The flow and pressure detection module and the temperature detection sensor which are arranged among pipelines of the integrated air compressor system can be used for automatically adjusting the flow and power of the system operation.

Because the main drive adopts the integrated rare earth motor module 1, a variable frequency control module is needed for starting. Compared with the traditional asynchronous motor, the rare earth permanent magnet motor rotor main shaft 104 of the integrated rare earth motor module 1 is formed by alternately embedding rare earth permanent magnet materials according to different magnetic poles, does not need exciting current, and therefore has smaller power consumption and temperature rise. During operation, the integrated rare earth motor module 1 serves as a power source to drive the four-rod type spiral air compressor module 2 and the scroll refrigerant compressor module 4 simultaneously, and compressed air output and refrigerant compression circulation are completed respectively. Wherein the pipelines of the compressed air and the refrigerant converge to the cooling and drying integrated module 3, and the compressed air is cooled and dried, and the low-temperature dried compressed air is cooled and cooled by the internal air loop of the integrated rare earth motor module 1.

Further, the refrigerant is delivered to the refrigerant heat exchange module 604 in the heat exchange centralized control module 6 through the refrigerant outlet 411 and the refrigerant compression output pipe 410, and the air flow generated by the heat exchange fan 603 dissipates heat and reduces temperature of the refrigerant.

Further, the high-pressure refrigerant having a reduced temperature flows back to the above expansion valve 5 via a pipe to become a low-pressure gas, and the temperature suddenly drops due to the pressure reduction.

Further, the low-temperature refrigerant enters the heat exchange circuit module 301 in the cooling and drying integrated module 3 through the refrigerant output pipe 304, absorbs the heat of the compressed air, and is heated again. And re-enters the refrigerant compression tank 409 of the scroll refrigerant compressor module 4 through the refrigerant inlet pipe 305, and is compressed by the relative movement of the orbiting scroll 407 with respect to the fixed scroll 406.

According to the system requirement and the data fed back by the temperature sensor, the intelligent control development board can control the switch of any one of the cooling and drying integrated modules 3, thereby adjusting the refrigerant circulation flow and the temperature of the refrigerant output.

A compressed air output section:

further, the rare earth permanent magnet motor rotor main shaft 104 drives the driving screw 211 to rotate through the coupler 217.

Further, the driven screw gear 206 attached to the driven screw 212 is driven to rotate by a driving screw gear 208 attached to the driving screw 211. Thereby causing the driving screw 211 to rotate in opposition to any one of the three driven screws 212.

Further, air enters between the main screw chamber 221 and the sub screw chamber 222 through the 3 total air inlets 201 of the compressor base 202, and is spirally compressed into compressed air by the driving screw 211 and the driven screw 212.

Further, compared with a traditional double-spiral air compressor, the effective compression volume of the double-spiral air compressor is only the overlapping part between 2 spiral rods. And the utility model discloses a 4 pole helical structure, the volume that utilizes 2 times has produced 3 times transmission air compressor's effective compression volume. The compression efficiency is enlarged by 1.5 times, and the effect of generating larger compression flow with smaller volume is achieved.

Further, according to the system requirement, the intelligent control development board may control the switch of any one of the 3 main air inlets 201, so as to control the flow rate of the intake air.

Further, according to the system requirement, the intelligent control development board may control any one of the 3 spiral compression output ports 220 to be switched on and off, so as to control the air outlet flow rate and the air outlet pressure.

Cooling and drying part:

further, the compressed air enters 3 sets of the cooling and drying integrated modules 3 through 3 compressed air output pipes 216, respectively. The low-temperature refrigerant enters 3 sets of the cooling and drying integrated modules 3 through 3 refrigerant output pipes 304.

Further, the compressed air and the refrigerant pass through different cabins and pipelines of the cooling and drying integrated module 3, and the compressed air is cooled by the low-temperature refrigerant.

Further, since the dew point temperature of the compressed air is lowered, moisture is easily separated out with the lowering of the temperature, and the compressed air becomes dry. The compressed air is cooled by the refrigerant, water is separated out and is discharged by a drain valve, and cooling and drying of the compressed air are completed.

The motor cooling protection part:

further, the low-temperature dried compressed air enters the stator cooling air passage 107 of the rare earth permanent magnet motor stator 106 through the dried cooling air output pipe 303. The temperature of the integrated rare earth motor module 1 during operation is reduced, and the temperature is prevented from being excessively increased.

Further, the compressed air is output from the compressed air main outlet 101 and supplied to the pneumatic equipment for use.
