Hot weather is getting close!

THE EFFICIENT AND ECO-FRIENDLY SOLUTION TO THE INCOMING HOT SEASON

The Roof Cooler reduces the air temperature thanks to the natural physical phenomenon of evaporation.

Evaporative cooling is a an adiabatic process that happens when the air leaves energy in the form of heat to the water. The water evaporates and the air temperature decreases.

EASY

The Roof Cooler working principle is essentially easy:

  • The outdoor hot air is drew in through the wetted cooling pads.

  • The water inside the wetted cellulose panels evaporates absorbing energy from the hot air and thus reducing the air temperature.

  • The air that was so cooled is then led into the indoor space at a lower temperature thanks to the effect of water evaporation.

The Roof Cooler continuously sends into the indoor space filtered and cooled outdoor fresh air.

It is specific to create a fresh, ventilated, clean and comfortable environment in large areas.

It is ideal for a wide range of commercial, industrial, residential and zootechnical usages.

FUNCTIONING

HOW MUCH DOES THE TEMPERATURE GET REDUCED?

The evaporative cooling efficacy depends directly on the humidity and temperature conditions of inlet air.

This system indeed tends to saturate the inlet air with water vapour, bringing the indoor relative humidity to 90-95%.

The inlet air is cooled and humidified at the same time. So, the more the inlet air is dry, the more the air that is led into the indoor space will be cooled.

This may lead to think that the advantage of decreasing the temperature may be null in the face of humidity increase.

For this purpuse, it is useful to know the concept of perceived heat (a word abused by the media).

According to the Stedman diagram, with decreasing the temperature, the relevance of the humidity level to the perception of heat significantly reduces.

As you can see in the table below, when the temperature of inlet air reaches 27°C, the additional humidity becomes unimportant for the wellness perception.

ECO-FRIENDLY

 

ENVIROMENTALLY FRIENDLY

Without compressor, refrigerant gases and pollutants, it is an energy efficient and environmentally friendly product.

If compared with traditional air conditioning systems it consumes significantly less energy.

Water, a non toxic element, is used as refrigerant and has no impact on the environment.

Easy to install and to manage and with low maintenance costs, the Roof Cooler is the ideal solution to cool big spaces.
