Comboflair(reg) Space Conditioning, Water Heating and Air Distribution System for HUD Code Manufactured Housing. Project Report.

摘要

There are over 8 million manufactured homes in the United States or 7.5 percent of the total housing stock occupied by over 7 percent of the U.S. population. Only 10 States contain 50 percent of all manufactured housing units. These states include 8 Southern States, Michigan and California. In 2006, the manufactured housing industry shipped approximately 117,300 units nationwide of which over 58 percent were shipped to Southern States. Manufactured homes provide affordable housing. In the Year 2005, the average price of a 1,725 sq. ft. home was $68,600 or $39.77 per square feet compared to $90.63 per square feet (excluding land costs) for a site-built home. While the quality of the structural components of manufactured homes continues to improve, there have been no improvements to comfort conditions or the efficiency of HVAC systems in these homes. The need for improved space conditioning systems was identified by the manufactured housing industry and by the U.S. Department of Energy under its Building America Program. Recognizing the need for new space conditioning and water heating systems for manufactured housing, DeLima Associates assembled a team to develop a space conditioning system that would enhance comfort conditions while also reducing energy usage at the systems level.
