2. Kerosene heater - Wikipedia

   en.wikipedia.org/wiki/Kerosene_heater

   The Japanese non-vented "fan" heater burns kerosene gas and is known as a gasification type heater. The liquid kerosene fuel is pre-heated via an electric heating element to vaporize the fuel. The resulting gas is collected and forced into the burn chamber where it is ignited and burns with a blue flame, similar to propane.

3. Heat recovery ventilation - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_ventilation

   Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...

4. Fan heater - Wikipedia

   en.wikipedia.org/wiki/Fan_heater

   Electric fan heater. A fan heater, also called a blow heater, is a heater that works by using a fan to pass air over a heat source (e.g. a heating element). [1] This heats up the air, which then leaves the heater, warming up the surrounding room. They can heat an enclosed space such as a room faster than a heater without a fan, [2] but like any ...

5. Greenhouse effect - Wikipedia

   en.wikipedia.org/wiki/Greenhouse_effect

   The greenhouse effect occurs when greenhouse gases in a planet's atmosphere insulate the planet from losing heat to space, raising its surface temperature. Surface heating can happen from an internal heat source (as in the case of Jupiter ) or come from an external source, such as its host star .

6. Ventilation (architecture) - Wikipedia

   en.wikipedia.org/wiki/Ventilation_(architecture)

   An axial belt-drive exhaust fan serving an underground car park. This exhaust fan's operation is interlocked with the concentration of contaminants emitted by internal combustion engines. Mechanical ventilation of buildings and structures can be achieved by the use of the following techniques: Whole-house ventilation; Mixing ventilation

7. Ground-coupled heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

   Single-pass earth air heat exchangers offer the potential for indoor air quality improvement over conventional systems by providing an increased supply of outdoor air. In some configurations of single-pass systems, a continuous supply of outdoor air is provided. This type of system would usually include one or more ventilation heat recovery units.
