2. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   Circulating hot water can be used for central heating. Sometimes these systems are called hydronic heating systems. [22] Common components of a central heating system using water-circulation include: A supply of fuel, electric power or district heating supply lines; A boiler (or a heat exchanger for district heating) which heats water in the system

3. Heating system - Wikipedia

   en.wikipedia.org/wiki/Heating_system

   Central heating systems: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat pumps. [1] [2] Distributed heating systems: These systems generate heat in the space they are to heat, without extensive duct systems. Examples include electric space heaters ...

4. Automatic balancing valve - Wikipedia

   en.wikipedia.org/wiki/Automatic_balancing_valve

   In addition, double-regulating balancing valves are manually set to regulate the impact of pressure changes across the system. CAV (constant air volume) systems are mainly used in offices made up of a single area (e.g. open plan), where the temperature of the supply air is varied in response to a thermostat.

5. Hydronic balancing - Wikipedia

   en.wikipedia.org/wiki/Hydronic_balancing

   Hydronic balancing, also called hydraulic balancing, is the process of optimizing the distribution of water in a building's hydronic heating or cooling system by equalizing the system pressure. In a balanced system every radiator is set to receive the proper amount of fluid in order to provide the intended indoor climate at optimum energy ...

6. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   Heaters are appliances whose purpose is to generate heat (i.e. warmth) for the building. This can be done via central heating. Such a system contains a boiler, furnace, or heat pump to heat water, steam, or air in a central location such as a furnace room in a home, or a mechanical room in a large building.

7. Vortex tube - Wikipedia

   en.wikipedia.org/wiki/Vortex_tube

   This approach relies on observation and experimental data. It is specifically tailored to the geometrical shape of the vortex tube and the details of its flow and is designed to match the particular observables of the complex vortex tube flow, namely turbulence, acoustic phenomena, pressure fields, air velocities and many others.
