| Building type | Primary active state | Activity metabolic rate M (met) |
| House | Sit quietly | 1.2 |
| Office | Sit quietly | 1.2 |
| Market | Walking | 1.6 |
Step 4：Data processing module judges Building Cooling Source Type behaviour work in current indoor thermal and humidity environment type parameter
Cooling and Heat Source is built, and according to the Indoor Thermal Environment parameter and building relevant parameter detected, asks for estimated average hotness and pre-
The dissatisfied percentage of meter, and draw the grade of current thermal and humidity environment；Calculate and provide prediction thermal neutral temperature and most of residents
Thermal comfort temperature scope.
Estimated average hotness PMV calculation formula is：
Wherein, exp (i)=ei；M is the activity metabolic rate；The mechanical work that W is done by human body, value is 0；PaFor environment
Steam partial pressure,taFor the indoor air temperature, H is indoor air relative humidity；fclFor
The area coefficient of clothes,IclFor clothing thermal resistance；tclFor clothes hull-skin temperature,For
Indoor mean radiant temperature, hcFor convection transfer rate,V is

It is expected that dissatisfied percentage PPD calculation formula is：
PPD=100-95exp [- (0.03353PMV4+0.2179PMV2)]；
By the estimated average hotness PMV calculated in data processing module and it is expected that dissatisfied percentage PPD and standard
Value is contrasted, and the grade of current thermal and humidity environment is drawn according to table 3：
Thermal and humidity environment level evaluation standard under the artificial Cooling and Heat Source environment of table 3
Current indoor predicts that the computational methods of thermal neutral temperature are：In the calculation formula of the estimated average hotness PMV,

When, calculate obtained indoor air temperature taFor upper limit air themperature ta2；[ta1,ta2] formed temperature range be thermal comfort
Temperature range.
Step 5：Data processing module judges that Building Cooling Source Type is inhuman in current indoor thermal and humidity environment type parameter
Work Cooling and Heat Source is built, and according to the Indoor Thermal Environment parameter and building relevant parameter detected, asks for estimated adaptability evenly heat
Feel, and draw the grade of current thermal and humidity environment, and calculating is provided.
It is expected that the average hotness APMV of adaptability calculation formula is：
APMV=PMV/ (1+ λ PMV)；
Wherein, λ is adaptation coefficient；
It is theoretic that PMV is built upon steady-state heat balance, it is believed that human body is the passive recipient of thermal environment or thermostimulation, and
Positive be adjusted will not be acted on by the feedback cycle of people-environmental system.It can be seen that, PMV models do not account for human body
Adaptability, but this adaptability has a significant impact to Subjective Thermal Feeling.The field research result of thermal comfort is found, is set up
In hotness when have estimated human body in high temperature that the PMV on the basis of thermal balance model is too high, while too low have estimated low
Hotness when warm.And under unartificial Cooling and Heat Source environment, what people can feel carries out adaptability by way of adjusting clothing
Regulation, actively to deacclimatize environment.PMV does not consider this influence.So causing inclined with human body Subjective Thermal Feeling AMV
From.Then, adaptation coefficient λ proposed by the present invention is used to compensate the average hotness AMV of human body subjectivity and prediction and evaluation hotness
PMV difference.
λ computational methods are as follows：
Different temperatures in the unartificial Cooling and Heat Source environment of any one in being built using hotness voting method (TSV)
Under, the training sample for including the actual hotness ballot value of human body of several personnel；According to the corresponding room of each training sample
Interior thermal and humidity environment parameter calculates the corresponding pmv value of each training sample with building relevant parameter；The actual hotness of each human body
Ballot value is corresponded with each PMV, if training sample is 10000 people, just there is 10000 groups of PMV and the actual hotness of human body
Ballot value is matched.The pmv value of all training samples is divided according to default branch mailbox interval；Such as branch mailbox at intervals of
When 0.25, it is (- 0.5, -0.25), (- 0.25,0), (0,0.25), (0.25,0.5) etc. to be divided interval, and branch mailbox interval is by instructing
Practice sample size to determine.Therefore, being each divided interval just has multigroup PMV and the actual hotness ballot value pairing of human body.Statistics
The actual hotness ballot value of human body and pmv value of training sample in the interval being each divided, and this is calculated respectively
The actual hotness ballot value of human body and PMV average value of training sample in interval, the wherein actual hotness ballot value of human body
Average value is AMV；Using branch mailbox method (BIN methods) to the flat of the average value AMV and PMV of the actual hotness ballot value of all people's body
Average is smoothed；Average value using each PMV for being divided interval is divided in interval as independent variable positioned at this
The average value AMV of the actual hotness ballot value of human body sets up below equation as dependent variable：
Wherein, xiFor the average value for the PMV for being divided interval, yiFor the actual thermal sensation of human body being divided positioned at this in interval
Feel the average value AMV of ballot value；
λ value when trying to achieve Π minimums using least square method；
The reason for using BIN methods：
1) it is discrete magnitude using the TSV actual hotness ballot values of human body obtained, continuous quantity can be obtained using BIN methods,
What is so showed on the diagram is more directly perceived.
2) APMV is a prediction to average in itself, data is smoothed using BIN methods, to a certain degree
The meaning for having reacted average.
3) handled using the branch mailbox method training sample larger to quantity, it is few to obtain quantity, most representational human body
The average value AMV and PMV of actual hotness ballot value average value, reduce the data volume that follow-up least square method is calculated.
The average hotness of the estimated adaptability calculated in data processing module is contrasted with standard value, according to table 4
Draw the grade of current thermal and humidity environment：
Thermal and humidity environment level evaluation standard under the unartificial Cooling and Heat Source environment of table 4
| Grade | Overall evaluation index (APMV) |
| I grade | -0.5≤APMV≤+0.5 |
