over 90% giving potential pay backs of under a year and creating massive carbon savings.
