I have got the following information: Clo - Clothing and Thermal Insulation Clo is used to measure the thermal insulation of cloths Cloth's insulation are normally measured with the unit "Clo", where 1 Clo = 0.155 mēK/W
If there is a manikin whose heat flux is 10w/m2, and the insulation value of the clothes is 0.5 Clo ,then when we compute the heat transferred to the environment from the manikin , how should we do? What's the function of this parameter in the computation? thx |

Clo is an inverted heat transfer coefficient.
Qdot (W/m^2) = 1/Clo (T_manikin - T_ambient) The temperature rise between the manikin and the environment for your example would be 1.55 degC. Robin. |

Mr.Robin: according to the equation you gave, and in my example I set the insulation value to be 0.5 Clo, the temperature between the manikin and the environment should be 10*0.155*0.5=0.775 degC, not 1.55degC, right?
