Editing 2753: Air Handler

The device being demonstrated appears to be some form of air-conditioning unit that covers a wide-variety of air qualities, as opposed to a heater that just warms air, a filter that just removes dust or a dehumidifier with the main purpose of removing moisture from the air.

If such a unit contains both heating and refrigeration elements to it, it would be neither practical nor desirable to have a single temperature reference, below which the heating is triggered and above which the cooling is activated, as the sharp transition between the two could trigger a rapid switch backwards and forward between the two modes after any gross difference has been ameliorated and the instantaneous amount of difference from the ideal is much smaller (in either direction) than the change that a burst of alternating effects can propogate into the room. Instead, a lower limit and an upper limit can prompt each respective correction, with a range of degrees between which is deemed acceptable, though the measurement may drift a bit as doors are opened, people enter the room or just that convection finally sends volumes of previously severely heated or cooled air past the sensor. The engineering choices involved in making a usable device may be pre-set or left user-configurable. The same principle can be applied to humidifier/dehumidifier functions, to create a comfortable condition not too dry nor damp for comfort, etc.

It is not particularly usual to directly monitor the number of bees in an air-stream (usually, insect-screens are the main way to filter out any pesky creatures that might find themselves likely to be caught up in that way), and one might imagine that the upper limit ''should'' be zero, for use indoors in standard living/working spaces, but it might be technically feasible to accurately count bees (with or without distinguishing from wasps and other flying insects) and be able to allow ''some''. But, unlike temperature or humidity, it would be rare (outside of a location used for apicultire) to have a non-zero ''minimum'' desirable bee-load. Even more so to be directly equipped to upwardsly correct the current value.

The title text adds to the more visibly obvious bee-quantifying into a 'normal' range, and describes how it analyses and adjusts the 'freshness' of the air. A smart system in charge of odour-control (by spraying smell-suppressing chemicals and/or more dominant scents) could be made less wasteful by only trying to 'freshen' the air when it detects enough necessity. But, of course, this machine also has an opposing limit. And, when the air is considered ''too'' fresh, it has a way of ''adding'' staleness/stinkiness, to meet expectations.

:Megan: What's the '''''lower''''' limit for "Number of bees"?
