Hoyt Clarke Hottel (1903 – 18 August 1998) was a professor in the department of Chemical Engineering at the Massachusetts Institute of Technology (MIT). He was an expert on energy, radiant heat transfer, fire, fuels and combustion.
When metals were scarce during World War II, Andersen began producing windows using parts less metal and other material to support the war effort. Andersen Corporation also made wooden ammunition boxes for the war effort, which resulted in "Excellence in Production" ("E") awards from the United States Army , and United States Navy .
Operative temperature is used in heat transfer and thermal comfort analysis in transportation and buildings. [10] Most psychrometric charts used in HVAC design only show the dry bulb temperature on the x-axis(abscissa), however, it is the operative temperature which is specified on the x-axis of the psychrometric chart illustrated in ANSI/ASHRAE Standard 55 – Thermal Environmental Conditions ...
Radiant heating as a technology is more narrowly defined. It is the method of intentionally using the principles of radiant heat to transfer radiant energy from an emitting heat source to an object. Designs with radiant heating are seen as replacements for conventional convection heating as well as a way of supplying confined outdoor heating.
Window insulation reduces heat transfer from one side of a window to the other. The U-value is used to refer to the amount of heat that can pass through a window, called thermal transmittance, with a lower score being better. [1] The U-factor of a window can often be found on the rating label of the window.
Ahead, you’ll find expert-recommended materials and practical, cost-effective solutions to fixing drafty windows and reducing heat loss. These tips will help create an energy-efficient, cozy ...
A radiant barrier reflects heat radiation (radiant heat), preventing transfer from one side of the barrier to another due to a reflective, low emittance surface. In building applications, this surface is typically a very thin, mirror-like aluminum foil. The foil may be coated for resistance to the elements or for abrasion resistance.
This Midea window air conditioner is the perfect size for a bedroom, kitchen or even a smaller living room. Normally $175, it's now marked down on Walmart to just $144, making it quite the steal ...
