Dehumidification can be key to comfort: optimal humidity levels in schools can help students, teachers.(School IAQ)(indoor air quality)(Heating Ventilation Air Conditioning and Refrigeration )(Column)Hall, John R
Multiple studies have investigated the relationship between SARS-CoV-2 transmission and weather factors, including temperature, humidity, ultraviolet radiation39, suggesting that summer conditions may help in reducing transmission of the virus. Seasonal factors and simultaneous social distancing interventions ar...

Dry seasons, electric heaters and radiators can excessively reduce indoor humidity. You can easily increase the humidity level with a humidifier. Remember to be careful not to humidify the room too much. Relative humidity above 70% creates favourable conditions for mould and bacteria to grow....
A damp basement is hardly a pleasant place to be. There is a high risk of mould forming if the level of humidity down there is permanently too high. This, along with the humidity itself, can attack, cause damage to and even destroy goods in storage, supplies, furniture and walls. Read...
Don’t Let Humidity Create a Breeding Ground Proper temperature control aids in maintaining an appropriate level of humidity. High humidity levels create a breeding ground for bacteria and fungi. This can lead to infections among vulnerable patients. ...
Modern datacenters use HVAC systems to control indoor temperature, humidity, and other variables. It is common to have many HVAC units deployed throughout a data center. They are often floor-standing units, but may be wall-mounted, rack-mounted, or ceiling-mounted. The HVAC units also often ...
(Hg). Vapor pressure is a function of the temperature and relative humidity (RH) of the air to which a test structure is exposed, and may be found in many standard data tables. The vapor pressure at any certain RH is found by the product of the RH and the vapor pressure for ...
As the first effort, two control strategies (i.e., optimal and nearoptimal) are developed to address the environment control issues (concerning both indoor temperature and humidity controls) under a pre-determined power limiting threshold during DR events. The optimal control strategy optimizes the...
The purpose of this paper is to clarify the follwing two points.First point is the indoor air temperature and humidity fluctuationunder an optimal operation of heat source system. Second is theeffect of the system composition (heat source equipment capacityratio)on the optimization results.method ...
