The working principle of the electric heater The electric heater uses the electric heating wire to emit heat or infrared rays for heating. It converts electric energy into heat energy, so its output energy and input energy are the same.
Air conditioning heating is divided into heat pump type, electric heating type, and heat pump auxiliary electric heating type. The heat pump type air conditioner absorbs heat from the outside through the refrigeration system and then releases it to the room. It is only the transfer of heat. When the outdoor temperature is not lower than 5 degrees, the heat pump type air conditioner emits 2 to 3 times the input power, so In this case, the heat pump type air conditioner saves much electricity than the electric heater.
However, when the room temperature is lower than 5 degrees, the heating capacity of the heat pump type air conditioner will decrease due to the reduction of the refrigerant evaporation capacity. When the temperature is lower than -5 degrees, it may not be able to heat normally. The principle of the electric heating type air conditioner is different from that of the heat pump type, and the principle is similar to that of the electric heating type. Both directly convert electric energy into heat energy and then release it. It has nothing to do with the outdoor temperature, and the power consumption is also the same.
The heat pump auxiliary electric heating type air conditioner adds electric heating elements on the basis of the heat pump type. When the outdoor temperature is high, the heat pump type is used to save electricity. When the outdoor temperature is too low, the electric heating element is used for heating. So as long as the outdoor temperature is not lower than 5 degrees, it is obvious to use the air conditioner to heat and save electricity.
