Solar Air Heating for Water Heaters
Water
heating for domestic use, building heating and air conditioning,
and industrial processes is one of the largest energy expenses for
buildings and facilities. Domestic water heaters supply kitchens,
laundries, rest rooms, sinks in janitor closets, etc. Buildings
often use hot water for cold areas and to reheat air that is "deep
cooled" for air conditioning. Industrial processes heat water
for thousands of industrial activities.
Water
coming from wells or city water mains normally enters a building
at 40 to 60 degrees F. Traditional domestic water heaters will boost
water temperatures at sinks to 105 to 120 degrees F. "Reheat"
hot water for air conditioning systems must generally be delivered
at temperatures above 100 degrees F to be effective. Industrial
processes operate at a variety of temperatures, but usually supply
"make up" water, lost in the process, from cold well or
city water, which must be heated to the operating temperature.
With
the American Solar thermal tile system, building operators can preheat
the water coming into their buildings. This reduces the energy use
in the traditional water heater.
For
large water heating systems, American Solar designs a system that
best fits the size of the building and the water heating loads.
ASI designs and installs an air-to-water heat exchanger and water
storage tank to fit the spaces available and the daily and seasonal
loads. For systems with smaller commercial water tank, American
Solar provides a single unit water preheat and storage tank to handle
the heating and storage needs.
American
Solar also designs systems that take advantage of available summer
heat capacity from the solar tile system, when reduced space heating
demands free up solar heating capacity for additional water heating
loads.
