Embodiment

[0044] The present invention provides a novel thermal comfort model that can comprehensively account for thermal adaptation and thus more accurately predict thermal comfort. The method for building thermal comfort model of the present invention comprises three steps (as figure 1 shown): the first step is to preprocess the collected PMV, TSV and ambient temperature T data sets so that both PMV and TSV are greater than zero (such as formulas 12 and 13); the second step is to use the collected ambient temperature T and the pre-prepared dealt with Calculate the constant parameters q and p according to formulas 14 and 15 respectively; in the third step, use the obtained constant parameters q and p to construct the thermal comfort model naPMV according to formula 16.

Abstract

The invention discloses a thermal comfort modeling method based on a changed adaptability factor and a predicted average voting value. According to a formula: constructing a thermal comfort model naPMV, wherein in the formula, lambda is an adaptability factor and linearly changes along with the reciprocal of the environment temperature T, p and q in the formula are constant parameters and are calculated according to the following formula: (shown in the description) PMVi, TSVi and Ti in the formula are the ith thermal sensation prediction average voting value, the thermal sensation actual average voting value and the environment temperature which are collected in field research respectively; collecting n PMV, TSV and environment temperature T data sets in total, wherein PMVi and TSVi are respectively a thermal sensation prediction average voting value and a thermal sensation actual average voting value which are greater than zero after being preprocessed. According to the method, an adaptability method and an inference method are combined, and changed adaptability factors are introduced into an inference method model PMV, so that a new thermal comfort model naPMV is constructed. ThenaPMV model improves the thermal adaptation explaining capability of the model PMV, and can predict the thermal comfort more accurately and reliably.

Description

technical field [0001] The invention relates to the field of indoor thermal comfort prediction, in particular to a thermal comfort modeling method based on changing adaptability factors and predicted average voting values. Background technique [0002] Thermal comfort is one of the important indicators to evaluate the quality of indoor environment, which affects the health and work efficiency of indoor personnel. Thermal adaptation is defined as a phenomenon in which the human body gradually reduces its response to repeated thermal environmental stimuli, including three aspects: physiology, psychology, and behavior. When thermal environment changes cause thermal discomfort, thermal adaptation helps the body to restore thermal comfort. [0003] Thermal acclimatization can broaden the thermal comfort zone, thereby contributing to energy savings. According to the thermal comfort standard ASHRAE 55, thermal acclimatization can raise the upper limit of acceptable indoor tempera...
