Examples of Lossnay Applications
2.4 Outcome
(1) Appropriate ventilation was possible with forced simultaneous air intake/exhaust using Lossnay units.
(2) Outdoor air to the toilet and kitchenette was possible with Lossnay units, and appropriate ventilation was possible even in
highly sealed buildings.
(3) Odors infiltrating into other rooms was prevented with constant ventilation using an adequate ventilation air volume.
(4) Humidification was possible by adding a simple humidifying unit to the Lossnay unit.
3. Hospitals
3.1 System Design Challenges
Ventilating a hospitals required adequate exhaust air from the generation site and ensuring a supply of ample fresh outdoor air.
An appropriate system was an independent ventilation system with forced simultaneous air intake/exhaust.
The fan coil and package air conditioning were according to material and place, and the air conditioned room was ventilated
with ceiling-embedded-type Lossnay units. The toilet and kitchenette, etc., were ventilated with a straight centrifugal fan.

3.2 System Requirements
(1) Prevented in-hospital disease transmission.
(Meeting needs for operating rooms, diagnosis rooms, waiting rooms and patient rooms were required.)
(2) Adequate ventilation for places where odors were generated
(Preventing odors generated from toilets from infiltrating into other rooms was required.)
(3) Blocking external sound
(Blocking sound from outside of the building and from adjacent rooms and hallway was required.)
(4) Assuring adequate humidity
