The Distributed Energy Cold and Heat Source Station is a regional heating technology developed by the company to meet the demand for centralized heating in local towns and cities. It can construct a "point-grid integrated" regional centralized energy supply system based on the current status of regional buildings, replacing the urban heating infrastructure and achieving centralized energy supply for urban buildings (complexes). By combining with other energy sources, it reduces the consumption of traditional fossil fuels, not only proposing a new application model for shallow geothermal energy as an alternative heating source for buildings but also representing a completely new approach and attempt. It also opens up vast new spaces beyond the traditional market.
The Distributed Energy Cold and Heat Source Station is centered around the company's original "single-well circulation heat exchange ground energy collection technology" (hereinafter referred to as single-well technology). It primarily utilizes renewable shallow ground energy, complemented by clean energy sources such as joint natural gas, gas, or geothermal. The station integrates innovative renewable energy comprehensive utilization technology to provide centralized energy systems for heating, cooling, and domestic hot water for urban buildings. During the heating period, it supplies water at 50-55℃ to users, and during the cooling period, it provides water at 7-12℃. Its heating (cooling) method offers distinct advantages: clean, energy-saving, multifunctional, short construction period, low配套设施 requirements, small land area, reliable operation; it does not increase the burden on the urban power grid or other public facilities, and is planned and constructed in sync with infrastructure development. Modular configuration is adopted to adapt to the operation needs of buildings of different scales, ensuring stability in investment and operation. It can operate unattended with intelligent monitoring, ensuring safe and reliable system operation. Users enjoy individual metering, resulting in low operation costs.
Distributed ground-source cold and heat source stations are designed based on regional climatic conditions and thermal loads according to the "2/1" principle. The system server rooms and ground-source collection wells (groups) are designed as independent, point-like distributions in accordance with the regional building distribution. A network system interconnected among the point-like server rooms is arranged as an auxiliary energy exchange network. Deep ground-source or natural gas resources are configured in combination with the 1/3 power demand for the designed heating/cooling loads, considering the current regional energy status. These resources are utilized in the auxiliary energy exchange network to supply supplemental energy to the shallow ground-source energy supply system during adverse weather conditions using ground-source energy cascade utilization technology or natural gas heat, power, and cooling trigeneration technology. During the 2/3 interval of winter heating, a low-cost single-well circulation ground-source heat pump system is used for heating. In the 1/3 interval where winter weather is colder, through a smart control system, auxiliary energy supply is initiated in real-time based on regional climatic conditions and the energy supply capabilities of the cold and heat source stations, ensuring the entire system meets the regional energy demands.
