Unchanging specificity, changing technology, "Suqian Insurance Town"-distributed multiple cold and heat source solutions

The insurance town is the first town in the country with the insurance industry characteristics. It adopts the "converted cities" (ie, the National Insurance Regulatory Commission, the Jiangsu Provincial Government, and the Suqian Municipal Government) joint construction model. The whole industry chains such as commerce, settlement, data, and disaster recovery provide tailor-made development space. The total construction area included in the energy supply is about 2.6 million square meters. Considering the park construction plan, the total energy supply area in the starting area is about 230,000 square meters.
   Our company uses the cold and heat source scheme to adopt distributed multi-energy complementary and cascade utilization supply methods, including distributed air source heat pumps, traditional water source heat pumps, magnetic suspension chillers, ice storage, heat storage, photovoltaic power generation, solar hot water, etc. Through the mutual complementation and cascade utilization of distributed energy stations, give full play to their respective energy efficiency advantages, that is, to meet the cold and hot demands of the construction progress of the park, but also to fully improve the operating efficiency of cold and heat sources and reduce repeated investment in cold and heat source equipment
In summer, the cold source of air-conditioning adopts the combined cooling mode of chiller + air source + ice storage system. Give full play to the characteristics of high cooling efficiency of water-cooled heat pump units, and give play to the high energy efficiency characteristics of magnetic suspension chillers during most low load periods. Give full play to the characteristics of the dual-mode magnetic suspension chiller, operate with large temperature difference, and save power consumption. Make full use of cold electricity storage at night troughs, release cold during the day, reduce energy costs, reduce installed capacity and grid load during peak periods. In winter, the coupled heat pump system is used as the heat source. Make full use of refrigeration equipment for heating (air source heat pump and water-cooled heat pump) adopt the step heating principle, air source heat pump provides low-temperature hot water, series water-cooled heat pump provides high-temperature hot water, in order to give full play to air source heat pump and water source heat pump in the corresponding working conditions
High energy efficiency characteristics.
   This energy station has a total investment of 45.805 million yuan, technically adopts a mature and reliable, high-efficiency cold and heat source form, combined with Jiangsu Peak Valley electricity price policy, the overall operating cost is low, the overall static recovery period is about 4.27 years, and the overall internal income The rate is about 25.4%, and investment and operation have good feasibility.
