Evaporative cooling system for your business

The benefits of evaporative cooling systems are plenty. There’s never been a better time to invest in an evaporative air conditioner, which is simple to maintain and operate and offers superior product performance. With energy prices escalating and heat waves hitting on Summer, evaporative air conditioning offers a significant and increasing edge on traditional air conditioning, when it comes to energy efficiency, healthier air flow, performance.

Evaporative cooling is becoming the most efficient option when cooling large areas, especially industrial and commercial spaces. Air conditioning is often not an option, because the capital and running costs would be prohibitive.

Cooling with water!

They do not use any sort of chemical refrigerants to cool the air: R718 is the only refrigerant used in evaporative cooling systems, that is WATER!

Evaporative air cooling uses between up to 87% less energy than conventional A/C and brings in 100% fresh outside air. That all adds up to very responsible environmental and energy saving characteristics.

However, there are common misconceptions about evaporative cooling. Sometimes building managers prefer not to opt for this technology just because it is too good to be true. Let’s explore the main objections and try to understand a little bit more.

Common misconceptions about Evaporative Coolers:
humid climates like coastal areas

Evaporative cooling systems are based on water evaporation. This means that cooling performance is impacted by outdoor relative humidity.

Generally speaking, the drier is the outdoor air, the better is the evaporative coolers’ performance. However, since Seeley International evaporative cooling units are very efficient, they can guarantee comfort cooling even in humid climates. In fact there are plenlty of evaporative coolers installations in Middle East Coastal areas, one for all Dubai, which is normally considered very humid. All those units are performing extremely well and business owners are very keen to replicate their investment in other premises.

Same happens with Doha or Muscat: we would think that evaporative cooling cannot work with such climate conditions. The truth is that many facilities managers and business owners have decided to install evaporative cooling in industrial plants, warehouses, workshops etc… It is all about choosing the right model, the right application and the proper extract system.

Temperature and humidity

It is also important to consider that humidity depends on the temperature. Specifically, during the portion of the day when temperatures are higher, relative humidity is lower. It is during these hot times that cooling is much more needed and it corresponds to the period when evaporative coolers work at their best (when relative humidity is lower). This time also correspond to working hours: this is why many companies decide to adopt evaporative cooling systems.

Evaporative coolers do not mist

Another very stubborn misconception is that evaporative coolers create airborne mist: nothing could be further from the truth. We should not confuse evaporative coolers with misting systems, as they involve a different technology.

Evaporative cooling system working principle is based on water evaporation and energy exchange. For this reason Direct Evaporative Coolers marginally increase humidity. But we need to think that temperature has dropped significantly and that human comfort is a combination between humidity and temperature.

Moreover, we need to remember that we are not only drawing air inside the building, but we are also extracting hot, humid, stale air from doors, windows or through mechanical extraction.

The air movement that is created into the building is in fact another point to be considered in terms of indoor comfort.
This is the reason why together with Temperature and Relative Humidity, Ventilation is a very important factor that has to be considered in the design of an indoor climate control system.

However, if humidity is still an issue, you can still opt for an indirect evaporative cooler, that decreases temperatures using water evaporation, but not adding any moisture to the air.

Evaporative cooling system, health and wellbeing

Evaporative air conditioners are excellent for health

  • They supply 100% fresh, filtered air into your building that is not recirculated, improving Indoor Air Quality (IAQ) of the space, supporting customer and staff well-being
  • Evaporative coolers also require mechanical extraction (or doors and window open, if we consider a small building) to operate. For this reason, if properly installed, they contribute to air dilution. Evaporative coolers never recirculate indoor air, meeting one of the main requirement from worldwide organizations to avoid viruses and germs circulation.
  • They remove unhealthy pollution from your indoor environment: stale air exits the building via windows, doors or extract system.
  • Evaporative cooling systems provide basic moisture that the human body needs; they can assist in reducing the effects of illnesses such as asthma.
  • They remove static electricity.

SPOT COOLING vs General cooling

Often, in large industrial buildings, there are locations inside the plant where heat is concentrated for a variety of reasons. It might be a furnace operation, part of a painting process, concentration of people or a cluster of injection moulding machines.

In all these cases, when you do not need to air condition the whole building, you only need that particular spot to be more comfortable. Spot cooling with an evaporative cooler can dramatically improve the conditions in a set location and the productivity of the plant. In the meantime it costs much less than refrigerated air conditioning. You can contact one of our representatives by clicking here for further information and advice on system design.

If you need to spot cool any of the hot spots in your factory or commercial building, you can opt for any of our Direct Evaporative Cooling solutions, Breezair and Coolair.
