Now only one thin ideal gas layer in the box needs to be examined, how to establish the differential equation? At equilibrium, the gas in the frame neither floats nor sinks, and the buoyancy force is equal to the gravity. And buoyancy is the pressure difference between the upper and lower surfaces. Now only the relationship between pressure and density can be found out. As you know, the ideal gas state equation is: pV ═ nRT, where n is the number of moles. Note that here is the pressure of each thin layer in relation to the height. Although the ideal gas equation is not used in general for homogeneous gravity fields, it is also true for a thin layer of the same height in weak gravity fields. From this equation of state, it can be seen that the "local pressure" of an ideal gas is not directly related to the "mass density", but is directly related to the "molar density". To obtain the relationship between pressure and density, the molecular weight or "molar mass" of the ideal gas, not set to M, must be known, so that: ρ Mp/RT, and now, according to the law of buoyancy, there are: -dp ═ (Mpg/RT) dz; that is, the differential equation in this form, the integration on both sides yields that the pressure of the single-component ideal gas decreases exponentially with the height, and the larger the molecular weight (molar mass), the larger the (equivalent) gravitational acceleration, and the faster the temperature decreases. Then how should one treat for the subject multi-component system? As a zero order approximation we also consider only the ideal gas. Thus, we have the law of dalton partial pressure, which means that in practice the components of an ideal gas are "transparent" to each other, self-balancing with themselves. Therefore, it is only necessary to interpret the "gas pressure" in a single component of the desired gas as the "partial pressure of the components". That is, for any two desired gas components, there are: determining the partial pressure at 0 altitude also requires other constraints, such as the ratio of the total moles of the two gases, etc. It is clear, however, that unless the molecular weights of the two components are the same, their partial pressure ratios, "molar density" ratios, "mass density" ratios, all vary exponentially with height. The main problem is nitrogen and oxygen, which have small molecular weight difference and are not very effective at normal temperature. But the difference between carbon dioxide and nitrogen and oxygen is large. If you take the ground level to zero, you know that if ventilation is not good, the carbon dioxide concentration in the deeper basement, downhole, will rise very quickly and may even be fatal enough. So compensation by a compensation algorithm is required, which takes into account temperature, humidity, oxygen content and carbon dioxide content.
The air supply system comprises a fresh air subsystem, a regulation subsystem and a basement, wherein the fresh air subsystem is used for outputting air to the basement after the fresh air subsystem extracts air from the basement according to the air displacement. And the first preset number of times may be set to 5 times and the first preset time may be set to 60 seconds.
The model comparison step satisfies a first predetermined relationship, where V is an air displacement, V1 is a volume of the first air, V2 is a volume of the second air, V3 is a volume of the third air, and V4 is a volume of the fourth air. The internal air pressure is firstly ensured to be stable, so that the exhaust amount and the air inflow are required to be ensured to be the same.
The model comparison step satisfies a second predetermined relationship, which is a V1 ═ VS (a1-a2) + (VS-V)2*a*(D2-DY)2Wherein A is oxygen content, VS is total volume of equivalent air of the basement, A1 is reference oxygen content, A2 is sampling oxygen content, a is preset oxygen content adjusting parameter, D2 is sampling temperature value, and DY is preset reference layered temperature value. And this stepFirstly, the oxygen intake device is used for controlling and generating air with higher oxygen content, and in order to correct errors caused by sampling positions to the result, the actual temperature value is shifted, namely, the lower the temperature is, the more obvious the layering condition is, and the less the discharged oxygen is, after the air discharging operation, the oxygen content of the discharged part of air needs to be considered, so that an accurate air discharging effect can be achieved.
The model comparison step satisfies a third predetermined relationship, where the third predetermined relationship is B × V2 ═ VS (B1-B2) -V2*b*(D2-DX)2(ii) a B is carbon dioxide compensation amount, VS is total volume of equivalent air of the basement, B1 is reference carbon dioxide content, B2 is sampling carbon dioxide content, B is preset carbon dioxide content adjusting parameter, D2 is sampling temperature value, and DX is preset reference layering temperature value. This step is first compensated by carbon dioxide to obtain a value of carbon dioxide having a high concentration, and as in the above conclusion, the concentration of carbon dioxide to be discharged needs to be taken into consideration, so that the carbon dioxide content needs to be supplemented.
The model comparison step satisfies a fourth preset relationship, where the fourth preset relationship is (CY-C) × V3 ═ C × VS (C1-C2), where C is a humidity compensation amount, CY is a preset standard humidity value, VS is a total volume of equivalent air in the basement, C1 is a reference humidity value, C2 is a sampling humidity value, and C is a preset humidity adjustment parameter. The humidity adjustment effect is similar to the temperature adjustment effect.
The model comparison step meets a fifth preset relationship, and the fifth preset relationship is (DY-D) V4 (D VS) (D1-D2), wherein D is a temperature compensation quantity, DY is a preset standard temperature value, VS is the total volume of equivalent air of the basement, D1 is a reference temperature value, D2 is a sampling temperature value, and D is a preset temperature adjusting parameter. In addition, V1: v2: v3: v4 is preferably 1:1:10: 9. Therefore, a better adjusting effect can be achieved, and the requirement of a preset concentration model can be met finally through a multi-time respiration algorithm.
The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all the technical solutions formed by equivalent substitutions or equivalent changes are within the scope of the present invention as claimed.
