Some advice on refrigeration requested, please...
Last year I bought a DIY Waeco marine fridge unit. The compressor/condenser is a Danfoss BDF50 - www.seabreeze-industries.com.au/products/WAECO-CU95-Compressor-Condenser-115.htm. I decided to go the eutectic route, and bought the matching accumulator tank - www.seabreeze-industries.com.au/products/WAECO-VD06-Energy-Accumulator-121.htm.
The quality is good, and installation was easy. However, the compressor runs almost continuously to keep the eutectic tank frozen/partly discharged, which is obviously not ideal. The chest fridge insulation is 2 inches thick - not perfect, but acceptable. I'm now wondering if eutectic is the best solution for a chest fridge. Should I perhaps have gone for the evaporator plate - www.seabreeze-industries.com.au/products/WAECO-VD09-OEvaporator-111.htm type? Or would a freezer evaporator be more efficient - www.seabreeze-industries.com.au/products/WAECO-VD16-Circulating-Air-Evaporator-119.htm ?
If an evaporator plate is more efficient as a cooling unit, I would happily replace the eutectic tank. But, I'm reluctant to experiment... What is the general opinion - should a eutectic system run almost continuously? (btw, it has been checked by a fridge tech. Gas is OK, etc.) I know that an evaporator system cycles more frequently, but I still think that it will be better than very long periods of running.
Also, can anyone recommend an honest marine refrigeration specialist in Sydney who can check my system and recommend a fix?
Thanks...!
