The working principle of hot air curtain

Steam hot air curtain

Hot air curtain is through the high speed motor drive tubular or centrifugal wind turbines generate strong airflow, forming a invisible door curtain. Therefore, also known as the wind curtain machine, air curtain, air wind curtain machine, air brake, air door, electric hot air curtain is to use the electric heating wind curtain machine.

The working principle of the editor

Hot air curtain is the electrical energy is converted into heat energy of high-power electrical equipment, because of its large heat and safe and reliable, wide use, has got the market favour. Hot air curtain is generally not equipped with air filter unit, because install air filter, increase the air intake resistance and reduce the number of inlet, also increased the load - heater (heater consists of a number of PTC ceramic composite) when the hot air curtain electricity that is, when the heater and fan work after work, after electrify PTC ceramic film rapidly warming, the wind of the fan out and now PTC ceramic high-temperature heat away on the surface, the lower the surface temperature of PTC ceramic chip. If increased the air filter, reduce the speed of the air through the PTC ceramic surface, so as to improve the working temperature of the PTC ceramic piece, make it always in high temperature working condition, when the temperature reaches temperature PTC ceramic chip design protection, PTC ceramic chip inside, will automatically power off at this time although the voltage on the ends of the PTC ceramic chip, PTC ceramic chip also won't work, also won't produce heat, but if the heater is always working in the condition of the environment, PTC ceramics on and off frequently, mass attenuation performance of PTC ceramic chip, also can make PTC ceramic surface by overheating and accelerate the aging, that is to say, consumes energy, but didn't get the same heat. In the long run, will cause the electricity (electricity) the consequences of not heating.

Although hot air curtain is generally not add air filters, but there will be a lot of dust particles in the air, the particles will work with hot air curtain into the surface of the heater in the hot air curtain, air curtain use the longer, the dust particles in the air accumulated in the surface of the heater will be thick, it will affect the cooling speed of PTC ceramic chip cooling speed (heater), increases the overall temperature of the hot air curtain body, may also affect the stability of the fan, affect the service life of heater.
