    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.

  • Patent number: 10495080
    Abstract: The present invention relates to the technological field of acoustic filters applied to hermetic compressors. Problem to be solved: In hermetic compressors applied in cooling system, the work fluid sucked by the compression mechanism is hotter than the work fluid coming from the evaporator, and it is known that greater the temperature of this fluid, smaller is the efficiency of the compressor. Resolution of the problem: It is revealed a suction acoustic filter and a suction line including this acoustic filter capable of guarantee that the compression mechanism works mainly with the work fluid coming from the evaporator, which is colder than the work fluid accumulated inside the environment defined by the hermetic housing of compressor.

  • Publication number: 20190220806
    Abstract: A method for determining the presence and arrangement of products arranged in a cooling system, the method including at least the steps of: capturing at least one piece of data on the product arranged in the cooling system from a piece of image data on the product, locally processing the piece of image data, sending the processed data to a remote system, checking whether the processed data relates to a known product, registering the product if same relates to an unknown product, updating the piece of information data on the product and establishing the product as a known product, analyzing the processed data on the product and generating at least one action determining the presence and arrangement of the product, and notifying a user of at least one of the actions determining the presence and arrangement of the product.

  • Patent number: 10344754
    Abstract: A method for detecting an improper opening of a multiple suction reciprocating compressor suction valve of a reciprocating compressor includes monitoring, by an electronic processing core, a variable proportional to torque of an electrical engine that cooperates with a piston of the reciprocating compressor, the variable being measured by a sensor. A detection of the improper opening of the suction valve is made by a detection of at least one peak of the variable proportional to torque of the electrical engine during power of the electromagnetic field generator element.

  • Patent number: 10337768
    Abstract: A method for controlling and adjusting the refrigeration capacities of a refrigeration system equipped with a double suction compressor, the refrigeration system including first and second compartments to be refrigerated and including first and second evaporators respectively positioned in the first and second compartments. The double suction compressor is controlled to alternate its compression capacity with high-frequency between first and second refrigerant suction lines respectively associated with the first and second evaporators such that the first and second compartments are simultaneously cooled. The compression capacity of the compressor is applied to the first and second suction lines based upon respective first and second duty cycles that together account for 100 percent of the compression capacity of the compressor. First and second temperature sensors are associated with the first and second compartments and provide temperature values that are used to select the first and second duty cycles.

  • Patent number: 10309383
    Abstract: The arrangement of the present invention is applied to a compressor which comprises a bearing hub housing a crankshaft and presenting at least a first and a second bearing portion, spaced apart by a circumferential recess. The crankshaft presents at least a first and a second support portion, spaced apart by a circumferential recess, which is offset from the circumferential recess of the bearing hub. At least one of the bearing portions and support portions has an axial extension superior to that required for radially bearing the crankshaft, the first and second bearing portions defining, with the first and second support portions, respectively, a first and a second radial bearing regions having the axial extensions required for a radial bearing for the crankshaft, presenting lower loss by viscous friction.
