摘要：    随着科技的发展，越来越多的技术将应用到空调的节能中来。地源热泵技术在别墅小区的安装中大大体现了它节约能源的优势，这项技术是符合国家关于节能减排的政策的。本课题在分析地源热泵空调系统节能优势的基础上，对南京某独栋别墅的地源热泵中央空调系统进行设计，能够满足夏季制冷、冬季供暖的要求。由于南京属于夏热冬冷地区，热泵设计应以夏季降温为主，兼顾冬季供暖，而一般地下管群的传热量冬季大于夏季，因此夏季能满足要求，冬季一般也能达到要求，故本装置按夏季工况设计。本设计首先根据设计条件进行建筑冷热负荷的计算，其次对建筑物的风系统、水系统进行设计和设备选型，再对地板采暖和地埋管换热器进行计算和选型，最后兼顾建筑物的消声和减振。9328

Design of a villa ground-source heat pump central air conditioning system
Abstract:     With the development of science and technology, more and more technology will be applied to air-conditioning energy saving. Ground source heat pump technology in the villa district installation greatly reflects its advantages of saving energy, this technology is in line with the national policy on energy saving and emission reduction. This paper based on analyzing the advantage of energy-saving ground-source heat pump air conditioning system, for the design of ground-source heat pump central air conditioning system in a villa in Nanjing, which can meet the summer cooling and winter heating requirements. Because Nanjing is hot in summer and cold in winter, heat pump should be designed with both summer cooling and heating in winter, and the heat transfer from the general underground pipe group is higher in winter than in summer, if it can meet the requirements of general summer then winter can also meet the requirement, so the device according to the summer condition design. The design, building heating load calculation based on the design conditions, followed by the building's air system, water system design and equipment selection, calculation and selection of floor heating and ground heat exchanger, and finally take into account thethe muffler and damping of the building.
