Electric heater
Design principle.
Electric heater is a common household electrical equipment. In winter, almost every family must have it.
What is the design principle of electric heater? What is the construction? Next, we will reveal the secret for you!!!
Design principle: the electric heater is heated by the electric heating wire in the electric heater, and then releases heat or infrared ray. When powered on, electric energy is converted into heat energy, and the output capacity is exactly the same as that of later conversion and release.
We take air conditioning as an example. Air conditioning is also divided into many types, such as heat pump air conditioning, electric heating air conditioning and heat pump auxiliary electric heating air conditioning. Heat pump air conditioning uses the refrigeration system inside the air conditioner to absorb outdoor heat, and releases the absorbed outdoor heat to the room by exchanging air to provide heat for the indoor air. However, if the indoor temperature is lower than 5 ℃, the heat pump air conditioner has little effect, because when the indoor temperature is lower than -5 ℃, the evaporation capacity of the refrigerant will decrease. If the indoor temperature is lower than -5 ℃, the refrigerant will not work at all.
The working principle of heating air conditioner and electric heater / electric heater is very similar. They all convert electric energy into heat energy after power on, and then release it. Indoor and outdoor temperature will not affect their working performance.
Electric heater.
Electric heater heater is a kind of equipment that generates warm air by consuming electric energy. During operation, the low-temperature fluid medium enters its input port under pressure through the pipe, and along the specific heat exchange channel inside the electric heating vessel, the path designed by using the principle of fluid thermodynamics takes away the high-temperature heat energy generated by the electric heating element during operation, so as to raise the temperature of the heated medium, and the outlet of the electric heater gets the high-temperature medium required by the process. The internal control system of the electric heater automatically adjusts the output power of the electric heater according to the temperature sensor signal at the output port to make the medium temperature at the output port uniform; When the heating element is overheated, the independent overheat protection device of the heating element immediately cuts off the heating power supply to avoid coking, deterioration and carbonization caused by the overheating of the heating material, which may cause the heating element to burn out in serious cases, effectively extending the service life of the electric heater.
