Design Guide for Heating, Ventilating, and Air Conditioning Systems

File Size: 28.40 mb

Description

SCOPE.—This guide assumes that prospective users will have some heating, ventilating, and air conditioning (HVAC) design experience but are not familiar with the specific requirements for the Bureau of Reclamation (Reclamation) facilities. The guide emphasizes design considerations and
recommendations for applications specific to powerplants, pumping plants, and confined spaces such as tunnels, gate chambers, and valve vaults. The guide also identifies recognized codes and standards that should be referred to as necessary when designing HVAC systems for Reclamation facilities.

Most HVAC system designers should be familiar with the design requirements for office buildings. Except for recommended ambient conditions, office HVAC systems are not included in this guide.

Heating and cooling load calculations and procedures for Reclamation facilities are essentially similar to those for most structures familiar to the HVAC designer and are not addressed in this guide. The calculations and procedures are readily available in many of the references noted throughout
the guide and listed in the appendix.

Throughout this guide, the term “Plant” applies equally to powerplants and pumping plants and the term “Units” refers equally to the main generating units, pump/generating units, or pump units unless otherwise stated.
