地源热泵作为一种大幅度降低住宅能耗的手段，显示出巨大的前景。通过使用地表以下6到600英尺之间的土壤作为热能源或热阱，可以获得4到6英尺范围内的加热和冷却性能设计系数。此外，家庭热水的产生是家庭能源消耗的重要来源。随着用于空间加热和冷却的能源减少，减少用于热水发电的能源成为下一个目标。使用减温器来产生生活热水是一种潜在的策略，通过使用来自空间调节系统的热泵来产生热水，而不是电阻或化石燃料，从而降低能耗。 然而，在建议广泛实施之前，有必要了解影响减温器热能输出的元件（如热泵运行时）的影响程度。佐治亚州松山的两栋无人居住的房屋被安装了仪器，以记录其地源热泵系统的安装运行空间调节和水加热效率。监测期从2010年1月开始，一直持续到2011年4月。在此期间，室内恒温器的加热和冷却设定点一直保持在恒定值，并且计划的热水消耗量根据美国使用的入住率曲线表进行。 美国能源部的美国建筑项目。本文将讨论两台地源热泵的仪表方法和现场运行特性，包括与制造商根据两台地源热泵的现场测量数据计算出的性能系数的列表值进行比较。减温器辅助家用热水系统的测量效率将与其他市场上可用的家用热水系统进行比较。引文:伊利诺伊州芝加哥ASHRAE会议论文

Ground source heat pumps show great promise as a means to substantially reduce house energy consumption. Through the use of the soil between 6and 600 feet below the surface of the earth as the thermal energy source or sink, it is possible to obtain design coefficients of performance for heatingand cooling in the range of 4 to 6. Furthermore, generation of domestic hot water is a substantial source of energy consumption in a house. Asenergy for space heating and cooling decreases, reducing energy for hot water generation becomes the next target. The use of a desuperheater forgenerating domestic hot water is a potential strategy to reduce this energy consumption by using the heat pump from the space conditioning system tocreate hot water instead of electric resistance or fossil fuel. However, before widespread implementation can be recommended, it is necessary tounderstand the magnitude of the impact of the elements that affect the thermal energy output of the desuperheater, such as heat pump runtime. Twounoccupied houses in Pine Mountain, Georgia, were instrumented to document the installed operational space conditioning and water heatingefficiency of their ground source heat pump systems. The monitoring period began in January 2010 and continued through April 2011. Duringthis period, interior thermostat setpoints have been maintained at constant values for heating and cooling, and scheduled hot water consumptionoccurred according to the occupancy profile schedule used in the U.S. Department of Energy's Building America Program. This paper will discussthe instrumentation methods and field operation characteristics of the two ground source heat pumps, including a comparison to the manufacturers'listed values of the coefficient of performance calculated from field measured data for the two ground source heat pumps. The measured efficiency ofthe desuperheater assisted domestic water heating system will be compared to other market available domestic hot water systems.
