The inventor proposes the new elaboration mode of out-of-phase diagram as described below and the second law of thermodynamics:
Pressure and temperature is the most basic, the most important status parameter of working medium.Yet in thermodynamic study up to now, not having to be that the out-of-phase diagram of coordinate is used for the research to thermodynamic process and thermodynamic cycle with pressure P and temperature T.In more than 200 year since thermomechanics is born, the inventor proposes the thought with out-of-phase diagram research thermodynamic process and thermodynamic cycle for the first time.In utilizing out-of-phase diagram research thermodynamic process and thermodynamic cycle, the inventor finds that out-of-phase diagram all has remarkable advantages than P-V figure commonly used and T-S figure, it more constitutionally the variation of working medium state in thermodynamic process and the thermodynamic cycle is described, make the inventor to thermodynamic process and thermodynamic cycle more deep understanding be arranged.Utilize out-of-phase diagram, the inventor has summed up the new elaboration mode of ten second laws of thermodynamics, though it is of equal value that these new elaboration modes and Kelvin in the past and Clausius's thermomechanics is set forth mode, but clearer and more definite announcement to the difference of heating process and the compression process of working medium, also indicated direction for the exploitation of high efficiency thermal machine.This new method and new law will promote thermodynamic (al) development and hot machine progress of industry greatly.Specific as follows:
P-V figure and T-S figure are widely used in thermodynamic study already, yet in view of P, T are the most important status parameters of working medium, so the inventor is that coordinate has been drawn out-of-phase diagram with pressure P and temperature T, and Carnot Cycle and Otto Cycle are identified in the out-of-phase diagram shown in Figure 10.Clearly, out-of-phase diagram makes the variation of working medium state in thermodynamic process and the thermodynamic cycle more apparent, and the essence of thermodynamic process and thermodynamic cycle is more readily understood.For example: the out-of-phase diagram of Carnot Cycle shown in Figure 10, can make the inventor easily draw such conclusion: the mission of the reversible adiabatic compression process of Carnot Cycle is in the mode of reversible adiabatic compression the temperature of working medium to be increased to the temperature of its high temperature heat source, under the prerequisite that is consistent with the temperature that realizes with high temperature heat source from high temperature heat source constant temperature heat absorption inflation process.In addition, the inventor can also find out significantly: when the temperature of the high temperature heat source of Carnot Cycle raises, the inventor must be with more plus depth ground compression of working medium in the reversible adiabatic compression process of Carnot Cycle, make it reach higher temperature, to reach the temperature of the high temperature heat source after the intensification, with realize with heat up after the prerequisite that is consistent of the temperature of high temperature heat source under high temperature heat source constant temperature heat absorption inflation process after heating up, thereby the raising of implementation efficiency.
According to adiabatic process equation
(wherein,
Be constant,
Be the adiabatic index of working medium), the inventor is with difference
The curve of adiabatic process equation of value is plotted among Figure 11.According to mathematical analysis, and as shown in figure 11, any two adiabatic process curves are all non-intersect.This means: the process on same adiabatic process curve is adiabatic process, and with the process of any adiabatic process curve intersection be diabatic process, in other words, the process of two different adiabatic process curves of any connection is diabatic process (so-called diabatic process refers to have the process that heat transmits, the i.e. process of heat release and the process of heat absorption).In Figure 12, the inventor has marked two state points, namely puts A and puts B.If a thermal procession or a series of interconnective thermal procession are from an A point of arrival B, then the inventor is referred to as the process of tie point A and some B, otherwise the inventor is referred to as the process of tie point B and some A.According to shown in Figure 12, the inventor can draw such conclusion: on adiabatic process curve at an A place, then tie point A is adiabatic process with the process of some B as a B; As the right side of a B at adiabatic process curve at an A place, then tie point A is endothermic process with the process of some B; As the left side of a B at adiabatic process curve at an A place, then tie point A is exothermic process with the process of some B.Because the process of tie point A and some B may be exothermic process, adiabatic process or endothermic process, so the inventor is reference with a B, will put A be defined as respectively have superfluous temperature, ideal temperature and not enough temperature.In like manner, the process of tie point B and some A may be exothermic process, adiabatic process or endothermic process, so the inventor is reference with an A, will put B be defined as respectively have superfluous temperature, ideal temperature and not enough temperature.
By these analyses and definition, the inventor draws following ten about the new elaboration mode of the second law of thermodynamics:
1. do not have the participation of endothermic process, exothermic process can not be returned to its initial point.
2. do not have the participation of exothermic process, endothermic process can not be returned to its initial point.
3. do not have the participation of diabatic process, diabatic process can not be returned to its initial point.
4. only use adiabatic process, diabatic process can not be returned to its initial point.
5. when making the pressure of endothermic process return to the pressure of its initial point with the thermal procession beyond the exothermic process, its temperature necessarily is higher than the temperature of its initial point.
6. when making the pressure of exothermic process return to the pressure of its initial point with the thermal procession beyond the endothermic process, its temperature necessarily is lower than the temperature of its initial point.
7. endothermic process can produce superfluous temperature.
8. exothermic process can produce not enough temperature.
Any in compression process the efficient of the hot machine of not heat release can not reach Carnot Cycle's Efficiency.
10. be to the heating process of working medium with to the difference of the compression process of working medium: heating process necessarily produces superfluous temperature, and compression process is quite different.
About ten of the second law of thermodynamics new elaboration modes, be of equal value, also can be through mathematical proof, any one in these ten elaboration modes all can be used separately.Inventor's suggestion: in the thermodynamic study process, answer extensive use out-of-phase diagram and above-mentioned new elaboration mode about the second law of thermodynamics.Out-of-phase diagram and about the new elaboration mode of the second law of thermodynamics exploitation to thermodynamic (al) progress and high efficiency thermal machine is significant.
The English expression of the new elaboration mode of the second law of thermodynamics:
1. It is impossible to return a heat rejection process to its initial state without a heat injection process involved.
2. It is impossible to return a heat injection process to its initial state without a heat rejection process involved.
3. It is impossible to return a non-adiabatic process to its initial state without a non-adiabatic process involved.
4. It is impossible to return a non-adiabatic process to its initial state only by adiabatic process.
5. If the final pressure of heat injection process is returned to its initial pressure by process other than heat rejection process, the temperature of that state is higher than that of the initial state.
6. If the final pressure of heat rejection process is returned to its initial pressure by process other than heat injection process, the temperature of that state is lower than that of the initial state.
7. It is impossible to make heat injection process not generate excess-temperature.
8. It is impossible to make heat rejection process not generate insufficient- temperature.
9. It is impossible for any device that operates on a cycle to reach the efficiency indicated by Carnot cycle without heat rejection in compression process.
10. The difference between heat injection process and compression process which are applied to working fluid of thermodynamic process or cycle is that heat injection process must generate excess-temperature, but compression process must not.
Among the present invention, should necessary parts, unit or system etc. be set in the place of necessity according to the known technology in heat energy and power field.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, efficient is high, the low long service life of cost.
