Examples of Lossnay Applications
Reception
3.3 Details
(1) Air Conditioning
•
Centralized heat-source control using a fan coil for the
general system allowed efficient operation timer control and
energy conservation.
•
A 24-hour system using a package air conditioner for
special rooms (surgery theater, nurse station, special
patient rooms, waiting room) was the most practical.
(2) Ventilation
•
Hallway
Independent system using centralized control with large air
volume Lossnay units, or independent system with ceiling
suspended-type Lossnay units.
•
Surgery theater
Combination of larger air volume Lossnay and package air-
conditioner with HEPA filter on room supply air outlet.
•
Diagnosis rooms and examination room
Patient rooms
Nurse stations
Independent ventilation for each room using ceiling
suspended/embedded-type Lossnay.
•
Integral system with optional humidifier for required
rooms.
•
Positive/negative pressure adjustment, etc., was possible
by setting main unit selection switch to extra-high mode
(smaller air volume models) according to the room.
•
Toilet/kitchenette
Straight centrifugal fan or duct ventilation fan
•
Storage/linen closet
Positive pressure ventilation fan or duct ventilation fan.
The outdoor air was supplied from the hallway ceiling with
the straight centrifugal fan, and was distributed near the
indoor unit of air conditioner after the air flow was reduced.
•
Kitchen
Exhaust with negative pressure ventilation fan or straight
centrifugal fan. Outdoor air was supplied with the straight
centrifugal fan.
•
Machine room
Exhaust with positive pressure ventilation fan.
3.4 Outcome
(1) The following outcomes were possible by independently ventilating the air-conditioned rooms with Lossnay units:
•
Disease transmission could be prevented by shielding the air between rooms.
•
Lossnay Core’s sound reducing properties reduced outside sound.
•
Because outdoor air did not need to be taken in from the hallway, doors could be sealed, shutting out sounds from the
hallway.
•
Humidification was possible by adding a humidifier.
(2) By exhausting the toilet, etc., and supplying outdoor air to the hallway:
•
Odors infiltrating into other rooms were prevented.
