2. Dedicated outdoor air system - Wikipedia

   en.wikipedia.org/wiki/Dedicated_outdoor_air_system

   DOAS air handling unit with heat recovery wheel and passive dehumidification. A dedicated outdoor air system (DOAS) is a type of heating, ventilation and air-conditioning system that consists of two parallel systems: a dedicated system for delivering outdoor air ventilation that handles both the latent and sensible loads of conditioning the ventilation air, and a parallel system to handle the ...

3. Chiller - Wikipedia

   en.wikipedia.org/wiki/Chiller

   A liquid (glycol based) chiller with an air cooled condenser on the rooftop of a medium size commercial building. In air conditioning systems, chilled coolant, usually chilled water mixed with ethylene glycol, from a chiller in an air conditioning or cooling plant is typically distributed to heat exchangers, or coils, in air handlers or other types of terminal devices which cool the air in ...

   Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. [32] (Minisplit ...

5. HVAC control system - Wikipedia

   en.wikipedia.org/wiki/HVAC_control_system

   All HVAC systems have an intake, air filter, and air conditioning liquid. However, when designing HVAC systems, many engineers design it for a specific setting and/or purpose. When engineers are designing an HVAC system, they try their best to make it compact while still being able to perform at the highest level and experiment with different ...
