Efficiency Gain at FUSD


Courtesy of Power Knot LLC

Power Knot treated a four ton (14 kW) roof-top packaged air conditioning unit with its Synthetic Refrigerant Additive (SRA) at the Mission Valley Elementary School in Fremont, California. After treatment, the efficiency of the unit increased by over 16%, resulting in savings in electricity cost and increasing the air conditioning cooling capacity for 32 students in their classroom. However, the room did not get ice cold! [In the past, Power Knot referred to the product as the Synthetic Refrigerant Catalyst; the term Additive is now preferred.]

About the Mission Valley Elementary School
Mission Valley Elementary, one of 28 elementary schools within the Fremont Unified School District (FUSD) is located on the southeast side of San Francisco Bay in the beautiful city of Fremont which lies between San Jose and Oakland in Alameda County.

The school’s population is over 750 students with class sizes of 1:20 in grades K-3 and 1:30 in grades 4-6.

The school consists of a rich ethnic diversity of students.

The Problem
With a shrinking budget in the fiscal year 2010, the Fremont Unified School District is exploring various ways to reduce expenditures. Energy cost is one of the major expenses for the 48 schools in the Fremont district.

Attendance in the Fremont schools has been increasing for the past few years. This has driven up the cost for operating the schools from salaries and classroom supplies all the way to facilities and maintenance. The energy cost for classroom electricity and heating has also increased significantly over the years. FUSD is interested in deploying new energy saving solutions to help them reduce their energy cost.

The Solution
The SRA from Power Knot improves energy efficiency of a cooling system and can saves customer’s money. It is injected into the refrigeration circuit of the cooling system and improves heat transfer by eliminating the “oil fouling” that occurs in a cooling system.

Power Knot guarantees a minimum of 10% gain in efficiency after the proper application of the SRA. In the case of FUSD, this can translate to greater cooling in the classroom with the same amount or a decrease in electricity usage.
