While the chiller is typically the most visible part of the system, other key components include chilled and condenser water pumps, cooling towers, heat exchangers, etc. This article focuses on maintaining these components “beyond the flange,” which are found in most typical building comfort cooling applications.
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) is moving forward with an ambitious project to identify low global warming potential (GWP) refrigerants. What does that mean?
Providing a 12- to 15-dBa sound reduction, the Whisper Quiet Fan for the PT2 cooling tower has CTI certified thermal capacity, and is ASHRAE 90.1 compliant, says the company. The fan itself is a chemical resistant, durable, high solidity, single piece, molded fan made out of fiberglass reinforced polyester.
An environmentally friendly product, the ScaleBlaster eliminates formation of limescale deposits in pipes, cooling towers, boilers, and other applications. The equipment is comprised of a computerized control box and a signal cable that is wrapped around the outside of the pipe.
The DP700 is a compact brazed plate heat exchanger for chillers. According to the manufacturer, it is a compact brazed plate heat exchanger that outperforms traditional evaporators for chillers. The true-dual brazed plate heat exchanger is designed for R-410A chillers, with a cooling capacity range up to 700 kW.
New technology in the HVAC industry stretches past equipment breakthroughs and component enhancements. Ancillary software and communication elements are often keys to making advanced heating and cooling solutions run correctly.
When evaporation occurs in a cooling tower, only the water evaporates; it exits the cooling tower as water vapor, but leaves the minerals behind to concentrate in the cooling tower’s water system.
As part of a renovation plan, Florida State College at Jacksonville researched a number of upgrade scenarios for its chiller plant. Initial recommendations for a conventional chiller failed to meet budget and energy-savings requirements. During the re-evaluation process, the college team visited Flagler College to see a chiller actually using the compressors.
