APPLICATION DATA

UNIT SELECTION

When selecting a variable speed system match the system capacity

range to the anticipated load range. Since a variable speed system

can accommodate a wide range of loads it is important to

understand the percentage of time that the system will be required

to run at the both the maximum and the minimum load points. This

differential is most evident when a residential application is

compared with a commercial application.

Generally there will be more load diversification in the residential

application (shifting from low load to high load).

The commercial application will tend to be more steady during the

normal day time hours, and will go to low load levels after normal

business hours. If it is anticipated that the system will be required

to run at the maximum load point for the majority of the time, the

next larger system capacity should be selected.

The tables below are guidelines for selecting the proper size for the

application.
