A Proposal for Winter Outdoor Design Temperature of Intermittent Heating

Abstract

Based on the statistical method of the heating outdoor design temperature in HVAC design code, we use two calculation methods to analyze the outdoor design temperature and the heating load of some typical cities for intermittent heating . The results show that: the heating outdoor design temperature is higher 3.8 °C and 4.6 °C than that of the current standard value for long-term and short-term intermittent heating respectively, accordingly, the heating load of the long-term and short-term intermittent heating can be reduced by 9% and 15% according to the new outdoor design temperature calculated by this paper.
