Prospects for the development of solar refrigerators
Prospects for the development of solar refrigerators
The use of traditional refrigerator consumes a lot of conventional energy, indirectly on the more serious environmental pollution. From China’s current energy supply and environmental demands, the use of clean energy development is a trend that the refrigerator. In addition, there are many remote areas of China and the nomads into the supply network has not been, no conditional use refrigerator preserve food, the refrigerator for the development of solar energy offers a potential market. However, at this stage there are various factors which limit the solar refrigerator refrigeration technology widely used. On the one hand, due to inefficient use of solar energy, the price is high, and affected by aging, the relative concentration of buildings for residential, collector installation will be much more restricted; the other hand, there are many forms of solar refrigeration, but status of the current study, the various different forms of refrigeration systems are deficient. How to further improve the efficiency of the system and the joint operation of various refrigeration cycle are key areas for future research. Solar refrigerator system with the required new materials, new technology, environmental protection and energy saving appliances in the government policy support to rural areas, solar cooling in the refrigerator in the research and application will be a great development. The current consumption of large amounts of electricity to drive the traditional refrigerator technology has been maturing, just from the high efficiency, energy saving, energy saving refrigerator in terms of technological innovation has been difficult to have a major breakthrough, but there is a large solar refrigerator space for development, will be the future refrigerator industry in a direction. The development of solar refrigerator is a great innovation in the refrigerator industry, for the drive chain of the refrigerator to upgrade industrial technology has huge boost, and for environmental protection, energy saving and emission reduction made great contributions.
At present, solar refrigerators at home and abroad are also close to the most studied is the practical solar refrigeration refrigerator, while the study of solar adsorption refrigeration refrigerator, still in the basic theory of solar refrigeration prototype development and testing on. Solar refrigeration refrigerator refrigerators generally use the conventional solar power external devices, researchers focus on solar battery charge and discharge characteristics, the photovoltaic properties of the refrigerator compressor to consider less solar refrigeration refrigerator for matching the various components of the study is not perfect and the efficiency of solar heat sink is very low, and thus the efficiency of the system is not yet in comparison with the conventional refrigerator, the cost is much higher than conventional refrigerators. In the solar adsorption refrigeration refrigerator, the current research is more absorbent – refrigerant working fluid on performance, need to address how the heat transfer performance of adsorbent bed to further strengthen the adsorption bed, the collector heat during the day and night between the collector The relationship between effective solution, how effective cooling capacity of the night to day use of storage problems. Application of solar refrigerators currently in urgent need to further address the development of key technologies as follows: 1. Efficient solar collector solar collector technology is solar energy into heat energy in the solar system, plays an important role refrigerator, its efficiency and price will directly affect the entire solar refrigerator efficiency and economy. In order to improve the efficiency of solar collectors, the current research is mostly limited to the absorber and condenser unit structure improved, and endothermic nature of the collector of less investment, and reflects the endothermic nature of the optical properties of materials , that is, a band of light absorption capacity. Therefore, I believe that the surface of the absorber and absorbing coating materials research will be to improve the efficiency of solar refrigerators key collector, there are many worthwhile improvements in technology and development, as in a heat sink coated spectrum of solar radiation has a high absorption ratio of coating to keep the maximum collection of solar radiation; or radiation characteristics of the material in the rational use of heat-absorbing surface material to make it in the 0.3 ~ 3μm wavelength range of spectral absorption ratio close to at 1. 2. Efficient solar energy storage technology in order to overcome the timing of solar energy during the day and night caused by working conditions of the refrigerator is not the same defect in the system design should be to design a reasonable storage device to some of the energy generated during the day up Xucun for use at night or rainy days, truly all-weather cooling, in order to achieve the same effect with the conventional refrigerator. At present, solar energy storage have the following main, the capacitor energy storage, lead storage batteries, nickel metal hydride battery power storage and potassium-ion battery power storage. The application of the above storage battery technology has more mature, but storage capacity is too small, how to improve the capacity of the battery of the type of future research directions. Solar adsorption refrigeration and freezer is now being studied by energy storage technology, the main change is the use of the work process with the state media sensible heat, latent heat effect or chemical reaction process of reaction heat for energy storage. Because latent heat storage technology is the use of phase change materials absorb or release heat when needed features to store or release energy, the same principle with the adsorption refrigeration, so the latent heat energy storage technology research on solar adsorption refrigeration refrigerator storage is of practical significance . In addition, the solar adsorption refrigeration refrigerator storage technology, from the characteristics of the working fluid on its own research and development to be placed throughout the system, and the structure of adsorption refrigeration device for further improvement.
November 7, 2008 in Guangzhou at the “German Street” event, Siemens demonstrated its solar refrigerator, and is expected early next year in the domestic market, the price is expected in 8000 to 10,000 yuan. It is understood that this solar fridge solar energy into electricity using natural way of power supply, set in the refrigerator box outside the solar panels to collect solar energy in the outdoors into electrical energy and stored in batteries. Siemens introduces said the refrigerator using low-voltage power supply, DC compressor directly powered by solar panels, thereby reducing the DC / AC (DC / AC) inverter conversion link, improved energy efficiency. If the case of rainy days, the battery will continue to provide energy for the refrigerator. According to Siemens personnel, this solar refrigerators sold in Europe is very good, the hardware design and the main difference between an ordinary refrigerator power supply system using a voltage regulator to ensure that the solar power system stability. Power consumption of household electrical appliances is currently the country’s total electricity consumption has more than 15% of solar home appliances introducing green technology to the Chinese energy use and environmental protection is undoubtedly of great significance.
