Process for completing the defrosting of the evaporator of a heat pump

摘要

In a process for completing the defrosting of the evaporator of an air/water heat pump, the refrigerant circuit of which is reversible from heating operation to defrosting operation, the defrosting operation is terminated in dependence on a differential ( DELTA theta ) (spreading), between the return and feed temperature of the water, preferably lying at a relative temperature of between -2 and +2K. <IMAGE>
