冷凝热回收系统经济分析
摘要
空调系统无论是哪种形式的空调(风冷冷水、水冷冷水或家用分体空调)当它运行时总是有相当多的冷凝热(在制冷工况下运行,~)[] 直接排入大气,白白散失掉,造成较大的能源浪费,并且仍然存在对周围环境的热污染。从节能的角度看,建筑节能可采用改善围护结构蓄热特性形式。但在较大型的空调系统中,无论采取什么形式,依然无法避免系统冷凝放热的浪费。而对于高层住宅建筑来说,建筑物又需要大量的生活热水供应,特别是酒店宾馆类建筑。所以添加加热设备是必要的。随着人们生活水平的不断提高,生活热水的需要量也越来越大,加热生活热水所需的能量也越来越大,如果能将冷凝热全部或部分回收来加热生活热水,不但可以冷凝热对环境造成的污染,而且还可以节省不少的能源。针对以上情况,对冷凝热回收经济性分析问题进行了探讨和比较, 以供参考。

ABSTRACT
Air conditioning system in either kind of air conditioning (air cooling water, water cold water or household fission air conditioning) when it run time always have quite a number of condensing heat (in cooling conditions run, condensation heat capacity can reach ~ times) directly into the atmosphere, in vain, scattered lost causes big energy waste, and there are still the surrounding environment of thermal pollution. From the perspective of energy saving, energy saving building palisade structure can be used to improve heat storage capacity form. But in the larger air conditioning system, no matter what form, will not be able to avoid system condensing heat emission of waste. For high-rise residential building for, building and need a lot of domestic hot water supply, especially the hotel buildings. So add heating equipment is necessary. As people living standard rise ceaselessly, the life of the hot water demand too more and more big, living hot water heating for energy and is more and more big, if can all or part of the condensing heat recovery to heating domestic hot water, not only can condensation heat to environmental pollution, but also can save a lot of energy. In view of the above situation,
the condensing heat recovery efficiency analysis are discussed pared, for reference.
