Problems solved by technology

A difficulty with some existing systems is that, at part-load, the pumping system may be susceptible to instability, poor occupant comfort and energy and economic wastage.
The traditional selection of a pump or pumps may resul...

Embodiment Construction

[0025]Example embodiments generally relate to circulating devices such as pumps, boosters and fans, and related systems.

[0026]In accordance with an example embodiment, there is provided a method for prioritizing a plurality of variable speed devices. The method includes: determining, for a first variable speed device, a cost dependent on an operating cost of the first variable speed device operating at part loads for a specified period of time, determining, for a second variable speed device, a second cost dependent on an operating cost of the second variable speed device operating at part loads for the specified period of time, and displaying on a graphical interface screen a listing of the first variable speed device and the second variable speed device in a priority order based on the cost and the second cost.

[0027]In accordance with another example embodiment, there is provided a computer system, comprising: a controller and memory for storing information of a plurality of varia...

Abstract

A method, computer system, and computer readable medium for prioritizing a plurality of variable speed devices. The method includes: determining, for a first variable speed device, a cost dependent on an operating cost of the first variable speed device operating at part loads for a specified period of time, determining, for a second variable speed device, a second cost dependent on an operating cost of the second variable speed device operating at part loads for the specified period of time, and displaying on a graphical interface screen a listing of the first variable speed device and the second variable speed device in a priority order based on the cost and the second cost.

Description

CROSS-REFERENCE[0001]This application claims the benefit of priority to U.S. Patent Application No. 61 / 591,234, filed Jan. 26, 2012, the contents of which are herein incorporated by reference.TECHNICAL FIELD[0002]Some example embodiments relate to the field of circulating devices such as pumps, boosters and fans, and related systems.BACKGROUND[0003]In some conventional systems, manufacturer specifications for equipment are published with maximum load ratings. As an example, for fixed speed HVAC (heating, ventilation, and air conditioning) pump systems, performance criteria may be based on a narrow band of conditions, optimizing for occupant use during maximum load, which often meant sacrificing operating efficiency during part-load conditions.[0004]Prior to variable speed drives, some conventional industry practices meant designing heating, cooling and plumbing system performance around a single point that represented the most extreme conditions or loads that a building might experi...
