Solar Refrigerator To Achieve The Automatic Control Of The Refrigerator Temperature



Solar refrigerators mainly include solar photovoltaic refrigerators and solar semiconductors. Solar photovoltaic refrigerator is based on the traditional traditional compression refrigerator developed by the solar cells, controllers, batteries and refrigerators and other components. Solar Freezer and Refrigerator As the internal structure of solar photovoltaic refrigerator with the traditional refrigerator the same, but the power supply device to solar cells, so it is relatively simple to achieve.

Solar refrigerators use natural solar energy to convert electricity into electricity, set up in the refrigerator box solar panels, solar energy collected in the outdoor into electrical energy, Solar Freezer and Refrigerator and stored in the battery. Siemens said that the refrigerator using low-voltage power supply, DC compressor from the solar panel directly to power, thereby reducing the DC / AC (DC / AC) inverter conversion link, Solar Freezer and Refrigerator improve the energy efficiency. If you encounter rainy days, the battery will continue to provide energy for the refrigerator.

Solar refrigerator is characterized by activated carbon as a solid adsorbent, water for the refrigerator working fluid, the use of activated carbon in the sun under the evaporation of water vapor and no water to absorb the principle of water to achieve the refrigeration cycle, Solar Freezer and Refrigerator because the water from the liquid into the gas when the absorption A lot of heat, making the surrounding media cooling, resulting in cold steam, at any time in the form of ice storage. The refrigeration unit does not require electricity for energy, is used in rural areas and lacks electricity and where solar rays are available. In the case of

Solar refrigerators mainly include solar photovoltaic refrigerators and solar semiconductors. Solar photovoltaic refrigerator is based on the traditional traditional compression refrigerator developed by the solar cells, controllers, batteries and refrigerators and other components. As the internal structure of solar photovoltaic refrigerator with the traditional refrigerator the same, but the power supply device to solar cells, Solar Freezer and Refrigerator so it is relatively simple to achieve.

The 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 ℃, the refrigerating compartment can reach 0 ~ 10 ℃, Solar Freezer and Refrigerator 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 method used in the solar photovoltaic refrigerator frequency conversion circuit, and to achieve the automatic control of the refrigerator temperature.
