In a regenerator 1, on the surface of a strip-shaped resin film 2, a resin layer 3 containing an ingredient having higher thermal conductivity than the resin film 2 is formed; or, over a predetermined width from an edge of the regenerator 1, a resin coating 4 is formed. Then, the resin film 2 is rolled into a cylindrical shape to produce the cylindrical regenerator 1. In a flow gas heat regeneration system having the regenerator 1 disposed in a doughnut-shaped space, when a hot working gas flows into the regenerator 1 through one end thereof, the heat of the working gas is stored in the resin film 2. Here, the resin layer 3 or resin coating 4 on the resin film 2 enhances heat conduction in the regenerator. Thus, more heat is stored in the resin film 2. When the cold working gas flows into the regenerator I through the other end thereof, the heat stored in the resin film 2 is rejected to the working gas. Here, the resin layer 3 or resin coating 4 on the resin film 2 enhances heat conduction in the regenerator 1 and increases the heat capacity thereof Thus, more heat is rejected to the working gas. In this way, it is possible to achieve high heat energy regeneration efficiency. <IMAGE> |
