    摘要： The present invention provides a refrigerator, comprising a storage compartment and a mixed air passage. Both ends of the mixed air passage have air inlets, the middle portion of the mixed air passage comprises a mixed air outlet communicating with the storage compartment, and the mixed air passage is configured to receive air flows from the two air inlets such that two air flows enter the storage compartment in a mixed manner via the mixed air outlet. The refrigerator of this invention comprises a mixed air passage, so that the air in an area of the storage compartment with a relatively high temperature can enter the mixed air passage earlier than external air or the air in the storage compartment with a relatively low temperature. Then, the two air flows are blown to the storage compartment in a mixed manner, realizing even temperature distribution in the storage compartment.

    摘要： A cold end heat exchanging device (200) and a semiconductor refrigerator having the cold end heat exchanging device (200). The cold end heat exchanging device (200) comprises a cold end heat exchanging part (10) and a plurality of refrigeration agent pipelines (20). The cold end heat exchanging part (10) is used for limiting an inner cavity or a pipeline for containing a gas-phase and liquid-phase co-existing refrigeration agent. Each refrigeration agent pipeline (20) is provided with an evaporation section (21) that is downwards bent and extends in a vertical plane and has a sealed tail end, and a connection section (22) that is upwards bent and extends from a starting end of the evaporation section (21) and is communicated with the inner cavity or the pipeline. Evaporation sections (21) of at least some refrigeration agent pipelines (20) of the plurality of refrigeration agent pipelines (20) are distributed in two vertical planes that are perpendicular to each other. Because at least some evaporation sections (21) are distributed in the planes that are perpendicular to each other, at least one side wall and a rear wall of a liner can perform heat exchange with the evaporation sections, so that the cold radiation efficiency of the cold end heat exchanging device (200) and the energy efficiency of the semiconductor refrigerator are improved.

    摘要： A refrigerator control method and control system using a linear compressor. The control method comprises: detecting the ambient temperature T in the location of a refrigerator; comparing the ambient temperature T with a preset ambient temperature threshold T0; if T is greater than T0, controlling the cooling and/or heating components inside the refrigerator such that the refrigerator operates in a first working condition; if T is less than T0, controlling the refrigerator to operate in a second working condition; and when the linear compressor operates in a predetermined time, controlling the refrigerating quantity of the linear compressor in the second working condition to be greater than the refrigerating quantity of the linear compressor in the first working condition, such that the refrigerator reaches a target temperature. The present control method controls the operating state of a linear compressor by means of the cooling and/or heating components inside a refrigerator, increasing the strokes of the piston inside the linear compressor, and preventing the refrigerator from not functioning normally as a result of the linear compressor being protected by a frequency conversion plate.

    摘要： Disclosed is a refrigerator adopting a linear compressor and a control method thereof. The method includes: monitoring the temperature of an evaporator of the refrigerator; if the current temperature of the evaporator of the refrigerator is greater than or equal to a first preset temperature threshold, then invoking a noise reduction mode to actively reduce the heat exchange amount between the evaporator and a compartment of the refrigerator until the current temperature of the evaporator of the refrigerator is smaller than or equal to a second preset temperature threshold, and invoking a cooling mode to resume the normal heat exchange between the evaporator and the compartment of the refrigerator, wherein the first preset temperature threshold is higher than the second preset temperature threshold. In the present invention, when there is a heavy heating load, the air door of the evaporator and/or the blower is closed so that the heat exchange rate of the evaporator decreases, the temperature of the evaporator decreases rapidly, and the inlet and outlet pressures of the linear compressor also decrease accordingly. Finally, the entire vibration frequency of the linear compressor decreases, and is not easy to resonate with the refrigerator body, achieving the advantage of low operation noise.
