Low-temperature waste-heat-gas driven refrigeration system

摘要

High-temperature-side hydrogen storage alloy containers each containing a hydrogen storage alloy are disposed as a heat exchanging portion in high-temperature-side heat exchangers. Low-temperature waste-heat gas generated in a micro gas turbine is imported into the heat exchangers so that direct heat exchange is performed between the waste-heat gas and each of the alloy containers. On the other hand, low-temperature-side hydrogen storage alloy containers each containing a hydrogen storage alloy are disposed as a heat exchanging portion in low-temperature-side heat exchangers. The high-temperature-side alloy containers and the low-temperature-side alloy containers are connected to each other by hydrogen-travelling pipes. Cold heat generated in the low-temperature-side heat exchangers is supplied to a refrigeration output portion.
