## Abstract

A refrigeration device, in particular a domestic refrigeration device, has at least one storage chamber, a cold generator which refrigerates the storage chamber, and a regulating unit which regulates the performance of the cold generator and can be switched between an operating state of low average performance in which the performance of the cold generator is regulated in order to maintain the temperature of the storage chamber within a desired range, and an operating state of high average performance of the cold generator in which the temperature of the storage chamber falls below the desired range. A timer is designed to switch the refrigeration device periodically into the operating state of high average performance at times that can be set by the user.

## Claims

### Claim 1

A refrigeration device, in particular domestic refrigeration device, having at least one storage chamber, a cold generator cooling the storage chamber and a regulating unit regulating the power of the cold generator, which is regulated between an operating state of low average power (S1-S6), in which the power of the cold generator is regulated in order to keep the temperature of the storage chamber to within a target range ([T1(−1), T+1(+1)]), and an operating state of high average power of the cold refrigerator can be switched over, in which the temperature of the storage chamber drops to below the target range ([[T]1(−1), T1(+1)]), characterized by a time, which is configured to switch the refrigeration device periodically into the operating state of high average power at times that can be set by the user.

### Claim 2 (depends on 1)

The refrigeration device as claimed in claim 1, wherein the times are periodic in the weekly cycle.

### Claim 3 (depends on 1)

The refrigeration device as claimed in claim 1, wherein a start time of the operating state of high average power can be entered at a user interface.

### Claim 4 (depends on 1)

The refrigeration device as claimed in claim 1, wherein a time can be entered at a user interface, which is later than the start time of the operating state of high average power which is calculated therefrom.

### Claim 5 (depends on 1)

The refrigeration device as claimed in claim 1, wherein it is possible to set at a user interface whether the operating state of high average power is immediately to be followed again by the operating state of low average power, or whether the cold generator is to remain switched off, until the temperature in the storage chamber is increased to above the target range ([[T]1(−1), T1(+1)]).
