Optimize Chillers with an Automatic Entering Condenser Water Temperature Reset Strategy

A chilled water plant’s annual operating cost is a major contributor to a facility budget. Typical chilled water plants consist of multiple chillers, cooling towers, chilled water pumps, condenser water pumps, plate heat exchangers and water treatment equipment. The chilled water is generated in the central plant and then transported through a piping network to cooling coils (air handlers) or to point of end-use in processes. Facility directors and energy managers are always chasing multiple goals – satisfying all the customers, maintaining a high level of reliability and minimizing energy spends with varying demand and weather. Therefore, many modern plants employ a good chiller optimization package such as Hudson Technologies’ SMARTenergy OPS® in conjunction with Building Automation Systems (BAS) to optimize the chiller plants.   Chiller Plant Efficiency Driven by Cooling Tower Management In a water-cooled chiller plant, co […]

PROPER REFRIGERATION TEMPERATURES AND WHY THEY MATTER

Commercial refrigeration units are a business investment. Since these units cost thousands of dollars, keeping them in working order is a necessity to avoid costly and time-consuming replacements and new installations. In order to keep a commercial refrigerator running as it should, it’s important to implement regular maintenance. Many business owners can perform some of these tasks themselves, while others are more complicated and require the help of a professional. In order to ensure a unit works as it should, it should be installed correctly and placed in such a way that any fans aren’t covered. Improper installation or placement can lead to failure, even with regular maintenance. At least every three months, the unit should be visually inspected to see if there are any visible issues. Are there puddles of water inside or around the unit? Is there a buildup of ice, or is a fan not spinning properly? If so, any of these issues will ne […]

Water to Ice: How an Ice Machine Works

There was a time when a chilled drink and refrigerated food storage were the domain of cold climates and winter days. Since Boston businessman Frederick Tudor decided in 1806 to sell blocks of ice pulled from the surfaces of New England ponds, large parts of the world have come to rely on ice as a year-round staple and dining requirement. Over a couple of centuries and some years since then, we’ve moved from fickle, hard-to-store, and sometimes dirty natural ice to cubes, flakes, and nuggets produced by ice machines. Though the process is a little less organic now, at its heart it’s no less simple than combining cold and water. Still, some steps in making ice are still a mystery even to those who have been dealing with a commercial ice maker for years. So, let’s look inside the machinery and inside the process. The Refrigeration System in a Commercial Ice Machine The heart of every commercial ice machine is a refrigeration system simila […]
