Air Conditioning for your Brain?

Does Yawning Cool Off Your Cranium?

Cooper Oates Air Conditioning Cooling your BrainMaryland and Princeton University scientists have published in the Journal of Medical Hypothesis that we yawn to air condition our brains. “Brains, like computers, operate best when they are cool,” the authors said.  If that is true, then I have been to some industry meeting lately where most of the brains in the room where getting really chilly.  READ MORE HERE

Game Changing Technology: Transformative Wave’s Catalyst Roof Top RTU Energy Solution

Catalyst RTU Solution by Transformative WaveMore Than A VFD, Transformative Wave’s CATALYST Verified as Powerful New Way to Save Energy with Rooftop HVAC Units.

Most commercial buildings are cooled by packaged rooftop units (RTUs), but RTUs have a problem: Their fans run at full power, even when cooling demands are low. A few years ago, retrofit kits – like Catalyst – hit the market. These kits enabled building operators to upgrade their existing single-zone RTUs to variable-air-volume operation with claimed HVAC savings of 25 to 50 percent.

Originally, these claims were greeted with much skepticism, but independent tests keep bearing out vendor assertions. In 2013, US Dept. of Energy’s Advanced Rooftop Control (ARC) Retrofit: Field-Test Results (PDF) verified savings and demonstrated that these products- especially Transformative Wave’s Catalyst – are ready for prime time.

Game Changing Technology – VRF

VRF: An Energy Slashing HVAC System on the Rise

Variable Refrigerant Flow (VRF) also known as a Variable Refrigerant Volume (VRV) HVAC systems are becoming an important HVAC solution in the U.S. VRF’s make up about 24% of the global commercial air conditioning market and over 35% market share in China, India, and Eastern Europe. USA only represents about 3% of the market, but it is growing rapidly with multiple manufacturers like LG, Daikin, Carrier, Mitsubishi and Sanyo.

A VRF system allows one outdoor condensing unit to be connected to multiple indoor fan-coil units, each individually controllable by its user, while modulating the amount of refrigerant being sent to each evaporator. By operating at varying speeds, VRF units work only at the needed rate allowing for substantial energy savings at partial-load conditions.

VRF systems have some distinct advantages over conventional systems but they are not for every situation or  application. Learn more about this growing and innovative HVAC solution and review case studies at the end of the article.   READ MORE HERE

Editors Note: We are seeing greater demand for this technology due to life-cycle cost benefits and occupant comfort benefits that outweigh the higher first-cost as compared to conventional systems.

110 Years of Modern Air Conditioning

It started as an invention to control humidity in a New York printing plant in 1902 and turned into technology that forever changed the way people around the world live, work and play. July 17th marks the 110th anniversary of the invention of modern air conditioning by Dr. Willis H. Carrier, inventor and founder of Carrier.

On July 17, 1902, Carrier, a young research engineer just a year out of Cornell University, finalized the design to stabilize the humidity in the air so the dimensions of the paper at the Sackett & Wilhelms Lithography and Printing Company in Brooklyn, N.Y., would remain constant throughout the printing process.

Since then modern air conditioning has been applied to everything from malls to manufacturing facilities, buses to businesses and houses to hospitals.

“In the early 1900s, air conditioning was primarily an industrial application that enabled countless industries to thrive with candy-making companies, textile mills and theaters some of the most enthusiastic early adopters,” says Geraud Darnis, president & CEO, UTC Climate, Controls & Security. “Over the years, Carrier’s innovations looked to make possible what was previously impossible. Today our focus remains true to our heritage as we continually push the envelope to create energy efficient, environmentally responsible products for both commercial and residential applications in all areas of the world.”

A leading engineer of his time, Carrier filed more than 80 patents over the course of his career.

“At 25 years old, Willis Carrier’s foresight forever changed the world and paved the way for more than a century of once-impossible innovations,” Darnis said. “His genius created an entire industry essential to global productivity and personal comfort.”
