Solar Projects |
| Flaenergy (Healey & Associates) is involved in the variety of
solar projects featured at this web site. Our role typically involves
developing the design and associated construction documents, plans,
and specifications, and providing project oversight to ensure successful
installation.
Recent projects include the design and commissioning of a Solar Desiccant Regeneration system for the Film Storage Building at Kennedy Space Center which is used to store historical documents in a cool storage facility for safekeeping. A solar thermal pilot project was installed at the film storage building at Kennedy Space Center (KSC), Florida, funded by a grant from the Department of Energy's (DOE) Federal Energy Management Program (FEMP). The project demonstrated that sunlight is a viable source of heat for the regeneration process of a desiccant dehumidification system.
Climate control is maintained in the cold storage compartment by
two redundant seven-ton Direct Expansion (DX) air conditioning units.
Each HVAC system includes a desiccant dehumidification package unit.
The DX units provide for the cooling, while the desiccant dehumidification
units control the relative humidity of the conditioned space. The
units are configured to operate in a lead/lag scenario, providing
a reliable system. The desiccant rotates into the air stream to remove moisture and
then rotates out for regeneration. Heat is required in the regeneration
process to evaporate the moisture from the desiccant. The unit uses
a two-stage 19 kilowatt electrical heating element to create 275°F
regeneration air that in turn is blown over the moist desiccant, causing
the moisture to be evaporated and then exhausted to the outside air.
The focus of the project was to offset the electrical consumption
of the existing 19 kilowatt heating elements with solar energy. Because
of the high temperatures required for the regeneration air, high efficiency
evacuated tube solar collectors (Thermomax Mazdon 20) were chosen
for this project. The solar heating system includes 10 evacuated tube collectors mounted on a ground-level stand, a heat exchanger, and a circulation pump. The circulation pump provides heated water to a water-to-air exchanger during daytime operations. To protect against freeze damage, a mixture of 20 percent glycol and 80 percent water was chosen as the operating fluid, with pressure relief valves and an expansion tank included in the system. The entire system is insulated for safety and to ensure maximum efficiency. The installation did not interfere with the existing HVAC equipment and created a redundant heating system for the regeneration equipment during the peak sun hours of a typical day. Other PV solar pv applications include PV Water Pumping in the Everglades, PV for Island Homes; Commercial Pool Heating; Water Heating; Specialized Photovoltaic Systems; and Refurbishment of Poorly Performing Renewable Energy Systems and numerous feasibility studies for C&I Facility Managers.

A variety of cost effective solar applications for
commercial, institutional, and industrial applications are today
reducing operating budgets and helping to preserve the
environment. These "Fact Sheets" are designed
to introduce some of these cost effective commercially
available technologies.
In addition to the fact sheets on solar applications, informational notes on the cost and value of solar and the Business Energy Tax Credit that is available for solar investments. The intent of this information is to assist you in fully evaluating the solar option for your business.
