Energy Efficient and Sustainable Refrigeration Systems

Energy Efficient and Sustainable Refrigeration Systems

This course provides guidance to refrigeration system design teams about selecting energy-efficient refrigeration systems that use low-global warming potential (GWP) refrigerants. It is based on work done by USDOE’s Commercial Building Partnerships (CBP) which is a public/private, cost-shared initiative that demonstrated cost-effective, replicable ways to achieve dramatic energy savings in commercial buildings. CBP aimed to reduce energy use by 50% in new construction and 30% in existing buildings compared with minimum code requirements or pre-retrofit energy use. In recent years, supermarket refrigeration systems have been trending toward using smaller refrigerant charges and applying synthetic refrigerants with lower GWP or natural refrigerants with negligible GWP.

This course covers recent history and describes the trends that have focused attention on low-GWP refrigeration systems, presents the six alternative refrigeration system configurations, and describes the physical properties of NH3, CO2, and propane and their implications for system design. It includes safety and compliance considerations, introduces simple financial evaluation techniques, and encompasses high-level considerations for building owners for regulatory compliance, cost control, challenges to adoption of alternative systems, and noneconomic considerations such as corporate image.

Once you complete your course review, you need to take a multiple-choice quiz consisting of thirty (30) questions to earn 6 PDH credits.

Learning Objectives

This course is intended to provide you with the following specific knowledge and skills:

  • Evaluate the performance of multiple alternative refrigeration system designs for different climates across the United States
  • Be knowledgeable of safety and compliance considerations that must be taken into account when working with alternative refrigerants
  • Estimate energy savings and environmental impacts of various refrigerants and configurations
