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.
A properly installed and located hygrostat should be used to monitor and control humidity levels automatically, or a well-informed and conscientious human operator must constantly check for correct humidity levels. A humidity below 50% can prevent water condensation on building materials. [1] A dehumidifier can be used to balance the humidity.
An Air Force report states: Each individual nap should be long enough to provide at least 45 continuous minutes of sleep, although longer naps (2 hours) are better. In general, the shorter each individual nap is, the more frequent the naps should be (the objective remains to acquire a daily total of 8 hours of sleep). [27]
Indoor relative humidities should be kept above 30% to reduce the likelihood of the occupant's nasal passages drying out, especially in winter. [40] [43] [44] Air conditioning reduces discomfort by reducing not just temperature but humidity as well. Heating cold outdoor air can decrease relative humidity levels indoors to below 30%. [45]
This numbered air force was established as Fifth Air Force, Advance, and organized at Itazuki AB, Japan, assigned to Fifth Air Force, on 14 July 1950. It moved to Taegu AB, South Korea, on 24 July 1950, and was redesignated Fifth Air Force in Korea at the same time. After moving, it apparently received command control from U.S. Far East Air Forces.

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 ...
A true deodorant — one that's simply meant to block odor and does not prevent sweating — isn’t necessary to wear to bed, since people sweat less at night, especially with air conditioning ...
