Description
Technical field
The utility model relates to a kind of solar-powered refrigerator.
Background technology
At present, the solar energy refrigerator of Chu Xianing mainly is two kinds of forms on the market: (1) is made up of single absorption system, its inside does not have compressor, utilize solar energy direct irradiation absorption system (mostly being the ammoniacal liquor circulatory system greatly) to make its running reach refrigeration, the defective that this structure exists is: poor refrigerating efficiency, generally can only reach 0 ℃, can not reach lower temperature; In the situation (for example overcast and rainy cloudy weather) of sunlight deficiency and do not have night under the situation of sunlight, can bring inconvenience to the user because the solar absorption deficiency making refrigerator normally not use.(2) by solar panel, inverter, alternating current compression machine is formed, absorb solar energy by solar panel and convert electric energy (this moment, voltage was lower) to, power supply makes its running reach refrigeration to alternating current compression machine through inverter voltage to be risen to the 220V alternating current again, this structure can reach very low temperature, refrigeration is better, but need use inverter boosts, use energy consumption in the process of boosting is bigger, the stored electric energy of solar panel will soon use up, therefore the normal time of using of refrigerator is shorter, in addition, the working voltage of this structure is higher, has certain potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of solar-powered refrigerator, and refrigeration is better, and working voltage is lower, and security is higher.
For achieving the above object, the technical solution of the utility model is:
A kind of solar-powered refrigerator comprises refrigerator, also comprises photoelectric conversion device, solar storage battery, 12V/24V direct current compressor,
Described photoelectric conversion device is used for converting solar energy to electric energy, the input of described solar storage battery is connected with the output of photoelectric conversion device, the output of described solar storage battery is connected with the input of 12V/24V direct current compressor, and the output of described 12V/24V direct current compressor is connected with refrigerator.
Operation principle of the present utility model is: photoelectric conversion device absorbs solar energy and also converts thereof into electric energy, then with electrical power storage in solar storage battery, solar storage battery makes its running reach refrigeration for the power supply of 12V/24V direct current compressor.
Preferably, photoelectric conversion device described in the utility model is a solar panel.
The utility model can be done further improvement, and described solar-powered refrigerator also comprises charge controller, and described photoelectric conversion device is connected in described solar storage battery by charge controller.
Therefore compared with prior art, the utility model has following beneficial effect:
(1) the 12V/24V direct current compressor refrigeration in the utility model is better, can reach 18 degrees below zero, and uses the 12V/24V direct current just can operate, make refrigerator can directly use the low-voltage electric energy of solar storage battery, do not need to boost, energy consumption is lower, and security is higher;
(2) solar storage battery in the utility model can store the electric energy that solar panel is changed, guarantee that refrigerator is in the situation (for example overcast and rainy cloudy weather) of sunlight deficiency and do not have night still can normally use under the situation of sunlight, be applicable to that field etc. does not have the place of electricity, very convenient.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Be illustrated in figure 1 as the embodiment of a kind of solar-powered refrigerator described in the utility model, a kind of solar-powered refrigerator, comprise refrigerator 6, also comprise photoelectric conversion device 1, solar storage battery 4,12V/24V direct current compressor 5, photoelectric conversion device 1 is used for converting solar energy to electric energy, the input of solar storage battery 4 is connected with the output of photoelectric conversion device 1, the output of solar storage battery 4 is connected with the input of 12V/24V direct current compressor 5, and the output of 12V/24V direct current compressor 5 is connected with refrigerator 6.
Operation principle is: photoelectric conversion device 1 absorbs solar energy and also converts thereof into electric energy, then with electrical power storage in solar storage battery 4, the low-voltage electric energy of solar storage battery 4 makes its running reach refrigeration directly for 5 power supplies of 12V/24V direct current compressor.
In order to improve energy conversion efficiency, in the present embodiment, photoelectric conversion device 1 is a solar panel.
For more convenient use, present embodiment also comprises charge controller 3, and photoelectric conversion device 1 is connected in solar storage battery 4 by charge controller 3, and charge controller 3 can be controlled the work of solar storage battery 4.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
