Abstract:
A low-temperature waste-heat-gas driven refrigeration system having a high-temperature-side heat exchanging portion and a low-temperature-side heat exchanging portion, comprising:a high-temperature-side heat exchanger as the high-temperature-side heat exchanging portion, provided with high-temperature-side hydrogen storage alloy containers arranged substantially in parallel with each other so as to form gaps therebetween, wherein each of said high-temperature-side hydrogen storage alloy containers is provided with a pipe body and contains a hydrogen storage alloy disposed inside the pipe body, which is aerated for absorbing and releasing hydrogen; an exhaust gas importing duct connected to said high temperature-side heat exchanger for delivering a low temperature waste-heat gas to said high temperature-side heat exchanger; a cooling water pipe connected to said high temperature-side heat exchanger for delivering a cooling water to said high temperature-side heat exchanger, wherein one of the low temperature waste-heat gas and the cooling water is alternately delivered into said high temperature-side heat exchanger for performing heat exchange; a low-temperature-side heat exchanger provided with low-temperature-side hydrogen storage alloy containers as the low-temperature-side heat exchanging portion, wherein each of said low-temperature-side hydrogen storage alloy containers contains a hydrogen storage alloy for absorbing and releasing hydrogen; and a plurality of heat medium pipes connected to said low-temperature-side heat exchanger for delivering a cold-heat heat medium into said low-temperature-side heat exchanger for performing heat exchange therebetween so as to obtain a cold heat at the low-temperature-side heat exchanger, wherein said low-temperature-side hydrogen storage alloy containers are connected to said high-temperature-side hydrogen storage alloy containers so that hydrogen moves therebetween, and wherein said cold heat is supplied into a refrigeration output portion through said cold-heat heat medium which receives said cold heat from said low-temperature-side heat exchanger.
