Online Air Volume eLearning

Laboratory Building Energy Analysis Overview Because laboratories use a high amount of energy, often more than five times as much per square foot as an office building, it is important to find cost-effective ways to reduce their energy use and costs. In this course the student will learn about energy efficiency strategies including reducing the air flow during unoccupied periods, variable-air-volume systems, lower static  more...

HVAC Tips for Green Buildings ... air distribution system including air handlers, variable air volume systems, optimal air distribution systems, and ductwork ?The heat recovery devices and systems such as airside & waterside economizers, enthalpy & heat wheels, heat pipe systems and run-around systems ?Alternate system designs using dedicated outdoor air handling systems, demand control ventilation, displacement ventilation,  more...

Laboratories Best Practices Modeling Exhause Dispersion Overview Studies have shown a direct relationship between indoor air quality and the health and productivity of building occupants. Historically, the study and protection of indoor air quality has focused on emission sources emanating from within the building including laboratories. Emissions from external sources, which may be re-ingested into the building through closed circuiting between the  more...

HVAC - Concepts and Fundamentals Overview HVAC helps keep people comfortable and healthy by maintaining good indoor air quality, humidity and comfortable temperatures. Designing for comfort requires integrated knowledge of human physiology, heat transfer, psychrometrics, and mechanical systems. Most professionals don't learn this stuff in school or on the jobsite, but are expected unrealistically to meet your physiological needs  more...

HVAC - Equipment and Systems Overview HVAC system components may be grouped into three functional categories: source components, distribution components, and delivery components. Source components provide or remove heat or moisture. Distribution components convey a heating or cooling medium from a source location to portions of a building that require conditioning. Delivery components serve as an interface between the  more...

Ventilating and Heating of Small Livestock Rooms Modern livestock facilities frequently include one or several small rooms to house the young, more sensitive animals. A small livestock room is hard to ventilate. The small volume of air in the room is very sensitive to changes in ventilation rate, heat supply and drafts due to uncontrolled air distribution. In this course the student will learn some techniques of how to effectively ventilate  more...

VAV System Design ...Air Volume (VAV) systems are a popular type of HVAC system in commercial buildings for both energy savings and comfort; however, there are multiple considerations that must be taken into account during design in order to realize these design objectives and avoid pitfalls. In this course the student will learn some of the basic considerations that should be taken into account when considering  more...

Air Conditioning Systems Most people think the air conditioning system's job is just to add "cold? air to the space. Actually air-conditioning is a process by which air is cooled and dehumidified by mechanical means. In a broader sense, air conditioning includes both the cooling and heating of air, cleaning it and controlling its moisture level, and conditioning it to provide maximum indoor comfort. Engineers define  more...

Kitchen Makeup Air A universal concern regarding the commercial kitchen space is having an effective ventilation system. A large portion of kitchen ventilation planning is dedicated to properly exhausting cooking effluent. Appliance layout and the energy input are evaluated, hoods are located and specified, the ductwork size and routing are determined, and exhaust fans are specified to remove the proper volume of  more...

HVAC - Variable Air Volume Systems ...for delivering air to the conditioned space: constant air volume (CAV) systems, and variable air volume (VAV) systems As the name implies, constant volume systems deliver a constant air volume to the conditioned space irrespective of the load. VAV systems, on the other hand, are designed to simultaneously meet a variety of cooling and heating loads in a relatively efficient manner. The  more...

Cooling Towers The machines and processes of industry, as well as the air-conditioning systems for buildings generate tremendous amounts of heat, which must be continuously dissipated if these machines and processes are to continue to operate efficiently. Water cooling is the most efficient method of dissipating heat. A cooling tower is a device used in industry to cool hot water (by partial evaporation)  more...
