Measurement of Thermal Comfort and Discomfort

摘要

Comfort criteria have been discussed, which by measurement, form the basis for determination of the expected thermal comfort. The disadvantages of traditional measuring instrumentation are pointed out and a better method is suggested for determination of a person's expected degree of general thermal comfort. The lack of basis for a corresponding precise evaluation of the local comfort problems due to asymmetric radiation or draught is discussed. A couple of new parameters are given which, together with the existing knowledge, is deemed to give the best possible estimation or the degree of expected thermal discomfort due to assymetry of the thermal field. Finally, a new instrument is described which can analyse thermal environments as well as measure these new parameters. (ERA citation 10:031267)
