See the real chapter for details, small technology to solve big problems-talk about tunneling effect and its improvement

In the introduction of adsorption dryers, the term "tunneling effect" is often mentioned. So what exactly is "tunneling effect"? We call the phenomenon of uneven air distribution in the drying tower, rapid flow in the middle and slow flow at the edges as Rﰨ2䀀湠癒Vǜ

Does car air conditioner cost oil for cooling or heating? Do you really know?

The compressor of the car air conditioner is driven by the engine. Turning on the air conditioner is equivalent to increasing the engine load. Of course, it will consume more fuel. The fuel consumption of the car when the air conditioner is turned on is higher than when it is not turned on, and the fuel consumption is not increased when heating.

The history of industry

China is one of the first countries in the world to invent rolling bearings. According to archaeological relics and data, China’s oldest bearing with the prototype of a modern rolling bearing structure appeared in Xuejiaya Village, Yongji County, Shanxi Province from 221 to 207 BC (Qin Dynasty).

Refrigeration, Air Conditioning Compressors: Reciprocating, Rotary, Screw, Centrifugal, Scroll

What is Refrigeration Compressor The compressors are one of the most important parts of the refrigeration cycle. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. It then moves to the expansion valve, and the evaporator and it is finally sucked by the compressor again. For the proper functioning of the refrigeration cycle, the refrigerant must be compressed to the pressure corresponding to the saturation temperature higher than the temperature of the naturally available air or water. It is the crucial function that is performed by the compressor. Compression of the refrigerant to the suitable pressure ensures its proper condensation and circulation throughout the cycle. The capacity of the refrigeration or air conditioning depends entirely on the capacity of the compressor.<img src="{{media url=&quot;422C8FF7C729C6E9A7416FCA7C2EB508849153E1_large.jpg&quot;}}" alt="" />
