Proper maintenance and operation of RAC plants remain significant challenges due to increasingly complex systems, evolving technologies, and the introduction of new refrigerants requiring specialized knowledge and handling. The Assessing RAC Plant Sustainability tools provide practical support in addressing these challenges, a press release from ASHRAE said.

“These tools provide practical guidance that connects design intent with operational outcomes,” said ASHRAE president Bill McQuade. “By helping RAC professionals assess and improve sustainability across key performance areas, we’re empowering the industry to make data-informed decisions that benefit the environment, their workforce, and their bottom line.”

Originally designed for field technicians, the tools can also be used by plant managers, equipment suppliers, and consulting engineers. According to the press release:

• Plant managers can assess current operations across eight key dimensions, including refrigerant emissions, energy consumption, and preventive maintenance, using the tools to make informed sustainability improvements and reduce operating costs.

• Suppliers can train customers in preventive maintenance strategies that increase equipment life, efficiency, and compliance, while supporting life-cycle cost savings and performance accountability.

• Engineers can incorporate the checklists into training documentation, strengthening the connection between design objectives and real-world operations, while closing knowledge gaps among stakeholders.

The guidance also includes recommendations for energy-efficient operation, life-cycle investment considerations, and key performance indicators to help determine when equipment upgrades are warranted, the press release said.
