Excess humidity Cheap Dan Hamhuis Hat , odors, and contaminants can often be controlled via dilution or replacement with outside air. However, in humid climates much energy is required to remove excess moisture from ventilation air.
Ventilating is the process of changing or replacing air in any space to control temperature or remove moisture, odors, smoke, heat Cheap Tyler Seguin Hat , dust and airborne bacteria. Ventilation includes both the exchange of air to the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings. Methods for ventilating a building may be divided into mechanicalforced and natural types. Ventilation is used to remove unpleasant smells and excessive moisture, introduce outside air, and to keep interior building air circulating, to prevent stagnation of the interior air.
Canada Fan Co. offer quite a few techniques of efficient building ventilation and cooling. In industrial plants where there is a high density of employees and many manual operations involved, an improvement in the environment can produce substantial benefits in terms of increased production, reduced errors Cheap Jamie Benn Hat , and a decline in complaints and absenteeism among employees. In other circumstances, the attentiveness of an audience or student group may be a factor that spells success or failure for the project.
To obtain a reasonable degree of personnel comfort in hot weather, there are three basic factors that should be provided for in the ventilation and coolong system of a commercial or industrial building.
Forced ventilation is used to control indoor air quality. Excess humidity, odors, and contaminants can often be controlled via dilution or replacement with outside air. However, in humid climates much energy is required to remove excess moisture from ventilation air.
Kitchens and bathrooms typically have mechanical exhaust to control odors and sometimes humidity. Factors in the design of such systems include the flow rate (which is a function of the fan speed and exhaust vent size) and noise level. If the ducting for the fans traverse unheated space (e.g. Cheap Jason Spezza Hoodie , an attic), the ducting should be insulated as well to prevent condensation on the ducting. Direct drive fans are available for many applications, and can reduce maintenance needs.
Ceiling fans and table floor fans circulate air within a room for the purpose of reducing the perceived temperature because of evaporation of perspiration on the skin of the occupants. Because hot air rises, ceiling fans may be used to keep a room warmer in the winter by circulating the warm stratified air from the ceiling to the floor. Ceiling fans do not provide ventilation as defined as the introduction of outside air.
Another ype of venting - natural ventilation is the ventilation of a building with outside air without the use of a fan or other mechanical system. It can be achieved with operable windows or trickle vents when the spaces to ventilate are small and the architecture permits. In more complex systems warm air in the building can be allowed to rise and flow out upper openings to the outside (stack effect) thus forcing cool outside air to be drawn into the building naturally through openings in the lower areas. These systems use very little energy but care must be taken to ensure the occupants' comfort. In warm or humid months, in many climates, maintaining thermal comfort via solely natural ventilation may not be possible so conventional air conditioning systems are used as backups. Air-side economizers perform the same function as natural ventilation Cheap Alexander Radulov Hoodie , but use mechanical systems' fans, ducts, dampers, and control systems to introduce and distribute cool outdoor air when appropriate.

A video of police officer Liang Tao singing to help calm down a mentally ill woman has gone viral online, the Chongqing Morning News reported on Wednesday.
Liang, 32 Cheap Ben Bishop Hoodie , sang for two hours to a woman in a police station in Southwest China's Chongqing municipality. The woman was so pleased with the singing that, while clapping her hands, she asked Liang, "Are you a singing god?"
The video went viral online with over 700,000 clicks within 3 hours.
Liang found the woman lingering in the countryside in Chongqing on May 9. She failed to clearly give her home address, and wasn't carrying correct ID. She repeatedly said her last name was "Ka". Liang took her back to the police station for her own safety Cheap Stephen Johns Hoodie , and when she appeared nervous, he began to sing to her.
Liang was able to contact the woman's husband, Mr Ma, who confirmed that the woman, surnamed Wang, was mentally ill and arranged for her to be collected from the police station.
A grateful Ma said that Wang had become lost while he was busy outside Cheap Brett Ritchie Hoodie , which has happened several times before. Wang likes songs, especially happy ones, he said.
