A typical "portable" dehumidifier can be moved about on built-in casters. A dehumidifier is an air conditioning device which reduces and maintains the level of humidity in the air. [1] This is done usually for health or thermal comfort reasons or to eliminate musty odor and to prevent the growth of mildew by extracting water from the air. It ...
The pump then runs until the level of liquid in the tank is substantially lowered. Some pumps contain a two-stage switch. As liquid rises to the trigger point of the first stage, the pump is activated. If the liquid continues to rise (perhaps because the pump has failed or its discharge is blocked), the second stage will be triggered.
A French drain, PVC pipe, or other drainage system is installed in the newly made channel. The installed drain is covered with new cement. The drainage system collects any water entering the basement and drains it to an internally placed sump pump system, which will then pump the water out of
Cooling coils will also employ eliminator plates to remove and drain condensate. The hot water or steam is provided by a central boiler , and the chilled water is provided by a central chiller . Downstream temperature sensors are typically used to monitor and control "off coil" temperatures, in conjunction with an appropriate motorized control ...
The chamber is maintained at a pressure that is lower than the water supply pressure, but high enough to be useful downstream. The reduced pressure is guaranteed by a differential pressure relief valve, which automatically relieves excess pressure in the chamber by discharging to a drain.
The trench would then be back-filled with a porous material such as a single-sized aggregate, forming a French drain. Such a system would obviously have the practical disadvantage of being suitable only for the treatment of outside walls and would be impractical where other buildings are close by or where a building has shallow footings.
An Egyptian qullah, set in drafts to cool interiors. Porous pottery and coarse cloth maximize the area for evaporation. An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water.
Take-offs may be fitted into round or rectangular openings cut into the wall of the main duct. The take-off commonly has many small metal tabs that are then bent to attach the take-off to the main duct. Round versions are called spin-in fittings. Other take-off designs use a snap-in attachment method, sometimes coupled with an adhesive foam ...
