The desiccant absorbs moisture from the air leaving the cold surface, releasing heat and drying the air, which can be used in a process requiring dry air. The desiccant is then dried by an air stream at a lower relative humidity, where the desiccant gives up its moisture by evaporation, increasing the air's relative humidity and cooling it ...
This buildup prevents the dehumidifier from operating effectively, and can cause water damage if condensed water drips off the accumulated ice and not into the collection tray. In extreme cases, the ice can deform or distort mechanical elements, causing permanent damage. Better-quality dehumidifiers may have a frost or ice sensor.
It was developed in 1999 by Charles Cressy as an alternative to conventional refrigerant and desiccant dehumidifier drying techniques. In July 2013 British Standards PAS 64 "Mitigation and recovery of water damaged buildings - Code of practice" was published recognising and including descriptions of the process within the document.
A desiccant wheel is very similar to a thermal wheel, but with a coating applied for the sole purpose of dehumidifying, or "drying", the air stream. The desiccant is normally silica gel . As the wheel turns, the desiccant passes alternately through the incoming air, where the moisture is adsorbed , and through a “regenerating” zone, where ...
L. M. Kachanov [5] and Y. N. Rabotnov [6] suggested the following evolution equations for the creep strain ε and a lumped damage state variable ω: ˙ = ˙ ˙ = ˙ where ˙ is the creep strain rate, ˙ is the creep-rate multiplier, is the applied stress, is the creep stress exponent of the material of interest, ˙ is the rate of damage accumulation, ˙ is the damage-rate multiplier, and is ...
The claim: Donald Trump can't travel to Canada because he is a convicted felon. A Dec. 3 Threads post (direct link, archive link) offers a theory as to why Canadian Prime Minister Justin Trudeau ...
One measure of desiccant efficiency is the ratio (or percentage) of water storable in the desiccant relative to the mass of desiccant. Another measure is the residual relative humidity of the air or other fluid being dried. For drying gases, a desiccant's performance can be precisely described by the dew point of the dried product.

Water expands when it freezes, Sperlich said, so people should drip indoor facets when temps dip below 32 degrees. Just make sure you drip the farthest faucet from your main valve. "You don't have ...
