Refrigerator And/Or Freezer Device

Abstract

The present invention relates to a refrigerator unit and/or a freezer unit having at least one carcass and having at least one inner space arranged in the carcass, wherein the unit has at least one refrigerant circuit that serves the cooling of the inner space and wherein the refrigerant circuit has at least one evaporator, at least one compressor, at least one condenser, and at least one restrictor, wherein at least one bypass to the restrictor is provided that extends directly or indirectly from the condenser to the evaporator and in which at least one valve is arranged for shutting off the bypass, with the evaporator and the bypass being arranged and configured such that a heat pipe effect is present in the bypass and/or in components arranged the direction of flow before and/or after it.

1 . A refrigerator unit and/or a freezer unit having at least one carcass and having at least one inner space arranged in the carcass, wherein the unit has at least one refrigerant circuit that serves the cooling of the inner space and wherein the refrigerant circuit has at least one evaporator, at least one compressor, at least one condenser and at least one restrictor

         2 . The refrigerator unit and/or the freezer unit in accordance with  claim 1 , characterized in that the bypass extends between the condenser and a collector connected downstream of the evaporator. 
     
     
         3 . The refrigerator unit and/or the freezer unit in accordance with  claim 1 , characterized in that the bypass extends between the condenser and the suction pipe that extends between the evaporator and the compressor. 
     
     
         4 . The refrigerator unit and/or the freezer unit in accordance with  claim 2 , characterized in that the collector is located in the refrigerated inner space. 
     
     
         5 . The refrigerator unit and/or the freezer unit in accordance with  claim 2 , characterized in that the collector is located outside the refrigerated inner space. 
     
     
         6 . The refrigerator unit and/or the freezer unit in accordance with  claim 1 , characterized in that the evaporator is configured such that the backflow of the condensed refrigerant from the bypass into the condenser takes place by gravity. 
     
     
         7 . The refrigerator unit and/or the freezer unit in accordance with  claim 1 , characterized in that the condenser is provided with at least one heat accumulator that serves as a heat reservoir for defrosting the evaporator. 
     
     
         8 . The refrigerator unit and/or the freezer unit in accordance with  claim 1 , characterized in that the condenser is connected to at least one heat accumulator. 
     
     
         9 . The refrigerator unit and/or the freezer unit in accordance with  claim 1 , characterized in that the evaporator is connected to at least one cold accumulator; and in that the bypass is arranged such that heat can be supplied to the cold accumulator by means of the bypass. 
     
     
         10 . The refrigerator unit and/or the freezer unit in accordance with  claim 1 , characterized in that conveying means are provided that are arranged such that they convey air to the condenser. 
     
     
         11 . The refrigerator unit and/or the freezer unit in accordance with  claim 10 , characterized in that at least one control device is provided that is configured to switch off the conveying means when the defrosting of the evaporator takes place. 
     
     
         12 . The refrigerator unit and/or the freezer unit in accordance with  claim 10 , characterized in that at least one control device is provided that is configured to put the conveying means into operation or to leave it switched on when the defrosting of the evaporator takes place. 
     
     
         13 . The refrigerator unit and/or the freezer of  claim 1 , wherein said restrictor is a capillary. 
     
     
         14 . The refrigerator unit and/or the freezer unit in accordance with  claim 1 , characterized in that the condenser is connected to at least one heat accumulator and is arranged in a liquid bath. 
     
     
         15 . The refrigerator unit and/or the freezer unit of  claim 14 , wherein said liquid bath is a water bath. 
     
     
         16 . The refrigerator unit and/or the freezer unit in accordance with  claim 1 , characterized in that one or more fans are provided that are arranged such that they convey air to the condenser. 
     
     
         17 . The refrigerator unit and/or the freezer unit in accordance with  claim 2 , characterized in that the bypass extends between the condenser and the suction pipe that extends between the evaporator and the compressor.
