Environmental
- Electricity consumption of District Cooling System
- Compared to water-cooled system, it saves 20% on electricity;
- Compared to air-cooled system, it saves 35% on electricity.
- The maximum annual saving in electricity consumption upon full utilization of all the systems is estimated to be 230 million kWh.
Other Aspects
In addition to high energy efficiency, district cooling system will also bring the following benefits to the Consumers:
- Save upfront capital cost of consumers, as chiller plants are not required at consumer buildings. The reduction is about 5% to 10% of the total building cost.;
- Consumers do not require to install independent chiller plant as well as the associated power supply equipment for their building and therefore enhanced the building design flexibility;
- Reduce urban heat island effect, improve outdoor air quality, to achieve the target of sustainable development and low-carbon economy;
- Consumer buildings with the adoption of district cooling services do not require to install chillers and heat rejection equipment, thus noise and vibration generated by plant equipment can be eliminated. Meanwhile, more space is available for greenery and installation of renewable energy systems;
- Comparing with independent air-conditioning system, district cooling system is more flexible to cater different cooling demand among various buildings. In case of building cooling demand is increased, the Consumer can request for extra chilled water supply from the district cooling system, no large-scale alternation work is required.
