In this informative session from the 5th Annual HVAC/R Training Symposium, Matthew Taylor draws from his 25 years of experience in the supermarket world to provide an Introduction to Market Refrigeration for HVAC Techs.
Matthew covers the key differences between residential/commercial air conditioning systems and the parallel rack refrigeration systems found in supermarkets. He explains how the core refrigeration cycle concepts are the same, but the physical setup, components, and control strategies differ in market refrigeration.
Some of the topics covered include:
Major components like compressor racks, condensers, and evaporator cases
Control systems and sensors for precise temperature/pressure regulation
Maintaining different evaporator temperatures for product zones (freezers, coolers, etc.)
Defrosting strategies for evaporator coils running below freezing
Reclaim systems that recycle compressor heat for hot water or dehumidification
Split condensers and fan staging for low ambient operation
Whether you're an HVAC tech looking to understand grocery store refrigeration better or just interested in learning about this specialized area, Matthew's engaging presentation provides a clear overview. The session allows for participant questions throughout.
