Cooling Towers
This article will explore why tanks are used in cooling systems, why they might not be used in cooling systems, and finally considerations to be evaluated in determining if tanks are needed in any particular central plant cooling system. Part 2 will review specific application details for using tanks and also for tankless systems and system conversions.
This article will explore the Cooling Technologies Institute (CTI) Standard 201 (STD-201) Thermal Certification This article will explore the Cooling Technology Institute (CTI) Standard 201 (STD-201) Thermal Certification Program, share perspective from leading cooling tower manufacturers, and cover other existing and evolving CTI test codes, standards and certifications. This article will also emphasize the investment and bandwidth contributed to CTI by cooling tower manufacturers for the benefit of the industry and its end users.

An Illinois food service products manufacturer now saves nearly 60% of their base annual cooling energy costs through improvements made in three phases over several years. The plant, which has a 1200 ton chilled water plant, implemented upgrades including pump and tower fan VFDs and enhanced function controls, free cooling, and chiller compressor drive retrofits. The revisions built through successive phases to capture further benefits from more complete utilization of the preceding steps’ capabilities.

With efficient heat exchange an important requirement in the design of an HVAC system, the type of cooling tower you specify to support your project’s unique cooling goals requires careful consideration. After determining the process parameters required for your application – tonnage, range, and approach – cooling tower capabilities can be analyzed.

For the Production Support team at the expansive Quad printing plant in Sussex, Wis., there isn’t one way to manage the operation’s complex and elaborate process cooling system. Rather, the formula for success involves a three-pronged approach that includes carefully measuring and monitoring system performance, diligently and proactively maintaining equipment to ensure peak efficiencies, and investing in updated equipment based on sound decision making.

rPlanet Earth is a rarity in the plastics recycling and manufacturing industry. After all, its operation in Vernon, California, is the world’s only vertically integrated facility able to convert polyethylene terephthalate (PET) packaging waste into recycled PET (rPET) packaging for food and beverage industries. Yet, rPlanet Earth is much like any other plastics company in one key aspect: it must maintain production efficiencies to meet growing demand for its high-quality products.

“Evaporative cooling capacity for the district system is provided by a six-cell, open-loop cooling tower capable of 6,000 tons,” said Reid Olsen, USU Central Energy Plant Manager, who has been at the university for 26 years. “This tower serves the condensers of the water-cooled chillers at the heart of the district cooling system. There are four chillers in all, two of which are rated for 1,800 tons each, and the other two are 900 tons apiece. The cooling towers reject heat from the condenser water loop via evaporative cooling, allowing the chillers to supply chilled water to the campus cooling loop.”

When a cooling tower supporting the HVAC system at NYC Health + Hospitals/Lincoln was nearing its expected end of life, the management of the 362-bed hospital in the South Bronx saw an opportunity. The year before, the neighboring community had experienced outbreaks of Legionnaires’ disease, and even though the hospital’s cooling towers played no role in those outbreaks, the chance to increase protections against possible future exposures of the bacteria that cause the disease was an important consideration.
