在本文中，我们介绍了用于空间调节和水平地下换热器（GHX）回路水加热的地源热泵（GSHPs）的性能和效率测量指标。这些装置安装在一个345平方米（3700平方英尺）的高效试验室中，该试验室采用结构隔热板（SIP）建造，在模拟居住条件下运行，位于美国田纳西州橡树岭气候区4。本文描述了建筑围护结构、接地回路和设备的特点，并提供了地源热泵系统的详细月度性能。房子的空间调节需求得到了名义上2%的满足- 吨（7.0千瓦）水至空气地源热泵（WA-GSHP）机组，几乎不使用辅助（电阻）热量。确定了通过工程设计变更进一步改进的建议。全面的数据和分析证明了GSHPs在住宅应用中的可行性和实用性，以及其帮助实现IECC 2012标准下设定的源能源和温室气体减排目标的潜力。引用:ASHRAE Trans。，第118卷第。德克萨斯州圣安东尼奥2号

In this paper we present measured performance and efficiency metrics of Ground Source Heat Pumps (GSHPs) for space conditioning and forwater heating connected to a horizontal ground heat exchanger (GHX) loop. The units were installed in a 345 m2 (3700 ft2) high-efficiency testhouse built with structural insulated panels (SIPs), operated under simulated occupancy conditions, and located in Oak Ridge, Tennessee (USA)in US Climate Zone 4. The paper describes distinctive features of the building envelope, ground loop, and equipment, and provides detailedmonthly performance of the GSHP system. Space conditioning needs of the house were satisfied by a nominal 2-ton (7.0 kW) water-to-airGSHP (WA-GSHP) unit with almost no auxiliary (resistance) heat usage. Recommendations for further improvement through engineeringdesign changes are identified. The comprehensive set of data and analyses demonstrate the feasibility and practicality of GSHPs in residentialapplications and their potential to help achieve source energy and greenhouse gas emission reduction targets set under the IECC 2012 Standard.
