Detailed description of the invention
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, according to air-conditioning system first embodiment of the present utility model, comprise Fans 10, compressor 20, air-conditioning system also comprises dc bus and is connected to a main press transverter 30 on dc bus, and main press transverter 30 drives with blower fan 10 and compressor 20 and is connected; Wherein, main press transverter 30 has to drive the inverter mode of compressor 20 and blower fan 10 and reclaim blower fan 10 and to generate electricity the rectification state of electric energy.
In a first embodiment, by making main press transverter 30 drive blower fan 10 and compressor 20 simultaneously, compared to existing technology, decrease a Fans transverter and corresponding driving mechanism, reduce cost; In addition, when air-conditioning system works, main press transverter 30 is operated in inverter mode, drives compressor 20 and blower fan 10 to work; When air-conditioning system stops, when blower fan 10 is driven generating by wind, main press transverter 30 is operated in rectification state, thus reclaims electric energy.Namely, when air-conditioning system does not work, blower fan becomes a generator, thus makes air-conditioning system more energy-conservation.
Particularly, because main press transverter 30 drives blower fan 10 and compressor 20 simultaneously, thus can simultaneously lifting frequency, acting coupling.For air-conditioning work under refrigerating state, in raising frequency process, blower fan 10 and compressor 20 can synchronously increase speed, comparatively meet refrigerating capacity large time, compressor work is large, condenser heat exchange amount large, and rotation speed of fan is high simultaneously, heat dissipation capacity is large; Correspondingly, when frequency reducing, blower fan 10 and compressor 20 synchronously can reduce rotating speed, comparatively meet refrigerating capacity hour, and compressor work is little, condenser heat exchange amount is little, and rotation speed of fan is low simultaneously, heat dissipation capacity is little.
When air-conditioning system is left unused, if any wind, blower fan 10 is rotated, then use this main press transverter 30 shared to carry out reverse rectification and obtain direct current, in the presence of a harsh environment, because main press transverter 30 power grade is high, the possibility causing generating to damage is little.
Preferably, air-conditioning system can also arrange battery, and battery is connected with main press transverter 30 (or dc bus), in blower fan 10 power generation process, by power storage, when blower fan normally works, battery provides a part of electric energy to work for blower fan 10.
Further, air-conditioning system can also comprise grid-connected transverter 50, and the first end of grid-connected transverter 50 is connected with electrical network 60, and the second end of grid-connected transverter 50 is connected with dc bus.Namely blower fan 10 generate electricity namely can by the equipment such as battery store, also carry out grid-connected other loads of supply electrical network by grid-connected transverter 50.Usually, grid-connected transverter 50 and main press transverter 30 are four-quadrant transverter.
Preferably, air-conditioning system also comprises isolating transformer 70, and isolating transformer 70 is connected between electrical network 60 and grid-connected transverter 50, and series connection isolating transformer 70 can improve the security of air-conditioning system, also can prevent interference.
Composition graphs 1 illustrates the operation principle of air-conditioning system of the present utility model.The relatively common convertible frequency air-conditioner of air-conditioning system of the first embodiment, cancel fan converter and driving governor thereof, blower fan 10 is directly connected on main press transverter 30, by choosing or the use of reduction gearing blower fan 10 motor number of pole-pairs, control the rotating speed of blower fan 10, needed for coupling air-conditioning, heat dissipation capacity and blower fan 10 provide heat exchange amount.When air-conditioning system works, main press transverter 30 is operated in DC-AC inverter mode, blower fan 10 rotates and dispels the heat to the outer machine of air-conditioning system, now, use the blower fan number of pole-pairs of determining ratio, match compressor 20, blower fan 10 rotating speed, if when compressor 20 raising frequency loads, heat dissipation capacity needed for air-conditioning system is large, the also corresponding raising of blower fan 10 rotating speed, and heat exchange amount also strengthens; If during compressor 20 frequency reducing off-load, needed for air-conditioning system, heat dissipation capacity is little, the also corresponding reduction of blower fan 10 rotating speed, heat exchange amount also reduces.Also can pass through size gear mechanism Dynamic controlling, make it to meet heat dissipation capacity needed for air-conditioning and provide mating of heat exchange amount with blower fan.
When air-conditioning system does not work, blower fan forms wind-driven generator in conjunction with main press transverter 30 equipment, and when the wind comes from wheel rotation, main press transverter 30 is operated in AC-DC rectification state, thus generating.Generating can be grid-connected by electric energy by grid-connected transverter 50, also can by other DC-DC equipment other equipment use to battery energy storage, supply direct current.Thus reach the object of wind energy recycling.
Due to the main press transverter 30 of compressor 20 used, large than existing fan converter power capacity, so under atrocious weather high wind speed, also can generate electricity reliably.In Double Motor Control process, basic opened loop control can be used, realize the operation of bi-motor; Also the parameter of electric machine can be used as compressor, the blower fan of the geometric ratio such as sensibility reciprocal, resistance.When VFC, because blower fan 10 power is less relative to compressor 20 power, (power of blower fan 10 is generally tens several hectowatts, compressor horsepower is generally tens kilowatts), when closed-loop adjustment, only feed back compressor 20 current parameters and do decoupling zero related algorithm, consider by blower fan current parameters when consume adds, thus make system stable operation.
In the second embodiment as shown in Figure 2, compare the first embodiment, in the second embodiment, blower fan 10 is two, and namely a main press transverter 30 drives compressor 20 and two Fans 10 simultaneously, thus realizes reducing blower fan transverter, the effect reduced costs.Meanwhile, be similar to the first embodiment, can choosing or the use of reduction gearing blower fan 10 motor number of pole-pairs, realize the rotating speed coupling of compressor 20 and blower fan 10.Also grid-connected device such as transverter 50 grade can be set correspondence, reclaim the electric energy of blower fan generating, and by blower fan electricity generation grid-connecting, thus make air-conditioning system have band wind power generation function.
In the 3rd embodiment as shown in Figure 3, compare the second embodiment, in the 3rd embodiment, blower fan 10 is multiple stage, and namely a main press transverter 30 drives a compressor 20 and multiple stage blower fan 10 simultaneously, thus realizes reducing blower fan transverter, the effect reduced costs.Other controls are similar to the first embodiment and the second embodiment, do not repeat them here.
