Abstract
A refrigeration device includes an interior that is divided up into two refrigeration zones with each refrigeration zone having an evaporator and a compressor for supplying the evaporator with a refrigerant. A control for operating the compressors can be operated in different modes of operation depending on predetermined conditions. In a normal mode, the at least two compressors are exclusively operated at different times.
Claims20
A refrigeration appliance comprising:
- an interior divided into at least two refrigeration zones;
- a pair of evaporators each providing cooling of a respective refrigeration zone;
- a pair of compressors each supplying a respective one of the evaporators with refrigerant;
- and
- a controller for operating the compressors, the controller performing, in dependence upon selected predetermined conditions, a controlling function in a normal mode and a controlling function in at least one other operating mode and the controller, in the normal mode, controlling the operation of the pair of compressors such that, at any given time during the normal mode, only one of the two compressors is operating and the other of the two compressors is not operating.
A method for controlling a refrigeration appliance, the method comprising:
- in two refrigeration zones each having a respective compressor associated therewith, operating at the same time the two respective compressors associated with two refrigeration zones;
- and
- if a conditional limit is not exceeded, operating only one of the two respective compressors and not operating the other of the two compressors.
A refrigeration appliance comprising:
- an interior divided into at least two refrigeration zones, each refrigeration zone having a compressor to supply at least one evaporator with refrigerant,
- a controller to operate the compressors, wherein the controller is operable in different operating modes as a function of one or more predetermined conditions and wherein, in a normal mode, at least two compressors are operated exclusively at different times in alternating fashion.
A method for controlling a refrigeration appliance with at least two refrigeration zones and two compressors, wherein the compressors are operated at different, alternating times in predetermined conditions and are operable at the same time in parallel if the respective conditional limit is exceeded.
