CHAPTER 6 G Examples of Lossnay Applications
5.4 Effect
(1) The following is possible by independently ventilating the air-conditioned rooms with the Lossnay:
G
Transmission of diseases can be prevented by shielding the air between rooms.
G
Infiltration of outside noise can be prevented with the Lossnay Core's soundproof properties.
G
As outdoor air does not need to be taken in from the hallway, the door can be sealed, shutting out hallway noise.
G
Humidification is possible by adding a humidifier.
(2) By exhausting the toilet, etc., and supplying outdoor air to the hallway:
G
Flowing of odors to other rooms can be prevented.

6. Schools

6.1 System plan points
A comfortable environment in classrooms is necessary to improve the children and students' desire to study.
Schools near airports, railroads and highways have sealed structures to soundproof the building, and thus air conditioning and
ventilation facilities are required. This is also true for schools in polluted areas such as industrial districts.
At university facilities which have a centralised design to efficiently use land and to improve the building functions, the room
environment must also be maintained with air conditioning.
6.2 Current system details and problem points
(1) Mainly single duct methods, fan coil unit methods, or package methods are used for cooling/heating, but the diffusion rate
is still low, and water-based heaters are still the main source of heating.
(2) The single duct method is difficult to control according to the usage state, and there are problems in running costs.
(3) Rooms are often ventilated by opening the windows or using a ventilation gallery, where although this provides ample
ventilation volume it may create a problem of infiltration of outside noise.
