SeasonFlow™ Design Fabric Air Diffusers

sioux-falls-hvac

SeasonFlow™ air diffusers can redirect air from the top of the diffuser to the bottom. The result is a diffuser that can be used for hot/cold weather make-up air applications. Using all of your building’s stratified wasted heat before any additional fuel is burned can provide substantial savings during the heating season and helps improve air circulation throughout the workplace.

Customize Your Look for Less

sioux-falls-hvac

Custom logos may be something that is not even considered for sheet metal duct but with fabric air diffuser systems you have that option. The possibility of adding extra color or a logo to a room can customize the application even further. Many schools, car dealerships, and businesses have done this and have loved the outcome. Of course, there is an added cost, but the entire system will still be less than sheet metal duct.

The Dunham-Bush FC Series

sioux-falls-hvac

CONCEPT

Free cooling is an economical method of using low external air temperatures to assist in chilling water, which can then be used for air conditioning systems. It is the production of chilled water without the use of a chiller and can be used generally in the late fall, winter and early spring.

When the ambient air temperature drops to a set temperature, a modulating valve allows all or part of the chilled water to by-pass an existing chiller and run through the Free Cooling system, which uses less power and uses the lower ambient air temperature to cool the water in the system.

OPERATION

Ambient Temperature above 40ºF

When the process return water temperature required is equal to or higher than the ambient air temperature, Free Cooling is not suitable. The system’s three-way valve will continue to direct the fluid flow through the chiller’s compressors to be cooled to the required set point temperature.

Mid Ambient (Between 15ºF to 40ºF)

The water is partially cooled by the compressor and partially by the ambient temperatures. The percentage of Free Cooling achieved is dependent on seasonal temperatures, although partial Free Cooling commences when the ambient temperature reached 32ºF. The water is partially cooled through the Free Cooler then flows through the chiller’s compressors to achieve the required set point temperature.

Low Ambient (Below 15ºF)

When outdoor temperatures are low enough, the water is chilled solely by the Free Cooling coil. This allows the chiller’s compressors to stop operating, saving significant amounts of energy. The only electrical power used in winter operation is for fan operation.

Notes: The operating sequence above serves as a general guideline only. The ambient temperature for free cooling to commence can be reset by user.

NEW from Price

sioux-falls-hvac

Price is pleased to announce the upcoming release of our redesigned series fan powered box. The redesigned FDC will be available in June, 2017.

This new fan powered box will appear in All In One as ‘FDC-G2’ and will replace the current FDC model. The ‘FDC-G2’ with inlet attenuator (IAS) will replace the current FDCA2 model. To aid in transitioning to the new model, the current FDC and FDCA2 will be available in AIO until September, 2017. After September, the FDC and FDCA2 models will be removed from AIO, however, they will still be available to order as a special.

Some highlights of the new FDC-G2 include:

  • Reduced footprint
  • Full-sized access panels on top and bottom
  • Field-reversible between LH and RH orientations, including units with water coils and electric coils
  • Factory-installed attenuator to reduce installation time

For your information, a preliminary submittal of the new FDC-G2 is available here. For additional information, please contact the Air Moving applications team at airmovement@priceindustries.com.

4 Technologies Driving Energy Efficiency Jobs

sioux-falls-hvac

When you think of energy jobs, you may first picture someone fixing a wind turbine or installing a solar panel. These jobs are certainly on the rise. But as businesses and home owners increasingly seek cost savings on their utility bills, a large portion of energy jobs today — almost a third, in fact — are focused on efficiency.

More than 133,000 energy efficiency jobs were added in 2016, bringing the total number of Americans working in the sector to 2.2 million people. More than half of those jobs (1.4 million) are in the construction industry alone. Whether it’s construction, manufacturing, or wholesale trade, much of this job growth has been driven by four technology areas.

Efficient Appliances

More than a quarter of the energy efficiency workforce (552,000 workers) is related to efficient appliances, including high-efficiency heating and cooling equipment. That’s a 58% increase from 2015. U.S. Department of Energy (DOE) support continues to push the envelope on innovation across a range of common appliances – from high-performance refrigerators to more efficient air conditioners – with the ultimate goal of keeping more money in consumers’ pockets.

HVAC

Another 25% of the energy efficiency workforce is employed in the traditional HVAC industry. While these 520,000 workers spend a majority of their time working with conventional heating and cooling services, part of their work is also dedicated to high-efficiency technologies.

Advanced Building Materials

Innovation has driven significant progress in reducing the energy consumption of buildings and homes, including technology advancements like next-generation windows and building envelope technologies. Better insulation and more efficient windows reduce the energy needed to heat and cool homes and commercial buildings. This saves money on utility bills and keeps occupants more comfortable.

These advancements also mean more job opportunities. Last year, 446,000 workers were employed in roles related to advanced building materials. DOE-backed research continues to develop new materials and methods to improve insulation and windows, including innovative sprayable insulation and new smart window coatings.

Lighting

Another 327,000 workers are employed in the energy-efficient lighting industry.

DOE-backed research in solid-state lighting has yielded more than 260 patents and a significant industry footprint, with literally millions of products currently on the market based, at least in part, on these technical advancements. These products are estimated to have contributed to more than $2.8 billion in savings for consumers and businesses – an impressive return on an investment of about $350 million.

NEW Lab Exhaust Direct Drive Options

sioux-falls-hvac

Greenheck’’s Vektor® line of laboratory exhaust systems now offers a direct drive arrangement 4 option available on Vektor-MH (High Plume), Vektor-MD (High Plume with Dilution) and Vektor-MS (Variable Geometry Nozzle) models.

The design combines a lightweight, aluminum mixed flow wheel with an industrial grade motor to provide low vibration and efficient operation. Maintenance is reduced as the motor does not require lubrication for up to one year, and, if necessary, the motor can be safely serviced through a bifurcated opening without disassembling the fan.
