DEVICE FOR UTILIZATION OF VOLUMETRIC EXPANSION OF GAS

摘要

[Problem] To reduce the energy used by a refrigeration cycle device. Adiabatic compressors are used in refrigeration cycle devices, and most are driven by electric power. Technology is required for refrigeration cycle devices to conserve electricity and generate electricity using renewable energy when the power from an electric power supply is insufficient. [Solution] A gas that is not at critical temperature is liquefied by volumetric expansion. The energy extracted at the time of liquefaction is used to generate electricity.
