The RSES Member Webinar series continues with an exploration of superheat and subcooling.

The webinar will start out with the basics of the three forms of refrigerant in a closed loop system. The term saturated will be defined as it relates to the refrigeration process. The terms subcooling and superheat will be defined as it relates to the refrigeration cycle, as well as why both are needed and how they protect the compressor.

Additional topics in this webinar include: how to use the P-T More...chart to determine the correct subcooling and superheat in a system; how to determine if there is enough, too little or too much superheat in a system; and how subcooling can affect the superheat of the system and what can be done to correct its balance.

The webinar will also cover how to determine if there are non-condensables in the systems when troubleshooting. There will be discussion of the limitation of the standard P-T chart and analog gauge sets and using digital gauges and temperature probes.
