District Cooling

What is district cooling?: District cooling is an advanced cooling system that reduces power peak load in summer by using alternative energy such as residual heat from a co-generation plant by supplying economically produced hot water or cold water to a certain area.

District cooling contributes to energy saving and environment improvement in our country.

It improves the electricity shortage in summer due to cooling.
- Compared to other cooling systems with high electricity consumption, the electricity consumption is lower, which reduces the power load during summer.
It protects the atmospheric ozone layer.
- It uses water as a refrigerant instead of greenhouse gas that causes global warming, such as Freon Gas (CFC); thus protecting the ozone layer and improving the atmospheric environment.
It maximizes energy utilization.
- The cooling supply using district heating heat improves the utilization efficiency of the co-generation plant in summer.

Cold Water Direct Supply Method
- Cold water is made from economical energy, such as residual heat produced by a co-generation plant and ice storage using late-night electricity, and is supplied directly to buildings through pipes in a large-scale built-up area.
Hot Water Supply Method
- The residual heat generated by the generation of electricity from the co-generation plant is sent to the building's user facilities through pipes to make cold water using the absorption chiller and supply it to each room.
