Investigation into the Adaption of PMV to Evaluation of the Medical Staff in Hospitals in Guangzhou

Abstract

In this investigation, the measurement thermal parameters and thermal comfort field survey were carried in six air-conditioned hospitals in Guangzhou. A total of 114 valid questionnaires were collected. Based on the data, there were strong linear regression relationships between PMV and MTSV and operative temperature. The neutral temperature was 24.39 °C from the linear regression of MTSV. The thermal comfort temperature which meets a satisfaction degree of 90% or 80% ranges from 22.83 to 25.94 °C, 21.74 to 27.03. In addition, the neutral operation temperature was 23.75 °C from the PMV model. The thermal comfort temperature which meets a satisfaction degree of 90% or 80% ranges from 22.00 to 25.50 °C, 20.77 to 26.73. Comparing the MTSV and PMV, the MTSV was lower than that of PMV. The preference Top was obtained by Probit regression analysis curve intersection point was 24.43 °C. By Actual Percentage Dissatisfaction obtains 90% or 80% of the medical staff acceptable comfort temperature upper limit of 24.71 °C, 25.53 °C.
