  2. Thermoelectric cooling - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_cooling

    Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

  3. Glow plug - Wikipedia

    en.wikipedia.org/wiki/Glow_plug

    Glow plug. In a diesel engine, a glow plug (also spelled glowplug) is a heating device used to aid starting of the engine in cold weather. This device is a pencil-shaped piece of metal with an electric heating element at the tip. A glowplug system consists of either a single glowplug in the inlet manifold, or one glowplug per cylinder.

    en.wikipedia.org/wiki/COM-HPC

    The computer-on-module for high performance compute (COM-HPC) form factor standard targets high I/O and computer performance levels. Each COM-HPC module integrates core CPU and memory functionality and input and output including USB up to Gen 4, audio (MIPI SoundWire, I2S and DMIC), graphics, (PCI Express) up to Gen. 5, and Ethernet up to 25 ...

  5. Thermoelectric effect - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_effect

    v. t. e. The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. [1] A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a ...

  6. 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 ...

  7. Thermal expansion valve - Wikipedia

    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. As a refrigerant passes through a circuit containing these four elements, air ...

  8. Thermoacoustic heat engine - Wikipedia

    en.wikipedia.org/wiki/Thermoacoustic_heat_engine

    A thermoacoustic device takes advantages of the fact that in a sound wave parcels of gas adiabatically alternatively compress and expand, and pressure and temperature change simultaneously; when pressure reaches a maximum or minimum, so does the temperature. It basically consists of heat exchangers, a resonator and a stack (on standing wave ...
