Technology & Trends - Heat Recovery Ventilators (HRV)

This year’s Clean Air Day falls on Friday the 19th June.  In its eighth year, Clean Air Day has become the UK’s largest campaign dedicated to raising awareness of air pollution and its impacts on health and the environment. It also encourages individuals and organizations to take practical steps to reduce pollution and protect public health, both inside and outside buildings. Air quality should be a concern for everyone, but certain sections of society are disproportionally imp...

Every six years, the United States Department of Energy (DOE) reviews how much energy certain home appliances and mechanical systems use and determines if an increase in energy efficiency requirements is justified. New energy conservation standards As a result of the 2017 assessment, the DOE has mandated new energy conservation standards that take effect on January 1, 2023, for all newly manufactured residential and commercial air conditioners, heat pumps, and gas furnaces.  In addition t...

Over the last decades heating, ventilation, and air-conditioning systems became significantly more energy efficient. This is immensely important as they are one of the largest energy-consuming loads in commercial and residential buildings. Smooth performance of the systems requires careful installation, thorough cleaning, and regular maintenance. Running an HVAC system (energy) efficiently is challenging because of constantly changing variables: people entering and leaving a building, changing...

Most people spend about 90 percent of their time indoors. For home owners, indoor environmental quality (IEQ) is the most meaningful differentiator between ‘high-performance’ and ‘code-built’ homes. Indoor environmental quality  IEQ describes how well the indoor environment promotes occupant comfort and health. The components of IEQ include thermal comfort, indoor air quality (IAQ), sound and lighting. Requirements for optimal IEQ vary per occupant and household, d...

With ongoing efforts from governments across the globe to reduce carbon emissions and with an ever greater focus on sustainability, it is vital that the HVAC sector does its part in becoming more environmentally conscious. And, while there have been steps to become more sustainable, there is a huge amount that still needs to be done to make sure that many of the targets that have been set are attainable. In buildings, both large and small, industrial heating accounts for roughly two thirds of i...

With the roadmap laid out for the government to guide us out of lockdown, the end of the pandemic seems as though it could be in sight. However, HVAC units remain outdated in hotels, hospitals, schools, and offices and there is a worry that COVID-19 can still spread quickly and easily through air vents, mitigating the effects of lockdowns and vaccinations. Dr. Rhys Thomas, Chief Scientific Officer at infection mitigation specialist PP-L and a frontline NHS doctor, says that the government&rsquo...

The modern technological world is filled with ‘extrusions’. They are all around us, in the form of small and not-so-small cross sections. The function of an extrusion is to form seals between components of complex machinery and keep them functional. And, depending on the ‘type’ used, they can make a big difference to how a machine operates. Some of the most desirable types of extrusion — and especially for use in HVAC systems — are those made from silicone. S...
