Examples of Lossnay Applications
Lossnay ventilation systems are proposed for eight types of applications in this chapter. These systems are planned for
Japanese use, and actual systems will differ according to each country. These should be used only as reference.
1. Large Office Building
1.1 System plan points
Conventional central systems in large buildings, run in floor and building ducts, have generally been preferred to individual
room units. Thus, air conditioning and ventilation after working hours was not possible.
In this plan, an independent dispersed ventilation method has been applied to resolve this problem. Such a system’s main
advantage is that it allows 24-hour operation.
A package-type air conditioning unit is installed in the ceiling, and ventilation is performed with the ceiling-embedded-type
Lossnay. Ventilation in the toilet, kitchenette and lift halls, etc., is performed with a straight centrifugal fan.

: Ceiling embedded-type Lossnay, straight centrifugal fan
1.2 Current topics
(1)
Operation system that answers individual needs is required.
●
Free independent operation system
●
Simple control
(2)
Effective use of floor space
(elimination of machine room)
(3)
Application to Building Management Laws
●
Effective humidification
●
Elimination of indoor dust
(4)
Energy conservation
1.3 Proposed details
(1) Air conditioning
●
In general offices, the duct method will be applied with
several ceiling-embedded multiple cooling heat pump
packages in each zone to allow total zone operation.
●
Board rooms, conference rooms and salons will be air
conditioned with a ceiling embedded-type or cassette-type
multiple cooling heat pump package in each room.
Installation state of office system air conditioning system
– The air supplied from the Lossnay is introduced into
the intake side of the air conditioner, and the room stale
air is directly removed from the inside of the ceiling.
