Self-cooled thermal power acting method

Abstract

The invention relates to a self-cooled thermal power acting method and belongs to the field of thermal energy power. A working medium of a thermal power system absorbs heat from a heat source to act. The self-cooled thermal power acting method includes the temperature rising process in which after the pressure of the working medium which is in a low temperature state is boosted and the working medium is heated, the working medium becomes a power air source, the expansion acting process carried out after the power air source enters an expansion acting system and the heat releasing process in which heat of the low-temperature gas working medium which carried out expansion acting is further released. The thermal power system achieves the thermal power circulating process from the temperature rising process, the expansion acting process, the heat releasing process and the temperature rising process. A thermal pump process is used for cooling or liquefying the gas working medium which carried out expansion acting. When heat is released in the thermal pump process, the temperature or the pressure parameter of the working medium is lower than the maximum parameter of the power air source. In the expansion acting process, partial or overall heat which is released in the thermal pump process is absorbed and common acting is carried out. A heat returning process is adopted, so that the heat released by the system is absorbed in the system heat absorbing process. An air energy engine with practicability is obtained, and high-efficiency thermal power circulation of all sorts is achieved. Meanwhile, the invention provides a novel jetting air ejector and a novel thermal pump optimizing system and cost is reduced.

Description

technical field [0001] The invention belongs to the field of thermal power. Background technique [0002] The second law of thermodynamics is that the basic conclusions of thermodynamics have never been shaken, but following its law, the thermodynamic work system must discharge heat to a low-temperature heat source, which always results in huge waste of energy. For example, the thermal efficiency of a single-cycle work process is only close to 50%, such as the thermal efficiency of a gas turbine. Less than 40%, although there are no questionable reports in the mainstream thermodynamics field, this does not stop people from exploring and thinking about it, especially in today's energy crisis and serious environmental damage, any possible breakthrough is very important. There are some solutions to realize the work done by a single heat source. Unfortunately, there are no practical cases. In summary, there are several solutions as follows: (1) Use heat pump to generate heat to ...

3. The traditional jet extractor has a large flow loss and low efficiency due to the throat zoom structure, and its structure and performance have a lot of room for improvement. In addition, it is simple and has no rotating parts, and the working medium is heated by the liquid pump force to generate power. The consumption of compression work is the smallest, that is, there is a lot of room for improvement in the performance of jet pumping refrigeration technology
