Equation is the functional relation between the saturated vapour pressure of pure material and temperature, be usually used in standard conditions fugacity, heat of evaporation, the heat of sublimation and
Balance each other association etc. calculating.
By taking water as an example, HCFC-123 alternative can be derived by Clapyron Equation, and can derive water vapour shown in Fig. 3
The relationship of air pressure and temperature.As shown in figure 3, in the case where heating device cabinet internal volume is constant, when gas atmosphere in cabinet
After being increased to certain value, the increasing value of vapor (steam) temperature can be reduced obviously with the raising of air pressure, and saturated vapour pressure is with temperature liter
It is high and increase sharply.Therefore, gas pressure intensity rises to certain value in cabinet, but setting value has not yet been reached in vapor (steam) temperature in cabinet
When, slight pressure relief suitably is carried out to the intracorporal gas of case, helps to maintain the growth of case body temperature.That is, carry out
Before slight pressure relief, control unit needs to judge whether the intracorporal barometric information of case received has had reached air pressure threshold value,

Unit processed generates micro- pressure release instruction, and is sent to pressure release unit, i.e., micro- pressure release instruction is sent to pressure release unit by control unit
Driving motor.
Step 107, pressure release unit instructs according to micro- pressure release and starts, by hot steam to set volume discharge, adjustment heating
The balance of pressure and temperature in device allows the temperature of hot steam to continue to improve, to reach preset temperature threshold.
Specifically, the relief valve in pressure release unit receives micro- pressure release instruction, it is parsed, and is referred to according to micro- pressure release
Starting is enabled, control relief valve is opened after driving motor starting, pressure release passage conducting, so that hot steam is logical with certain pressure release speed
Pressure release passage discharge is crossed, when the hot steam of discharge reaches setting volume, i.e., the intracorporal gas pressure of case reaches air pressure at this time
When threshold value, relief valve is closed.This process can be understood as the process of slight pressure relief.
Preferably, after heating unit heats the liquid in water tank, when control unit determines vapor (steam) temperature number
When according to reaching preset temperature threshold, i.e., when vapor (steam) temperature data have reached target temperature data, and heating time data are
When in object time data, control unit obtains heat preservation power according to the weight data of substance to be heated, according to heat preservation power
