Composite thermodynamic engine of power circulation system and refrigerating circulation system

Abstract

The inventive compound heat engine consists of a power circulation system and a refrigerating circulation system, in which is mounted a control system. It can provide the fields of power engineerings, refrigerating engineerings, communications and transportations, pumping irrigations and the like with mechanical work or electric energy. It not only can convert the high-grade energy, such as the fossil fuel, the nuclear fuel and soon into mechanical work or electric energy, but also can convert the low-grade heat energy stored in the seawater, the air and the earth crust into mechanical work or electric energy. Is also can convert the new energy like the solar energy and the renewable energy into mechanical work or electric energy.

Problems solved by technology

[0002] There are three defects in the conversion of existing fossil energy such as coal, oil and natural gas into mechanical energy and electrical energy: first, the reserves of fossil fuels are limited and will eventually be exhausted; second, the conversion of fossil energy into mechanical energy and electrical energy is accompanied by CO 2 , SO 2 , NO x Harmful gases such as harmful gases are produced, polluting the atmospheric environment, and causing global warming, melting glaciers, destroying the ecological environment, and frequent natural disasters. The low temperature is not low enough, so its thermal efficiency still has potential to be tapped. In the existing flat-plate or vacuum tube solar water heating system, the temperature of the hot water is generally in the range of 45°-70°. The water source at high temperature is a low-temperature cold source, and its temperature drop is small, so the efficiency of the heat engine is low, the unit power conversion cost is high, and the economy is poor. Small, its thermal efficiency is low, and its economy is poor. For example, the surface water temperature of the deep sea can reach 34°C, while the temperature of the bottom of the deep sea is only 4°C, and the temperature drop is only 30°C. Low-grade thermal energy in energy sources has not been developed so far and converted into mechanical energy and electrical energy
