The Development Of Solar Refrigerators Jun 28, 2017


The use of traditional refrigerators need to consume a lot of conventional energy, indirect pollution caused by the environment more and more serious. From China's current energy supply situation and environmental protection needs, the development of the use of clean energy refrigerator will be the trend. In addition, there are many remote areas and nomads in China has not yet been included in the power supply network, Solar Freezer and Refrigerator there is no condition to use the refrigerator to save food, which also for the development of solar refrigerators to provide a potential market.

However, there are various factors at this stage to limit the wide range of solar refrigerator technology. On the one hand, due to the low efficiency of solar energy, high prices, and by the aging effect, for the relative concentration of residential buildings, the installation of the collector will be greatly limited; the other hand, solar refrigeration in many forms, but The status quo of the study, Solar Freezer and Refrigerator a variety of different forms of refrigeration systems are inadequate. How to further improve the operating efficiency of the system and the joint operation of various refrigeration cycles are the focus of future research areas. With the development of new materials and new technologies needed by solar refrigerator system design, the research and application of solar energy in refrigerator refrigeration will be greatly developed under the support of government energy saving and environmental protection and home appliances.

The current consumption of a large number of electric power to drive the traditional refrigerator technology has been maturing, simply from the efficient, energy saving, Solar Freezer and Refrigerator energy saving aspects of the refrigerator technology innovation is difficult to have a big breakthrough, but the solar refrigerator there is a big room for development, will be the future A development direction of the refrigerator industry. The development of solar refrigerator is a major innovation in the refrigerator industry, for the entire refrigerator industry chain to upgrade the technology has a huge role in promoting, and for environmental protection, energy conservation and so make a significant contribution.

As the internal structure of solar refrigerators and traditional refrigerator the same, but the power supply device to solar cells, so it is relatively simple to achieve. Foreign literature reports show that many experimental results show that the traditional exchange of refrigerators into a photovoltaic system for the DC refrigerator, the components can be normal operation, the refrigerator can work properly. In the country, Solar Freezer and Refrigerator for solar photovoltaic refrigeration refrigerator research is also a lot, and some progress. "Solar Energy Journal" in 2007 reported Liu Qunsheng and other photovoltaic DC refrigerator system running performance research results, the system's only power source for the solar energy, the use of DC compressors, the system is equipped with batteries. The experimental results show that the minimum temperature of the refrigerator freezer can reach -16 ℃, Solar Freezer and Refrigerator the refrigerating compartment can reach 0 ~ 10 ℃, the operating rate is 48% when working at 25 ℃ ambient temperature. As early as 1997, Huang Fulin will be the new all-digital SPWM modulation applied to the solar photovoltaic refrigerator frequency conversion circuit, and to achieve the refrigerator temperature control.

In the field of solar semiconductor refrigerator research, Gansu Natural Energy Research Institute Zou Jinping and Luo Bin, etc., have written the introduction of solar cell-driven semiconductor refrigeration refrigerator system, the basic structure of the establishment of a solar cell-driven semiconductor refrigerator theoretical model, and the system The effects of solar radiation intensity and ambient wind speed on the performance of solar semiconductor refrigeration system were analyzed.
