Distribution Effectiveness and Impacts on Equipment Sizing for Residential Thermal Distribution Systems

摘要

This report builds on and extends the authors' previous efforts described in 'Leakage Diagnostics, Sealant Longevity, Sizing and Technology Transfer in Residential Thermal Distribution Systems--CIEE Residential Thermal Distribution Systems Phase VI Final Report, December 1998' (DE00008681). This report concentrates on a new area of work: the interaction between distribution system effectiveness and equipment sizing. This issue focuses on the ability of downsized equipment with a good distribution system to deliver the same cooling to conditioned space as a typical Heating, Ventilating and Air Conditioning (HVAC) system. The cooling of the conditions space is evaluated by looking at the concept introduced in the previous phase of this study: 'Tons At the Register' together with comfort issues, such as how quickly a house is cooled ('pulldown time'), and the distribution of cooling throughout the house.
