Therefore, it is generally necessary to use water cooling or air cooling to dissipate heat from the condenser, and for this purpose, the condenser is divided into a water cooling condenser and an air cooling condenser.
however, the air-cooled condensers currently manufactured by most manufacturers are generally designed in a constant flow manner. The constant flow type air-cooled condenser can not adjust the air volume according to the change of the environmental temperature, and causes the abnormal operation of a host system caused by overhigh or overlow system pressure, so the constant flow type air-cooled condenser is limited by the influence of the environmental temperature, and has a narrow application range.
