Description

Technical Field

[0001] The utility model relates to the technical field of plastic manufacturing, in particular to an air-cooled screw chiller. Background Art

[0002] The air-cooled screw chiller is named screw chiller because its key component - the compressor adopts screw type. The unit is composed of gas refrigerant in the state of coming out of the evaporator; after adiabatic compression by the compressor, it becomes a high-temperature and high-pressure state. The compressed gas refrigerant is cooled and condensed at equal pressure in the condenser, and changes into liquid refrigerant after condensation, and then expands to low pressure through the throttle valve to become a gas-liquid mixture. Among them, the liquid refrigerant at low temperature and low pressure absorbs the heat of the cooled substance in the evaporator and turns into gas refrigerant again. The gas refrigerant re-enters the compressor through the pipeline and starts a new cycle. These are the four processes of the refrigeration cycle, which is also the main working principle of the screw chiller.

[0003] When the existing air-cooled screw chiller is in use, its external protective shell is mostly fixed by bolts. Therefore, it is not convenient to open it during maintenance, which makes it not very convenient to maintain. At the same time, a large amount of dust will accumulate on the top of the inner cavity of the device, which mostly needs to be cleaned manually. Utility Model Content
