Application analysis and research of water/hot and cold combined transport system
In order to deal with the problem of water pollution and lack of water resources,in response to the national energy policy of low carbon,environmental protection,energy saving,emission reduction and comprehensive efficiency,improve the recycling rate of renewable water and the utilization rate of renewable energy in the field of heating(cooling),the use of recycled water quality is good,the water temperature and water quantity are relatively stable,and the recycled water plant is used as a comprehensive energy station.It is transported to the end of the urban hot(cold)load through the new pipe such as prefabricated insulation ductile iron pipe.After heating(cooling)by distributed heat pump unit,the quality and amount of reclaimed water are basically unchanged,and can be further used as urban landscape water,industrial water,etc.The water hot and cold combined transport system uses the long-distance transport network to transport,which can realize the same transport of recycled water and hot(cold)single pipe,reduce investment and save energy.Distributed heat pump unit according to the end load demand,one machine multi-purpose,high efficiency and energy saving,economic operation;The reclaimed water after heat transfer can be reused to increase the comprehensive utilization rate of reclaimed water resources.The water-hot and cold co-transport system realizes the efficient and comprehensive utilization of recycled water,and simultaneously provides heating,cooling and recycled water,which improves the comprehensive efficiency of energy,breaks the conventional industry barriers,and has certain promotion significance.
