A humidifier is a household appliance or device designed to increase the moisture level in the air within a room or an enclosed space. It achieves this by emitting water droplets or steam into the surrounding air, thereby raising the humidity.
Diagram showing airflow through a heat-recovering dehumidifier. Warm, moist air is drawn into the unit at A in the diagram above. This air passes into a crossflow plate heat exchanger (B) where a substantial proportion of the sensible heat is transferred to a cool supply air stream. This process brings the extracted air close to saturation.
In humidifiers and dehumidifiers, the humidistat is used where constant relative humidity conditions need to be maintained such as a refrigerator, greenhouse, or climate-controlled warehouse. [2] When adjusting the controls in these applications the humidistat would be what is being set.
The Kawasaki OH-1 (nickname: "Ninja") is a military scout/observation helicopter developed and manufactured by the Kawasaki Aerospace Company.The primary operator is the Japan Ground Self-Defense Force (JGSDF), who originally procured the OH-1 as a domestically produced successor to their existing OH-6D Loach fleet.
Potassium osmate is the inorganic compound with the formula K 2 [OsO 2 (OH) 4]. This diamagnetic purple salt contains osmium in the VI (6+) oxidation state. [1] When dissolved in water a red solution is formed. When dissolved in ethanol, the salt gives a pink solution, and it gives a blue solution when dissolved in methanol. [1]
Electronic humidifiers are also available, although usually reserved for very large humidors. [citation needed] A sensor measures the outside humidity and then activates a ventilator, which blows air over a humid sponge or water tank into the humidor. Once the preset humidity level has been reached the ventilator stops.
On November 11, 2011, six humidifier disinfectants which contain PHMG and PGH were recovered. PHMG and PGH was banned in 2011, and new cases ceased occurring. [ 1 ] [ 2 ] However, later on, the Korea Centers for Disease Control and Prevention did not find a causal relationship that CMIT and MIT in humidifier disinfectants cause pulmonary fibrosis .
Holmes Products was founded by Jordan Kahn in 1982. [1] [2] In 2005, Berkshire Partners, Holmes' parent company, sold Holmes Products to Jarden Corporation for US$625.9 million.
