<p><P>PROBLEM TO BE SOLVED: To provide a freezing and refrigeration system that performs determination related to an overload based on a load state of the whole refrigerant circuit including a condensing unit and a showcase. <P>SOLUTION: The system includes: one or more condensing units 200 which have a compressor 203 for compressing and discharging a refrigerant and a condenser 204 for condensing the refrigerant by heat exchange; one or more showcases 100 which have an expansion valve 103 for decompressing the refrigerant and an evaporator 104 for cooling air in a storage chamber by heat exchange with the refrigerant related to the decompression, in which the condensing units and the showcases are connected with pipes to form the refrigerant circuit for circulating the refrigerant; and a controller 202 for the condensing units which determines the load states in the condensing units 200 and the showcases, and determines a cause of an overload state on the basis of the determination to output it. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
