Public Halls (Combination Facilities Such As Day-Care Centres) - Mitsubishi Electric Lossnay LGH-100RX3-CAN Technical Manual

CHAPTER 6 Examples of Lossnay Applications

6. Public Halls (combination facilities such as day-care centres)

6.1 System plan points
Air conditioning and ventilation facilities for buildings located near airports and military bases, etc., that require soundproofing,
have conventionally been of the centralised method. However, independent dispersed air conditioning and ventilation has
been demanded due to the need for operation in zones, as well as for energy conservation purposes. This system is a plan for
these types of buildings.
Setting outline
Building form : Above ground 2, Total floor space: 385 m
Application : GF Study rooms (2 rooms), office, day-care room, lounge
1F . . . . . Meeting room
Air conditioning : GF Air-cooling heat pump chiller and fan coil unit
1F . . . . . Air-cooling heat pump package air conditioner
Ventilation : Ceiling embedded Lossnay
6.2 Conventional system and topics
(1) Conventional systems have used centralised methods with air handling units, and air conditioning and ventilation were
generally performed together.
(2) Topics
1) Special knowledge is required for operation, and there are problems in response to the users' needs.
2) When the centralised method is used, the air even in rooms that are not being used is conditioned, increasing
running costs unnecessarily.
3) Machine room space is necessary.
4) Duct space is necessary.
6.3 Plan details
(1) Air conditioning facilities
1) Small rooms : Air-cooling heat pump chiller and fan coil unit combination
2) Meeting rooms : Single duct method with air-cooling heat pump package air conditioner
(2) Ventilation facilities
1) A ceiling embedded-type Lossnay is used in each room, and a silence chamber, silence-type supply/return grille,
silence duct, etc. is incorporated on the outer wall to increase the total soundproofing effect.
