  2. Hydronic balancing - Wikipedia

    en.wikipedia.org/wiki/Hydronic_balancing

    In small heating systems (e.g. domestic systems), balancing is quite easy because of the small number of terminal units and relatively simple distribution network. Balancing can normally be achieved by simply pre-setting the flow through the radiators.

  3. Automatic balancing valve - Wikipedia

    en.wikipedia.org/wiki/Automatic_balancing_valve

    A cooling or heating water distribution system is in balance when the flow in the whole system (through the component terminal lines, distributing lines and main distributing lines) corresponds to the flow rates that were specified for the design of the system. If the correct balancing of the system is not established, this will result in ...

  4. Hydronics - Wikipedia

    en.wikipedia.org/wiki/Hydronics

    Despite its name, a radiator does not primarily heat a room by radiation. If positioned correctly a radiator will create an air convection current in the room, which will provide the main heat transfer mechanism. It is generally agreed that for the best results a steam radiator should be no more than one to two inches (2.5 to 5cm) from a wall.

    Heat Rejection - Ammonia passes from the ATA through a two way path of the Flex Hose Rotary Coupler (FHRC) where heat captured while passing through the Heat Exchangers is directed to be expelled through the Heat Rejection System Radiators (HRSRs).

  6. Thermostatic radiator valve - Wikipedia

    en.wikipedia.org/wiki/Thermostatic_radiator_valve

    A thermostatic radiator valve on position 2 (15–17 °C) Installed thermostatic radiator valve with the adjustment wheel removed A thermostatic radiator valve (TRV) is a self-regulating valve fitted to hot water heating system radiator, to control the temperature of a room by changing the flow of hot water to the radiator.

    The heat can be transferred to the surrounding air using radiators, hot water coils (hydro-air), or other heat exchangers. The radiators may be mounted on walls or installed within the floor to produce floor heat. The use of water as the heat transfer medium is known as hydronics. The heated water can also supply an auxiliary heat exchanger to ...

  9. Spacecraft thermal control - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_thermal_control

    The thermal control subsystem can be composed of both passive and active items and works in two ways: Protects the equipment from overheating, either by thermal insulation from external heat fluxes (such as the Sun or the planetary infrared and albedo flux), or by proper heat removal from internal sources (such as the heat emitted by the internal electronic equipment).
