District energy sharing system

Abstract

A district energy sharing system (DESS) comprises a thermal energy circuit which circulates and stores thermal energy in water, at least one client building thermally coupled to the circuit and which removes some thermal energy from the circuit ("thermal sink") and / or deposits some thermal energy into the circuit ("thermal source"), and at least one thermal server plant that can be thermally coupled to external thermal sources and / or sinks (e.g. a geothermal ground source) and whose function is to maintain thermal balance within the DESS.

Description

technical field [0001] The invention relates to an area energy sharing system for sharing thermal energy between servers and clients in an area. Background technique [0002] Traditional building heating and cooling systems use primarily advanced energy sources, such as electricity or fossil fuels, to provide space heating and / or cooling and to heat or cool water used in the building. The process of heating or cooling building spaces and water converts this high-grade energy into low-grade waste heat with high entropy, which then leaves the building and returns to the environment. Heated water eg from a shower or sink drains into the sewer and the thermal energy in the heated air will radiate and conduct through the outer walls into the atmosphere. [0003] Building heating and cooling systems consume large amounts of non-renewable resources and contribute significantly to global warming. Many industrial processes also emit large amounts of low-grade heat that further warm...

AI Technical Summary

Problems solved by technology

Efficient operation is also hindered when some building heat pumps are heating and some are cooling because there will be substantial temperature variation along the loop and additional measures will need to be employed to maintain the temperature of the loop within its designed operating range
