| 520 | |a"The primary purpose of this project was to determine if furnace heat exchangers were prematurely or excessively rusting due to condensation when fresh air ducts are hard connected to the return air system. In addition, occupants were to be interviewed to ascertain whether such systems were causing cool drafts. The energy impact of this type of ventilation system and the practicality of installing high inside wall supply outlets was also to be investigated. A test house was to be set-up to measure air flows, temperatures and pressures during various modes of ventilation system operation"--Exec. Summary. |
