- At present, the main equipment inside the compressor compartment mainly comprises a compressor, a condenser, a condenser fan, generally, the condenser is a tube-and-fin type. As the energy source of the whole refrigeration system, the compressor compresses a low-temperature and low-pressure refrigerant into a high-temperature and high-pressure superheated air by the movement of a rotational mechanical action, a large amount of heat is generated in this process. The high-temperature and high-pressure refrigerant superheated air is discharged from an outlet of the compressor, entered into the condenser and subjected to forced air convection heat exchange with the surrounding air by means of a condensing fan. In such a narrow space, the heat exchanging efficiency of the compressor and the condenser directly affect the refrigeration performance of the entire refrigerator system. At the same time, both the compressor and the condensing fan are rotating machines that generate noise during operation, wherein the compressor mainly generates vibration noise and the condensing fan mainly generates pneumatic noise. The noise level of the compressor and condensing fan will directly affect the noise performance of the whole machine.
- Due to the limited space, the existing refrigerator products have problems of insufficient heat dissipation capacity and high noise level:
There is a problem with the heat dissipation of the compressor. Due to the influence of the spatial layout and the air-flow field, on a leeward side of the compressor, the amount of heat carried by the air is reduced due to a reduced flow rate, thus the heat cannot be effectively dissipated. - There is a problem in the heat dissipation of the condenser. Due to the limited space and the structure of the condenser itself, when the air flows through the condenser, the air resistance is large, the flow rate is lowered, the heat dissipation performance is reduced.
- The compressor generates vibration noise when compressing the refrigerant from a low-temperature and a low-pressure state to a high-temperature and a high-pressure state by means of a rotating structure, which is the main source of refrigerator noise and seriously affects the noise performance of the refrigerator.
- The flow is lost due to a portion of the air flowing through the space below the condenser.
