Magnetic suspension turbocharging device of refrigeration machine

Abstract

The invention discloses a magnetic suspension turbo charging device used on a refrigerating machine. The turbo charging device comprises a low-pressure turbine component, a bearing component and a driving component; the low-pressure turbine component is arranged at one side of the bearing component, while the driving component is arranged at the other side of the bearing component; a turboshaft is arranged at the center of the inner side of the bearing component, the two ends along the axial direction extend into the inner sides of the low-pressure turbine component and the driving component and are connected with the rotating components arranged at the inner side of the low-pressure turbine component and the driving component. By utilizing the exhaust of the refrigeration system or the drive of external force, the invention increases the air transmission quantity of the compressor, effectively increases the circulating amount of the cooling medium, reduces the running friction of the motor and improves the refrigerating output and electrical efficiency of the refrigerating machine.

Description

technical field [0001] The invention relates to a magnetic suspension turbocharging device for a refrigerator. Background technique [0002] At present, when a common vapor compression refrigerator performs a refrigeration cycle, the refrigerant evaporates and is inhaled by the compressor in a gaseous state, then enters the heat exchanger after being compressed, and then passes through a throttling device or an expander (usually a constant flow throttling mechanism) (such as capillary) mostly to achieve refrigeration) to complete the cycle. In this way, the refrigerant generally enters the compressor in a superheated state, and the volume of the refrigerant expands greatly, that is, the specific volume increases, so that the quality of the refrigerant that actually participates in the refrigeration cycle is relatively reduced; on the premise that the input power of the compressor is determined, the compression In order to achieve refrigeration, the machine must ensure a cer...

In this way, the refrigerant generally enters the compressor in a superheated state, and the volume of the refrigerant expands greatly, that is, the specific volume increases, so that the quality of the refrigerant that actually participates in the refrigeration cycle is relatively reduced; on the premise that the input power of the compressor is determined, the compression In order to achieve refrigeration, the machine must ensure a certain compression ratio, so the air transmission volume of the refrigeration system becomes smaller. At the same time, there is friction between the compressor shaft and the support bearing during operation, and the input power of the motor is small, and the compressor heats up. The capacity is reduced, and when the working environment of the compressor is bad, the efficiency of the refrigeration equipment is extremely low, and even cannot be used normally
