The LOSSNAY inspired by a daughter playing with paper

It was new years 1969, when Masataka Yoshino an engineer in the air-conditioning department at Mitsubishi Electric was thinking of ways to improve output efficiency that the essence of the energy recovery ventilator concept hit him. It was when Mr. Yoshino watched his 2-year old daughter make a paper tube that the idea came to him in a flash. He immediately grasped the meaning of the paper tube. It was possible to use rolled up paper to expel cold or hot air while transferring heat and humidity at the same time. Try this easy experiment yourself. Roll a piece of paper into a round tube and blow into it. The humidity and temperature of the breath will by transmitted through the paper to the hands holding the tube. This was the fundamental principle for the LOSSNAY.

Now apply this concept to air-conditioners. Funnel cooled but dirty indoor air out through a paper straw. Attach at length another paper straw to flow through it warm but fresh outdoor air. Although both are separated and not in direct contact, this medium forces the cool but dirty indoor air and warm but fresh outdoor air to permeate through the paper barrier. This exchange of the temperatures and humidity is how efficient ventilation is achieved.
