Thermodynamic evaluation of a climate according to energy requirements of microclimate conditioning systems

Abstract

The problem concerns thermodynamic analysis of microclimate conditioning systems when it's effectiveness is defined by features of climate only. Index for effectiveness as well as equations for it's calculation and notion "energy degree days" are proposed. The index evaluates minimum of energy required for heating at certain locality and supposes possibility too evaluate effectiveness of a system inseparably from the climatic conditions of the locality. Cumulative duration of the temperature difference for heating season is determinated on the basis of annual average days temperatures Tmax, Tmin, Tm.
