It is below support with adult's thermal comfort experimental study data, following statement is made to specific implementation step:
1, a home from home parameter designing is determined based on the Subjective Thermal Feeling of personnel, then need the physiology of apparent human body first The relationship of response regulation and subjective sensation variation.Based on human body blowing experiment and questionnaire survey, for the personnel under different operating conditions Skin temperature variation and the ballot of corresponding hotness carry out average value processing, the function of the TSV and Tskin of available personnel closes System, referring to Fig. 8.
TSV=1.12*Tskin-36.89；(R2=0.95) (1)
Wherein, TSV is the hotness ballot mean value of personnel, and Tskin is the mean skin temperature of corresponding human body.
The subjective sensation variation of personnel is in a certain range preferable linear relationship with skin temperature, therefore can be preferably The comfort level of personnel under a certain environment is characterized, thus the reference index comfortably built as environmental parameter.
2, it to determine that environmental parameter designs, then need the hotness of apparent personnel and the variation relation of environmental parameter.Upper one Step has obtained the Subjective Thermal Feeling variation of the personnel under different temperatures, relative humidity, wind friction velocity based on experiment, due to personnel Hotness it is not only related to environment temperature, relative humidity, the variation of wind speed single environment variable, also with the coupling of these parameters Effect is related.Therefore, are carried out by polynomial fitting recurrence, then can obtain relational model by hotness TSV and environmental variance T, RH, V are as follows:
TSV=0.468*T+0.022*RH-0.563*V-14.079；(R2=0.96) (2)
By above-mentioned regression equation it is found that when given ambient temperature and humidity, wind speed, then it can be become with the subjective sensation of prognosticator Change.But in real life, people prefer to obtain the quantitative design parameter for the temperature and humidity wind speed for meeting comfort level requirement.This hair It is bright to carry out mainly for environment temperature and the design of suitable wind speed, since relative humidity variations are little in general indoor environment, Following selection relative humidity 60% are analyzed.
Given relative humidity level 60%, then equation can simplify are as follows:
TSV=0.468*T-0.563*V-12.759 (3)
According to " civil buildings Indoor Thermal Environment evaluation criterion ", I grades of thermal environment standards need to meet in free-running operation building 90% personnel are acceptable to indoor environment, and corresponding A PMV value is (- 0.5 ,+0.5).The range between to fix the number of workers's comfort zone In the case where TSV ∈ (- 0.5 ,+0.5), then the coupled relation model of environment temperature Yu suitable wind speed can be obtained, be respectively as follows:
As TSV=+0.5,
As TSV=-0.5,
3, obtained temperature and wind speed mathematic model are embedded in fan control program.According to equation, in known environment temperature Under conditions of, then it can calculate the wind speed range for meeting personnel's comfort requirement under respective environment.According to human comfort's wind speed demand, Here it needs according to personnel's comfort need given temperature and upper wind velocity limit: default upper wind velocity limit 3m/s, 32 DEG C of the acceptable temperature upper limit. Therefore, available temperature and wind speed under the conditions of meeting comfortable section couples section, referring to Figure 12.
