Abstract

Process and device for the monitoring and control of an evaporator (1) in particular the evaporator of a heat pump according to which is compared, at predetermined instants, the variation between the upstream (9) and downstream (10) temperatures or pressures of the air current crossing the evaporator, defrosting of the evaporator being initiated when said difference exceeds a reference value. <IMAGE>
