Reasonably adjust the cold storage evaporator and defrost in time

Reasonably adjust the cold storage evaporator and defrost in time Generally speaking, every increase in the cold storage evaporation temperature can save energy Therefore, under the premise of satisfying the low refrigeration process of the product, the evaporation temperature can be increased as much as possible by adjusting the amount of liquid supplied. The thermal resistance of the frost layer is generally much larger than the thermal resistance of the steel pipe.

Characteristics and Control of Exhaust Noise of Air Distribution Valve in Pneumatic System

In a pneumatic system, the air intake and exhaust of the cylinder are controlled by an air distribution valve, and the noise generated by the air discharged into the atmosphere through the exhaust port of the distribution valve is often greater than the noise generated by any part of the pneumatic system. And cause serious damage and pollution to the operators and the surrounding environment [2].
