  2. ASHRAE 90.1 - Wikipedia

    en.wikipedia.org/wiki/ASHRAE_90.1

    ANSI/ASHRAE/IES Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings is an American National Standards Institute (ANSI) standard published by ASHRAE and jointly sponsored by the Illuminating Engineering Society (IES) that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings (i.e. single-family homes ...

  3. Water (data page) - Wikipedia

    en.wikipedia.org/wiki/Water_(data_page)

    Data in the table above is given for water–steam equilibria at various temperatures over the entire temperature range at which liquid water can exist. Pressure of the equilibrium is given in the second column in kPa. The third column is the heat content of each gram of the liquid phase relative to water at 0 °C.

  4. Evaporative cooler - Wikipedia

    en.wikipedia.org/wiki/Evaporative_cooler

    Cooling towers are structures for cooling water or other heat transfer media to near-ambient wet-bulb temperature. Wet cooling towers operate on the evaporative cooling principle, but are optimized to cool the water rather than the air. Cooling towers can often be found on large buildings or on industrial sites.

  5. Chiller boiler system - Wikipedia

    en.wikipedia.org/wiki/Chiller_boiler_system

    Chiller boiler systems use radiant heating and cooling or fan coil systems to condition a home or business. This allows for multiple zones (a thermostat in each living area of the house) for increased comfort and decreased energy use. Compared with air, water is a more space-efficient method of transferring heat around, into, and out of a building.

  6. Cooling tower - Wikipedia

    en.wikipedia.org/wiki/Cooling_tower

    A typical evaporative, forced draft open-loop cooling tower rejecting heat from the condenser water loop of an industrial chiller unit Natural draft wet cooling hyperboloid towers at Didcot Power Station (UK) Forced draft wet cooling towers (height: 34 meters) and natural draft wet cooling tower (height: 122 meters) in Westphalia, Germany Natural draft wet cooling tower in Dresden (Germany)

  7. Chilled water - Wikipedia

    en.wikipedia.org/wiki/Chilled_water

    The cooling towers of a large chilled water system. As part of a chilled water system, the condenser water absorbs heat from the refrigerant in the condenser barrel of the water chiller and is then sent via return lines to a cooling tower, which is a heat exchange device used to transfer waste heat to the atmosphere.

  8. Coefficient of performance - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_performance

    The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [ 1 ] [ 2 ] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.

  9. Glossary of HVAC terms - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_HVAC_terms

    The condenser is the hot side of an air conditioner or heat pump. Condensers are heat exchangers, and can transfer heat to air or to an intermediate fluid (such as water or an aqueous solution of ethylene glycol) to carry heat to a distant sink, such as ground (earth sink), a body of water, or air (as with cooling towers). constant air volume
