Abstract: This paper concentrates on a control method for the prediction of variable speed pumps working in parallel to keep them running close to the best efficiency point (BEP). First, theoretical ...

Using variable speed drives on pumps reduces parasitic energy loss, enables proper maintenance and lowers capital costs. This article examines a method for determining the optimal number and speed of ...

In an industry evolving alongside consumer concerns over rising energy costs, impact on the environment, and, of course, stricter regulations handed down by the government, new technologies are ...

The Department of Energy (DOE) now requires new pool pump motors and replacement dedicated purpose pool pumps (DPPP) for most in-ground pools to be variable speed because they are more energy-… ...

Government incentives and tax credits have made the switch to heat pumps more affordable for consumers who want to lower energy costs and improve efficiency in their homes. As the “heart of the HVAC ...
