  2. Programmable thermostat - Wikipedia

    en.wikipedia.org/wiki/Programmable_thermostat

    A rechargeable battery operates the thermostat just as in the clock thermostat, charging when the thermostat is not calling and discharging while the thermostat is calling. A non-rechargeable battery always powers the thermostat. To limit the amount of power drawn from the battery, such thermostats use an impulse relay that does not require the ...

  3. Heat detector - Wikipedia

    en.wikipedia.org/wiki/Heat_detector

    A residential heat detector. A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All heat detectors have this thermal lag. Heat detectors have ...

  4. Thermostat - Wikipedia

    en.wikipedia.org/wiki/Thermostat

    A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control.

    According to the U.S. Department of Energy, people can save up to 10% per year on heating and cooling expenses by dialing their thermostat back eight hours a day from its normal setting, between 7 ...

  6. Smart thermostat - Wikipedia

    en.wikipedia.org/wiki/Smart_thermostat

    The gas savings for manual thermostat replacements (10% per thermostat) was found to be larger than for programmable thermostat replacements (8% per thermostat). The difference in electricity savings between homes whose prior equipment was a manual thermostat or programmable thermostat was found to be minimal.

    The heat flow can be modelled by analogy to an electrical circuit where heat flow is represented by current, temperatures are represented by voltages, heat sources are represented by constant current sources, absolute thermal resistances are represented by resistors and thermal capacitances by capacitors.

  8. Bimetallic strip - Wikipedia

    en.wikipedia.org/wiki/Bimetallic_strip

    Heat engines are not the most efficient ones, and with the use of bimetallic strips the efficiency of the heat engine is even lower as there is no chamber to contain the heat. Moreover, the bimetallic strips cannot produce strength in its moves, the reason why is that in order to achieve reasonables bendings (movements) both metallic strips ...

  9. Temperature control - Wikipedia

    en.wikipedia.org/wiki/Temperature_control

    Temperature measuring and controlling module for microcontroller experiment. Temperature control is a process in which change of temperature of a space (and objects collectively there within), or of a substance, is measured or otherwise detected, and the passage of heat energy into or out of the space or substance is adjusted to achieve a desired temperature.
