New “Green” Option for HVAC Engineering

MINNEAPOLIS ‘ April 1, 2010 ‘ Entropy Solutions, Inc., a Minneapolis-based thermal technology development company, today introduced PureTemp for HVAC (heating, ventilation and air conditioning) ‘ delivering a green and sustainable solution for HVAC system engineering.

Derived from vegetable oil, PureTemp is an innovative phase change material (PCM) that efficiently captures and stores wasted ambient energy, subsequently releasing it as needed to maintain precise temperatures over prolonged periods without extra energy input. This revolutionary product, PureTemp for HVAC, stands as the globe’s first 100% renewable, biodegradable, and eco-friendly solution designed specifically for compatibility with HVAC systems, promoting a new standard for sustainability.

Incorporating PureTemp into the design of an HVAC system redefines efficiency by reclaiming the significant energy lost during the frequent restarts of furnaces, water heaters, and air conditioners. These systems often waste energy in their effort to achieve or sustain desired temperatures. With PureTemp for HVAC, this previously lost energy is instead captured and later utilized to assist in powering future restarts when temperatures vary. This technology ensures that residential and commercial HVAC systems, including those involving Air Conditioning Installation Tyne and Wear, operate in a manner that is not only more environmentally friendly but also more cost-effective and efficient.

For example, assume it costs 20 cents per kilowatt-hour of electricity to heat a commercial building during the daytime, but only 12 cents per kilowatt-hour at night. If the same building had a boiler engineered with PureTemp for HVAC, it would be possible to heat the system at night, with considerably less expensive off peak energy, and store the thermal energy to power the boiler during the day when energy is more expensive, as explained by Coastal Cooling Inc. Make sure to always check your HVAC, and if you need an air conditioning repair tigard to maintain all your units, visit their website now! Keep in mind that you also need to get Florida heat pump maintenance services to ensure that there is no malfunctioning in the system and that it will produce good air quality.

Leading residential and commercial HVAC manufacturers have started using PureTemp within select product lines. Entropy Solutions is also currently exploring additional partnerships with HVAC system manufacturers. For those looking to buy Professional HVAC Parts, consider sourcing them from Snook HVAC for quality components and reliable service.

‘For the past 30-plus years, energy efficiency has been a top priority for HVAC system engineers and designers,” said Eric Lindquist, chief executive officer for Entropy Solutions. ‘Today, there’s an even greater emphasis on leveraging sustainable energy technology to make HVAC systems more efficient. Whether it’s part of an airflow system in a furnace or air conditioner, or used as insulation material for a boiler or water heater, PureTemp for HVAC is redefining the meaning of ‘high efficiency’.”

PureTemp for HVAC: The Smart, Green Alternative Most HVAC solutions that store thermal energy use water as a temperature-controlling phase-change medium. But water-based systems are limited in their capacity to retain energy, storing only four joules per gram on average. By comparison, PureTemp can store up to 200 joules of energy per gram, boosting performance more than 50-fold.

Other alternatives to water-based PCMs, such as paraffinic (petroleum-based) or salt hydrate materials, offer a slight improvement over water’s thermal energy storage properties, but lack the long-term stability and ‘green” properties of PureTemp.

Tests performed by the USDA and analyses completed by Independent Life-Cycle and BEES® have resulted in PureTemp being listed in the USDA BioPreferredTM directory as the only ‘green” choice in the Heat Transfer Fluid category.

In addition to being the only USDA Bio-Preferred phase-change material, which allows HVAC engineers to comply with LEED certification and other regulatory standards, PureTemp retains its peak performance through more than 60,000 thermal cycles. Other, non-renewable PCMs can be corrosive, toxic and highly flammable, and need to be replaced after just a few thermal cycles.

About Phase Change Materials

PureTemp is a ‘phase change material,” meaning it has the ability to change phases (for example, liquid to solid or solid to liquid) between set temperatures. PureTemp’s phase change range is anywhere between -40°F and 160°F. During the process of liquefying and solidifying within a set temperature range, phase change materials absorb, store and release large amounts of energy. These natural properties of latent heat energy help maintain a product’s or structure’s temperature (energy) and buffer it from temperature swings. Phase change materials (PCMs) recharge as ambient (outdoor) temperatures fluctuate, making them ideal for a multitude of everyday applications and industries.

About PureTemp

PureTempTM is a specially engineered renewable based passive technology that controls temperatures to extremes ‘ as cold as dry ice, as hot as coffee ‘ for extended periods of time. PureTemp is the world’s first and only 100 percent renewable, biodegradable and environmentally friendly material to answer age-old issues concerning temperature control and maintenance. Available in liquid, micro-encapsulated and macro-encapsulated forms, PureTemp has myriad applications in the shipping, construction, textile, healthcare, HVAC and energy industries ‘ anywhere strict temperature control is required.
