在实际已建建筑中,能源浪费巨大,大部分既有建筑不满足节能标准。尤其是高校建筑这种占地面积大、人员多、用能系统复杂的综合园区,能源消耗上存在着巨大的浪费。在节能改造中,根据建筑周围情况使用低品位能源热泵机组,如污水源、空气源、地热能等。并且可以联合太阳能进行耦合运行,达到清洁能源利用最大化。 In the actual construction has been built, a huge waste of energy, most of the existing buildings do not meet the energy efficiency standards. Especially in university buildings, this kind of integrated campus covers a large area, has many people and can be complex in system. There is a huge waste of energy consumption. In the energy-saving retrofit, low-grade energy heat pump units are used according to the surrounding conditions of buildings, such as sewage sources, air sources and geothermal energy. And can be combined with solar energy coupling operation, to maximize the use of clean energy.
