Problem Set
One of the advantages of a window assembly that uses an inert gas in the air gap is: (a)Inert gases are not explosive. (b)The inert gas acts as an insulator and reduces the heat transfer through the window. (c)These windows can use single pane glazing. (d)Windows with inert gases are low cost.
Teaching Material
For air conditioners and heat pumps, we size the wires and circuit breakers in accordance with the information printed on the label, not the simplified sizing charts that we typically rely on.
Teaching Material
In this guide, you will learn how to choose the most suitable type of heat pump system according to the specific requirements of your project.
Problem Set
Core systems A. Use a central plumbing core, where plumbing areas are placed in close proximity to the water heater. B. Pipe hot water directly to each fixture or group of fixtures using smaller diameter piping when appropriate and as direct a path as possible. C. Are more expensive and take longer...
Problem Set
Demand-Initiated Recirculation Systems A. Consist of one continuous hot water supply loop that recirculates water throughout the home. B. Save water because they can reduce the wait time for hot water and return ambient-temperature water stored in the piping back to the heater. C. Are considered...
Problem Set
Manifold Plumbing Systems A. Uses larger, inflexible piping. B. Are also called parallel pipe or home run systems C. Use small diameter, flexible piping (such as PEX) that run directly to each individual fixture from a central manifold. D. Use of flexible piping allows these systems to be installed...
Problem Set
Trunk and branch systems A. Are the most common type of hot water delivery system. B. Are most suitable for larger homes in terms of maximizing hot water delivery system efficiency. C. Are characterized by one long, large diameter main line (i.e., the “trunk”) that runs from the water heater to the...
