As electricity prices and building’s power consumption continue to rise, energy costs are getting increased scrutiny. Cooling accounts for more than 40 percent of electricity usage within a well designed building and, in many cases, represents a significant opportunity to reduce building’s energy costs.
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 cool these buildings;
The choice of system can have a dramatic effect on the energy consumed by the building due to their different electrical demands.
Ventilation systems can provide comfort cooling for most of the year. During prolonged periods of high temperatures they are unable to maintain internal temperatures at comfortable levels. Air Conditioning is effective but can be expensive to operate. Evaporative cooling, which can produce comfortable
temperature consistently provides an intermediate solution which consumes only a fraction of the electricity.
Evaporative cooling utilizes the basics of air and water to produce a very significant temperature drop. Evaporative cooling can also create a desired amount of humidification to increase efficiency of machinery or comfort in buildings. Because of its effectiveness in cooling and humidification,
evaporative cooling is the primary choice in such industries as: gas turbine, greenhouse, livestock farming, automobile painting, residential cooling, and commercial building climate control.
An evaporative cooling system consists of pads which are designed to absorb and hold water and give maximum surface area for air and water contact. As air passes through the pads the natural evaporation of water creates cooled and humidified air.
The economy of using evaporative cooling is surprising to most people. A 90% reduction in energy used by using evaporative cooling compared to a conventional air conditioning unit seems too good to be true.
Energy costs are likely to continue to rise in the future as will the energy requirements of most organizations. Taking steps today to increase the efficiency of the cooling system can offset the impact of rising energy costs.
DRI’s Arctic Coolers, offer a completely natural way of producing refreshing cool air. Our Arctic range Evaporative cooling units have been specifically designed for the cooling of industrial and commercial buildings. They are capable of lowering the fresh air temperature by 7-12 degrees, e.g- the air-off temperature from the evaporative cooler for an outside temperature of 40-43 degrees C can be as low as 28-30 degrees C. They allow cool fresh air to circulate throughout a building forcing the stale hot air to be displaced out.
Unlike air- conditioning which operates with re-circulated air, Arctic coolers operate on the principle of air change and work as part of balanced ventilation system.
DRI Arctic Coolers use the EcoCool Evaporative Cooling Pads. EcoCool pads are highly efficient, consistent in performance over a very long life, self-supporting, highly absorbent and can be easily cleaned. They allow higher cooling with lower air volume and are over 80% efficient.
