Air conditioning apparatus having audible sound level control function

The relationship between olfactory perception threshold and accompanying degrees of nasal obstruction, swelling, color and wetness was studied in eight subjects over a prolonged period. Olfactory acuity was impaired in two situations: a) in the presence of high degrees of nasal obstruction so that relatively little of the odorant-containing air could be brought into the nose, and b) in the absence of obstruction when the mucosa was relatively pale, dry and shrunken. During intermediate degrees of nasal obstruction when substantial amounts of air could be drawn into the nose relatively high degrees of swelling, redness and wetness favored olfactory acuity. Thus smelling was best performed in the presence of a red, swollen, wet mucosa as long as swelling and secretions were not of such a degree as to substantially block air passage. The evidence suggests that contact of odorant with nerve endings is facilitated by the greater warmth and humidifying effect of nasal engorgement during hyperfunction of the ‘air-conditioning’ apparatus of the nose.

And Control

The operation control of the micro-grid system is the foundation to protect micro-grid equipment, to realize associate control and optimize economic operation. Looking on Chenjiazhen micro-grid in Shanghai as model, the paper set three hierarchical controls: protection control, micro-grid coordinated controller control which can achieve millisecond time precision and intelligent community energy management system control. Different level control function has been divided. Control functions in all levels complement each other and collaborate together to achieve the coordination and control of micro-grid running.
