  2. Autovent - Wikipedia

    en.wikipedia.org/wiki/Autovent

    An autovent is a device for maintaining a greenhouse or conservatory within a range of temperatures. The basic principle is that as greenhouse heats above ambient the air inside becomes lighter, the vent opens when a certain temperature is reached and lets the hot air out - drawing cooler air in from outside.

  3. Ground-coupled heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

    An alternative to the earth-to-air heat exchanger is the "water" to earth heat exchanger. This is typically similar to a geothermal heat pump tubing embedded horizontally in the soil (or could be a vertical sonde) to a similar depth of the earth-air heat exchanger. It uses approximately double the length of pipe of 35 mm diameter, e.g., around ...

  4. Heat recovery ventilation - Wikipedia

    en.wikipedia.org/wiki/Heat_recovery_ventilation

    Ventilation unit with heat pump & ground heat exchanger - cooling. Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR) is a ventilation system that recovers energy by operating between two air sources at different temperatures. It is used to reduce the heating and cooling demands of buildings.

  5. Fan coil unit - Wikipedia

    en.wikipedia.org/wiki/Fan_coil_unit

    The equipment used can consist of machines used to remove heat such as a chiller or a cooling tower and equipment for adding heat to the building's water such as a boiler or a commercial water heater. Hydronic fan coil units can be generally divided into two types: Two-pipe fan coil units or four-pipe fan coil units. Two-pipe fan coil units ...

  6. Ventilative cooling - Wikipedia

    en.wikipedia.org/wiki/Ventilative_cooling

    Ventilative cooling is the use of natural or mechanical ventilation to cool indoor spaces. [1] The use of outside air reduces the cooling load and the energy consumption of these systems, while maintaining high quality indoor conditions; passive ventilative cooling may eliminate energy consumption.

  7. 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.

  9. Thermosiphon - Wikipedia

    en.wikipedia.org/wiki/Thermosiphon

    The thermosiphon has been sometimes incorrectly described as a 'gravity return heat pipe'. [3] Heat pipes usually have a wick to return the condensate to the evaporator via capillary action. A wick is not needed in a thermosiphon because gravity moves the liquid. [4] The wick allows heat pipes to transfer heat when there is no gravity, which is ...
