Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. [ 1][ 2] This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building ...
Temperature control. Temperature control is a process in which change of temperature of a space (and objects collectively there within), or of a substance, is measured or otherwise detected, and the passage of heat energy into or out of the space or substance is adjusted to achieve a desired temperature. [1] Thermoregulation is the act of ...
An equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. [1] The unit of measurement for loudness levels is the phon and is arrived at by reference to equal-loudness contours. By definition, two sine waves of differing ...
Don’t use speakerphone. Do not use speakerphone for calls you make in public — use headphones. This is especially true for video calls or when watching to something on your device. This ...
e. Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [1]
Teresa explained, “It was her birthday. I was scrambling. I’m was like, 'Oh, my God. It’s her birthday. I have to post a picture for her.'. You know, we’re really close. And then, I was ...
Create a buffer zone. To separate your sleep area from the rest of the apartment, you could get a freestanding screen, room divider or “floating" (hanging) wall. And as much as you can, keep ...
Radiative cooling. Earth's longwave thermal radiation intensity, from clouds, atmosphere and surface. In the study of heat transfer, radiative cooling [1] [2] is the process by which a body loses heat by thermal radiation. As Planck's law describes, every physical body spontaneously and continuously emits electromagnetic radiation .
