Impact of the humidity pump on indoor environments. Final report, August 1989-November 1990
The impact of the humidity pump, (a newly developed, gas-fired, liquid desiccant, make-up air conditioning unit) on the indoor air environment of two office buildings was investigated during a two month field program. The study generated a data base and gained insights on indoor air quality (IAQ), comfort, and ventilation parameters of each building operating under routine conditions. The objective of the study was to determine the impact of the humidity pump on (1) indoor pollution concentration levels; (2) comfort parameters as perceived by occupants of and visitors to each building; and (3) building ventilation (energy) parameters. Each objective was attained by testing the null hypothesis (Operation of the humidity pump has no impact.) The null hypothesis was tested on occupant exposure levels. Consequently, it was rejected only if the humidity pump affects potential factors that may alter significantly pollutant concentrations, comfort levels, and ventilation rates. Operation of the humidity pump affects levels of volatile organic compounds and microbiological conditions. The humidity pump did not affect comfort and ventilation parameters.
