Improved stirling engine design and assembly

摘要

A method for pressurisation of a working gas in a Stirling engine assembly for use in a thermal energy plant, the Stirling engine assembly comprising: a Stirling engine comprising an expansion cylinder and a compression cylinder, wherein the expansion and compression cylinders are configured in a V-arrangement, the Stirling engine assembly further comprising a regenerator, a cooler and a heater and an accumulator, said accumulator being in fluidic connection with the expansion and/or compression cylinders of the Stirling engine, the Stirling engine assembly further comprising a low pressure receptacle comprising the working gas, the method comprising: providing working gas to the accumulator from the low pressure receptacle, providing a pressurisation fluid to the accumulator to reduce the volume for the working gas in the accumulator, thereby increasing the pressure of the working gas in the accumulator, and displacing the pressurised working gas from the accumulator to the expansion and/or compression cylinder.
