Dry weather causes discomfort felt through the skin, prompting many to use air humidifiers at home. But do you know how air humidifiers work? What precautions should be taken? Today we'll explain how to use air humidifiers correctly.It can humidify a specific room or be connected to a boiler or central air conditioning system to humidify an entire building.
Most household humidifiers on the market use ultrasonic technology to atomize water. A fan then blows the atomized mist out of the unit, achieving air humidification. The electrical schematic is shown in the attached diagram.Mains power passes through a switching power supply, outputting two voltages: 36V and 12V. The 36V powers the water vapor atomization module, while the 12V powers the fan. In the circuit, D1 and D2 are the low-water indicator and operational indicator lights, respectively; the reed switch serves as the liquid level detection switch; and RT1 is the mist intensity adjustment potentiometer. The ultrasonic generator circuit centers around the 02 chip and its peripheral components.
The ultrasonic humidifier employs high-frequency ultrasonic oscillation at 1.7 MHz to atomize water into ultra-fine particles of 1-5 microns. This refreshes the air, promotes health, and creates a comfortable environment.
According to experts, ultrasonic humidifiers offer significant advantages: high humidification intensity, uniform distribution, and superior efficiency. They are energy-efficient, consuming only 1/10 to 1/15 the electricity of electric heat humidifiers. With a long service life, they feature automatic humidity balancing and dry-run protection. Additional functions include medical nebulization, cold facial misting, and jewelry cleaning.
Direct evaporation humidifiers are also commonly known as pure humidifiers. Pure humidification technology represents a newly adopted innovation in humidification. These humidifiers utilize molecular sieve evaporation technology to remove calcium and magnesium ions from water, completely eliminating the "white powder" issue.
Heat-evaporative humidifiers, also known as electric heating humidifiers, operate by heating water to 100°C within a heating element to produce steam, which is then dispersed by a fan. This makes electric heating humidifiers the simplest humidification technology. However, their drawbacks include high energy consumption, inability to operate dry, lower safety ratings, and susceptibility to scale buildup on the heating element.Market prospects are not optimistic. Electric humidifiers are typically used in conjunction with central air conditioning systems and rarely operate independently.
Comparing the three types: Electric humidifiers eliminate "white powder" residue and operate quietly but consume significant power and are prone to scale buildup. Pure humidifiers also prevent "white powder" and scale formation, feature low power consumption, incorporate air circulation systems, and can filter air while eliminating bacteria.
Ultrasonic humidifiers deliver strong and uniform humidification with low power consumption and long service life. They also serve multiple functions like medical nebulization, cold facial compresses, and jewelry cleaning. Therefore, ultrasonic and pure-type humidifiers remain the recommended top choices.
Usage Precautions
1. Allow the unit to stand at room temperature for 30 minutes before initial operation.
2. Operate within ambient temperatures of 10-40°C (50-104°F).
3. Use clean water below 40°C (104°F).
4. Keep away from other appliances while in operation.
5. Do not add non-professional additives to the water.
6. Avoid placing the humidifier on hollow objects to prevent resonance noise.
7. Do not operate the unit without water. Ultrasonic humidifiers convert electrical energy into mechanical energy via transducers. An oscillation circuit generates 1.7 million high-frequency vibrations per second, directly converting water into ultra-fine particles <5 microns. A fan then disperses these water molecules into the surrounding air.The transducer surface easily accumulates mineral deposits during operation. Failure to perform regular maintenance and cleaning will increase the transducer's operational load, causing the machine to malfunction. We recommend using distilled or purified water to effectively extend the machine's lifespan.
Strictly prohibit any additives in the humidifier water tank: Humidifiers differ from aromatherapy diffusers. Standard humidifiers are not corrosion-resistant. Adding substances not only compromises long-term functionality but may also pose health risks.
The above briefly explains the working principle of air humidifiers and outlines key usage precautions, aiming to enhance your understanding of these devices.
