Sentences with phrase «emissivity rating»

With generic carbon blend heaters, you'll get an emissivity rating that's significantly lower than Solocarbon heaters, making ours the most effective far infrared heater on the market.

The most important element in an infrared sauna is the heater emissivity rating, which determines how efficiently the infrared heat is emitted.

In technical terms, they have a lower emissivity rating as compared to ceramic heaters.

Ceramic has a very high emissivity rating, meaning it produces a lot of infrared heat.

Not exact matches

If the atmosphere were then optically thin and had a low emissivity (which I would think is likely unrealistic) then it would have an adiabatic - like lapse rate, but the atmospheric temperature would drop from a surface temperature of 255 K, to even lower temperatures.

The atmosphere is really part of the active cooling system of the planet, and increasing CO2 increases the rate of cooling because the sun - heated atmosphere is hotter than the bulk of space and the higher emissivity of the CO2 helps cool the atmosphere.

Or do you think the low emissivity object will cool at the same rate because «but how can it avoid radiating in IR if that is its temperature?»

For those values of emissivities, the atmosphere warms at an even faster rate — about 1.63 times.

This equation assumes that the atmosphere has no convection, has no variation in emissivity with wavelength, has no solar absorption in the atmosphere, and where the heating rate at each level in the atmosphere = zero.
