Editing 2753: Air Handler

[[Black Hat]] is demonstrating an 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.

In many devices that manage certain atmospheric conditions in a building using one device, an operational range is usually defined, and not one number.  For example, when using a {{w|heat pump}}, if the interior temperature drops below a preset lower limit, then the heating function would be activated.  If the interior temperature rises above another preset upper limit, the cooling function would be activated. This kind of ranged function is common with humidifier/dehumidifier units as well, to create a comfortable condition not too dry nor too damp for comfort.  By specifying upper and lower limits for the operation of the device in question, minor variations of the controlled value will not cause the device to rapidly turn on and off, even working against itself, improving efficiency and reducing unnecessary wear and tear on the device and the building contents.

Changing the pressure of the air could lead to <s>unintended</s> effects like large winds blowing through any cracks in the building.

The air handler also attempts to force the parameters of dust, smoke, odours, and number of bees into an "ideal" range. However, as opposed to being in a certain range, most people who live indoors prefer that these be minimised.{{fact}} It's also worth noting that "a normal amount" of bees varies widely depending on the situation. A typical honeybee colony contains [https://www.science.org.au/curious/earth-environment/honeybee-hive 60,000 to 80,000 bees], and a typical {{w|Swarming_(honey_bee)|swarm}} (bees looking to establish a new hive) is anywhere from [https://www.bee-commerce.com/content/freedownloads/FactsAboutSwarms.pdf 1,500 to 30,000]. To pollinate an acre of fruiting trees typically requires a minimum of [https://treefruit.wsu.edu/orchard-management/pollination/honey-bees/ 20,000 bees], or approximately five bees per square meter.

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 agriculture) to have a non-zero ''minimum'' desirable quantity of bees. Even more so to then be directly equipped to upwardly correct the current value. For any minimum value that is not zero, this machine would be equipped to deal with it by, presumably, releasing bees (it seems to have at least one trapped inside it ready to be released, judging by the buzzing sound), or by generating smoke, dust and odours – something one would typically not miss if lacking.{{citation needed}}

 

As the title text elaborates, the machine analyses and adjusts the ''freshness'' of the air. A smart system in charge of odour-control (by spraying smell-suppressing chemicals and/or more desirable and 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 with dirty laundry.
