Benefits of technology

This patent is about a refrigerator that can control the amount of refrigerant that is supplied to its evaporators based on the cooling load. This helps to improve energy efficiency by reducing energy consumption when the refrigerator is running at low load. It also allows for quicker response times when there is a sudden increase in load. Overall, this technology helps to save energy and improve the performance of refrigerators.

Problems solved by technology

The refrigerators has a problem in that it is difficult to take efficient measures against cooling load that changes in accordance with environments such as the internal temperature of the compartments or the temperature of the external air, when the amount of refrigerant that is supplied to the evaporator is not appropriately controlled.

first embodiment

[0027]Referring to FIGS. 1 to 4, a refrigerator according to the present invention includes a compressor 1 that compresses a refrigerant, a condenser 2 that condenses the refrigerator compressed by the compressor 1, a first evaporator 5 and a second evaporator 8 that evaporate a refrigerant, a distributor 50 that distributes the refrigerant condensed by the condenser 2 to at least one of the first evaporator 5 and the second evaporator 8, a plurality of refrigerant channels 15 and 16 that is provided to supply the refrigerant distributed by the distributor 50 to the first evaporator 5, one or more second refrigerant channels 22 and 23 that are provided to supply the refrigerant distributed by the distributor 50 to the second evaporator 8, and a plurality of capillary tubes that is disposed in the first refrigerant channels and the second refrigerant channels, respectively.

[0028]The distributor 50 may include a first distributor 51 that distributes the refrigerant condensed by the co...

second embodiment

[0059]Referring to FIG. 2, a refrigerator according to the present invention includes a distributor 54 that selectively distributes a refrigerant condensed by a condenser 2 to a plurality of first refrigerant channels 15 and 16 and at least one second refrigerant channel 22. The distributor 54 can selectively distribute a refrigerant in accordance with cooling load. The distributor 54 may be connected with a discharged-from-condenser refrigerant channel 13 through which the refrigerant condensed by the condenser 2 is guided. The distributor 54 may be connected with the first refrigerant channels 15 and 16 or at least one second refrigerant channel 22.

[0060]The distributor 54 may include three or more refrigerant outlet connected with the first refrigerant channels 15 and 16 or the second refrigerant channel 22, and for example, it may be implemented by a 4-way valve. The 4-way valve means a valve with four ports herein. The first expansion refrigerant supply channel 15, the second e...

third embodiment

[0071]Referring to FIG. 3, a refrigerator according to the present invention includes a distributor 55 that distributes a refrigerant condensed by a condenser 2 to a plurality of refrigerant channels 15′ and 22′, capillary tubes 3′ and 6′ that are disposed in the refrigerant channels 15′ and 22′ and expand a refrigerant, and an evaporator 5′ that evaporates the refrigerant expanding through the capillary tubes 3′ and 6′.

[0072]Although it is exemplified that the distributor 55 distributes a refrigerant to a first refrigerant channel 15′ and a second refrigerant channel 22′ in the following description, the present invention is not limited thereto.

[0073]The distributor 55, a device that distributes the refrigerant condensed by the condenser 2 the first refrigerant channel 15′ and / or the second refrigerant channel 22′, may be implemented by a 3-way valve. The 3-way valve means a valve with three ports for a refrigerant herein. The distributor 55 can be controlled by appropriate control...

Abstract

A refrigerator is provided. The refrigerator includes a compressor configured to compresses a refrigerant, a condenser configured to condense the refrigerant compressed by the compressor, a first evaporator and a second evaporator configured to evaporate the refrigerant condensed by the condenser, a distributor configured to distribute the refrigerant condensed by the condenser to at least one of the first evaporator and the second evaporator, a plurality of first refrigerant channels configured to supply the refrigerant distributed from the distributor to the first evaporator, at least one second refrigerant channel configured to supply the refrigerant distributed from the distributor to the second evaporator and a capillary tube disposed in each of the first refrigerant channels and the at least one second refrigerant channel.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Application No. 10-2012-0007264, filed Jan. 25, 2012, Korean Application No. 10-2012-018598, filed Feb. 23, 2012 and Korean Application No. 10-2012-0018599, filed Feb. 23, 2012, the contents of which are herein incorporated by reference in their entireties.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a refrigerator that can store food at a low temperature.[0004]2. Description of Related Art[0005]In general, refrigerators are apparatuses that store food at a low temperature for a long time by keeping the interior temperature lower than the room temperature.[0006]Refrigerators are equipped with a cooling system composed of a compressor, a condenser, an expansion device, and an evaporator. A refrigerant at a high temperature and a high pressure, discharged from the compressor, is condensed by the condenser and is then supplied to the evaporator ...
