  2. Flex sensor - Wikipedia

    en.wikipedia.org/wiki/Flex_sensor

    A flex sensor or bend sensor is a sensor that measures the amount of deflection or bending. Usually, the sensor is stuck to the surface, and resistance of sensor element is varied by bending the surface. Since the resistance is directly proportional to the amount of bend it is used as goniometer, and often called flexible potentiometer.

  3. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    Water heaters that instantly heat water as it flows through the device. The inside of a hydraulically operated two-stage tankless heater, heated by single-phase electric power. The copper tank contains heating elements with 7.2 kW maximum power. Tankless water heaters — also called instantaneous, continuous flow, inline, flash, on-demand, or ...

  4. Heat flux sensor - Wikipedia

    en.wikipedia.org/wiki/Heat_flux_sensor

    A heat flux sensor is a transducer that generates an electrical signal proportional to the total heat rate applied to the surface of the sensor. The measured heat rate is divided by the surface area of the sensor to determine the heat flux. Silicon encased heat flux sensor for measurements on rugged surfaces.

  5. 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.

  6. Thermopile - Wikipedia

    en.wikipedia.org/wiki/Thermopile

    This voltage output from the sensor's thermopile is initially calibrated in order to relate it to heat flux. A thermopile is an electronic device that converts thermal energy into electrical energy. [1] It is composed of several thermocouples connected usually in series or, less commonly, in parallel. Such a device works on the principle of the ...

  7. 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 ...

  8. Fan coil unit - Wikipedia

    en.wikipedia.org/wiki/Fan_coil_unit

    A fan coil unit (FCU), also known as a Vertical Fan Coil Unit (VFCU), is a device consisting of a heat exchanger (coil) and a fan. FCUs are commonly used in HVAC systems of residential, commercial, and industrial buildings that use ducted split air conditioning or central plant cooling. FCUs are typically connected to ductwork and a thermostat ...

  9. Thermostat - Wikipedia

    en.wikipedia.org/wiki/Thermostat

    A thermostat is a regulating device component which senses the temperature of a physical system and performs actions so that the system's temperature is maintained near a desired setpoint. Thermostats are used in any device or system that heats or cools to a setpoint temperature.
