A fully optimized design can realize a
number of benefits:
»
Cheaper equipment & installations costs
»
Less outdoor unit footprint
»
A greater energy efficient system
»
Far better control of room temperature
»
A significant increase in the probability of
winning a project
Key Points for Selection
System Diversity vs Connection Ratio
Unit Type
Selection Scope
Selection Approach
PEAK Load
Each Indoor unit should be sized
to deliver the PEAK load (total
and/or sensible) of the area it
is to serve, at the entering air
design conditions, determined
by the building load calculations
BLOCK Load
Outdoor units should be
selected to meet the BLOCK
Cooling & Heating capacities
(The maximum simultaneous
load demand of all attached
indoor units at a given time of
day) determined by the same
LOAD Calculations
Optimizing VRV System Selection
»
The most successful users of VRV equipment understand the
importance of a fully optimized design
»
A key factor that ensures optimized VRV equipment selection
is to understand the correlation between SYSTEM DIVERSITY
& CONNECTION RATIO
Peak Loads & Block Loads
The first step to optimization is to understand the different load
demands of the equipment to be selected:
