Working Principle - WOOD'S WHU400 Manual De Instrucciones

Working principle

Working principle: Ultrasonic humidifiers use a high frequency oscillator to break up the water
into tiny particles. The ventilation system of the humidifier fans the water into the air where they
evaporate, increasing the humidity.

What is air humidity?
Air humidity is the water vapour content in the air.
What is relative humidity?
Relative humidity is the proportion of moisture or water vapour in the air in relation to the maxi-
mum possible level at the current temperature, expressed as a percentage.
How can insufficient humidity affect us?
When the air is too dry, hydrogen levels in the body decrease, and negative symptoms can occur
or be aggravated. Common symptoms are
• Nasal congestion or runny nose
• Breathing difficulties
• Dry throat; sore throat
• Dry complexion with flaking and skin cracking
• Static electricity
• Tiredness, drowsiness and poor concentration
• Respiratory infections and diseases, such as asthma.
• Problems with dry complexion and eczema
• Dry eyes; smarting
What is ideal relative humidity?
In tropical countries, the climate is extremely hot and humid. This is why air-conditioning systems
are used everywhere. The disadvantage of air conditioning is that it makes the air much too dry.
A comfortable indoor environment with relative humidity of 60% to 70% is recommended.
