Abstract

This invention is to increase a floor area ratio of a freezing chamber and a utilization rate of heat transfer. A refrigerator is disclosed, which includes a cabinet having a storage space, a mullion provided in the cabinet to divide the storage space into a freezing chamber and a refrigerator chamber, the mullion having a cold airflow passage provided therein that is communicated with the freezing chamber and the refrigerator chamber, a double suction centrifugal blower provided in a middle space of the mullion and sucking air from the freezing chamber and the refrigerator chamber and exhausting to the cold airflow passage, an evaporator provided in the cold airflow passage for exchanging heat with the air exhausted from the double suction centrifugal blower, a top outlet and a bottom outlet exhausting air being passed through the evaporator to the freezing chamber and the refrigerator chamber.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator using a double-suction centrifugal fan. Background technique [0002] Generally, a refrigerator is a device that can keep stored food fresh for a long time. Such as figure 1 The illustrated refrigerator includes an evaporation chamber 3 having a cabinet 1, a frame 2, an evaporator 3a, and a fan 3b, and an equipment room accommodating refrigerant pipes, a compressor, and a condenser. [0003] The composition of the refrigerator is explained below, and there is a storage space in the cabinet 1 . The frame 2 divides the storage space in the box into a freezer compartment 1a and a refrigerator compartment 1b. There is a cold air passage on the frame 2, which can make the refrigerant flow between the freezing chamber 1a and the refrigerating chamber 1b. The refrigerant pipe 4 connected to the cold air passage 2a transmits the refrigerant to each part of the refrigerating chamber 1b...
