2.3 Variable speed advantages
The variable speed scroll is a key component in the variable capacity system. A variable capacity
system will use less electrical energy by minimizing on-off cyclical losses, maximizing heat
exchanger efficiency by operating at part load during a majority of the total operating hours, and by
operating with reduced airflow rates and blower power.
The variable speed scroll and drive are suitable for a variety of "best-in-class" applications. Both may
be used in other types of applications provided that the envelope and other operating restrictions are
met. The primary benefit of this product is to substantially reduce electrical energy consumption and
associated expenses.
Additionally, a variable speed scroll offers the capability of controlling space and domestic hot water
temperature to ranges exceeding simple on-off control, improving overall comfort levels inside the
building. The onboard electronics embedded in the drive greatly reduce the possibility of operation
outside the designed parameters which in turn increases overall system reliability.
