Fan operation is starting point of our disagreement. I prefer evaporator fans cycling(with liquid solenoid) or fans with VFD. In that case liquid always present in the coil at evaporating temperature. When fans are off, liquid in the coil continue to evaporate, but at slower rate. Energy savings of this operation is significant. Evaporator fans using energy and release this energy into refrigerated space. This is additional(parasitic) refrigeration load. Usually, to remove the heat of 2HP fan we have to spend additional 1HP of refrigeration plant power. If we shut off this fan, we will save not 2HP but 3HP.
Regarding to 2 warm pallets in 600 pallets freezer. This isn't blast freezer. This is holding freezer. Majority of this pallets are cooled by natural convection. For them isn't important fan cycling or fan nonstop operation. Temperature of surrounding air is very important for them.
