Not true. I have a walkin cooler that the fans run 24/7. The compressor runs when needed. Yes, the evaporator is below freezing and collects some ice, but whenever the compressor shuts down, the fans are blowing "above freezing" air through it. It melts the ice, drips on a pan and drains out the side.

We also have a walkin freezer. It has a much more complicated system because there is no "above freezing" air to defrost the coils.
