Industrial pressure water is usually used for cooling. The cooling water pressure should be maintained at 0.15-0.20MPa, the water temperature should be maintained at an inlet 

temperature of 20-35℃, and the outlet temperature should be lower than 55℃. If the cooling water temperature is too low, condensation will occur, and if the water temperature exceeds 55℃, the cooling capacity will be lost. In order to save water, a circulating cooling system can be used.
