This course will give mechanical and civil engineers and other design and construction professionals an introduction to the design and construction of HVAC systems for industrial buildings. The guidelines in this course are offered to assist designers with little or no experience in plant HVAC system design. The material presented is a starting point. The material is based on the experience of previous designers and accepted industry codes and standards. In many cases, especially minimum ventilation requirements, the material presented is subject to change due to periodic revisions of codes and standards. The information or materials presented in these guidelines are not intended to circumvent the requirements of applicable codes or standards. The HVAC system designer is ultimately responsible for verifying compliance with the requirements of the latest codes and standards. Where codes and standards differ from these guidelines, the more stringent requirement should be applied in the design.

Learning Objectives:

• Learn how the HVAC system must control air temperature, humidity, cleanliness, and air distribution to maintain an acceptable environment for personnel.
• Learn, when equipment protection is the major objective, the air temperature, humidity, cleanliness, and air distribution must be controlled to protect equipment from freezing, corrosion, and high temperatures.
• Learn why, when equipment contains standing water or water in small pipes, the ambient temperature should be maintained above 45 ºF.;
• Learn how to maintain computer room temperature between 72 ºF and 78 ºF, relative humidity between 45 percent and 55 percent, cleanliness above 90 percent, and minimum outdoor air ventilation of 15 cfm per person.
• Learn how to maintain control rooms temperature between 68 ºF and 80 ºF, relative humidity between 40 percent and 80 percent, cleanliness above 90 percent and minimum outdoor air ventilation of 15 cfm per person;
• Learn about recommended clearances between the equipment and walls, and in front of electric power and control panel doors, and
• Learn recommended configurations for louvers and screens.
