Ground source heat pump screw water chiller

Broadly speaking, regional energy is defined as: "In a particular area, all forms and grades of energy required for people's production and life are reasonably, integratedly and efficiently produced, transmitted, distributed, utilized and consumed. Scattered". In a narrow sense, regional energy is defined as: "The integrated integration of district heating, district cooling, district power supply, and energy systems that address regional energy needs. The regions referred to here can be administratively divided cities or various parks, Or a building complex." Regional energy provides energy services to buildings and other service objects through the energy network system to achieve the reception, production, transmission and distribution of primary and secondary energy; the main forms of energy usually include electricity, gas, and hot water. /Steam (regional heating), cold water (regional cooling); the system types involved are: boiler room heating system, chiller cooling system, thermal power plant system, combined heat and power system, heat pump energy supply system, solar energy utilization System, wind power generation system and biomass energy system, etc. Different forms of energy services in the region usually run in parallel, so an important role or value of regional energy is: "Based on the specific end energy needs (form, grade, and dissipation) in the region, through the optimization of the energy system running in parallel Integration to achieve grade correspondence and temperature

Counterpart, cascade utilization, multi-energy complementary energy production, supply and utilization".

River water source heat pump systems, sewage source heat pump systems, and seawater source heat pump systems can connect these energy sources to a distributed energy system through a pipe network, but the energy consumption for transmission is often 15-30% higher than the energy consumption for cold and hot water in centralized energy stations.

If the scale of the pipe network is too large, it is easy to cause thermal imbalance caused by hydraulic imbalance. The larger the scale, the more serious this phenomenon.

Must consider the use of renewable energy, waste heat and waste heat utilization, energy ladder utilization, heat pump system based on various low-grade heat sources, geothermal cascade utilization, etc.

Energy storage is almost necessary, using the peak-valley price difference of energy to improve the economic performance of the system, realize the decoupling of real-time load and equipment operation, and improve the system operating efficiency.
