  3. Hydronic balancing - Wikipedia

    en.wikipedia.org/wiki/Hydronic_balancing

    Avoiding overflows means the pump is not doing unnecessary work which saves energy, reduces operating cost and can reduce the size of the pump required (saving on the initial pump investment). Balancing also saves energy and operating costs by reducing the amount of time between starting a plant and reaching the required indoor climate.

  4. 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.

  5. Thermal expansion valve - Wikipedia

    en.wikipedia.org/wiki/Thermal_expansion_valve

    A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in vapor-compression refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the refrigerant that flows out of the evaporator ...

  6. Automatic balancing valve - Wikipedia

    en.wikipedia.org/wiki/Automatic_balancing_valve

    Pressure independent control valves are used to limit the flow to the fan coil terminal and air handling unit. This flow is not affected by changes in inlet pressure. A diaphragm within the valve keeps the outlet pressure constant, and this delivers a constant flow to the terminal. The added advantage of pressure independent control valves is ...

  7. Automatic bleeding valve - Wikipedia

    en.wikipedia.org/wiki/Automatic_bleeding_valve

    A dry valve acts as an air vent until a dribble of water passes through it and swells the cartridge. If the valve dries out again, it re-opens. A characteristic of these valves is that they function best on the hot delivery side of a radiator and may not open as vents unless the water supply is hot. [8]

    Gas stations are routine stops for most people, but they also present opportunities for criminals to take advantage of those who are unaware. Before you fill up your tank next time, it's important ...

  9. Recuperator - Wikipedia

    en.wikipedia.org/wiki/Recuperator

    Compared to alternatives such as regenerative furnaces, initial costs are lesser, there are no valves to be switching back and forth, there are no induced-draft fans and it does not require a web of gas ducts spread up all over the furnace. Historically the recovery ratios of recuperators compared to regenerative burners were low. However ...
