HVAC ) design in discussions of fluid mechanics , thermodynamics, heat transfer, and psychrometrics. Numerous classroom and design office experiences remind us of the value of continuous awareness of the physics of HVAC processes in the conduct of design work.
A dedicated HVAC system is recommended to deal with the range of loads and scheduling issues.
If a wood floor is provided in the gymnasium, humidity control must be reviewed carefully with the flooring manufacturer to ensure the HVAC design will protect the floor. Administrative areas are generally occupied before, during, and after school hours. GTAC Air Conditioning ( Basic Theory ) Introduction to Air Conditioning (GTAC1-1) A basic introduction assuming no previous knowledge of the subject matter. Explains HVAC terminology and basic concepts.
The Instructor package includes PowerPoint presentation, narrated self-study with animations, and testing. The purpose of a duct system is to transmit air from the central air source to the air diffusers located in the building control zones. Figure below shows a central heating furnace connected to supply and return air ductwork.
The furnace is connected to the air plenum at the starting point.
The purpose of this manual is to provide the design engineer with a variety of HVAC solutions for classroom environments. General Issues In North America, the typical school system consists of elementary schools. HVAC systems, like all systems in the building, do not function in isolation, but are part of an interactive system of components. Before addressing the design of the HVAC system , this chapter addresses several aspects of building design that influence the loads imposed on the HVAC system.
Refer to American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Handbook , HVAC Systems and Applications, for guidance on design of these systems. Sum the transmission loads with infiltration and ventilation loads to get the total heating load. Free 2-Day Shipping with Amazon Prime.
Low Prices on Millions of Books. Formerly titled Handbook of HVAC Design , the new edition of this well-known reference offers HVAC engineers, designers, and technicians full coverage of all important aspects of the design , operation, and maintenance of heating , ventilating, and air conditioning ( HVAC ) systems. HVAC – Heating, Ventilation, Air-conditioning.
F (20°C) and 75°F (25°C). A slightly positive pressure to reduce outside air infiltration. Rooms typically have several complete air changes per hour. Low-velocity ductwork design is very important for energy efficiency in air distribution systems.
HVAC design – combining comfort with efficiency When defining an HVAC installation,comfort is the most obvious primary consideration,as it is inva- riably the main reason for installing an HVAC system in the first place. In design of heating system one can use either a system with constant flow and to regulate the heating power by temperature regulation or it can be done by using a variable flow system. This chapter gives the basic knowledge for those systems and to look at general theory of water based heating systems.
