In an effort to improve operating efficiencies on water chillers, a patent has been issued on a water chiller economizer system by Martin P. King, inventor and president of leading chiller manufacturer Legacy Chiller Systems.
As a cost effective way to save energy, the patented system (Patent 8,418,487) integrates with existing chiller technology. The system allows for chilling a process fluid that can be transported to a process load to remove thermal energy from the process load. The process-fluid chiller system includes a storage tank where the process fluid can be stored, as well as a refrigeration system that can be selectively activated to chill the process fluid.
“With the way the industry is changing, I thought it was really important to find an energy efficient solution,” said King. “We found during our research that application of wet-side economizers on the process side wasn’t really considered by U.S. manufacturers due to the operational challenges in this area.”
The patent comes as a result of over eight years of hard work. In 2005, Legacy Chiller Systems commissioned a feasibility study on the application of wet-side economizers for mission critical applications. The first tests completed in 2006 produced a 10%-15% kilowatt hour (KWH) reductions. By 2007, KWH savings had improved to 35%-60% through the use of a new economizer controller and specialized software developed by the Legacy Chiller team.
Chillers have been used for HVAC and process cooling systems for decades. The patented design by King opens the door for several key markets, including data centers, healthcare and medical imaging (MRIs, CT, PET) as well as laser and semi-conductor manufacturing. Economizer technology offers the highest return on investment when outdoor temperatures run 5-10 degrees cooler than process fluid design temperatures.
