5.4 Plan details
(1) To pursue comfort, save energy and space, an air
conditioning and ventilation system using a ceiling
embedded-type fan coil unit and ceiling embedded-type
Lossnay was applied.
(2) Automatic operation using a weekly program timer was
applied, energising when the general classrooms and special
classrooms are to be used.
(3) By using a ventilation system with a total heat recovery unit,
energy is saved and soundproofing is realised.
5.5 Conditions for air-conditioning in
schools
(1) Zoning according to application must be possible.
(2) Response to load fluctuations must be swift.
(3) Ventilation properties must be good.
(4) The system must be safe and rigid.
(5) Expansion of the facility must be easy.
(6) Installation on existing buildings must be possible.
(7) Installation and maintenance cost must be low.
5.6 System trends
(1) It is believed that environmental needs at schools will continue to progress towards high quality, and various factors such
as temperature/humidity, noise, natural lighting, and colour must be considered at the design stages. Important topics are
air conditioning, ventilation and soundproofing.
(2) Independent heating using a centralised control method is mainly applied when the air conditioner is for heating only. For
cooling/heating, a combination of a fan coil method and package-type is the main method used.
(3) Highly accurate Class 1 ventilation is applied for the ventilation method, and the total heat recovery unit is mainly used in
consideration of the energy saved during air conditioning and the high soundproofing properties.
