  3. Air conditioning - Wikipedia

    en.wikipedia.org/wiki/Air_conditioning

    An air conditioner designed for an occupied space will typically achieve a 30% to 60% relative humidity in the occupied space. [51] Most modern air-conditioning systems feature a dehumidification cycle during which the compressor runs. At the same time, the fan is slowed to reduce the evaporator temperature and condense more water.

  4. Solar air conditioning - Wikipedia

    en.wikipedia.org/wiki/Solar_air_conditioning

    Solar in this case is inverted to alternating current (AC) to run the appliances in the house or building, including the air conditioner(s). The advantage of this is the air conditioners don’t need any special electronics to accommodate solar, so it’s a simple implementation.

    en.wikipedia.org/wiki/Fan_coil_unit

    These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.

  7. Variable air volume - Wikipedia

    en.wikipedia.org/wiki/Variable_air_volume

    Air volume regulator. Variable air volume (VAV) is a type of heating, ventilating, and/or air-conditioning system.Unlike constant air volume (CAV) systems, which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a constant or varying temperature.
