Abstract
The invention discloses solar refrigeration equipment which comprises a solar power generation system. The solar power generation system is connected with an inverter and a charger, the charger is connected with the inverter and a storage battery, the storage battery is connected with the inverter which is connected with a frequency changer, and the frequency changer is connected with a compressor. The frequency changer is added between the inverter and the compressor, when the 3 KW compressor is started, only a 5 KW solar photovoltaic panel is needed, the number of solar photovoltaic panels is greatly reduced, and redundant electric energy can charge the storage battery, cost is reduced, and energy sources are saved. The frequency changer is adopted to reduce the starting current of the compressor, power of the solar photovoltaic panel and the power of the inverter are reduced, the inverter is protected, and the service life of the inverter is prolonged.
Description
Technical field
The present invention relates to a kind of refrigeration plant, particularly solar refrigeration equipment.
Background technology
At present, solar refrigeration equipment mainly directly starts compressor by inverter, the compressor that the solar energy photovoltaic panel ability starting power of general required power more than 10KW is 3KW, cost is larger, and because the electric current of compressor start is larger, will affect the useful life of inverter, solar energy photovoltaic panel does not have unnecessary electric weight to charge a battery, storage battery needs charging in addition to use, and energy resource consumption is large.
Summary of the invention
The object of the invention is in order to overcome above deficiency, the solar refrigeration equipment of a kind of simple in structure, cost, long service life is provided.
Object of the present invention is achieved through the following technical solutions: a kind of solar refrigeration equipment, comprise solar power system, solar power system is connected with charger with inverter, charger is connected with storage battery with inverter, storage battery is connected with inverter, inverter is connected with frequency converter, and frequency converter is connected with compressor.
Further improvement of the present invention is: solar power system is solar energy photovoltaic panel.
Further improvement of the present invention is: frequency converter is unit cascade type frequency converter.
The present invention compared with prior art has advantages of: the present invention has increased frequency converter between inverter and compressor, in the time starting the compressor of 3KW, only need like this solar energy photovoltaic panel of 5KW, greatly reduce the quantity of solar energy photovoltaic panel, and also have unnecessary electric weight to charge a battery, not only reduce cost, also saved the energy; The present invention adopts frequency converter to reduce the starting current of compressor, has reduced the power of solar energy photovoltaic panel, inverter, and protection inverter has increased useful life of inverter.
brief description of the drawings:
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-solar power system, 2-inverter, 3-charger, 4-storage battery, 5-frequency converter, 6-compressor.
embodiment:
in order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 shows a kind of execution mode of a kind of solar refrigeration equipment of the present invention, comprise solar power system 1, solar power system 1 is solar energy photovoltaic panel, solar power system 1 is connected with charger 3 with inverter 2, charger 3 is connected with storage battery 4 with inverter 2, and storage battery 4 is connected with inverter 2, and inverter 2 is connected with frequency converter 5, frequency converter 5 is unit cascade type frequency converter, and frequency converter 5 is connected with compressor 6.
Solar energy photovoltaic panel is by electrical transmission to inverter and charger, and charger charges a battery, and also can give inverter power supply simultaneously, and storage battery also can be given inverter power supply, and inverter is by electrical transmission to frequency converter, and frequency converter starts compressor.The present invention has increased frequency converter between inverter and compressor, the solar energy photovoltaic panel that only needs like this 5KW in the time starting the compressor of 3KW, has greatly reduced the quantity of solar energy photovoltaic panel, and has also had unnecessary electric weight to charge a battery, not only reduce cost, also saved the energy; The present invention adopts frequency converter to reduce the starting current of compressor, has reduced the power of solar energy photovoltaic panel, inverter, and protection inverter has increased useful life of inverter.
