Factors affecting heat transfer on the refrigerant side

1.Flow direction and velocity of steam In the condenser, when the refrigerant vapor contacts the low-temperature wall surface, it exotherms and condenses into a liquid film, and flows downward under the action of gravity.

Two working methods for air filter manufacturers to reduce air pollution

Two working methods for air filter manufacturers to reduce air pollution 　　1. Air filter manufacturer: air filter 　　Air Filter Manufacturers Air filters are equipment developed based on air pollution. It can effectively reduce air pollution, but it must be known that its purification range is relatively small. Therefore, users should pay attention to actual application requirements when using them and purchase appropriate equipment.
