Single circuit refrigeration appliance

Abstract

A single-circuit refrigeration appliance includes a thermally insulated housing and a refrigerant circuit in which the following are connected in series between a pressure connection and a suction connection of a compressor: a condenser, a first throttle point, a first evaporator that cools a first storage compartment in the housing, a second throttle point, and a second evaporator that cools a second storage compartment in the housing. The second throttle point has an adjustable volume flow rate.

1 - 9 . (canceled) 
     
     
         10 . A single-circuit refrigeration appliance, comprising:
 a thermally insulated housing;   a first storage compartment and a second storage compartment formed in said housing; and   a refrigerant circuit including a compressor having a pressure connection and a suction connection and the following connected in series between said pressure connection and said suction connection:
 a condenser, 
 a first throttle point, 
 a first evaporator cooling said first storage compartment, 
 a second throttle point having an adjustable volume flow rate, and 
 a second evaporator cooling said second storage compartment. 
   
     
     
         11 . The single-circuit refrigeration appliance according to  claim 10 , wherein said evaporators are cold wall evaporators. 
     
     
         12 . The single-circuit refrigeration appliance according to  claim 10 , which further comprises:
 a first temperature sensor disposed in said first storage compartment; and   a control circuit connected to said first temperature sensor and configured to increase said volume flow rate of said second throttle point if cooling is required in said first storage compartment.   
     
     
         13 . The single-circuit refrigeration appliance according to  claim 10 , which further comprises:
 a second temperature sensor disposed in said second storage compartment; and   a control circuit connected to said second temperature sensor and configured to reduce said volume flow rate of said second throttle point if cooling is required in said second storage compartment.   
     
     
         14 . The single-circuit refrigeration appliance according to  claim 10 , wherein:
 said compressor is a speed-controlled compressor having a rotational speed; and   a control circuit is configured to increase said rotational speed of said speed-controlled compressor if cooling is required in said first and second storage compartments.   
     
     
         15 . The single-circuit refrigeration appliance according to  claim 10 , wherein said first throttle point has a volume flow rate, and said volume flow rate of said second throttle point in a maximum opening state is larger than said volume flow rate of said first throttle point. 
     
     
         16 . The single-circuit refrigeration appliance according to  claim 10 , wherein said second throttle point has a continuous valve. 
     
     
         17 . The single-circuit refrigeration appliance according to  claim 10 , wherein at least said second storage compartment is operable as a freezer compartment. 
     
     
         18 . The single-circuit refrigeration appliance according to  claim 10 , wherein at least said first storage compartment is operable as a normal refrigerator compartment.
