MANAGEMENT DEVICE FOR PLURAL PIECES OF FREEZING/REFRIGERATING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a management device capable of performing pressure setting to a refrigerating machine to which plural pieces of freezing and refrigerating equipment are connected without depending on an expert engineer.;SOLUTION: There is provided a management device used for a refrigeration cycle in which a discharged refrigerant of a compressor is supplied to use side heat exchangers incorporated into each of the plural pieces of freezing/refrigerating equipment through at least a heat source side heat exchanger and a refrigerant pipe. The management device comprises: an acquisition part for acquiring information on the kind of the refrigerant used in the refrigeration cycle, a connection state of the refrigerant pipe, and uses of the plural pieces of freezing/refrigerating equipment; and a control part for determining a control target range of refrigerant evaporation pressure at each of the use side heat exchangers on the basis of the information on the kind of the refrigerant used in the refrigeration cycle, the connection state of the refrigerant pipe and the uses of the plural pieces of freezing/refrigerating equipment, which is acquired at a communication part.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2017,JPO&INPIT
