Hospitals - Mitsubishi Electric Lossnay LGH-15RX3 Technical Manual

CHAPTER 6 G Examples of Lossnay Applications
4.4 Effect
(1) Accurate ventilation is possible with Class 1 ventilation (forced simultaneous air intake/exhaust) using the Lossnay.
(2) Outdoor air supply to the toilet and kitchenette is possible with the Lossnay, and accurate ventilation is possible even in
highly sealed buildings.
(3) Flow of odors can be prevented with constant ventilation using an adequate ventilation volume.
(4) Humidification is possible by adding a simple humidifying unit to the Lossnay.

5. Hospitals

5.1 System plan points
The principle of ventilation in hospitals requires adequate exhausting from the generation site and ensuring a supply of ample
fresh air. An appropriate system would be an independent ventilation system with Class 1 ventilation (forced simultaneous air
intake/exhaust).
The fan coil and package air conditioning are used according to material and place, and the air conditioned room is ventilated
with the ceiling embedded-type Lossnay. The toilet and kitchenette, etc., are ventilated with a straight centrifugal fan.

5.2 Current topics
(1) Prevention of in-hospital transmission of diseases
(Measures meeting needs for operating rooms, diagnosis rooms, waiting rooms and patient rooms are required.)
(2) Adequate ventilation for places where odors are generated
(Measures to prevent odors from toilets from flowing to other rooms are required.)
(3) Shielding of external noise
(Shielding of noise from outside of building and noise from adjacent rooms and hallway is required.)
(4) Assurance of adequate humidity
(5) Energy conservation
