We all know : with the climate changes, little of durable solutions available to the industry of hvac. condensers are today ill-suited to the extremes of temperature to which they are exposed. The traditional solutions are no longer the case.
So what to do ? In this article, Cool Roof meets the hvac. Keep reading to learn more about our solutions and their sustainability in the face of the challenges and issues facing the refrigeration in the summer.
Most condensers/chillers installed on buildings (including industrial, commercial, logistics) are designed for ambient temperatures of 32°.
However, the heat waves are longer and more intense. In this context, the equipment refrigeration undergo temperatures often exceeding 40°C. These effects of overheating are enhanced by environments with high minerals (roofing bitumen, walls of concrete or steel) that absorbs excessive heat from the sun.
This causes every summer of “cold sweat” for the hvac. In Cool Roof, we’re here for you, hvac, to address those, ” cold sweats ” summer with our solutions simple, simple and innovative of cool roofing.
The solution is the most commonly recommended is the watering and under-face of the condenser. The main problem of this solution — which is not, as we shall see — is its ecological impact is devastating on the fresh water resources. On the other hand, it causes the cost of maintenance and replacement high on your equipment. In fact, this method of cooling is known to degrade potentially the fins of the condenser.
The other solution is often recommended is the increase of the exchange surface of the condenser… But this other ” false solution ” causes a CAPEX most important… once Again, a solution that is not conducive to ” cold sweats, ” this time for your DAF !
By creating a ” island of freshness ” around the condensers through a reflective paints as the CoolRoof that we offer, it is reduced naturally and passively — that is to say, without energy consumption no — heat surface of 30°C, so the heat experienced at the height of the condenser (up to 5°C).
In fact, the solution of the cool roofing limit the risk of maintenance, malfunction, or even break irreversible.
For example, in the summer of 2020, the teams of Cool Roof France have created such islets of freshness (in contrast to the urban heat islands), with their solution coating CoolRoof BaseCoat + TopCoat around more than a hundred of condensers in France. These are our friends, hvac assured !
According to the clients Cool Roof France, 100% of the condensers and protected remained fully functional on the season.
And the co-benefits of cool roofing are numerous : extend the life of the waterproofing membrane, the preservation of the insulation, improving the indoor comfort…
