Indoor human thermal comfort environment requirements and evaluation methods
1 Scope
This standard specifies the technical requirements and evaluation methods for the indoor human thermal environment.
This standard is applicable to the design and evaluation of indoor thermal environment under moderate heat conditions for daily work and life, and can also be used for room air conditioning
Evaluation of system thermal comfort. Cinemas, hospitals and other special conditions of human thermal comfort environment requirements can refer to the use of this standard.
