HVAC Case Study
Sport Center ADOLFO SUAREZ

Project requirements

Adolfo Suarez Sport Center is situated in Sevilla la Nueva, near Madrid. The gym hosts many athletes, specifically children attending extra-curricular activities.
The new municipality decided to switch to evaporative cooling to improve thermal comfort.

The roof of the building is made of aluminium sandwitch panels with poor insulation during hot summer days. Moreover, the same roof produces a greenhouse effect, multiplying temperatures inside the building. If we add to this the gym’s lights, the windows (with no curtaines) and the athletes’ heat load, the result was that inside the sport center’s temperatures could reach several degrees higher than the outside temperature.

The management solved the heating issue several years ago, by means of a diesel boiler system. Gym air conditioning, instead, was still the great unresolved matter. The center had no other means of mitigation than extractors, which could dissipate part of the heat generated, but not effectively cooling the building.

The Installation of gym air conditioning system Coolair

Australair Ecoclimatización, official distributor of Seeley International products, came up with an interesting solution involving evaporative cooling, suggesting the installation of Coolair direct evaporative coolers.

To cool the 1000 m² building, Australair suggested to install 4 x Coolair CPQ1100X units, with a cooling capacity equivalent to 14.1 kW each unit, air flow of 10,120 m3/h per unit and a maximum consumption of 1.2 kW per element (4 in total). The average water consumption is approximately 30 l/h.

With this installation,  Australair completely solved the problem of air conditioning of the Sports Center. Internal temperatures reach now much more comfortable 25-27 ºC. For what concerns saving in energy costs, the management removed extractors: in fact, they were low efficiency machines with higher energy consumption, compared to Coolair.

Results

With this solution, the Municipality of Seville la Nueva has become a pioneer in the implementation of bioclimatic solutions in public buildings. Gym air conditioning solutions using water like Coolair are the eco-friendly and energy efficient technologies perfect for the job.

Industrial and commercial buildings but also gyms and sport centres, usually have heat issues. Air conditioning might seem the obvious solution, but it is expensive to install and maintain. Moreover, it requires doors and windows to be kept shut. As outside temperatures increase, buildings with inadequate ventilation become unbearably hot and stuffy.

Easy to install and maintain, Coolair evaporative coolers are the best solutions when cooling large and semi-open areas. Running only with water and electricity, they use up to 80% less energy than conventional air conditioning, thus resulting in a significant saving in running costs.

Drawing 100% fresh air from outside, evaporative coolers offer a great health advantage over refrigerated air conditioning, which recirculates the same stale dry air over and over.
