What methods are there to cool 95-degree, 4 tons per hour of hot water to room temperature?
Using different media for heat exchange at various temperature ranges may result in relatively high costs for equipment and initial investments, in my opinion
4 tons per hour. It depends on the properties and uses of the material; if it’s necessary to pre-treat the material through heat exchange, the temperature can be reduced by about 30 degrees first. Then, heat exchange with a cold water tower equipped with a fan can bring the temperature down to around 35 degrees, after which the material can be discharged directly! ! Hehe, another option is to create a large pool from which water can overflow, thereby reducing the temperature! Multiple approaches can be combined! It would be best to be able to recover heat!
Establish heat recovery, which can be used for air conditioning cooling.
Looking at the parameters listed by the poster, it seems to be steam condensate; could a condensate recovery system be considered?
It is a pilot-scale device designed to reuse water while reducing investment costs
Pilot-scale equipment to lower water temperature and reuse water, with the hope of reducing equipment investment
A small hot-water type cooling tower will do; the investment is very low. The diameter can be one meter.
Such a large amount of heat can definitely be utilized; there are always areas in the factory that need to be preheated, so it can be used directly for preheating materials, which is energy-saving and environmentally friendly
