Statistical Analysis for Temperature Sensor Data

The field measurement of thermal comfort was conducted in experimental living room with five or six respondents. The four-thermostat setting of air-conditioning was applied in this measurement. Each thermostat setting was repeated four times.

Part 1: Compiling raw data

The number indicates the observation data of room air temperature, relative humidity, globe temperature, and air velocity of several sensors with ten seconds interval in experimental living room.

• Data for temperature and relative humidity: The columns are: (1) Number of sampling; (2) date; (3) time; (4) temperature of sensor; (5) relative humidity (RH); (6) air temperature (Ta); (7) globe temperature (Tg).

• Data for air velocity: The columns are (2) time and (3) air velocity.

Part 2: Calculating the average, standard deviation, maximum, and minimum for all variables

Formatting: One decimal point for all variables except relative humidity is no decimal point. Results are printed to file##.csv.

Part 3: Calculating the mean radiant temperature (Tmrt) and operative temperature (Top)

Mean radiant temperature (Tmrt) can be estimated using the following equation:

where ε refers to emissivity of the globe, taken as 0.95 for a black globe, and D is the diameter of the globe which is fixed at 0.04 m.

Top is approximated as follows:

At indoor condition when average of air speeds is less than 0.20 m/s, Top is approximated with following equation:
