The air cooling and evaporative cooling are combined and optimized, and the air cooling part and the evaporative cooling part are rationally proportioned according to the ambient temperature and process cooling characteristics.

Application

Cooling of medium with large temperature difference between inlet and outlet; white fog is not allowed on-site; higher requirements for outlet temperature, continuity and safety.

Features

• Combined and optimized direct air cooling and evaporative condensers can complement each other. They can be operated together or independently.
• It can solve various problems in different seasons, and make full use of the advantages of no water consumption of air cooling system, water saving of evaporation system and low back pressure of condenser.
• Safety of the system is high.

Working flow

Dry and wet combined closed cooling system is combined from direct air cooling and evaporative condenser according to an optimizated design.

If the temperature is higher than the designed temperature to cut off water supply, evaporative cooling is the principal part for heat exchange and air cooling is the assistant part, and so most of thermal load is borne by evaporative cooling. If the temperature is lower than the designed temperature to cut off water supply, air cooling is the principal part for heat exchange and evaporative cooling is the assistant part, and so most of thermal load is borne by air cooling.
