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 can be used for household, commercial, or industrial applications.
DOAS Diagram. Moisture Removal Efficiency (MRE) is a measure of the energy efficiency of any dehumidification process. Moisture removal efficiency is the water vapor removed from air at a defined inlet air temperature and humidity, divided by the total energy consumed by the dehumidification equipment during the same time period, including all fan and pump energy needed to move air and fluids ...
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
Ventilation: 2; Insulation leakage: 1 (a few windows) Cubic meters: 125 m 3 (50 m 2 * 2.5 m height) Density of air: Typically 1.2 for dry air. Humidity Current relative humidity: 20%; Humidity needed to reach 55%: 35% Humidity ratio for 35%: 0.0051
An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning system. [1] An air handler is usually a large metal box containing a blower , furnace or A/C elements, filter racks or chambers, sound attenuators , and dampers . [ 2 ]
An air quality monitor. Human exposure to aerosols has a variety of adverse health effects. [7] Building occupants complain of symptoms such as sensory irritation of the eyes, nose, or throat; neurotoxic or general health problems; skin irritation; nonspecific hypersensitivity reactions; infectious diseases; [8] and odor and taste sensations.

In the anhydrous solid, the metasilicate anion is actually polymeric, consisting of corner-shared {SiO 4} tetrahedra, and not a discrete SiO 3 2− ion. [ 4 ] In addition to the anhydrous form, there are hydrates with the formula Na 2 SiO 3 · n H 2 O (where n = 5, 6, 8, 9), which contain the discrete, approximately tetrahedral anion SiO 2 (OH ...
Boundary value problems are similar to initial value problems.A boundary value problem has conditions specified at the extremes ("boundaries") of the independent variable in the equation whereas an initial value problem has all of the conditions specified at the same value of the independent variable (and that value is at the lower boundary of the domain, thus the term "initial" value).
