Two reasons HVAC and gender equality needs to be a top priority
In the heating, ventilation and air conditioning (HVAC) industry – and the building sector in general – men are still in a vast majority. And although I wish it looked different, Swegon is no exception. I know we can do better, and I firmly believe a more equal organisation will be a more …Steve Gore
A Guide to Smoke Control Damper Classifications
In a previous blog article we looked at how a Fire Damper is classified, and how to interpret the classification. In this article we will look at how Smoke Control dampers are classified and how to interpret the classification.Timo Schreck
Clearing up a few myths in humidity recovery
There are many assumptions and opinions circulating around humidity recovery in the European HVAC industry and among HVAC engineers. Some of them are based on bad experiences, some of studies or claims presented with a certain partiality. I will try to clarify some these myths based on my …William Lawrance
The many advantages of sorption technology
Air handling units equipped with rotary heat exchangers with a sorption coating bring significant opportunity for energy and carbon emission reductions, while also improving the indoor environment. But what exactly is it that make them so advantageous? Here is a step-by-step guide to understanding …Josh Emerson
Guide to Smoke Control Dampers & Fire Dampers...
This article focuses on providing a brief overview of the key functions, types and correct selection of fire and smoke dampers for ventilation systems to help to improve building safety.Mikael Börjesson
Gender and indoor climate - a blind spot we need to address
Some surprising results in a survey made us think, and findings in recent research suggest a somewhat alarming pattern. It seems we systematically design buildings to suit men, and women are consistently suffering for it. It’s clearly not fair, and we believe it’s time to act upon it.Alessandro Pinato
Cracking the myths about propane
Over the years, EU regulations on synthetic refrigerants like CFC, HCFC and HFC have tightened, severely restricting or even banning their use. And a further tightening is underway with the update of the F-gas regulation which is currently under discussion.Steve Gore
Damper Release Mechanisms
Different words are often used to describe the method of actuation of Fire Dampers. Very often words such as Automatic and Manual are used. ‘Automatic’ is used to describe a damper that has an actuator, and ‘manual’ being used to describe a damper that is activated by a mechanical device such as a …Fabio Polo
Energy analysis for improved efficiency
There are a few ways of evaluating energy usage in heating and cooling applications. They are all valid in their own way, but it is important to remember that they evaluate energy efficiency in different ways and that they should be used in different situations depending on your needs.Tony Pettersson
Demand controlled ventilation leads to energy savings
The citizenM chain of hotels has taken pride in providing luxury comfort in compact rooms. Guests have been provided with control of the indoor climate, which is optimal for both comfort and energy efficiency. Recently, a demand controlled ventilation system from Swegon has decreased energy …By topics
