沈阳市某小别墅空调系统设计(说明书+CAD图纸+开题报告+任务书+外文翻译……)
摘要
本设计是对沈阳市某别墅的空调系统设计,设计中,结合沈阳市的气象参数、有关建筑资料、设计要求以及相关的政策,进行综合分析,最终确定经济、合理的系统方案——水源热泵系统。
水源热泵是一种使用低品位能源,如地球表面浅层水(地下水、河流和湖泊)吸收的太阳能和地热,并利用热泵原理通过少量的高电输入,以实现由地位能源到高位能源的转换的技术。
简单地说,水源热泵系统是利用地下水作为冷热“源“,在冬季,泵吸收他们的热量来为建筑物供热;在夏季,热泵吸收建筑物中的热量,传给地下水源。在不同的季节,整个循环过程仅靠改变冷凝器和蒸之间的硬件系统,我们就可以完成制冷与制热的功能转换.通常地讲,水源热泵每消耗1千瓦的能量,用户可以得到4千瓦以上能量。
本设计叙述了水源热泵系统依靠提取低品位、无污染的地下水能量,并通过采用风机盘管加新风的系统形式,实现建筑物的供热与空调。

This design is for a house air-conditioning system design,in Shenyang City.in design,combined with Shenyang meteorological parameters, the construction materials,design requirements and related policies, a comprehensive analysis,and ultimatelydetermine the economic and rational system solution - water source heat pump System.
Water-source heat pump is a technology that use the low resource of
Earth’s surface shallow water (groundwater,rivers and lakes) in absorption of solar energy and geothermal heat,and using principles of heat pump through a small number of high electric input to make low heat transfer to high heat.
Simply speaking,water cooling pump system is use of groundwater as hot and cold“source”,in the winter heat pump absorb heat from groundwater for their buildings heating;in the summer heat pump absorb heat from the buildings and liberate it to groundwater.apllication of only a hardware system,throughout transformation of a condenser and evaporate in different seasons,we can complete the conversion of refrigeration and heating functions.usually water-source heat pump consumes 1 kW of the energy,users can get more than 4 kW of heat cold.
The design describes the extraction of water source heat pump system relies on low-grade energy of groundwater pollution, and fan coil plus fresh air through the use of the system form, To achieve the building heating and air conditioning.
Keyword:Water-source heat pump system; the low resource; high heat;
fan coil plus fresh air system
