New Solar-Assisted Residential Heating And Cooling System

Even on days with limited sun exposure, the Lennox SunSource takes advantage of the available solar resources and reduces energy usage. To match the expected gains in energy efficiency, a conventional outdoor residential air conditioning unit would have to almost double in size.

Lennox Industries unveiled SunSource, the industry's first integrated solar-assisted residential heating and cooling system, at the Association of Energy Services Professionals (AESP) 4th Technology Symposium in Long Beach, CA. The system will be available to the public in 2009. Lennox Industries is a subsidiary of Lennox International.

"Lennox is a recognized and respected innovator in the heating and cooling industry, and with the introduction of the Lennox SunSource we are furthering our commitment to innovation and energy efficiency," said Doug Young, president and COO, LII Residential Heating and Cooling.

As photovoltaic solar panels become more affordable, solar power becomes a more viable solution to reducing peak residential energy consumption, reducing energy bills and demand on a capacity-constrained energy grid.

Solar power provides an alternative resource during the hours when air conditioning drives energy demand higher and peak energy relief is needed most. Using a patent-pending technology developed specifically for use in residential applications, the Lennox SunSource can help reduce peak demand, increase energy efficiency, and maintain homeowner comfort.

The Lennox SunSource integrates solar power by using a single 190-watt solar panel which provides power to assist the fan motor that moves air across the outdoor coil, a critical component in any home comfort system.

Even on days with limited sun exposure, the Lennox SunSource takes advantage of the available solar resources and reduces energy usage. To match the expected gains in energy efficiency, a conventional outdoor residential air conditioning unit would have to almost double in size.

Integrating solar power into other components of a typical home comfort system -- including indoor motors, compressors, indoor air quality products, and thermostats -- is currently being evaluated. "The Lennox SunSource is another step towards the acceptance of single-point solar technology applications," said Doug Young.

"This unique application specifically targets reducing peak demand, while improving energy efficiency and maintaining comfort. Together with the electric industry and the support of our outstanding North American dealer network, we can begin to make a significant positive change in 2009."
