AI Technical Summary
In existing carbon dioxide gas-liquid two-phase energy storage systems, the high-pressure gas pressure energy between the compressor and condenser is wasted when the system is shut down, resulting in reduced energy storage efficiency.
Design a system to reduce gas recovery in the main exhaust pipe. By setting a check valve and a recovery flow path, when the compressor stops, the high-pressure gas is depressurized and cooled by the return valve and return heat exchanger and then returned to the gas storage tank, avoiding the gas from directly entering the condenser and realizing the reuse of the gas.
It effectively reduces the waste of high-pressure gas pressure energy between the compressor and condenser, improves the energy storage efficiency of the energy storage system, and prevents compressor surge.
