Abstract

Official abstract text for this publication.

A heat absorption and radiation system uses a heat medium containing a rubidium-manganese-iron cyano complex, and is configured to release heat from the heat medium by applying a pressure to the heat medium and causing phase transition of the rubidium-manganese-iron cyano complex from a high-temperature phase to a low-temperature phase, absorb heat into the heat medium by releasing the pressure applied to the heat medium and causing phase transition of the rubidium-manganese-iron cyano complex from the low-temperature phase to the high-temperature phase, and repeat application of the pressure to and release of the pressure from the heat medium. Thus, it is possible to efficiently absorb and release heat through effective utilization of the characteristics of the rubidium-manganese-iron cyano complex.

First claim

Opening claim text (preview).

The invention claimed is: 1 . A heat absorption and radiation system that is configured to use a liquid heat medium obtained by mixing a rubidium-manganese-iron cyano complex into a liquid, the heat absorption and radiation system comprising: a circulation passage; a pump configured to circulate the liquid heat medium in the circulation passage; a valve configured to open and close the circulation passage on an upstream side of the pump; a pressurizing device configured to pressurize, on a downstream side of the pump, the liquid heat medium present on an upstream side of the valve in the circulation passage, and a processor that is configured to control the circulating passage, the pump, the valve and the pressurizing device in order to: release heat from the liquid heat medium by applying a pressure to the liquid heat medium and causing phase transition of the rubidium-manganese-iron cyano complex from a high-temperature phase to a low-temperature phase, absorb heat into the liquid heat medium by releasing the pressure applied to the liquid heat medium and causing phase transition of the rubidium-manganese-iron cyano complex from the low-temperature phase to the high-temperature phase, and repeat application of the pressure to and release of the pressure from the liquid heat medium. 2 . The heat absorption and radiation system according to claim 1 , wherein iron of the rubidium-manganese-iron cyano complex is doped with cobalt. 3 . The heat absorption and radiation system according to claim 1 , wherein manganese of the rubidium-manganese-iron cyano complex is doped with divalent metal ions. 4 . The heat absorption and radiation system according to claim 1 , wherein the heat absorption and radiation system further includes a second valve configured to open and close the circulation passage on the downstream side of the pump and on an upstream side of the pressurizing device.
