about

Humidifier is a kind of household appliance that can increase room humidity. Humidifier can humidify a designated room, or it can be connected to a boiler or central air-conditioning system to humidify the whole building. According to the heat and moisture exchange theory, humidifiers are divided into the following two types in practical projects:
1. Constant enthalpy humidifier: it uses water to absorb the sensible heat of air for evaporative humidification, and its change on the enthalpy and humidity chart is an approximate constant enthalpy process.
2. Isothermal humidifier: it converts liquid water into steam and mixes it with air for humidification by using heat energy. Its changes on the enthalpy and humidity chart are approximate isothermal processes.
Humidifiers can be divided into three categories: industrial humidifiers, commercial humidifiers and household humidifiers.
Ultrasonic humidifier
It has been widely used in various fields. The ultrasonic humidifier uses 2 million high-frequency ultrasonic oscillations per second to atomize water into ultrafine particles and negative oxygen ions of 1 to 5 microns, so as to achieve uniform humidification, fresh air, improve health, remove the dryness and heat of heating in winter, and create a comfortable living environment.
Pure humidifier
Direct evaporative humidifier is also known as pure humidifier. The pure humidification technology is a new technology just adopted in the field of humidification. Through molecular sieve evaporation technology, calcium and magnesium ions in water are removed, and the "white powder" problem is completely solved. Washing air through water curtain can filter and purify bacteria, dust and particles in the air while humidifying, and then send the moist and clean air to the room through the pneumatic device, thus improving the environmental humidity and cleanliness. So it is very suitable for families with elderly and children, and can also prevent winter flu germs.
Ultrasonic humidifier and pure humidifier are recommended to be the first choice for children. They have high safety coefficient, strong ability of purifying air, sterilizing and humidification, improve health, and provide a comfortable environment for children.

Electric heating humidifier
The thermal evaporative humidifier is also called electric heating humidifier. Its working principle is to heat the water in the heater to 100 ℃, generate steam, and send the steam out with the motor. Electric heating humidifier is the simplest humidification method.
Immersion electrode humidifier
Immersed electrode humidifier uses a large area of electrodes immersed in water as terminals and water as the heating medium. When the current transfers electric energy through water, it generates heat, boiling water and steam. It is characterized by low cost, easy installation and use, but low accuracy, and the need for regular replacement of humidifying barrel maintenance.
Cold fog humidifier
The humidifier makes use of the fan to force the air to contact and exchange with water when passing through the water absorbing medium to increase the relative humidity of the air. This humidifier is characterized by automatic adjustment with the relative humidity of the air, that is, when the relative humidity of the air is low, the humidification amount is large, and when the relative humidity of the air is high, the humidification amount is low; The disadvantage is that the humidification amount is low (about 1/5 of that of the ultrasonic humidifier), and the noise is higher than that of the ultrasonic humidifier. However, this kind of humidifier consumes less energy and has low noise.
Commercial humidifier
Commercial humidifier is a kind of humidification equipment with medium spray volume between civil and industrial use.
Commercial humidifiers shall have the following characteristics:
1. Commercial humidifier has medium spray volume. It can't be too small. The commercial space is more than 100 square meters. Too small humidification is meaningless.
2. Commercial humidifiers should work reliably. The failure rate of the work with low requirements in the commercial environment.
3. Commercial humidifiers should be easy to maintain. Any commercial environment is a long-term work, and equipment that cannot be maintained is not suitable for use.
4. Commercial humidifiers should be as energy-efficient as possible. The long-term commercial environment has a strong demand for energy conservation.
5. Volume of commercial humidifier. Commercial environment is generally compact and tends to miniaturize the volume of humidification equipment.
6. Water supply of commercial humidifiers. The commercial environment is complex, which requires diversified water supply for humidifiers. The water supply mode should be flexible and convenient.
Commercial humidifier is applicable to mahjong room, chess and card room, KTV, beauty salon, hotel, family, entertainment place, office, bank, hospital, school, government agency and other indoor places.
Its working principle is to make the humidifier release pure substance ozone (O3) while atomizing water through electrolysis method. O3 plays the role of sterilization and disinfection of water quality in the process of water atomization, and spreads to all corners of the room along with the uniform humidification mist, which plays the role of purifying air. The pure substance ozone (O3) released by the oxygen bar humidifier is a famous powerful and pure "purifying agent", Ozone is a good way to continuously remove bacteria and viruses in high purity water systems.
