Problems solved by technology

[0007] However, this proposal offers the disadvantage that when the controller is activated in the first compartment where a disturbance occurs, the second compartment is also affected by this same control situation
[0010] Therefore, the prior art does not include a refrigeration system control method adapted to independently control the temperature of two (or more) compartments by a compressor acting on more than one suction line

Embodiment Construction

[0037] exist figure 1 In the initial mention of , the present invention relates to a control method for a refrigeration system 10 , and more specifically, to a control method for a refrigeration system 10 including a compressor 1 . In a non-limiting example, compressor 1 may be configured as a double-suction compressor, such as figure 1 shown in . However, it should be emphasized that the teaching presented herein is not limited to its application in double suction compressors, whereby any compressor known in the prior art is suitable for employing the concepts presented herein.

[0038] In general, compressor 1 must be understood as a compressor associated with at least two suction lines, eg figure 1 , Figure 6 , Figure 7 and Figure 8 Compressor 1 shown in . It should therefore be noted that the compressor 1 comprises at least a first suction line L 1 and the second suction line L 2 . According to the teaching of the present invention, the suction line L 1 , L 2...

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.

Description

technical field [0001] The invention relates to a method and control system for a refrigeration system. More specifically, the invention proposes a method and a control system for a refrigeration system using a compressor acting on more than one suction line. The invention also proposes a refrigeration device. Background technique [0002] Most refrigeration appliances (ie, refrigerators) currently used for storing food at low temperatures have at least two refrigeration environments, basically consisting of a freezer and a freezer (refrigerator compartment). [0003] To cool these compartments, a double-suction compressor can be used, which means a compressor comprising two gas suction lines, each of which is associated with a compartment to be cooled, such as for example a refrigerator and a freezer. [0004] Since the capacity needs of each compartment are different, and also because they perform different functions, solutions have been developed to respond to the needs...
