More often than not, filters are being changed too late
May 22, 2017
Where clean air is needed, an air filter is usually not far away. In the last decade, the filtration industry has made tremendous progress in filter technologies. With new materials and designs, advances in nonwoven fabric manufacturing, and pleating methods, as well as new developments like nanofiber layers and coatings, filters have become more efficient, reliable, and compact. Demands on the filtration industry are also changing. It’s no longer solely about filter efficiency and dust-holding capacity; with soaring energy prices and increasing awareness of sustainability, filter media are expected to contribute to lower energy consumption.
Rooftop systems, air handlers, heat pumps, VRF systems and more
May 8, 2017
Like last year, this year’s Cooling Showcase is split into two parts — commercial and residential. This issue focuses on the commercial side of the air conditioning industry while the April 17 issue highlighted new offerings in the residential cooling market. Included in this coverage is feature-specific information about each product as submitted by the manufacturers.
Originally designed to support an occupancy level of 850 people, the Arcbest corporate headquarters has grown to now have 1,085 people plus visitors. Ten percent of the people work at night, requiring 24/7 air conditioning. The increase in occupancy drove a need to introduce more outside air to maintain air quality. All of this outside air had to be conditioned, increasing electrical energy costs. In addition, the extra outside air caused draftiness on cold winter days, and, during the summer, the extra outside air flow through the air handlers resulted in some parts of the building getting too cool.
Habitat for Humanity (HH) and RGF Environmental Group Inc. (RGF) announced that they will cooperate on a strategic partnership to raise funds for building Habitat homes. Through the Halos for Homes partnership, RGF will donate a portion of sales from its most popular IAQ products, the REME HALO In-Duct Air Purifier, BLU QR UV stick light, Quad-DM Ion Generator for In-Duct HVAC units, and the Quad-MS® Ion Generator for Mini Split units from April 1 through Dec. 1.
HLR technology achieves superior IAQ to boost student performance
April 25, 2017
enVerid Systems Inc. announced that the Shanghai-based China Europe International Business School (CEIBS) has achieved superior indoor air quality per the U.S. Environmental Protection Agency (EPA) standards, and 80 percent reduction in the utilization of outside air, through the installation of enVerid HLR® (HVAC Load Reduction) modules in its state-of-the-art lecture theater.
While proper ventilation can sell itself for those who suffer from allergies, it can be a more difficult sell to the rest of the population. Many homeowners are more concerned with ensuring their HVAC system is keeping a consistent temperature than maintaining indoor air quality (IAQ). But, in recent years, more and more studies are linking health issues with indoor air pollution. By making homeowners aware of these results, you can help them make an informed decisions for proper ventilation and air quality improvements.
IQAir announced its clean air technology is now featured in the new Vitality Room of Swissôtel in Zurich, Switzerland. The room was specially designed to be a serene and stylish sanctuary for those concerned about physical and mental well-being. The Vitality Room builds upon Swissôtel's well-received Vitality Program, which takes an integrated approach to supporting guests by focusing on health and wellness.
Boosts energy efficiency and reduces costs in commercial buildings
April 7, 2017
By cleaning and recycling the indoor air instead of constantly replacing it with outside air, enVerid’s HLR system decreases the outside air intake required to ventilate a building by 60-80 percent and also reduces peak HVAC capacity, resulting in up to 40 percent lower utility demand charges. Moreover, with HLR technology, buildings can invest in lower-capacity and less expensive HVAC systems and benefit from decreased maintenance costs and extended life of existing equipment.
