Adsorption chiller captures and uses waste heat

Capturing and using waste heat could be one of the largest conservation and green house gas reduction opportunities available to many of your readers. As you inform readers about energy saving opportunities in the coming months, I would like to make you aware of the role adsorption chillers could play in helping them achieve air conditioning and process cooling by recovering waste heat.


 I represent Power Partners, Inc., which manufactures the ECO-MAX adsorption chiller and sells it in North and South America. ECO-MAX chillers can easily be integrated with tri-generation or CCHP.

Adsorption chillers are driven by hot water rather than by large amounts of electricity like conventional air conditioners. This hot water may come from any number of industrial sources, including waste heat from industrial processes, prime heat from solar thermal installations or from the exhaust or water jacket heat of a piston engine or turbine. Organizations that could benefit from adsorption chillers include food and beverage processing; chemical, plastic, rubber, paper and cement manufacturing; hospitals; hotels; and school campuses.

The heat extracted from the chilled water and the heat consumed from the hot water is directed into a cooling water system used to dissipate this energy. This heat dissipation may occur in a water system; water heat exchanger, a dry water tower or an evaporative (wet) water tower. Very little electric power is consumed running the chiller, generally about the same amount of electricity as a handful of old-fashioned incandescent light bulbs. The electric power used drives the internal process computer, a PLC, (programmable logic controller) and the intermittent running of a fractional horsepower vacuum pump.
Adsorption chillers present a new choice to plant managers and engineers, one that is far better than absorption chillers or mechanical chillers. Compared with absorption chillers, for example, ECO-MAX adsorption chillers:

–Use water rather than lithium bromide, so there are no crystallization problems, no corrosion, no chemical testing, no hazardous leaks and no chemical disposal issues.
–Have low maintenance and operating costs (adsorption chillers need no compressors, so there are no high voltage requirements, no high pressure, no overhaul, no oil changes and only minor service required every three years).
–Are environmentally friendly (exceptionally low carbon emissions, no chemicals and virtually no noise or vibration).
–Operate continuously because there is no need for chemical tests and adjustments, and over a wide temperature range for hot, cool and cold water.

Power Partners (www.eco-maxchillers.com) has prepared a white paper that explains the properties of adsorption chillers and the advantages they provide compared with other types of chillers. I encourage you to read it and get excited about the role such a tool can play in helping readers achieve their green manufacturing and cost reduction goals. The ability to integrate adsorption chillers with tri-generation or CCHP is addressed on page 10. Please let me know if you would like to speak to Power Partners’ marketing team to learn more about ECO-MAX adsorption chillers.
