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%.

How to properly clean the air conditioner yourself

After a winter of inactivity, the air conditioner that has been "dusted" for a long time is reactivated. It is believed that most of the friends are directly plugged in and turned on. In fact, this is not correct. <img src="{{media url=&quot;How_to_properly_clean_the_air_conditioner_yourself.jpg&quot;}}" alt="" /> It is necessary to know that the air conditioner has accumulated dust and breeds bacteria after being left for a long time. Blowing out with the wind seriously threatens your health. This is actually due to the working principle of the air conditioner: when cooling, the room temperature air is continuously sucked in, filtered by the filter, and then cooled by the fins of the heat exchanger, and finally the cold air is blown out, and then returned to the room for reciprocating circulation.

Tips for compressors using refrigeration oil

The amount of frozen oil used. The amount of refrigerating oil should be controlled after the installation of the overall refrigeration system. After the trial operation, the oil return position of the refrigerating oil seen from the sight glass of the compressor should be at the center line of the sight glass.

Composition principle of refrigeration system of refrigerator

Composition principle of refrigeration system of refrigerator Refrigerators have a larger cooling capacity than household refrigerators, and there are more refrigerants filled in the system. Therefore, a liquid storage tank is installed on the pipeline between the condenser and the filter, and a shut-off valve is installed on the tank to shut down the system for a long time. When closing the shut-off valve, the refrigerant liquid is stored in the tank.<img src="{{media url=&quot;Composition_principle_of_refrigeration_system_of_refrigerator.jpg&quot;}}" alt="" />
