Full Description

The central thrust of this paper is to introduce the concept of a balanced flow Dedicated Outdoor Air System (DOAS) integrated, physically and functionally, with a pressurization unit. The incentives for this concept include: improved total energy recovery (TER) equipment efficiency, lower first cost, no increase in the installation cost, reduced fan parasitic energy use, predictable building pressurization performance, and a very modest additional first cost for reserve capacity. This may be the next step in the migration path toward improved performance at reduced first cost for DOASs.
