A refrigerator is provided. The refrigerator includes a main cabinet including a cooling device to generate cold air, a sub-cabinet detachably connected to the main cabinet, a cold air relay duct provided to connect the main cabinet and the sub-cabinet and having a cold air flow path to allow the cold air generated by the cooling device to be delivered to the sub-cabinet, and a heat blocking member provided in a portion of the cold air flow path at which the main cabinet and the cold air relay duct are connected and in a portion of the cold air flow path at which the sub-cabinet and the cold air relay duct are connected.

Refrigerator

A refrigerator is provided. The refrigerator includes a plurality of refrigerant flow paths, configured to reduce the drift of the refrigerant. The refrigerator includes a refrigeration cycle including a compressor, a condenser, a plurality of refrigerant flow paths branched at a downstream of the condenser, the plurality of refrigerant flow paths each including a pressure reducing device, and an evaporator connected to the plurality of refrigerant flow paths, and a processor including a switching valve configured to individually switch an open or closed state of each of the plurality of refrigerant flow paths, the processor being configured to adjust a flow rate of refrigerant flowing in each of the plurality of refrigerant flow paths by individually duty-controlling an opening and closing time of each of the plurality of refrigerant flow paths by controlling the switching valve.

A refrigeratorcomprises at least one box-shaped storage compartmentand a heat radiating member. The storage compartmentis formed in such a way that one side of a frame formed by a wall member is closed and the other thereof is provided with an opening surface configured to be opened or closed by a door. The wall member includes a hollow structure composed of a plurality of plate membersandand a foam insulationfilled in the hollow structure. The heat radiating memberis arranged in the wall member. In the wall member, a pressure memberconfigured to press the heat radiating member against the plate member is provided. The pressure memberis a material configured to press the heat radiating memberunder predetermined conditions.

The present invention provides precise temperature control of a cooling chamber and comprises: a cooling chamber; a refrigeration circuit having a compressor, a condenser installed at the outlet side of the compressor, an evaporator, installed between the outlet side of the condenser and the inlet side of the compressor, for cooling the cooling chamber, and a decompression means installed at the inlet side of the evaporator; and a refrigerant control unit which has a refrigerant control valve installed between the condenser and the evaporator, and which adjusts the refrigerant flow rate that flows into the evaporator by controlling the opening/closing time of the refrigerant control valve.
