Theme A: Connecting the Pearl River Delta RegionIn summer, river water source air-conditioning discharge the waste heat into riverinstead of into the ambient air so as to mitigate the heat island effect. And in winter,this change can reduce the use of the chemical fuel and the discharge of SO 2 andNO X by utilize the clean electricity.The heat discharged into the river would result in the increase of river watertemperature. The excessive high temperature may affect the ecology in the river. Inthis project, because of the rich water and strong mix in Jialing River, the heatdischarged into the river will diffuse quickly. The water temperature increase aslittle as 0.0019 ℃ under theoretical calculation which can be ignored. Thereforethe river water source air-conditioning system has no destruction to theenvironment.5. CONCLUSIONAfter comparative analysis, it can be seen that the river water air-conditioningsystem can save 33% energy per year, besides it has little adverse effects on theenvironment.In the south regions of China there are many rivers, which contain a considerableamount of renewable. Clean energy can be applied to cooling and heating projects.The adoption of this kind of energy reasonably will promote greatly thedevelopment of energy conservation enterprise.6.
