The phase-out of HFC’s (Freon or Hydrofluorocarbons) is a measure designed to gradually reduce the impact of refrigerants on the atmosphere’s ozone layer. These substances are widely used in the HVAC sector, but also in domestic and industrial refrigeration (fridges, freezers etc.).
The decision to use R32 as the refrigerant gas in future air conditioning systems has become an ongoing, controversial debate. Some producers have embraced the switch to this gas, which has a very low GWP (Global Warming Potential), while others continue to delay this change which now seems inevitable.
The IIoT (Industrial Internet of Things) is a special subcategory of the Internet of Things (IoT), used in the industrial sector. It involves equipment and analysis platforms which are connected to the internet, environmental sensors, complex industrial robots and much more.
Although less severe than the impact on other sectors, the impact of the coronavirus on the HVAC sector in the EU and USA has become apparent. There have been slowdowns, losses and unexpected issues, but just about every country has managed to find a strategy to limit the damage caused by Covid-19.
Covid’s impact on the environment seems to have had both positive and negative effects: on the one hand, the lockdown brought a temporary cease in the emission of greenhouse gases into the atmosphere (especially in large industrialised cities), while, on the other hand, it provided some sectors with a chance to try and get around restrictions set out in pollution legislation.
In this article, in a very simplified way, we see what is meant by free cooling, and how it can be a valid alternative, convenient under the right conditions.Free cooling is a special cooling method which uses external temperatures to dissipate the heat inside a closed system. It is a very efficient solution which, if used in the right environments, can result in considerable savings.
The anti-coronavirus tracking apps developed by several countries have become a subject of debate and some consternation among many people who feel threatened by them and who are voicing their concern. However, this reaction is often based on a lack of real knowledge of how such systems work and the objectives of the software.
The correlation between the summer season, air conditioning and the coronavirus is currently a hot topic. With summer just around the corner, many people have started to wonder how the use of air conditioning systems might affect the spread of Covid-19.
Mechanical controlled ventilation is a design feature which enables building to keep the air clean and conditioned, without significant energy consumption. These devices have a decisive effect on the quality and comfort of the atmosphere in a building, especially for those living in cities where smog is an ever-present problem.
The dilemma of replacement versus repair when shell and tube heat exchangers encounter operational problems is quite common. Such devices are quite delicate and in order to work properly, it is essential that their structure is in perfect condition and there are no defects.
