Definitions

  • the present invention relates to a refrigerator having a compressor whose operating mode and speed can be changed.
  • Refrigerators enable in particular food products to be kept cool and thereby their shelf life to be prolonged.
  • Refrigerators generally comprise at least two compartments, namely a cooler and a freezer compartment. Heat drawn from said compartments by means of a refrigerant is discharged to environment and the compartments of a refrigerator are thus cooled.
  • a refrigerant is pressurized by a compressor and used in refrigerant cycle.
  • Drop-in compressors are used with an inverter card.
  • operating modes of drop-in compressors cannot be changed.
  • required cooling cannot be provided because such compressors can only be operated in on and off positions. In this operating manner, a compressor provides either excessive or insufficient cooling.
  • the aim of the present invention is to realize a refrigerator having a compressor whose operating mode and speed can be changed.
  • Another aim of the present invention is to realize a cooling system with enhanced efficiency.
  • Figure 1 is a schematic view of the refrigerator.
  • Figure 2 is a view of the control signals.
  • the refrigerator (1) having a compressor whose operating mode and speed can be changed, comprises in its most basic form,
  • the refrigerator (1) having a compressor whose operating mode and speed can be changed comprises at least one compressor (2) enabling pressurizing a refrigerant.
  • the compressor (2) pressurizes the refrigerant, thereby enabling the refrigerant to efficiently circulate in a refrigerant cycle.
  • the compressor (2) is driven by means of the inverter (3).
  • the inverter (3) drives the compressor (2) by means of control signals it receives from the control unit (4).
  • the control unit (4) may send varying signals to the inverter (3) depending on the internal temperature of the refrigerator (1).
  • the internal temperature of the refrigerator (1) may be measured by means of a heat sensor. In another embodiment, a thermostat may be used, enabling determining whether said temperature exceeds a given value.
  • control unit (4) may be connected to a switch enabling determining the refrigerator (1) door being opened and closed.
  • the control unit (4) can thus send a different signal to the inverter (3) after the refrigerator (1) door is opened and closed.
  • the control unit (4) determines when, for how long and how the compressor (2) will operate by means of electrical signals it sends to the inverter (3).
  • control unit (4) sends commands to the inverter (3) by means of electrical signals.
  • Said electrical signals may be a signal formed by successively arranging 1 and 0 binary logic values simply in a given sequence, as well as arranging them so as to consist a complex signal containing information such as a preamble, message or a verification code.
  • control signals sent by the control unit (4) to the inverter (3) contain logical signal levels each of which has a predetermined duration and contains a predetermined number of values.
  • a control signal may contain ten logical signal levels which are successively arranged, each of which continues for one second. In this case, each control signal continues for ten seconds.
  • Each different arrangement of said logic levels enable producing a different command.
  • the control unit (4) is able to generate different commands by modifying the arrangement of said logic levels. An example to such an application is given in Figure 2.
  • the commands of the control unit (4) can enable the compressor (2) to operate in operating modes such as turbo function, door opened function and cold-start function.
  • turbo function enables the compressor (2) to be operated with maximum power for a predetermined duration, independently of the temperature in the compartment desired to be cooled and of the state of the thermostat.
  • Door opened function is used to compensate for the warm air introduced into the refrigerator (1) after the refrigerator (1) door being opened and closed.
  • the compressor (2) is operated with a speed faster than normal operating speed for a predetermined duration, and the normal operating speed is resumed afterwards.
  • cold-start function the compressor (2) starts operating in cold-start speed and drop-in function is realized by starting from this speed.
  • Operation in cold-start mode may be delimited for each cycle with, for example two hours.
  • the above modes are solely given with the purpose of exemplification and very different operating modes can be developed depending on requirements. What matters here is being capable of changing operating mode of the compressor (2) according to commands sent by the control unit (4) to the inverter (3).

Abstract

La présente invention concerne un réfrigérateur (1) ayant un compresseur (2) dont le mode de fonctionnement peut être changé. Le réfrigérateur (1) de l'invention est caractérisé par au moins une unité de commande (4) apte à envoyer des signaux de commande à l'onduleur (3) et à commander ainsi le moment, la durée et le mode de fonctionnement du compresseur (2).
