Refrigeration apparatus

Abstract

A refrigeration apparatus includes: a first cooling device that detects a temperature of a first area of a storage chamber and cools the first area; a second cooling device that detects a temperature of a second area of the storage chamber and cools the second area; and a controller that controls a cooling operation of the first cooling device and a cooling operation of the second cooling device in a coordinated manner based on a detected temperature of one cooling device of the first cooling device and the second cooling device.

1 . A refrigeration apparatus, comprising:
 a first cooling device that detects a temperature of a first area of a storage chamber and cools the first area;   a second cooling device that detects a temperature of a second area of the storage chamber and cools the second area; and   a controller that controls a cooling operation of the first cooling device and a cooling operation of the second cooling device in a coordinated manner based on a detected temperature of one cooling device of the first cooling device and the second cooling device.   
     
     
         2 . The refrigeration apparatus according to  claim 1 , wherein
 the one cooling device is a cooling device having a higher detected temperature between the first cooling device and the second cooling device.   
     
     
         3 . The refrigeration apparatus according to  claim 1 , wherein
 the controller sets, after setting the cooling operation of the one cooling device to an ON state, the cooling operation of the other cooling device of the first cooling device and the second cooling device to the ON state.   
     
     
         4 . The refrigeration apparatus according to  claim 3 , wherein
 the controller sets, after setting the one cooling device to the ON state, the cooling operation of the one cooling device to an OFF state based on the detected temperature of the one cooling device, and   the controller sets, at a time when setting the cooling operation of the one cooling device to the OFF state, the cooling operation of the other cooling device to the ON state.   
     
     
         5 . The refrigeration apparatus according to  claim 1 , wherein
 the first cooling device includes a first compressor for circulating a first refrigerant,   the second cooling device includes a second compressor for circulating a second refrigerant,   the first compressor repeats a first cycle operation including an ON state and an OFF state, under control of the controller,   the second compressor repeats a second cycle operation including the ON state and the OFF state, under the control of the controller, and   a second cycle time of the second cycle operation is equal to a first cycle time of the first cycle operation.   
     
     
         6 . The refrigeration apparatus according to  claim 1 , wherein
 the first cooling device includes: a first compressor for circulating a first refrigerant; a first cooling unit for cooling the storage chamber by the first refrigerant; and a first heater disposed around the first cooling unit,   the second cooling device includes: a second compressor for circulating a second refrigerant; a second cooling unit for cooling the storage chamber by the second refrigerant; and a second heater disposed around the second cooling unit, and   the controller drives the first heater in an OFF state of the first compressor, and drives the second heater in the OFF state of the second compressor.   
     
     
         7 . The refrigeration apparatus according to  claim 1 , wherein
 the first area is an area of a right half portion of the storage chamber, and   the second area is an area of a left half portion of the storage chamber.
