How to keep cool in industrial buildings?
As the heat wave that summer rages around the world, the question arises - how to cool your energy-intensive buildings, while reducing energy bills and fighting global warming?
There are technologies such as paint cooling or air conditioning without air conditioning.
The world is breaking heat records. In Europe, the temperature in different places exceeded 40 °C. On the territory of the European part of Russia, the summer has been quite hot for many years. Industrial buildings are overheating, and manufacturers are looking for ways to cool them without increasing energy bills and exacerbating global warming. Fortunately, solutions exist. Data centers, industrial facilities, logistics platforms, warehouses and even ordinary supermarkets and shops can benefit from this.
Solar Paint
The French company SOLAR PAINT has developed SOLARCOAT®, a reflective paint capable of cooling the interior of buildings. The process is to cover the roofs with this white reflective paint. This paint has a sunlight reflection coefficient of more than 92%, which reduces the temperature inside buildings by an average of 5°C and thus limits the need for air conditioning in summer. After all, the solution helps to reduce the electricity bill.
According to SOLAR PAINT, if the building is repainted with SOLARCOAT® paint, it can dramatically reduce the use of air conditioners inside in summer and achieve energy savings of up to 30%.
What does SOLARCOAT® consist of? The composition of this water-based paint includes natural ingredients and recycled materials such as broken glass.
Air conditioning without air conditioning
The Italian company SINTRA has been producing environmentally friendly air treatment solutions for 30 years in order to make buildings non-volatile. They came up with an HVAC system that replaces artificial air conditioning with free, natural and eco-friendly.
How does it work? The SINTRA system is based on two types of innovative perforated air ducts: Spirojet air ducts and MIX-IND air ducts.
The air ducts of the Spirojet, consisting of several meter modules, disperse the supply air through dozens of small holes, like a diffuser with high induction. The result: good air diffusion in the building and continuous ventilation without condensation at a competitive price.
With the MIX-IND series of perforated air ducts, also called PULSEURS air ducts, SINTRA takes another step forward. The solution that "pulsates" the surrounding air directly solves the problems of overheating of industrial buildings with large heights and areas.
The idea is to introduce a large mass of air into the building at the lowest outdoor temperature, for example, at night. Then the energy contained in this fresh air is preserved due to the thermal inertia of the building structures (floor, walls ...). This air can then be used during the day when it is most needed, thanks to reinforced insulation and the use of sunscreens on the walls and roof.
In fact, a cold watt is supplied at night to use it during the day. Consequently, the cost of installing an air conditioner is reduced, because there is simply no count. But with this system, the temperature inside the building is lower than if an artificial air conditioning system was installed! The temperature inside the building ranges from 21 to 25 °, even when it is very hot and there is natural excessive ventilation.
Thanks to these two technologies, SINTRA boasts high energy performance and maximum uniformity throughout the building, even with large volumes.
