Problems solved by technology
Although the method adopted in the prior art reduces the intersection of two loads and becomes an independent control part, so that it will not stop due to a fault signal, it increases the same equipment in the air-conditioning system and increases the cost; at the same time, the air-conditioning When the system is idle, the energy generated by the wind to rotate the fan is not effectively recycled, resulting in a waste of available resources

Embodiment Construction
[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0025] Such as figure 1 As shown, the first embodiment of the air conditioning system according to the present invention includes a fan 10 and a compressor 20. The air conditioning system also includes a DC bus and a main compressor converter 30 connected to the DC bus. The main The compressor converter 30 is drivingly connected to the fan 10 and the compressor 20 ; wherein, the main compressor converter 30 has an inverter state for driving the compressor 20 and the fan 10 and a rectification state for recovering the electric energy generated by the fan 10 .
[0026] In the first embodiment, by making the main compressor inverter 30 simultaneously drive the fan 10 and the compressor 20, compared with the prior art, one fan inverter and the corresponding driving mechanism are reduced, and the cost is reduced; in addition , when the air conditioning system ...

The invention provides an air conditioning system, which comprises at least one draught fan and at least one compressor, and further comprises a direct current bus and at least one main press converter connected to the direct current bus, wherein each main press converter is in drive connection with at least one in the at least one draught fan and at least one in the at least one compressor; the main press converter is provided with an inverter state for driving the compressor and the draught fan and a rectification state for recycling the power generation electric energy of the draught fan. According to the air conditioning system, each main press converter synchronously drives at least one draught fan and at least one compressor, so that the same setting in the air conditioning system is effectively reduced and the cost is reduced; in addition, when the air conditioning system works, the main press converter works in the inverter state and drives the compressor and the draught fan to work; when the air conditioning system stops, the main press converter works in the rectification state under the condition that the draught fan is driven to generate electricity by wind, so that the electric energy is recycled.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioning system. Background technique [0002] Creating green products has become the demand of enterprises based on development. In the field of air conditioning, it is also catering to the "green" and gradually moving towards the frequency conversion era. At present, due to the strong structure, small size, high air gap flux density, high power and high The moment of inertia ratio and many other advantages are widely used in compressors / fans. In the prior art, due to the difference in speed, power and load properties of compressors and fans, different converters and different drive controllers are required. , the size of the cooling power of the fan needs to be programmed to match. Although the method adopted in the prior art reduces the intersection of two loads and becomes an independent control part so that it will not stop due to a fault signal, it increases the ...
