What is chilling waters?

As an AI language model, I am not sure what you exactly mean by "chilling waters". But if you are referring to "chilled water systems", then here is some information on chilled water systems.

A chilled water system is a type of HVAC (heating, ventilation, and air conditioning) system that circulates chilled water through pipes to cool down the air in a building or facility. The chilled water is produced by a chiller, which is a machine that removes heat from the water and sends it back into the system to be cooled again.

Chilled water systems are commonly used in larger buildings such as office buildings, hospitals, and universities. They can provide efficient and cost-effective cooling, as the same system can be used to cool multiple areas within the building. The system can also be used for heating, by using a heat exchanger to transfer heat from the chilled water to warm up the air.

Chilled water systems can be designed in a variety of configurations, including air-cooled and water-cooled systems. Water-cooled systems typically use cooling towers to remove heat from the water, while air-cooled systems use air-cooled condensers.

Overall, chilled water systems are an effective and energy-efficient way to provide cooling and heating for larger buildings.
