Refrigeration Installation and Method for Operating a Refrigeration Installation

Abstract

A refrigerating system comprises at least one refrigerating consumer provided with at least one evaporator, at least one supply line and at least one withdrawal line which enable the coolant or the coolant mixture to be supplied to and/or withdrawn from the refrigerating consumer(s). Expansion elements are associated with the evaporator(s). The expansion elements are embodied as modified expansion valves and/or as modified linear expansion machines or the by-pass lines are associated therewith, and a modified linear compressor or a traditional compressor, which comprises a by-pass line is associated with each refrigerating consumer. The modified expansion valve(S) and/or the modified linear expansion machine(s) and/or the modified linear compressor(s) have a working position which enables a through-flow without a considerable drop in pressure.

1 - 6 . (canceled)  
   
   
       7 . A refrigeration installation having at least one refrigeration consumer, which includes at least one evaporator, having at least one feed line and at least one discharge line, via which a refrigerant or a refrigerant mixture is fed to the at least one refrigeration consumer and discharged from the at least one refrigeration consumer, the at least one evaporator having expansion members, wherein 
 the expansion members being designed as modified expansion valves and/or as modified linear expansion machines or being assigned bypass lines, and    each said refrigeration consumer being assigned a modified linear compressor or a conventional compressor, which includes a bypass line, and    the modified expansion valves and/or the modified linear expansion machines and/or the modified linear compressors having a working position which allows flow to pass through without a significant pressure drop.    
   
   
       8 . The refrigeration installation as claimed in  claim 7 , wherein 
 the at least one refrigeration consumer has a dedicated closed refrigerant or refrigerant mixture cycle,    the refrigerant or refrigerant mixture cycle being operatively connected via at least one liquifier to the at least one feed line and the at least one discharge line, and    the refrigerant or refrigerant mixture cycle in each case having modified expansion valves and/or modified linear expansion machines or conventional valves with associated bypass lines and modified linear compressors or conventional compressors with associated bypass lines,    the evaporator of said at least one refrigeration consumer in each case being arranged higher than the liquifier of the said at least one refrigeration consumer.    
   
   
       9 . The refrigeration installation as claimed in  claim 7 , wherein a plurality of refrigeration consumers are connected to one another and/or to the at least one feed line and the at least one discharge line by means of couplings.  
   
   
       10 . The refrigeration installation as claimed in  claim 9 , wherein said couplings are quick-fit couplings.  
   
   
       11 . The refrigeration installation as claimed in  claim 7 , wherein said at least one of the refrigeration consumers is assigned supercoolers as internal heat exchangers.  
   
   
       12 . A method for operating the refrigeration installation as claimed in  claim 7 , comprising assigning at least one refrigeration consumer modified expansion valves and modified linear compressors, and during the defrosting phase of at least one of the refrigeration consumers moving at least one of the modified expansion valves and at least one of the modified linear compressors of the refrigeration consumers which are to be defrosted into a working position in which through-flow without a significant pressure drop is possible.  
   
   
       13 . A method for operating a refrigeration installation as claimed in  claim 7 , comprising assigning at least one conventional expansion valve and at least one conventional compressor of the at least one refrigeration consumer bypass lines, and during a defrosting phase of the at least one refrigeration consumer, opening the bypass lines, and taking the at least one associated conventional expansion valve and the at least one associated conventional compressor out of operation.
