CONFORTEl confort térmico, definido en la norma ISO 7730, es “la condición de
la mente que expresa satisfacción con el ambiente térmico”. Este
confort solo se da cuando la temperatura de la piel es estable dentro
del rango 31,5° C y 34,5°C (Cengel, 1998, pág. 709), y la temperatura
del cuerpo está en 37 °C. Estas condiciones a su vez dependen de
factores internos (metabolismo) y externos (vestimenta; temperatura,
humedad relativa, velocidad del aire e intercambio radiante con los
alrededores).

Measuring Radiant Temperature Radiant temperature is usually measured with
what it known as a globe thermometer. This is simply a normal dry bulb
thermometer encased in a 150mm diameter matte-black copper sphere whose
absorptivity approaches that of the skin. Hence MRT is sometimes referred to
as globe temperature (GT) as they are nearly equivalent.
