What exactly do ‘subcooling’ and ‘superheat’ mean – and why are they so important for the efficiency and reliable operation of a refrigeration system? In this episode of AHT EXPERT TALK, AHT explain both terms in simple terms and show how they affect the performance, energy consumption and operational reliability of commercial refrigeration systems.


They cover:

  • What superheat and subcooling actually mean

  • Where they occur in the refrigeration cycle

  • How they are measured and calculated

  • Why the correct values matter for system efficiency

  • What happens when superheat or subcooling is too high or too low

  • How these parameters can help identify refrigeration system problems

  • Their impact on compressor operation, energy consumption and system reliability


Whether you work in food retail, refrigeration planning, installation or service, this episode will help you better understand two of the most important parameters used to evaluate refrigeration system performance.
