物質熱エネルギーから有効仕事を取り出す新規熱サイクル －新規熱サイクルを用いた複合発電システムについて－

抄録

The ways of using solar energy for human being are to use solar cells for direct solar ray, or to warm up object by using radiant heat of the sun. However, most of the solar energy which is showered upon the earth is used for the heat-reserve in seawater and the earth. There seems not to have existed in the past that the ways of thinking to utilize heat energy near the normal temperature as the effective work, exergy, which was directly stored up in the earth.
This paper presents a new energy source, which is got from room temperature heat source. There exist a new heat cycle that creates exergy from room temperature materials. This is composed of a unique heat cycle of CO₂ gas as a heat medium. The mechanism is shown through exergy analysis as to the heat cycle which creates valid work. Proper systems are discussed on generation of electricity, and warm or cold heat, using this cycle.
