Confort térmico en el ambiente laboral del edificio centro del GAD Municipalidad de Ambato

Abstract

The present investigative study is the evaluation of the thermal comfort in the areas with more risks of the GADMA Center Building. To analyze the current working conditions, observation and identification matrices and a survey with questions based on ISO 10551 AENOR 2002 are used, with which it is possible to identify which are the areas with the highest risk. The Fanger method (NTP 074) is used, it allows to evaluate the temperature, taking into account the temperature levels, work clothes and the metabolic rate, all of this to calculate the estimated average voting index (PMV) and the percentage of people who are dissatisfied (PPD), these data are compared with values recommended by executive decree 2393 and the UNEEN ISO 7730/2006 standard. The measurements are made using the Delta Ohm HD 32.3 equipment, with the Delta Log 10 software the calculations are developed following the measurement strategies proposed in the NTP 387, since an improvement proposal is made that can be implemented in real life. The PMV index indicates the thermal perception of the workers with a scale of 7 levels (+3 and -3), the work areas with the highest risk are not within the established range, it presents 7 jobs that represent 33% of The 21 jobs analyzed present a neutral thermal sensation, which indicates that the thermal conditions are acceptable (-1≤PMV≤0), 12 jobs, corresponding to 57%, present a slightly cold sensation (-2≤PMV≤-1). ) and 10% corresponding to 2 positions have a warm sensation (3≥PMV≥2), concluding that there is THERMAL DISCOMFORT due to heat and cold.
