Sentences with phrase «whereas water heating»

Apparently the efficiency of PV drops dramatically with a little shade, whereas water heating maintains close to optimal efficiency, even when partially shaded.

Not exact matches

I can't help but notice that the St. Vincents Gulf temperature now is 22 C, including something like a 3 C positive anomaly, whereas the normal winter air temperature in Adelaide may be something like 12 C. Using «cooling tower» calculations, I think it should be possible to heat up the air by contacting it with 22 C sea water raining through it to a temperature of at least 18 C.

``... whereas the thermal lag of water by contrast is great and whilst energy is being absorbed due to its large heat capacity the response is slow...»

A thin sheet of metal quickly absorbs the solar energy, and having good conductivity, quickly converting it into an increase in heat whereas the thermal lag of water by contrast is great and whilst energy is being absorbed due to its large heat capacity the response is slow.

The identified atmospheric feedbacks including changes in planetary albedo, in water vapour distribution and in meridional latent heat transport are all poorly represented in zonal energy balance model as the one used in [7] whereas they appear to be of primary importance when focusing on ancient greenhouse climates.

Electric oven provide dry heat whereas gas ovens supply heat and gases water.

So whereas the experiment at home with a pot of water on low heat yields a time lag of something like 10's of minutes to heat the water, to heat an Earth - sized pot of water the time lag is about 30 years.

According to Cool Power COO Richard Linger, a 10 - kilowatt - capacity battery storage system would cost $ 7000 (plus installation) and require replacement in 7 years to 9 years, whereas an EMMA would capture and store 10 kilowatts for heating or hot water, cost $ 1500, have lower installation costs and last 15 to 20 years.

Whereas the condensation of water vapor liberates heat and whereas that phase change does not exhibit a temperature change therefore, black bodies from outer space are not telling much about the planet's energWhereas the condensation of water vapor liberates heat and whereas that phase change does not exhibit a temperature change therefore, black bodies from outer space are not telling much about the planet's energwhereas that phase change does not exhibit a temperature change therefore, black bodies from outer space are not telling much about the planet's energy flux.

In these cases, the prevailing dry conditions set the stage for the heat since the land is dried out, the vegetation is wilted, and all of the heat from the sun goes into raising temperatures, whereas ordinarily, in the process of evaporative cooling, surface water or wetness acts as an evaporative cooler (swamp cooler) of sorts.

• Conductivity levels in different surfaces vary, so think about how they feel to the touch — cold steel and cast iron absorb heat and cool water quickly, whereas composites like Corian, Cristalplant and LG Hi - Macs retain heat for longer.
