| 中文摘要: |
| 地源热泵是一种利用土壤所储藏的太阳能资源作为冷热源进行能量转换的供暖制冷空调系统,通过输入少量的高品位能源(如电力、机械功、燃气和液体燃料),实现热量从低温热源向高温热源的转移.以上海某小型别墅为对象,设计了一套家用地源热泵空调系统.首先计算了夏季冷负荷和冬季热负荷,然后根据冷、热负荷选择一套水源热泵机组(MWH080CR型机组)和相应的风机盘管,进行了室内水管环路系统、土壤热交换器和地板采暖的设计选型,最后对系统的能效比进行了计算.结果表明,该空调系统具有节能环保、稳定可靠、舒适耐用等优点. |
| 英文摘要: |
| Ground source heat pump uses the solar energy stored in soil as a heat source for heating and refrigeration.This air conditioning system was operated through the import of a small number of high-grade energy (such as electricity,mechanical power,and gas or liquid fuels) to transfer this heat from low temperature heat source to high temperature heat source.The design of a ground source heat pump system for a small villa in Shanghai was described in this paper.Firstly,the cooling load and the heating load of the villa were calculated.Secondly,a water-source heat pump (Integrated horizontal MWH008CR,McQuay Air Condition Ltd model) and its corresponding fan-coil units were chosen.Thirdly,the indoor water-pipe loop system,ground source heat exchanger,and floor heating system were designed and their corresponding water pumps were selected.At last,energy efficiency of this system was calculated.It could be concluded that this ground source system has the merits of energy saving,environmental protection,high reliability,comfortability,and durability. |
