As carbon emissions continue to rise, so does the outside ambient temperature, resulting in more and more businesses turning to Evaporative Cooling to cool and ventilate their business premises, to protect the quality of stock and production, and to maintain a comfortable and healthier working environment for staff and visitors.
By introducing Evaporative Cooling as an integral part of a balanced Ventilation system means that the temperature of a building can be controlled even on the hottest of days.
Evaporative Cooling or Adiabatic Cooling as its often referred to is the most natural, cost effective and environmentally friendly way to cool a building and processes and does so by introducing 100% fresh air to keep the temperatures down.
Designed to deliver the perfect ventilation and cooling solution for large industrial and commercial spaces such as factories, warehouses, IT data centres, food manufacturing, pharmaceutical, leisure facilities, sporting arenas, hospitals, large retail outlets and many more.
Unlike the more traditional refrigerant air conditioning systems that use re-circulated air, evaporative cooling systems circulate 100% cool fresh air through a building and uses extraction to remove hot stale and unhygienic air and harmful refrigerants and pollutants.
Evaporative Cooling is an extremely popular and cost effective alternative to the more traditional refrigeration air conditioning systems. Offering potential savings of up to 90% in running costs and uses only 10% of the energy.
By building on this natural occurrence by installing air coolers into ventilation systems to naturally cool the air. Fans draw a constant flow of fresh outside air over saturated cooler pads to produce the evaporative cooling effect.
As the water evaporates, energy is lost from the air causing a reduction in the outgoing temperature, many describe this as the same feeling that you get whilst at the seaside when a sea breeze passes over the ocean.
The fresh, cool air is then introduced into the building to cool it and the hot exhaust air is removed through open doors and windows and with the introduction of extraction fans to keep the building cool.
By using evaporative cooling as an integral part of a ventilation system means that the temperature of a building can be controlled even on the very hottest of days. In fact, the hotter the outside temperature and the lower the humidity, the greater the cooling effect
Please see the table below for the cooled temperature achievable at different ambient temperatures and humidities.
Relative Humidity | Relative Humidity | Relative Humidity | Relative Humidity | |
Temperature | 20% | 40% | 60% | 80% |
20°C | 10.2 | 13.1 | 15.6 | 17.9 |
25°C | 13.7 | 17.0 | 20.0 | 22.6 |
30°C | 17.0 | 21.0 | 24.4 | n/a |
35°C | 20.4 | 25.1 | n/a | n/a |
Typically uses less than 10% of the electricity than conventional air conditioning | Higher electrical demand due to the refrigerant circuit compressor |
No refrigerants | Use of environmentally damaging refrigerants |
Supplies 100% fresh cooled air | Uses mainly recycled air |
Can accommodate the very hottest of days | Performance reduces at high ambient temperatures |
Low carbon dioxide footprint | Higher carbon dioxide impact |
As part of managing health and safety within your business its important that you control risks within your work place to include when suppliers and contractors are asked to work on site.
By choosing OKEL as your preferred contractor you will have reassurance in knowing that we understand the importance of assessing workplace risks and will work closely with you in the time leading up to the installation to ensure the right safety measures have been put in place to reduce the risks of work place dangers to both employees and visitors to site.
