classification of humidifier

Humidifier is a kind of household electrical appliance that can increase the humidity of the room. Humidifier can humidified the designated room, and it can also be connected with the boiler or the central air conditioning system to the whole building to humidification. According to the theory of heat and moisture exchange, the humidifier is divided into two following parts in practical engineering.

1, equal enthalpy humidifier: that is to absorb water and absorb sensible heat of air to evaporate and humidification. Its change on enthalpy and wet chart is approximately equal enthalpy process.

2, the same temperature humidifier: that is, the use of heat energy to transform liquid water into steam and air mixing to humidification, its change on the enthalpy and wet chart is approximate isothermal process.

Humidifier can be divided into three categories: industrial humidifier, commercial humidifier and household humidifier.

Ultrasonic humidifier

It has been widely used in various fields. The ultrasonic humidifier uses 2 million ultrasonic high-frequency oscillations per second to atomized water from 1 microns to 5 microns of ultrafine particles and negative oxygen ions, so as to achieve even humidification, fresh air, improve health, remove the hot heat in winter and create a comfortable living environment.

Pure humidifier

The direct evaporating humidifier is also known as the pure humidifier. Pure humidification technology is a new technology which has just been used in the field of humidification. Through molecular sieve evaporation technology, removing calcium and magnesium ions in water, the problem of "white powder" is solved thoroughly. By washing the air through the water curtain, the bacteria, dust and particles in the air can be filtered and purified while the air is humidified, and then the moist clean air is sent to the room by the pneumatic device, thus improving the humidity and cleanliness of the environment. So it is very suitable for families with old people and children, and it can also prevent influenza viruses in winter.

The ultrasonic humidifier and the pure humidifier are the preferred products for children to buy, with high safety factor, clean air, strong ability to remove bacteria and humidification, improve health and give children a comfortable environment.

Electric humidifier

The hot steam humidifier is also called the electric heating humidifier. Its working principle is to heat the water in the heating body to 100 degrees, producing steam and sending the steam out of the motor. The electric heating humidifier is the simplest way of humidification.

Immersion electrode humidifier

The immersion type electrode humidifier (immersed Electrode humidifier) is a large area electrode used in the submerged water as the terminal, and water is used as the heating medium. When the electric current is transferred through the water, the heat is generated, and the water is boiling and producing steam. Its characteristics are low cost, easy installation and use. However, its accuracy is low, and it needs regular replacement of humidifier barrel maintenance.

Cold mist humidifier

The humidifier uses a fan to force air to contact and exchange with water to increase relative humidity of air through water absorbing medium. The humidifier is characterized by the ability to automatically adjust the humidity with the relative humidity of the air, that is, when the air relative humidity is low, the humidification is large, the humidity is high and the humidity is low; the disadvantage is that the humidifier is low (about 1/5 of the ultrasonic humidifier), the noise is larger than the ultrasonic humidifier, but the humidifier is less energy consuming and the noise is low.

Commercial humidifier

Commercial humidifier is a medium spray humidifier between civilian and industrial applications.
