Refrigeration - A better controller
This will PROBABLY be the last post on refrigeration. At least I hope so. The system is running perfectly. Here is what’s new: First some back-story. While we have been very happy with the refrigeration set up on BlueJ for the last seven years, there’s one aspect of performance that has always been less than I would want. And that’s the controller. Speaking of back-story, if you want to read about BlueJ refrigeration from the beginning, start HERE . The Isotherm ICEC controller that came with our system is marketed as an energy saver. It also slow-starts the compressor, and is reported to have a way to bank cold in the fridge when there is excess DC power available. Sadly with the exception of the slow-start, I’m not sure any of those claims are true, and it has difficulty maintaining correct temperature when the ambient air is very warm. So not perfectly happy. Most of this fault comes in the design. It is essentially an analog device trying to do the job of a digital controlle
