US 2019/0376734 A1 · METHOD AND CONTROL SYSTEM FOR A REFRIGERATION SYSTEM AND REFRIGERATION APPLIANCE

Abstract

A control method for a refrigeration system (10), with the refrigeration system (10) including at least one compressor (1) associated with at least one pair of suction lines (L2, L3, . . . LN), with each of the suction lines (L2, L3, . . . LN) respectively associated with at least one refrigerated environment (C1, C2, . . . CN). The method includes generating a system equivalent (Seq) to the refrigeration system, with the equivalent system (Seq) comprising at least one control parameter (PC1, PC2, . . . PCN) associated with each of the refrigerated environments (C1, C2, . . . CN). A control system for a refrigeration system and a refrigeration appliance are also described.

A control method for a refrigeration system (10), the refrigeration system (10) comprising at least one compressor (1) and at least one pair of suction lines (L1, L2 . . . LN), with each of the suction lines (L1, L2 . . . LN) respectively associated with at least one refrigerated compartment (C1, C2, . . . CN), wherein the method comprises:

generating equivalent compressors for each suction line (L1, L2 . . . LN), with the equivalent compressors comprising at least one control parameter (PC1, PC2 . . . PCN) associated with each of the refrigerated environments (C1, C2, . . . CN), wherein the equivalent compressors are independent of each other.

A control system of a refrigeration system (10), the refrigeration system (10) comprising:

at least one compressor (1) associated with at least one pair of suction lines (L1, L2, . . . LN), with each of the suction lines (L1, L2, . . . LN) respectively associated with at least one refrigerated compartment (C1, C2, . . . CN);
the control system comprising at least one control parameter (PC1, PC2, . . . PCN) associated with each refrigerated compartment (C1, C2, . . . CN) and obtained from at least one control loop (MC1, MC2, . . . MCN) associated with each refrigerated compartment (C1, C2, . . . CN).

A refrigeration appliance (20) comprising a compressor (1), with the compressor (1) being associated with at least one pair of suction lines (L1, L2, . . . LN), and with each of the suction lines (L1, L2, . . . LN) respectively associated with at least one refrigerated compartment (C1, C2, . . . CN), the refrigeration appliance (20) further comprising:

at least one control parameter (PC1, PC2, . . . PCN) associated with each refrigerated compartment (C1, C2, . . . CN) and obtained from at least one control loop (MC1, MC2, . . . MCN) associated with each refrigerated compartment (C1, C2, . . . CN), whereby the control parameters (PC1, PC2, . . . PCN) are independent for each of the refrigerated compartments (C1, C2, . . . CN) and are related to the refrigeration appliance (20) capacity parameters, whereby the current temperatures (TC1, TC2, . . . TCN) of the refrigerated compartments (C1, C2, . . . CN) reach the respective reference temperatures (TREFC1, TREFC2, . . . TREFCN) of the refrigerated compartments.
