Seminar 52 -- Systems and Components Performance and Efficiency with Low-GWP and Natural Refrigerants, Part 2 ✓ Most Recent

This product is a PDF that contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

The properties of the new low-GWP and natural refrigerants, such as HFO, R-32, R-152a, ammonia, hydrocarbons, CO2, etc. have an impact on the performance and efficiency of the refrigeration and air-conditioning systems and their components. A special attention in this session is dedicated to the design, operation, and servicing equipment with flammable refrigerants, such as hydrocarbons and ammonia. The issues and challenges are illustrated in the example of a household refrigerator/freezer with R600a for use on the U.S. market. Two presentations provide a comprehensive analysis of efficiency and operational aspects of equipment with ammonia.
