Abstract


Building energy consumption in China's energy consumption , the proportion of total energy consumption is 20% to 25% of the heating energy consumption accounted for more than half of the building energy consumption , therefore particularly important to the economic and energy-saving operation of the heating system . Of heating various forms the small hands burning of this study , in minicomputer directly connected to the heating system fired low temperature hot water throughout the warm period of economic and energy-saving operation in the heating period from 2006 to 2007 with an operating company in Harbin research cooperation project . Key research project of heating systems : heating run according to meteorological parameters scientific guidance ; constantly monitoring the indoor temperature , the sampling rate is greater than 20% , in order to ensure that the heating effect ; improve the efficiency of the heat source ; adjust the hydraulic balance of the heating network ; heating system the regulation : to strengthen the entire system of insulation to reduce the heat loss of the heating system is running . Economic energy-saving operation after a heating period , access to information, data on the heating system . While addressing many of the ills of the heating system , to improve the operating conditions of the heating network and experience accumulated energy-saving operation of heat supply network . Directly connected to the district heating system for small and medium - sized low-temperature hot water ; courtyard small hand-fired low-temperature hot water heating system statistics and processing throughout the heating period , and coal consumption , water consumption , electricity consumption equivalent to the specification at room temperature and the outdoor standard temperature equivalent heating period of 180 days , respectively, equivalent to the data . This article for a more in-depth study of the current prevalence of Northeast China 's small and medium- low temperature hot water heating systems economic and energy-saving operation directly connected , the data and conclusions drawn universal significance . The methods used and the conclusions for similar heating system of the northeastern region reference .
