Lossnay Structure


Less

The Lossnay core is a crossflow plate-fin total heat exchanger composed of partition plates and spacer plates made of special processed paper. As the air-supply and -exhausting passages are completely separated by partition plates, fresh air is constantly introduced with no mixing of fresh and stale air.

Principle of Heat Exchange


More
  • Temperature (sensible heat) exchange

From the warmer to the cooler side, heat is conducted and passes through the partition plates.

  • Humidity (latent heat) exchange

Due to the difference in the water-vapor partial pressure, water vapor is transferred from the high-humidity side to the low-humidity side through the partition plates.

Heat exchange and save energy


More

The air conditioner needs not be so powerful which help saving energy. 

Excellent sound insulation


More

The structure of the Lossnay core transmits little air vibration and absorbs sound. Lossnay is approved as noise control equipment for houses in noisy areas near airports, and is also used in areas near railroads and highways.

High durability
