Air Conditioning Calculations Example A building, feet wide and feet long, is constructed with the type of concrete wall indicated in Figure 1. The concrete is inches thick and the polystyrene insulation is inches thick on each side. The east and west walls each have two windows. Low-velocity ductwork design is very important for energy efficiency in air distribution systems.

Low-velocity design will lead to larger duct sizes, but it may be worth since, doubling of duct diameter will reduce friction loss by a factor of times and will be less noisy. Simplistic Design Approach.

Put your presentation title or confidentiality info. Ducts that are not well designed result in discomfort, high energy costs, bad air quality, and increased noise levels. This is both a building system designed to keep the environment comfortable for building occupants and the industry that supports these systems. 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. Administrative areas are generally occupied before, during, and after school. No separate visual aids will be accepted (PowerPoint, , etc).

HVAC Systems: Overview Michael J. Larsen Angel The McGraw-Hill Companies. Trane Trace 7(or the most recent version of Trane Trace). The Trane Air Conditioning Clinic series is one means of knowledge sharing. We have taken special care to make the clinic as uncommercial and straightforward as possible.

DUCT DESIGN, LEVEL 1: FUNDAMENTALS Distribution Systems Space Availability The sizing criteria will often be defined by the space available to run the ductwork (Figure 1). The design parameters used for these calculations are given in ECCCNYS Chapter 3. Easy understanding of air conditioning systems. Ebook, Handbook, Textbook, User Guide PDF files on the internet quickly and easily.

It is for the guidance of mechanical engineers and others in the design and renovation of facilities for Eastern Michigan University (EMU). Use this for learning on the go, but make sure to return to the online course and watch the video before completing any assignments. Heating typically accounts for about half of the energy used in offices.

The general guidelines state that if the winter design temperature for the location of the structure is above 35°F, then both perimeter floor and ceiling distribu-tion systems will provide satisfactory. If the winter design temperature for the location. Chapter Heating, Ventilation, and Air Conditioning 1Figure 7-Air Conditioning with the Vapor Compression Cycle The exterior, air-cooled condensing unit should be kept free from plants and debris that might block the flow of air through the coil or damage the thin fins of the coil.

Ideally, locate the condensing unit in the shade.
