The cold and hot dual supply system is a kind of urban regional energy. By using the existing waste heat resources in the surrounding area, as well as local lakes and rivers, a large refrigeration station is established to form a regional energy center of a certain scale, to prepare and produce cold and hot medium water with low unit price. Through the establishment of a perfect transmission and distribution system, the centralized supply can replace the efficient energy supply scheme of single heating or cooling.

In areas with high demand for heating and cooling, such as industrial or densely populated areas, it is feasible to use regional energy regardless of the size of the city, which can effectively reduce the carbon footprint and energy use costs.
