1. A method for operating a cooling device for an object, the cooling device having a refrigerant circuit with a compressor, a condenser, an expansion element and an evaporator, a cold air flow for the object exchanging heat with a refrigerant in the evaporator, the cooling device further having a defroster for de-icing the evaporator, which comprises the steps of:
controlling the defroster according to a degree of icing of the evaporator; and
determining the degree of icing of the evaporator on a basis of a first temperature of the cold air flow from the object to the evaporator, a second temperature and/or an operating pressure of the refrigerant upstream of the evaporator and at least one operating parameter of the compressor.
