2. HVAC control system - Wikipedia

   en.wikipedia.org/wiki/HVAC_control_system

   HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...

   That’s not to say airborne viruses and bacteria — such as those that cause tuberculosis, the common cold, the flu and certain fungal infections — can’t pass through an AC unit in theory.

4. Cromer cycle - Wikipedia

   en.wikipedia.org/wiki/Cromer_cycle

   The air picks up moisture and cools in process 1 to 2. The moist air is now presented to the cooling surface (cooling coil of the air conditioner), which cools it below its dew point and dries the air in process 2 to 3. This represents the work done by the cold coil. In the meantime, the dried desiccant from below is rotated to the upper air ...

5. Freeze stat - Wikipedia

   en.wikipedia.org/wiki/Freeze_stat

   In practical situations, when an air coil freeze stat is not used, bypassed, or defeated, the air coil can freeze, and this causes a lack of air flow to the facility. [3] By contrast, when a water coil freeze stat is not used, the water coil can get so cold that it can freeze the cooling liquid in the exchanger and burst the exchanger. [ 5 ]

6. Deep water source cooling - Wikipedia

   en.wikipedia.org/wiki/Deep_water_source_cooling

   Deep water source cooling (DWSC) or deep water air cooling is a form of air cooling for process and comfort space cooling which uses a large body of naturally cold water as a heat sink. It uses water at 4 to 10 degrees Celsius drawn from deep areas within lakes, oceans, aquifers or rivers, which is pumped through the one side of a heat exchanger .

   If the air is cooler and drier, droplets stay in the air longer, which increases the chances of infecting people nearby. That also happens with air conditioning, which can reduce humidity.
