Abstract
A method for operating a refrigeration appliance includes the steps of running a compressor and opening at least one of a first branch and a second branch, where the first branch has a first evaporator, the second branch has a second evaporator, and the first branch and the second branch are connected in parallel at inlets thereof. The method further determines, according to an ambient temperature, whether the first branch is open after the compressor is turned off and determines, based on the ambient temperature, whether the second branch is open after the compressor is turned off.
Claims12
A cooling appliance, comprising:
- a compressor;
- a plurality of branches connected in parallel at inlets thereof, wherein each of said branches having a corresponding evaporator;
- a fluid controller, configured to selectively open at least one of said branches, so that when said compressor is running, said corresponding evaporator in an opened branch of said branches is supplied with a refrigerant output from said compressor;
- and
- a controller configured to determine, based on an ambient temperature, whether at least one of said branches is open or should be opened after said compressor is turned off, wherein when the ambient temperature is within a first ambient temperature range, at least one of said branches is closed after a turning-off of said compressor, and when the ambient temperature is outside of the first ambient temperature range, said at least one branch is open after a turning-off of said compressor, wherein the first ambient temperature range includes a lower limit less than 15 degrees Celsius and an upper limit greater than 20 degrees Celsius.
A cooling appliance, comprising:
- a compressor;
- a first branch having a first evaporator and a first inlet;
- a second branch having a second evaporator and a second inlet, said first inlet of said first branch and said second inlet of said second branch are connected in parallel, wherein when said compressor is running and said first branch is open, said first evaporator is supplied with a refrigerant output from said compressor, and when said compressor is running and said second branch is open, said second evaporator is supplied with the refrigerant output from said compressor;
- and
- a controller coupled to said compressor, said controller configured to determine, based on an ambient temperature, whether said first branch is open or should be opened after said compressor is turned off, and/or said controller is configured to determine, based on the ambient temperature, whether said second branch is open or should be opened after said compressor is turned off, and wherein when the ambient temperature is within a first ambient temperature range, said first branch is closed after a turning-off of said compressor, and when the ambient temperature is outside of the first ambient temperature range, said first branch is open after a turning-off of said compressor, wherein the first ambient temperature range includes a lower limit less than 15 degrees Celsius and an upper limit greater than 20 degrees Celsius.
