Guide Overview
The HVAC Engineering Book’s guide systemizes the ASHRAE calculation methods and standards into an "HVAC design technology".
The guide contents reflect all of the design stages from the development of the system design concept to the preparation of the HVAC drawings.
The main guide features include the following:
- Thermal comfort in the spaces with radiant heating panels or other special indoor conditions is predicted using the methodology of Standard 54-2004 "Thermal Environmental Conditions for Human Occupancy"
- The space- and system-level ventilation air volume requirements are calculated based on Standard 62.1-2007 "Ventilation for Acceptable Indoor Air Quality"
- Conduction and Radiant Time Series methods replace the obsolete Transfer Function method to calculate the space cooling loads
- The guide checks compliance of the HVAC system design with the Standard 90.1-2007 "Energy Standard for Buildings Except Low-Rise Residential Buildings"
- The calculated primary, secondary, and tertiary cooling and heating equipment capacities are checked against the building load breakdowns
- To determine capacities of the central cooling coil, preheat coil, and humidifier, the guide calculates the moist air properties before and after each element of the air-handling unit based on: the summer and winter design outdoor and indoor air conditions; the air-handler configuration; and the system controls strategy
- Tutorials at the end of each chapter demonstrate application of the described calculation methods
- To illustrate the described methods, the guide instructs the reader on how to design a constant air volume system for a public building. The design progress is demonstrated by a set of drawings
- The guide provides a set of reference tables adopted and reformatted from relevant ASHRAE handbooks and standards, sufficient for learning the HVAC design process without a need to purchase additional literature
- Practicing engineers can use the guide as a reference for the computations coded in the Excel modules
- The guide contains over 240 pages including drawings, schematics, diagrams, and pictures.
