AI Technical Summary

Problems solved by technology

This invention utilizes the waste heat generated by the generator set to generate electricity. Since the heat generated by the waste heat is less, the power of the organic working medium expander is lower, so that the power generation efficiency of the generator is lower, and the condenser adopts liquid cooling. method, the scope of application is limited, and it cannot be widely used
