This article will make plants aware of the energy and water use differential between CHW systems providing chilled water in a 45-60°F (7-16°C) range, and process cooling solutions at 70°F up to 120°F (21 to 49°C). The article will examine cooling resource evaluation criteria and supply water temperature specifications, then describe and compare process cooling options.

Heat pumps have found growing popularity as a high-efficiency solution for cooling and heating. With greater public awareness and organizational emphasis on sustainability, these systems are a viable upgrade to a wide range of processes, from residential climate control to industrial heating and cooling applications. The flexible functionality of heat pumps – namely their ability to reverse the traditional vapor-compression cycle – offers them significant advantages over refrigerant and combustion-based systems.

The customers wanted to be able to monitor their system from a control room. They wanted to be able to see the overall view of how the system was running. The bigger thing on the backend – especially for us from an engineering perspective – was being able to do better troubleshooting and helping them without the need to be onsite.

Dry fluid coolers use ambient air to reject heat from hot process fluids running through the unit’s closed-circuit coil heat exchanger. Dry coolers have either flat or V-shaped configurations. Hybrid fluid coolers combine closed-loop dry cooling with evaporative cooling for an efficient design that uses less water. Hybrids can be run in dry mode when the temperature set point can be met by dry cooling alone. Adiabatic coolers are a type of dry cooler that use some water to pre-cool the ambient air used to reject heat from the process fluid. 

Day 2 of the Best Practices 2024 EXPO & Conference began with high-level learning sessions. For some attendees, the most important session of the conference was the expert panel on designing compressed air systems compliant with the ASHRAE 90.1 standard, which now includes compressed air systems.

Day 1 of the Best Practices 2024 EXPO & Conference saw the annual event’s highest attendance yet, with a record number of manufacturing plants, distributors and engineering firms. The event started yesterday, October 29th, at the Cobb Galleria in Atlanta, GA, and runs until Thursday.

In this article, the independent third-party product certification body Eurovent Certification explains how to aim for excellence and safeguard against reliability risks by using products with proven performance.

In August 2024, Johnson Controls hosted a showcase at its Johnson Controls Advanced Development and Engineering Center (JADEC) in New Freedom, PA, to share testing and engineering capabilities of its applied HVAC equipment for data centers and semiconductor manufacturers.

Machine cooling high temperature problems are unfortunately all-too common in industrial plants. While the initial suspect is always the heat exchanger, there are several other factors that can be the underlying cause. Important steps can be taken to minimize the potential for heat exchanger fouling, but when problems do occur, careful examination of the machine and the system can help identify the problem efficiently and with minimal wasted effort.

Johnson Controls’ most recent decarbonization project has gone right to the heart of its 2040 net-zero commitment – working with its own Norman, Oklahoma, manufacturing facility on a chilled water plant and compressed air system upgrade that is projected to nearly halve its greenhouse gas emissions.
