Medium Size Office Building - Mitsubishi Electric Lossnay LGH-15RX3 Technical Manual

(3) Humidification
If the load fluctuation of the required humidification amount is proportional to the ventilation volume, it is ideal to combine the
humidifier installation with the ventilation system. For this application, the humidifier is installed on with the air supply side of
the Lossnay.
(4) Conformation to Building Laws
The most important consideration here is humidification and dust removal; in these terms, it is recommended that a humidifier
is added to the air conditioning system for the office system to allow adequate humidification.
Installation of a filter on each air circulation system in the room is effective for dust removal, but if the outdoor air inlet is near
the dust source, such as a road, a filter should also be installed on the ventilation system.
1.4 Effect
(1) Air conditioning and ventilation needs can be met on an individual basis.
(2) Operation is possible with a 24-hour system.
(3) Operation is simple with the switches being in the room. (A controller is not required.)
(4) Floor space is saved and thus the floor can be used to the maximum.
(5) Energy is conserved with the independent heat recovery.
(6) Fresh air air-conditioning is possible with the independent system.

2.1 System plan point
In recent building air conditioning systems, demands for a consistent rationalization from design through operation and control
aspects are being made to meet diversified building needs.
In the entire air conditioning facility, either the cooling/heating source equipment or specific air conditioning equipment is
considered as being only one element. Thus, it is important to design this element so that it covers the user's needs while
providing total amenity.
This air conditioning system plan is for a so-called company building that is largely divided into the general office section
(hereinafter referred to as general floors) and special room sections including board rooms and conference rooms (hereinafter
referred to as special floors). Furthermore, Building Management Laws are applied to the building due to the scale.
