Refrigeration system

Abstract

A refrigeration system includes a controller ( 90 ) for controlling operation restart after a breaker trips owing to failure in electric systems for refrigeration system components. The controller ( 90 ) includes a sequential startup section ( 91 ) for, upon the operation restart, sequentially starting up target compressors ( 2 A, 2 B, 2 C) and outdoor fans (F 1 , F 2 ) previously selected from among the refrigeration system components, and failure processing section ( 92 ) for, if the breaker trips again during the sequential startup of the target compressors and outdoor fans, excluding the compressor or outdoor fan ( 2 A, . . . ) supplied with electric power just before the breaker's trip from the target refrigeration system components to be started up by the sequential startup section ( 91 ). Thus, a failed component is identified by the failure processing section ( 92 ) and only the normal components, leaving out the failed component, are then started up, thereby resuming the operation.

1 . A refrigeration system for performing a refrigeration operation in which electric systems of refrigeration system components ( 2 A,  2 B, . . . ) are supplied with electric power from a power supply through a breaker, the refrigeration system comprising: 
 sequential startup means ( 91 ) for, upon operation restart after the breaker trips owing to failure in the electric systems, sequentially starting up target refrigeration system components ( 2 A,  2 B, . . . ) previously selected from among the refrigeration system components; and    failure processing means ( 92 ) for, if the breaker trips again owing to failure in the electric systems during the sequential startup of the target refrigeration system components through the sequential startup means ( 91 ), excluding the refrigeration system component ( 2 A,  2 B, . . . ) supplied with electric power just before the occurrence of the failure from the target refrigeration system components to be started up by the sequential startup means ( 91 ).    
   
   
       2 . The refrigeration system of  claim 1 , further comprising transition means ( 93 ) for, when the target refrigeration system components ( 2 A,  2 B, . . . ) to be started up by the sequential startup means ( 91 ) are all normally started up, making a transition to a normal operation while holding in a halted state the refrigeration system component ( 2 A,  2 B, . . . ) excluded from the target refrigeration system components by the failure processing means ( 92 ).  
   
   
       3 . The refrigeration system of  claim 1 , wherein the target refrigeration system components to be sequentially started up by the sequential startup means ( 91 ) are a plurality of compressors ( 2 A,  2 B,  2 C).  
   
   
       4 . The refrigeration system of  claim 1 , wherein the target refrigeration system components to be sequentially started up by the sequential startup means ( 91 ) are a plurality of compressors ( 2 A,  2 B,  2 C) and a plurality of fans (F 1 , F 2 ).
