2. Evaporative cooler - Wikipedia

   en.wikipedia.org/wiki/Evaporative_cooler

   However, in the example of Salt Lake City, the upper limit for the direct evaporative cooling on psychrometric chart is 20 °C (68 °F). Despite the lower temperature, evaporative cooling is suitable for similar climates to Salt Lake City. Evaporative cooling is especially well suited for climates where the air is hot and humidity is low.

3. Ground-coupled heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

   The closed loop system can be more effective cooling the air (during air temperature extremes) than an open system, since it cools and recools the same air. Open system: Outside air is drawn from a filtered air intake (Minimum Efficiency Reporting Value MERV 8+ air filter is recommended) to cool or preheat the air. The tubes are typically 30 m ...

4. Air conditioning - Wikipedia

   The output of the infrared LED (like that of any infrared remote) is invisible to the human eye because its wavelength is beyond the range of visible light (940 nm). This system is commonly used on mini-split air conditioners because it is simple and portable. Some window and ducted central air conditioners uses it as well.

5. Register (air and heating) - Wikipedia

   en.wikipedia.org/wiki/Register_(air_and_heating)

   Usually, a register is placed near a window or door, which is where the greatest heat/cooling loss occurs. [4] [5] In contrast, returns (grilled ducts which suck air back into the HVAC system for heating or cooling) are usually placed in the wall or ceiling nearest the center of the building. Generally, in rooms where it is critical to maintain ...

6. Chilled beam - Wikipedia

   en.wikipedia.org/wiki/Chilled_beam

   A chilled beam is a type of radiation/convection HVAC system designed to heat and cool large buildings through the use of water. [1] This method removes most of the zone sensible local heat gains and allows the flow rate of pre-conditioned air from the air handling unit to be reduced, lowering by 60% to 80% the ducted design airflow rate and the equipment capacity requirements.
