Description

Technical Field

[0001] The invention relates to the technical field of two-stage compressors, and in particular to a two-stage compressor and an air conditioning unit for a mushroom cabin. Background Art

[0002] In the prior art, centrifuges for refrigeration often use one-stage compression and two-stage compression. In the commonly used refrigeration range, such as 12 / 7℃ for chilled water inlet and outlet, and 30 / 35℃ for cooling water inlet and outlet, the pressure ratio is not high at this water temperature, so one-stage compression and two-stage compression units are more widely used. When the chilled water inlet and outlet temperature remains unchanged at 12 / 7℃, and the cooling water outlet temperature is relatively high, such as 70℃ outlet, the unit requires a pressure ratio of up to 6.5, which is exactly what most industrial manufacturing equipment and heating and heat exchange fields need.

[0003] In order to improve the pressure ratio of centrifugal compressors, for single-stage compressors, the common practice is to increase the shape design of the impeller or increase the impeller speed so that the impeller can obtain more energy, thereby increasing the pressure ratio. Generally speaking, in order to ensure the safe and reliable operation of the impeller, the circumferential speed of the impeller outlet is not more than 300m / s. However, in order to obtain a higher pressure ratio, the outer diameter of the impeller has to be increased or the speed has to be increased, which conflicts with the strength of the material itself. If the outer dimensions of the impeller are kept unchanged and the speed is increased, it is very likely that the speed of the rotating parts will approach or reach the inherent critical speed and resonance will occur. At this time, if the fan blades collide with impurities and debris in the air, the device is very likely to be damaged, affecting the reliable operation of the compressor and the unit.

[0004] Therefore, it is necessary to provide a two-stage compressor and air conditioning unit for a mushroom cabin to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0006] Based on the above-mentioned problems existing in the prior art, the problem to be solved by the present application is: in order to improve the pressure ratio of the centrifugal compressor, for a single-stage compressor, a common practice is to increase the shape design of the impeller or increase the impeller speed, so that the impeller can obtain more energy, thereby improving the pressure ratio.

If the outer dimensions of the impeller are kept unchanged and achieved by increasing the speed, it is very likely that the speed of the rotating parts will approach or reach the inherent critical speed and resonance will occur. At this time, if the fan blades collide with impurities and debris in the air, the device is very likely to be damaged, affecting the reliable operation of the compressor and the unit.
