Paper Abstract

Today radiothermometers have a wide variety of applications in non-contact tememperature measurments and begin in use for estimation of heat flow and thermal resistance, in these measurements there are still some problems to be solved, in recent years we have designed a kind of enclosed radiothermometer which can be used for emissivity and temperature measurements simultaneously. Now we have established a mathemetical model of heat flow through building walls . With this model we can use the enclosed radiothermometer to measure the radiation heat flow and thermal resistance. The advantages of the measurements using enclosed radiothermometer are that the emissivity, temperature, heat flow, heat resistance can be measured only by one instrument; the measurement speed is high and the measured surface may not be thermally disturbed.
