We Tried Talking About Subcoolers, And Nozzles, Vermont Is Beautiful Episode 533Storms, CO2 Chaos & Subcooler Shenanigans | Advanced Refrigeration PodcastHosts Brett Wetzel and Kevin Compass open the Advanced Refrigeration Podcast with stories from a week derailed by severe storms, power outages, and traffic caused by downed lines. Brett describes a startup nightmare at a new CO2 store: a Danfoss controller pressure-reading issue drives a rack into high-head cycling, a backup condensing unit is disabled by a tripped breaker traced to an earwig in a contactor, and the site loses charge and power while relief-valve issues persist and generator startup is delayed. They then discuss building a transcritical water-cooled condenser skid for a high-rise and criticize building condenser-water BTU billing in winter when grocery racks effectively replace boilers. The conversation shifts to basic refrigeration, focusing on mechanical subcooling benefits, TXV sizing realities, nozzle color codes, and common control mistakes involving sensors, gauge vs absolute settings, wiring errors, and strategies to prevent floodback.
