Air Conditioning System

Abstract

An air conditioner system includes at least one fan (10) and at least one compressor (20), and further includes a direct current bus and at least one main press machine converter (30) connected thereto. Each main press machine converter (30) is in drive connection with at least one in the at least one fan (10) and at least one in the at least one compressor (20). The main press machine converter (30) has an inverter state for driving the compressor (20) and the fan (10) and a rectification state for recycling the electric energy generated by the fan (10). According to the air conditioner system, each main press machine converter (30) synchronously drives at least one fan (10) and at least one compressor (20), so that the same setting in the system is effectively reduced and the cost is reduced. In addition, when the air conditioner system works, the main press machine converter (30) works in the inverter state and drives the compressor (20) and the fan (10) to dissipate the heat of the air conditioner system; when the air conditioner system stops, the main machine converter (30) works in the rectification state under the condition that the fan (10) is driven to generate power 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 ...

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
