The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, solar energy transducer air conditioning of the present invention, comprise the air-conditioning unit of forming by indoor apparatus of air conditioner and off-premises station, be used to receive device with conversion solar bracket base 1, support 2 are arranged, be fixed on solar panel 3 on the support, be fixed on the battery 4 on the bracket base, also comprise light sensor 5, drive motors 6, output shaft, bearing block 7.Wherein, support 2 is that east-west direction is installed, and drive motors and output shaft are to make support towards helping most receiving the parts that sun direction of light is rotated, and we know that the irradiation of sunlight angle is different along with the difference of time.If solar panel is fixed on certain angle, along with the variation of sun irradiation angle, cell panel can't remain vertical with sunshine, makes conversion efficiency on the low side.Shortcoming at this fixed form cell panel, we utilize the resistance value of photoelectric cell (photo resistance) and the relation property of light intensity, and by pin resistance influence to the photo resistance on the diverse location under the sunray of different angles, the variation of angle between sunray and the plate face is changed into the variation of electrical quantities, by logical operation, be converted to the anglec of rotation output of support, drive motor is made respective reaction, guarantee that cell panel plate face is vertical with light all the time, reach the peak use rate of sunshine.
Fig. 2-4 shows the structure and the operation principle of light sensor 5, in the present invention, the structure of light sensor 5 is seen Fig. 2, comprise pedestal, perpendicular to the pin 9 of pedestal, lever is a plastics pin 9 cylindraceous, have on the pedestal on eight photo resistance 8, the pedestal and to also have two and install and fix hole 10, eight photo resistance 8 surround a circle, uniform distribution also is arranged on around the cylindrical plastic pin 9, install and fix hole 10 on the light sensor 5, light sensor and support can be fastenedly connected (see figure 1) by securing member.Light sensor 5 is answered sunshine by photo resistance 8 from innervation, when the resistance of photo resistance 8 changes, can give master control borad 21 signal feedback by microprocessor 22, the chip of master control borad 21 reads signal data and carries out logical operation, thereby intensity, the output signal of judging illumination make the drive motors that is arranged on solar panel one side drive output shaft and rotate, thereby the solar panel on the support is rotated towards the direction vertical with sunshine at east-west direction, realize function from the motion tracking sunshine.Referring to Fig. 3, be provided with a photodiode 11 in the cylindrical shape pin of light sensor, also install 11, two photodiodes of a photodiode at pedestal away from the place of lever and be connected with the master control borad communication, it offers master control borad and whether works as fore-stock at the signal of appropriate light according to the position.Circuit control principle referring to Fig. 4, microprocessor 22(model is L293) be connected with photosensitive resistor group 23 communications on the pedestal, photo resistance group 23 comprises that eight photo resistance 8(are referring to Fig. 2,3), when sunshine departs from the pin that certain angle is radiated at light sensor, photodiode 11 in the pin is blocked by lever because of light, amplifier is with output low level, then export high level at photodiode away from lever, the connection of two photodiodes is referring to the connecting circuit 24 of Fig. 4, when master control borad detects the level differences of two photodiodes, master control borad reads the resistance of eight photo resistance of microprocessor L293, and the difference of passing through resistance is judged the incident angle of sunray, output signal control output shaft rotates, realize the rotation of solar panel at east-west direction, solar panel of the present invention its in vertical direction rotational angle be 0 °-90 °.When night, two equal output low levels of photodiode are to the input of master control borad, and at this moment, master control borad control solar panel turns to original state, and promptly solar panel is on the angle perpendicular to the sunray in morning.
Fig. 5 and Fig. 6 are the structural representations of bearing block, bearing block 7 is made of pedestal and bearing body, pedestal is inlaid on the support, end at bearing body is provided with output shaft hole 71, be provided with and connect the through hole 72 of bearing body and output shaft hole in the wall portion of the corresponding output shaft hole of bearing body, the output shaft of drive motors 6 is inserted in the output shaft hole 71 of bearing block 7.One plane is arranged on the sidewall of output shaft, be provided with securing member in the through hole 72, flat head screw for example, the effect on the plane of output shaft sidewall is to make flat head screw make output shaft be pressed in the output shaft hole 71 by compressing this plane, output shaft can not trackslip in output shaft hole, thereby makes, when drive motors orders about the output shaft rotation, bearing block rotates synchronously, rotates thereby drive support.
Required input power is generally about 400W during the operation of the convertible frequency air-conditioner of split type high energy efficiency, and polysilicon solar cell plate generated energy under sunshine good situation is 140W/M
2, therefore when polysilicon solar cell plate gauge lattice be that 3M(is long) X1M(is wide)=3 M
2, exportable power cooperates this automatic solar energy tracking device about 420W, can satisfy convertible frequency air-conditioner operation power demand, and promptly the required electric energy of air-conditioning is all provided by the collected conversion of solar energy of polysilicon solar cell plate, reaches design object.
This solar energy transducer air conditioning has also designed energy-storage function, stationary stroage battery 4 on bracket base, battery provides electric energy for drive motors on the one hand, when there be not illumination evening, master control borad need be controlled support and reset to original position, waits for the irradiation of second day sun, at this moment, the electric weight that stores in the battery uses for drive motors, finishes the process of Program reset.On the other hand, battery is as energy storage device, when can store unnecessary electric weight and be used for night or do not have solar irradiation.
The power subsystem of air-conditioner connects solar panel and civil power, whether air conditioner control system is sufficient by the electric weight that power-sensing circuit, maximal power tracing circuit (MPPT) detect conversion of solar energy under different time and the environment, and the inadequate part of solar energy electric weight is then replenished by electrical network.When controller receive the user close the signal of air-conditioner after and detect this moment during solar panels generated energy foot, controller sends instruction, cuts off the total civil power incoming line of family, switches to solar powered incoming line, for user's household provides free electric energy.And if to evening detect reserve of electricity when sufficient system can cut off civil power automatically and use the battery electric energy, system can change back civil power automatically and uses for air-conditioning when electric weight is not enough.
The present invention has improved the conversion ratio of solar energy greatly, provides more convenience and interests to the user, and whole electrical system need not with electrical network concurrently, and the generation of having stopped island effect has strengthened its reliability greatly.So the The whole control device has high efficiency, low cost, advantage such as compatible strong.Satisfy the versatility demand of machine seriesization, but provide method easily for regular solar convertible frequency air-conditioner upgrading becomes the tracking solar convertible frequency air-conditioner.Along with being rooted in the hearts of the people of energy-saving and emission-reduction and low-carbon (LC) life, this new type solar energy convertible frequency air-conditioner will become the main product of following domestic variable frequency air-conditioning surely.
