Therefore, removing the indoor / outdoor temperature influence factor deviation coefficient can improve the accuracy of indoor temperature measurement. If no indoor / outdoor temperature influence factor deviation coefficient exists, then the standard value of indoor temperature is... The formula then becomes , The value is 1.

The scaling factor coefficients are used to correct for deviations in the calculation of various parameters, thereby making the calculation results more accurate. Equals 1, It can take the value 0.635. It can take the value 0.365.

[0011] Preferably, the indoor temperature assessment index The analysis process is as follows: Based on the size, shape, and partitions of the indoor space, multiple temperature detection points were designed, spaced two meters apart.

[0015] Preferably, the indoor humidity standard value The specific calculation method is as follows: , This is the humidity correction factor. This refers to the hygroscopic properties of wood materials. Specifically, when measuring indoor humidity, it is generally related to indoor temperature. For example, as the temperature rises, the air can hold more water vapor, so the relative humidity decreases; conversely, as the temperature decreases, the relative humidity increases. Relative humidity refers to the percentage of actual water vapor content in the air compared to the maximum water vapor content that air can hold at the same temperature. Therefore, a humidity correction factor is used. With humidity measurement value The standard value of indoor humidity can be obtained through calculation. ; Indoor humidity is also affected by the hygroscopicity of indoor decoration materials, so the hygroscopicity parameter of wood materials also needs to be added.

The saturated vapor pressure of the initial temperature measurement is then marked as... The temperature and humidity control module marks the saturated vapor pressure of the temperature value after temperature adjustment as follows: ; ; Saturated vapor pressure refers to the partial pressure of water vapor in the air when it reaches saturation at a given temperature.
