Examination on Expanded AMeDAS Design Weather Data for HVAC Systems

Abstract

Expanded AMeDAS (Automated Meteorological Data Acquisition System) design weather data were developed for various locations in Japan. They were produced by selecting the extreme-weather days from Expanded AMeDAS Weather Data using two weather indices. The present paper examined the extremity of the proposed design weather data and the availability for HVAC system design. The cumulative frequencies of occurrence for several daily values of the design weather data and the probability of the thermal load exceeding the design peak load calculated using the design weather data were used for the examination and evaluation. The validity of the proposed design weather data was confirmed through the examination.
