一、引言随着我国经济发展和人民生活水平的提高,对于供冷要求日趋增大,用电量骤增,严重冲击我国的电力供应;同时,由于电力供应的紧张,限制着供冷范围的扩大。为了节约能源,提高能量的利用率,减少城市污染,我国多年来发展以大型热电厂、城市小热电站、区域锅炉房等方式,逐步实现集中供热的目标,取得可喜的成果。然而由于热负荷的不足以及热负荷的不平衡也陷入新的困境。现实给人们以启示,应该考虑在城市集中 I. INTRODUCTION With the economic development of our country and the improvement of people’s living standards, the demand for cooling is increasing day by day, and the electricity consumption is increasing rapidly, which seriously impacts our country’s electricity supply. At the same time, due to the tight electricity supply, the scope of cooling is limited. expand. In order to save energy, improve the utilization of energy, and reduce urban pollution, China has over the years developed large-scale thermal power plants, small urban thermal power stations, and regional boiler houses to gradually realize the goal of centralized heating, and has achieved gratifying results. However, due to the lack of heat load and the imbalance of heat load, it is also caught in a new predicament. The reality gives people inspiration and should be considered in the urban concentration
