For cold storage to be more energy efficient, this should be done!

For cold storage to be more energy efficient, this should be done! 1. The index for reducing the unit heat flow of the cold storage enclosure structure. In the design of the cold storage, the unit heat flow q of the outer wall of the low-temperature cold storage is generally about 11.63W. If the q can be reduced to 6.9W, for a 5000T~10000T class In low-temperature cold storage, it is estimated that the power cost can be reduced by about 10%.

Working principle of sliding vane compressor_Features of sliding vane compressor

Working principle of sliding vane compressor <img src="{{media url=&quot;magefan_blog/Working_principle_of_scroll_compressor_Characteristics_of_scroll_compressor.jpg&quot;}}" alt="" /> 　　 Air is sucked in through a filter and a regulating proportional valve. The regulating valve is mainly used to regulate the pressure chamber formed by the rotor and slide of the air cylinder. The rotor rotates eccentrically with respect to the cylinder, the valve plate is installed in the rotor groove, and the slider is pushed to the cylinder wall by centrifugal force.
