As a professional home appliance brand with refrigeration for 30 years, Meiling has achieved a great reputation in energy conservation. Since 2000, Meiling has broken the 1 degree bottleneck of the industry with a 0.6-degree daily consumption refrigerator that shocked the industry. Since then, it has led the industry in energy saving.
Before the publication of the list of energy-saving subsidies, the “Changhong-Meiling Energy-saving Appliance Core Technology Press Conference†was held in Beijing. Meiling not only showed the world's energy-saving products with market competitive advantages and industry-leading core energy-saving technologies, but also its daily power consumption. The top energy-saving refrigerators of only 0.23 degrees caused mainstream media attention. Just announced the "2011 China Energy-Saving Products Enterprise Leaders List", Meiling won the "2011 China Energy-Efficient Product Leadership Award" and became one of the two domestic award-winning brands in the refrigerator category.
(1) Condenser pressure-preserving energy-saving refrigeration system with patent for invention
Blocking the heat exchange and pressure balance of the high and low pressure chambers after the compressor is stopped, reducing the heat load of the refrigerator, shortening the time required to reach stable working conditions at the time of starting, improving work efficiency, and reducing the loss of opening and stopping.
(2) Compressor refrigerator integrated design
Find the best point to match the design of the compressor to the operating conditions of the refrigerator. According to the actual operating conditions of the refrigerator, the optimal operating conditions of the compressor are deviated from the design to match the operating conditions of the refrigeration system of the refrigerator to improve the actual operating efficiency and reduce the power consumption of the refrigerator.
(3) Dynamic matching of refrigeration system
The matching method of the dynamic operation parameter matching of the refrigeration system combined with the static pull-down test. Based on software calculations, based on the best state of the pull-down test, and then simulate the actual
Use, adjust the system parameters according to the actual operating data to optimize. It not only reduces the power consumption in actual use, but also improves the adaptability and reliability of the system.
(4) Refrigerator heat load fitting calculation method is applied to product development
By calculating the rate of change of the new design product relative to the original product heat load, and according to the actual operating data of the refrigerator, through the data comparison of different refrigerators, fitting the same structure and
The design method of the leakage heat load calculation method of the refrigerator, and the application and verification in the development of the three-door refrigerator energy-saving refrigerator BCD-212D3CA
(5) Energy-saving technology related projects currently under development:
Insulation layer optimization: Reverse heat leak test is carried out on the refrigerator cabinet. The heat flow rate of each surface is measured by the heat flow sensor attached to the outer surface of the box. Quantitative analysis is carried out by thickening the thickness of the local foam layer and the heat load of the box. The rate of change provides directional guidance for the design of energy-efficient refrigerator cabinets.
