4.3 Plan proposals
(1) Air conditioning
Centralised heat source control using a fan coil for the
general system allows efficient operating time control and
energy conservation.
24-hour system using a package air conditioner for special
rooms (surgery theatre, nurse station, special patient
rooms, waiting room) is the most practical.
(2) Ventilation
Hall system
Independent system using centralised control with LP
Lossnay or independent system with installation of ceiling
suspended-type Lossnay
Surgery theatre
Combination use of LP 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 possible for
required rooms.
Positive/negative pressure adjustment, etc., is possible
by setting main unit selection switch to extra-high notch
(25R, 50R 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 is supplied from the hallway ceiling with
