Watkins Hire are a Leading temperature control rental company, after 149 years Watkins Hire continue to innovate, the latest innovation from Watkins Hire is their new mobile evaporative air cooler for Low carbon temporary cooling.
Each KwikCOOL Mobile Evaporative Cooler provides Low carbon cooling for 110m2(1184ft2) with a power consumption of just 3 amps
“Evaporative cooling provides a cost effective solution for cooling large areas and at the same time is ecologically attractive as it uses very little energy and emits no greenhouse gases or carbon products” says Roderick Williams, Sales Director of Watkins Hire.
THE GREENER WAY TO COOL
The amazing thing about evaporative cooling, and the key to its environmental credentials, is that it uses water as its working fluid, and not potentially harmful ozone depleting CFC refrigerants. A constant flow of fresh air is simply drawn over water saturated pads, which act as both ‘chiller’ (as the water evaporates off the pads it removes the heat) and ‘filter’ of dust and pollen. The result is a cooling system which has incredibly low running costs – evaporative cooling uses 85% less energy than traditional air conditioning – and a tiny carbon footprint.
Many modern buildings require cooling either for the comfort of the occupants or to protect the processes or equipment they contain. There are three typical methods which can be employed to provide temporary space cooling these buildings; ventilation air handlers, evaporative cooling or a refrigeration based air conditioning system. The choice of system can have a dramatic effect on the total carbon emissions of the building due to their different electrical demands. See our Air Conditioning comparison table below to compare the features of Air Conditioning with Evaporative Cooling.
Ventilation Air handler systems can provide comfort cooling for most of the year. During prolonged periods of high temperatures they are unable to maintain internal temperatures below 25°C. Refrigeration based systems are effective but can be expensive to operate. Mobile Evaporative coolers, which can produce air consistently below 22°C in the UK climate, provides a temporary cooling solution which consumes only a fraction of the electricity.
For Low carbon cooling Mobile evaporative coolers typically consumes less than 15% of the electricity compared to the equivalent rated refrigeration based cooling system.
The latest building regulations have resulted in buildings which require less heating. The unintended consequence of this, in many instances the activities, heat generating equipment and number of occupants within the building now generate more heat than is required to maintain a comfortable temperature.
During the winter of 2008 Watkins Hire experienced many customers with buildings which required temporary air conditioning systems to operate during the winter! Electricity usage and the associated carbon effect is increased dramatically. An evaporative cooling can address this with a cost effective and low carbon solution.
Low Carbon Cooling Example
The example shows how this electricity saving can result in 1.5 tonnes of carbon savings for a 30KW cooling requirement.
A building requiring 30KW peak load and 20KW minimum load. Cooling employed from April to October from 6am to 6pm 5 days per week in London with electricity cost 8p/kWhr and water cost £1.20/m3
