In a field test with three identical glass door cabinets, which are similar in heat load and humidity load, a defrost on demand (DOD) system was tested. At two glass door cabinets the DOD function was switched off. This resulted in an increase of the defrost capacity up to 141% compared with the cabinet which was still working under DOD. Switching off the DOD function also results in a 6% higher refrigeration load. On the basis of these results the importance of the DOD function at freezing plants and electrical defrost systems is hereby pointed out.
