  2. Condensate pump - Wikipedia

    en.wikipedia.org/wiki/Condensate_pump

    In industrial steam systems the condensate pump is used to collect and return condensate from remote areas of the plant. The steam produced in the boiler can heat equipment and processes a considerable distance away. Once steam is used it turns to hot water or condensate. This pump and possibly many more around the plant returns this hot water ...

  3. HVAC control system - Wikipedia

    en.wikipedia.org/wiki/HVAC_control_system

    HVAC control system. HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be ...

  4. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    Central heating. A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat.

  5. Water heating - Wikipedia

    en.wikipedia.org/wiki/Water_heating

    Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses. Domestically, water is traditionally heated in vessels known as water heaters ...

  6. Condensing boiler - Wikipedia

    en.wikipedia.org/wiki/Condensing_boiler

    Condensing boiler. Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the ...

  7. Drip irrigation - Wikipedia

    en.wikipedia.org/wiki/Drip_irrigation

    Drip irrigation. Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation.

  8. Hydronics - Wikipedia

    en.wikipedia.org/wiki/Hydronics

    Hydronics (from Ancient Greek hydro- 'water') is the use of liquid water or gaseous water (steam) or a water solution (usually glycol with water) as a heat-transfer medium in heating and cooling systems. [1][2] The name differentiates such systems from oil and refrigerant systems. Historically, in large-scale commercial buildings such as high ...

  9. Pulse drip irrigation - Wikipedia

    en.wikipedia.org/wiki/Pulse_drip_irrigation

    Pulse drip irrigation is an experimental irrigation technique primarily used with drip irrigation. Maintaining a high level of soil moisture for germination of seed is one reason this technique may be used. Most conventional drip irrigation systems can be made to pulse by using a timer to reduce the watering duration and increase the watering ...
