Passive solar concepts for multistory buildings

Description: Multistory buildings long in the east-west direction and short in the north-south direction offer good opportunity for passive solar application. If each unit within the building is designed so that the Solar Savings Fraction is the same, each will respond to the weather the same way and no unit-to-unit heat distribution is needed. A numerical example for Denver is given indicating excellent thermal performance and a several-day thermal response time. Solutions involving distribution of heat fr… more

Modifications for geothermal-heating system for Kingswood Apartments, Klamath Falls, Oregon

Description: The Kingswood Apartments, located on Eberlein Street in Klamath Falls, are currently heated by a geothermal well producing 118/sup 0/F water. Geothermal water from the well is piped directly through fan coil units in each of the 117 apartments and disposed of in the storm sewer system. Since the installation of the system in 1975, a large number of corrosion failures of the finned tube coils have occured with increasing frequency. This corrosion is probably the result of small concentrations of… more

Trade Study on Aggregation of Multiple 10-KW Solid Ozide Fuel Cell Power Modules

Description: According to the Solid State Energy Conversion Alliance (SECA) program guidelines, solid oxide fuel cells (SOFC) will be produced in the form of 3-10 kW modules for residential use. In addition to residential use, these modules can also be used in apartment buildings, hospitals, etc., where a higher power rating would be required. For example, a hospital might require a 250 kW power generating capacity. To provide this power using the SECA SOFC modules, 25 of the 10 kW modules would be required… more
