Field Measurements of Efficiency and Duct Retrofit Effectiveness in Residential Forced Air Distribution Systems
نویسندگان
چکیده
Forced air distribution systems can have a significant impact on the energy consumed in residences. It is common practice in U.S. residential buildings to place such duct systems outside the conditioned space. This results in the loss of energy by leakage and conduction to the surroundings. In order to estimate the magnitudes of these losses, 24 houses in the Sacramento, California, area were tested before and after duct retrofitting. The systems in these houses included conventional air conditioning, gas furnaces, electric furnaces and heat pumps. The retrofits consisted of sealing and insulating the duct systems.

Airtightness, Ventilation, and Energy Consumption in a Manufactured House: Pre-Retrofit Results
A retrofit study is being conducted to investigate the airtightness, ventilation and energy impacts of tightening the exterior envelope and the heating and air conditioning system ductwork of a double section manufactured house. This report describes the results of the pre-retrofit assessment of building airtightness, ventilation, and energy consumption under both heating and cooling conditions...
متن کاملEnergy Implications of Filtration in Residential and Light-Commercial Buildings
Higher-efficiency HVAC filters generally have a higher pressure drop and are widely assumed to increase energy consumption in smaller air conditioning systems. To explore the effects of filters in real buildings, we monitored 17 residential and light-commercial forced air cooling systems in Austin, TX. Measurements were made once per month for one year at each site with filters from three diffe...

It has been determined from extensive testing conducted between May 1987 and May 1988, in the hot and humid climate of central Florida, that pressure differences within the envelope of residential housing exists. These can range from near neutral to pressures, either positive or negative, as great as 0.24" W.C. (60 pascals). Reasons sighted and discussed in this paper include duct system design...

The purpose of ventilation is dilute or remove indoor contaminants that an occupant is exposed to. In a multi-zone environment such as a house, there will be different dilution rates and different source strengths in every zone. Most US homes have central HVAC systems, which tend to mix the air thus the indoor conditions between zones. Different types of ventilation systems will provide differe...
