  2. Humidifier - Wikipedia

    en.wikipedia.org/wiki/Humidifier

    The amount of minerals and other materials can be greatly reduced by using distilled water. Special disposable demineralization cartridges may also reduce the amount of airborne material, but the EPA warns, "the ability of these devices to remove minerals may vary widely." [16] The mineral dust may have negative health effects.

  3. 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.

  4. Coolant - Wikipedia

    en.wikipedia.org/wiki/Coolant

    Light water reactors, both boiling water and pressurised water reactors the most common type, use ordinary (light) water. Some designs, e.g. CANDU reactor, use both types; heavy water in the nonpressurized calandria tank as the moderator and a supplementary coolant, and light water as the primary heat transfer fluid.

  5. Waterless coolant - Wikipedia

    en.wikipedia.org/wiki/Waterless_coolant

    Older cars often have non-pressurized cooling systems, and the water-based coolant can boil and overflow. Traditionally, this issue has been solved by topping off the radiator with water. This dilutes the coolant and the water can contain minerals harmful to the vehicle. Classic car owners have adopted waterless coolant to solve this problem.

  6. Water cooling - Wikipedia

    en.wikipedia.org/wiki/Water_cooling

    Water is inexpensive, non-toxic, and available over most of the earth's surface.Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer.

    Space heaters can help, but use with caution. Many homeowners may be tempted to rely on fireplaces, space heaters, electric blankets and wood-burning stoves to keep warm in the winter.

    en.wikipedia.org/wiki/Automatic_bleeding_valve

    The top has a small outlet, usually hidden beneath a plastic dust cap. Internally there is a large hollow body, normally filled with water, and containing a float valve. The valve must always be installed vertically, usually at the top of a short vertical pipe. If the valve body is filled with water, the float moves upwards and closes the valve.

  9. Internal combustion engine cooling - Wikipedia

    en.wikipedia.org/wiki/Internal_combustion_engine...

    For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and ...
