Demand defrost. Does it work?

Author(s) : HOCKLER N.

Summary

Defrosting operations are usually set off by clocks and not according to real need, i.e., the amount of frost on the evaporators. Nevertheless, defrosting can be set in motion when it is necessary, through a reading of the pressure differential of the air flowing through the battery, the air speed, the flow rate of the refrigerant, or, better, the thickness of the frost itself. The different possibilities are discussed, along with the significant advantages that can be expected. A concrete example is given.
