General Information
2. Points to Bear in Mind at the System Design
2.1
Points Relating to the Performance of the Air
Conditioning Units
A number of points need to be borne in mind at the system design stage in order to ensure the mechanical
efficiency of the air conditioning units.
1. Path of refrigerant piping between outdoor and indoor units, height difference and pipe length.
!
Path of refrigerant piping should be determined such that length of piping is kept to a minimum.
!
Piping should be kept within permissible limits in terms of length and height difference.
2. Positioning of outdoor unit
!
Position such that maintenance and repairs can be carried out. (leave room for servicing)
!
Avoid reduction of airflow and short circuiting
!
Avoid reduction of airflow and short circuiting
3. Positioning of indoor unit
!
Position such that maintenance and repairs can be carried out. (inspection port positions and size
check)
!
Avoid short circuiting
!
Ensure sufficient drain pipe gradient (need for drain-up kit etc.)
!
In the case of a ceiling mounted type make sure ceiling depth is sufficient (need for high performance
filter, etc.)
