Abstract
A method initializes a defrosting operation in a refrigeration appliance having a speed-controlled compressor. The method includes the steps of: a) starting up the compressor at a speed set to an initial value, b) adjusting the speed of the compressor in order to prevent a temperature in a storage chamber of the refrigeration appliance from deviating from a target temperature, c) monitoring a deviation between an adjusted speed and the initial value, and d) deciding that defrosting is necessary if the deviation exceeds a limit value.

A method for initializing a defrosting procedure in a refrigeration appliance with a variable speed compressor, which comprises the steps of:
- a) starting up the variable speed compressor with a rotational speed nt set to an initial value n0;
- b) adapting the rotational speed nt of the variable speed compressor, in order to prevent a temperature of a storage chamber of the refrigeration appliance from drifting from a setpoint temperature;
- c) monitoring a deviation between an adapted rotational speed nt and the initial value n0;
- and
- d) deciding that defrosting is necessary when the deviation exceeds a limit value.
A refrigeration appliance, comprising:
- at least one storage chamber;
- a variable-speed compressor for cooling said at least one storage chamber;
- and
- a controller for regulating a rotational speed of said variable speed compressor on a basis of a temperature measured in said at least one storage chamber, said controller configured to initializing a defrosting procedure in the refrigeration appliance by said controller being programmed to:
- a) start up said variable speed compressor with the rotational speed nt set to an initial value n0;
- b) adapt the rotational speed nt of said variable speed compressor, in order to prevent the temperature of said at least one storage chamber of the refrigeration appliance from drifting from a setpoint temperature;
- c) monitor a deviation between an adapted rotational speed nt and the initial value n0;
- and
- d) decide that defrosting is necessary when the deviation exceeds a limit value.
A non-transitory computer readable medium having computer readable instructions that enable a computer to carry out a method for initializing a defrosting procedure in a refrigeration appliance with a variable speed compressor, which comprises the steps of:
- a) starting up the variable speed compressor with a rotational speed nt set to an initial value n0;
- b) adapting the rotational speed nt of the variable speed compressor, in order to prevent a temperature of a storage chamber of the refrigeration appliance from drifting from a setpoint temperature;
- c) monitoring a deviation between an adapted rotational speed nt and the initial value n0;
- and
- d) deciding that defrosting is necessary when the deviation exceeds a limit value.
