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.
High-efficiency super capacity chiller system successfully completes certification tests
May 8, 2017
The U.S. Navy has successfully completed final production prototype shock and vibration testing for the new-generation high-efficiency super capacity (HESC) chiller system, consisting of the HESC chiller and the HESC variable speed drive (VSD), which integrates key components from Calnetix Technologies.
New system handles daytime temperature and nighttime humidity with a single system
April 17, 2017
As the movement to legalize marijuana continues to take hold across the country, growers are beginning to seek out equipment that will help them maximize production. Until recently, there were no cooling and drying products specifically designed to optimize growing conditions for this agricultural product. Now, new technology is being engineered that can produce the right temperature and humidity conditions to maximize productivity and minimize mold and insect problems.
Researchers must look beyond nonflammable chemicals
April 3, 2017
NIST’s study, entitled “Limited options for low-global warming potential [GWP] refrigerants,” focused on residential and small-commercial single-package and split air conditioning systems, but the authors said their conclusions also generally apply to room air conditioning units and other refrigeration and heat-pump systems currently using common, ozone-depleting refrigerants such as R-410A or R-22, which are still used in some developing countries today. “The takeaway is there is no perfect, easy replacement for current refrigerants,” NIST chemical engineer Mark McLinden said.
Facility managers face critical decisions when replacing aging induction units
March 20, 2017
As old induction units inevitably decline in efficiency, facility owners and managers are faced with critical decisions: upgrade to more modern induction units or embark on extensive, costly renovation projects to overhaul entire HVAC systems.
Advantages of adiabatic humidification and free air cooling
March 6, 2017
Proper indoor air quality and adequate humidity levels are imperative to safe and efficient data center operations. Humidification in data centers is required to prevent electrostatic discharge, which can damage servers and network products, and offers the benefit of high capacity, low cost evaporative cooling.
The Luigi Pecci Centre for Contemporary Art once again reopened
February 20, 2017
The new Pecci Centre is innovative not only from an architectural point of view, but also in terms of its sustainable mechanical systems.
The lighting and air conditioning systems, which are the main energy expenditure in every kind of building, have been designed to offer the best internal comfort for the visitors of the centre, while guaranteeing minimal impact both on the running costs and on the environment.
RGF’s Reme Halo air purification unit and IMSB Ice Machine Sanitizer were tested for three months in multiple Chipotle locations. Impressive results that were independently verified and validated led to the decision to incorporate RGF technology into Chipotle’s entire customer safety strategy.
HVAC contractors poised to reap benefits as Wi-Fi enabled thermostat prices drop
January 23, 2017
Despite the availability of quality Wi-Fi enabled products from leading thermostat manufacturers, a mere 10 to 15 percent of residential and light commercial installations involve such models. The primary objection: a wholesale price point that is four to five times the cost of a traditional thermostat.
When you’re looking to heat one area of a building or home with cold spots, consider spot heating options. Cold spots that need heat include areas that may not have been included when the HVAC system was installed, such as new additions or spaces that were simply overlooked.
