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 .
Free cooling. Free cooling is an economical method of using low external air temperatures to assist in chilling water, which can then be used for industrial processes, or air conditioning systems. The chilled water can either be used immediately or be stored for the short- or long-term. When outdoor temperatures are lower relative to indoor ...
Radiant heating and cooling. Radiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels", [1] "embedded surface systems", [1] "thermally ...
At a lower limit, clear sky (cloud-free) conditions promote the largest opening of transmission windows. The more uniform concentration of long-lived trace greenhouse gases in combination with water vapor pressures of 0.25-20 mbar then yield minimum values in the range of ε a =0.55-0.8 (with ε=0.35-0.75 for a simulated water-vapor-only ...
Near doors or windows, where sunlight and ambient heat may create a falsely high reading. Don’t worry about running a ceiling fan in the same room as the thermostat. Fans cool people, not air ...
Computer cooling. A finned air-cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background. A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components. Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.
Thermal mass. In building design, thermal mass is a property of the mass of a building that enables it to store heat and provide inertia against temperature fluctuations. It is sometimes known as the thermal flywheel effect. [1] The thermal mass of heavy structural elements can be designed to work alongside a construction's lighter thermal ...
The Metro Action Commission is hoping to help. Through the Summer Cooling Program, eligible residents can receive a free fan or air conditioning unit and, in some circumstances, both, between now ...
