Health effect:

Anion-vitamin in air Ions are produced when electrons are colliding with molecules in air, and ions with negative charge are called anions. Anions are everywhere in nature and they come out in thunder, lightning, photosynthesis, water flow collision, etc. It is why people may feel fresh air in thundering and raining weathers, in forests or beside waterfalls.


Magical functions of anion 1. Producing active oxygen: negative oxygen ion is able to effectively activate oxygen molecule in air so that it becomes more active and absorbable for people and prevents “air-conditioner diseases”.2. Improving lung functions: after absorbing anions with oxygen, lung will absorb 20% more of oxygen and discharge 15% more of carbon dioxide than it did.3. Promoting metabolism: activating multiple enzymes in body and promoting metabolism.4. Enhancing disease-resistant ability: changing reaction ability of body, activating function of network endothelial system and enhancing immunity. 5. Improving sleep quality: affected by anion, people will feel energetic and efficient in job. By combine the two, it may absorb various viruses and germs, it may change structure or move energy, or even cause death. It serves dust abatement, sterilization, and reduces harm from passive smoking. Its effectiveness and environmental protection and health are visible.


Cooling principle

Water evaporative cooling has a wide range of applications in our daily life. While standing on the beach, one feels very cool; one can also feel the coolness of the breeze as it passes over one’s wet skin… these are where evaporation takes place: The water absorbs heat in the air, thus reducing the air temperature. The natural phenomenon is well explained in the rationale of temperature reduction for Yao Feng pad-and-fan air cools. Having successfully combined advanced technologies with water-evaporative cooling techniques,Yao Feng has designed and manufactured air conditioners that provide co-friendly and energy efficient cooling solutions. According to the natural physical phenomenon of “vapor absorbs heat and size of evaporation affects efficiency of evaporation”, Yao Feng evaporation temperature reduction air change unit gets air through the evaporation wet curtain with real heat exchange area multiplying surface area, absorbs much heat and achieves the effect of reducing temperature.
