2 Lossnay optimizes residential indoor-air quality through Lossnay is a total heat-exchange ventilation system that utilizes the characteristics of corrugated design for superior temperature (sensible heat) and humidity (latent heat) exchange.* Heat exchange concept applying the Lossnay core Outside Inside Outside exhaust-air outlet (EA) Inside return-air (RA) Outside-air intake (OA) Inside supply-air (SA) After introduction of the first-generation Lossnay in 970, Mitsubishi Electric ventilators have evolved by always being one-step ahead of the air-conditioning needs of the s, which continue to diversify even today. This original technology is now used in a wide range of applications, and our ventilation systems can be found in residences, office buildings, hospitals, schools, etc. *VL-220CZGV-E is a laten heat exchanger for centralized ventilation systems.

3 temperature and humidity exchange The need for ventilation The need for fresh air Poor air quality can be attributed to many problems arising in the workplace and in the home. It is believed to contribute to a significant loss in productivity, low morale and higher rates of sickness. Providing good ventilation in residential and commercial buildings is to provide conditions under which people can live and work comfortably and safely. The need for appropriate humidity management In general, viruses are found to be active and the survival rate high in low-humidity, dry environments. During the winter, keeping the appropriate humidity and heating tempe rature can help prevent viruses. 0 Effect occurs by oxygen concentration Oxygen concentration (%) Normal air concentration 2% Activity range of microorganisms vs. humidity General appropriate humidity range Size of energy Bacteria Virus No danger of risking life in a normal pressure, however it may increase carbon monoxide with combustion appliance 9~20% Mold General oxygen concentration when exhalating Breathing/pulse increases headache, nausea, and dizziness 6% 2~6% Mite Humidity (%) [ Image ] Combustion appliance stops burning 5% Danger of risking life in a short term 2% Causing death 7% What can be improved by introducing Lossnay?
