Sentences with phrase «humidity levels within»

As the sensible heat load is reduced for a building, primarily through better windows, more insulation, and air distribution ducts inside conditioned space, the latent load increases in proportion to the total load to the point that conventional cooling systems have difficulty keeping humidity levels within comfortable and healthy limits3.

Not exact matches

When the air indoors reached the desired level of humidity, it saves power by not running while the humidity level is within the desired range.

A TSB - funded post-occupancy evaluation of the Wimbish passive house development for Hastoe Housing found that occupants were happy with air quality, «occupied» CO2 levels were generally around or below 1000 ppm, and humidity was «within normal limits» (although marginally low in some houses at the end of each winter).5

Measurement of CO2 concentration is always problematic; the «Standard Dry Air» SDA basis of measurement and comparison is at standard temperature and pressure which is a non-existent parameter; and as we are seeing, CO2 is not a well - mixed gas at all and will be defined by, amongst other variables, SH, or absolute humidity; SH can vary from 0 to 5 % by volume of atmosphere; as the SH increases, the absolute amount of other gases, including CO2, decreases; to say therefore that atmospheric concentrations of CO2 have remained stable and not been above 280ppm over the last 650my is fanciful; even if you assume past CO2 levels have not got above 280ppm the range of variation within that limit has been greater than the current increase;

Anyway, our paper concluded by suggesting that, in view of the extreme significance of upper - level humidity to the climate change story, the international radiosonde data on upper - level humidity should not be «written off» without a serious attempt at abstracting the best possible humidity signal from within the noise of instrumental and operational changes at each of the relevant radiosonde stations.

Without a provincial air quality standard, there is no way of knowing whether the air within the property has been adequately remediated for such problems as leaky building envelopes, illegal grow - op activities or high levels of continued humidity that produce mould, says CREB.

But if these are the typical dryer found here in the USA, then the moisture is expelled through the exhaust vent; failure to properly vent these to the outside would lead to high moisture / humidity levels in the air within the unit - one of the things that could lead to mold developing.
