EcoCooling installs evaporative coolers at Hospital

EcoCooling evaporative cooling is an alternative to refrigeration based air conditioning and is used as part of a balanced ventilation system to cool buildings. A typical EcoCooler, rated at 30KW, can reduce electricity costs by over £2000 and save 10,000kg of carbon over a year compared to an equivalent refrigeration based system. EcoCooling is suitable for schools, hospitals, sports centres and other public buildings.

Ventilation systems can be very effective at maintaining comfortable conditions in buildings because of low ambient temperatures found for much of the year. However during hot periods when the outside air temperatures rise above 25C these conditions cannot be maintained. In the UK, when the weather is hot, the relative humidity is low, and evaporative cooling can provide cool air. When this hot dry air is passed over the wet filter pads found in an evaporative cooler the air is cooled. The air off temperature will never normally exceed 23C - even on record breaking 35C days. It is this combination of fresh air ventilation, coupled with evaporative cooling, which can meet the needs for comfort cooling of many buildings: public, commercial and industrial.

A typical hospital installation was recently completed at Burton upon Trent Health Trust. The out patients waiting areas, situated on the top floor, was built with no provision for either cooling or ventilation and consequently this led to very uncomfortable conditions. Two side discharge EcoCoolers, with sound attenuation, were installed as part of a balanced ventilation system.

As with all water based systems in hospitals a stringent Legionnaires' disease risk assessment was performed. The combination of hygienic engineering, sophisticated process controls and comprehensive alarm functions provided sufficient assurance for what is probably the most rigorous standards in Europe.

EcoCooling is a simple, safe and low cost alternative to traditional refrigeration based systems suitable for comfort cooling of whole buildings or spot cooling of people and machines. There are no harmful refrigerants and no re-cycling of air; doors and windows can remain open allowing people to breath in clean fresh air. The considerable cost savings and contribution to carbon savings make EcoCooling the logical way to provide comfortable conditions in many buildings.
