  2. Chilled water - Wikipedia

    en.wikipedia.org/wiki/Chilled_water

    A chiller used to create chilled water as part of a chilled water system. Chilled water is a commodity often used to cool a building's air and equipment, especially in situations where many individual rooms must be controlled separately, such as a hotel. The chilled water can be supplied by a vendor, such as a public utility, or created at the ...

  3. Free cooling - Wikipedia

    en.wikipedia.org/wiki/Free_cooling

    The cooling tower water can be directly linked into the flow through the chilled water circuit. If the cooling tower is open then a strainer is required to eliminate any debris that could accumulate within the tower. The cost savings are associated with the limited use of the water chiller energy. There is an increased risk of corrosion using ...

    en.wikipedia.org/wiki/Thermal_expansion_valve

    A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible.A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator.

  6. Heat transfer coefficient - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer_coefficient

    There are also online calculators available specifically for Heat-transfer fluid applications. Experimental assessment of the heat transfer coefficient poses some challenges especially when small fluxes are to be measured (e.g. < 0.2 W/cm 2). [1] [2]

  7. Searle's bar method - Wikipedia

    en.wikipedia.org/wiki/Searle's_bar_method

    ΔQ is the heat supplied to the bar in time Δt; k is the coefficient of thermal conductivity of the bar. A is the cross-sectional area of the bar, ΔT bar is the temperature difference between each end of the bar; L is the length of the bar; and the heat ΔQ absorbed by water in a time interval of Δt is:
