    Refrigerant Compression System of Refrigerator Using Intercooler
    The present invention relates to a refrigerant compression system of a refrigerator. More particularly, an intercooler is employed in a compressor of a refrigerator, and thus, the refrigerant is compressed in one stage, cooled, and then compressed again in two stages to reduce the energy consumption of the compressor. A refrigerant compression system.
    The refrigerator generally refers to an electric refrigerator cooled by using latent heat (evaporation heat) caused by a change of state of a substance.
    In addition, the electric refrigerator has a refrigerator for storing food, and has an ice maker by placing an ice tray on the surface of the evaporator, and at least two refrigerators for storing food, one of which has at least one refrigerator and one freezer. More than two are classified as refrigeration refrigerators.
    In the present invention, the conventional refrigerator means the freezer refrigerator.
    Typically, a refrigeration cycle that is applied to a refrigerator may be a compressor 1 (compressor), a hot pipe 2, a condenser 3 (condenser), a dryer 4, as shown in the block diagram shown in FIG. It consists of a capillary tube (5) (capillary tube), an evaporator (6) (everporator), and a section pipe (7), in which a certain amount of refrigerant is enclosed and circulated while changing from liquid to gas and gas to liquid. I'm making it.
    This will be described in more detail.
    The liquid refrigerant in the evaporator 6 is evaporated by depriving the heat necessary for evaporation from the air surrounding the evaporator, so that the deprived air is cooled and circulated by natural convection or a fan to keep the refrigerator at a low temperature.
    In the evaporator 6, the liquid refrigerant sent from the capillary tube 5 and the evaporated gas refrigerant coexist, and the phase change from liquid to gas is performed.
    The gaseous refrigerant evaporated in the evaporator 6 is sucked into the compressor 1 through the section pipe 7, and the refrigerant sucked in the compressor 1 is compressed in a state where it is easily liquefied by the cooling water or air at room temperature. That is, it turns into a gas refrigerant of high pressure and high temperature.
    The gas refrigerant compressed to high temperature and high pressure in the compressor 1 is heat-exchanged by cooling water or air at room temperature while passing through the hot pipe 2 and the condenser 3 to be converted into liquid refrigerant at room temperature and high pressure.
    The liquid refrigerant passes through the dryer 4 again to remove predetermined impurities and water, and the pressure decreases to a state where the liquid refrigerant is easily evaporated while passing through the carrier tube 5.
    The liquid refrigerant having such a low pressure is introduced into the evaporator 6 and evaporated while depriving the heat necessary for evaporation from the air surrounding the evaporator.
    In such a refrigeration cycle of the refrigerator, the compressor consumes more than 70% of the energy consumption of the entire refrigerator.
    Therefore, in order to reduce the energy consumption of the refrigerator, it is important to reduce the energy consumption of the compressor, that is, increase the efficiency of the compressor.
    The present invention has been made to reduce the overall energy consumption of the conventional refrigerator, the object of the refrigerator is to use the intercooler to reduce the energy consumed in the compressor by cooling and recompressing the refrigerant during the compression of the refrigerant by the compressor. The purpose of the present invention is to provide a refrigerant compression system.
    Refrigerant compression system of the refrigerator using an intercooler for achieving the object of the present invention,
    In compressing the gaseous refrigerant sucked from the evaporator into the compressor, the compressor is first compressed to a suitable pressure and then the intercooler is used to cool the first compressed refrigerant and then to compress it to the desired pressure. It has its features.

    Hereinafter, a refrigerant compression system of a refrigerator using an intercooler according to the present invention will be described in more detail with reference to the accompanying drawings.
    2 is a block diagram illustrating a refrigeration cycle to which a refrigerant compression system of a refrigerator using an intercooler according to the present invention is applied.
    Refrigerant compression system employing the intercooler according to the present invention, as shown in Figure 2, the conventional refrigeration cycle compressor (1), hot pipe (2), condenser (3), dryer (4), capillary tube (5) In the evaporator 6 and the section pipe 7, the intercooler 8 is further employed as the compressor 1.
    That is, when the refrigerant in the compressor 1 compresses the first stage from P1 to the appropriate pressure P2, the valve is operated at the pressure P2 so that the cooling gas of the intercooler 8 circulates inside the case of the compressor to cool the first stage compressed refrigerant. When the refrigerant is cooled to some extent, the compressor 1 again compresses the refrigerant to P4 in two stages.
    Therefore, the circulation passage of the cooling gas in the intercooler can be installed inside the compressor 1 case for this action. Preferably, a cooling gas circulation conduit of the intercooler is formed around the cylinder to which the compression is performed.
    Alternatively, a valve operating at an appropriate pressure P2 is installed in the cylinder of the compressor 1 in which the refrigerant is compressed, and the valve is connected to the intercooler 8 so that the refrigerant is compressed in the compressor in the first stage and then the intercooler 8 It is also possible to configure the refrigerant to be cooled and then again compressed in two stages in the compressor.
    The refrigerator refrigerant compression system using the intercooler according to the present invention configured as described above will be described with reference to FIGS. 3 and 4.
    3 is a P-h diagram of a conventional refrigerator refrigerant compression system, and FIG. 4 is a P-h diagram of a refrigerator refrigerant compression system according to the present invention.
    Referring to Figures 3 and 4 to see how much energy used by the conventional refrigerator and the compressor of the refrigerator according to the present invention, the conventional compressor is a gas refrigerant of high pressure, high temperature by the first stage compression of the sucked gas refrigerant The power dissipated in days can be calculated from the W comp. It can be seen that = m R (h4-h1).
    On the contrary, the amount of work consumed by the compressor in the refrigerant compression system of the refrigerator employing the intercooler according to the present invention is represented by W ' comp. = m R (h2-h1) + (h4'-h3) It can be seen that.
    Therefore, in the refrigerant compression system according to the present invention, the energy to be supplied to the compressor is significantly reduced as compared with the conventional art.
    As described above in detail, the refrigerant compression system of the refrigerator using the intercooler according to the present invention employs an intercooler in the compressor to cool the temperature of the refrigerant to some extent during the compression of the refrigerant, and then recompresses the energy consumption used for the compression. Has an effect.
