摘要
Abstract
Through the research,analysis and calculation of boiler efficiency and pipe network trans-mission heat efficiency,combined with the standard da-ta in the third step of energy-saving and the expecta-tions for the fourth step of energy-saving,the target in the fourth step of energy-saving for residential buildings in Heilongjiang Province has been determined:The fourth step is to save 30％energy compared to the standards in the third step of energy-saving in Hei-longjiang Province.Taking multi-story buildings in Harbin as an example,according to the coal consump-tion index for heating when it is not energy-efficient,the heating heat consumption index is calculated,and the total energy-saving rate of multi-story buildings in Harbin relative to non energy-efficient buildings is 72.4％,and the energy-saving rate of buildings is 57.1％.For 10 typical cities in Heilongjiang Prov-ince,the heating heat consumption index and energy-saving rate of various buildings are calculated accord-ing to Harbin's algorithm.The average total energy-sav-ing rate under the fourth step of energy-saving in typi-cal cities in Heilongjiang Province is calculated to be 72.7％,and the average building energy-saving rate is 57.6％.The limit values of heat consumption index for heating various types of buildings in the fourth step of energy-saving in other cities in Heilongjiang Province are calculated.All cities basically have been met the standards in the fourth step of energy-saving,but over-all they have not been reached the theoretical energy-saving rate of 75％.关键词
