地源热泵（GSHP）能够通过比传统燃气系统更高效的运行来降低能耗，尤其是如果与超市等制冷设备相结合。原则上，可以利用冰箱排出的热量来提高热泵的效率。本文介绍了对这一创新系统进行操作和经济分析的结果。总的来说，考虑中的所有地源热泵系统的效率似乎都高于英国政府激励（可再生能源热激励，RHI）的资格门槛，商店的平均季节性能系数（SCOP）为3。 2014年为0。从经济角度来看，与燃气锅炉系统相比，这种平均性能每年可节省12万英镑以上的运营成本。计算表明，投资回收期（PBT）不到8年。最后，本文强调了通过操作和设计修改可以实现的潜在成本降低。总体结果表明，地源热泵加上制冷系统提供了良好的基础，被认为是食品零售商的一个有吸引力的投资机会。引用:2016年年度会议，密苏里州圣路易斯，会议论文

Ground Source Heat Pumps (GSHP) are capable of reducing energy consumption by operating at higher efficiencies than conventional gas systems, especially if coupled with refrigeration units such as in supermarkets. In principle, the heat rejected by refrigerators can be harnessed to raise the efficiency of the heat pumps. This paper presents the results of an operational and economic analysis conducted on this innovative system. Overall, the efficiency of all the GSHP systems under consideration appears to be above the eligibility threshold for the UK Government's incentive (Renewable Heat incentive, RHI), with the average Seasonal Coefficient of Performance (SCOP) of the stores being 3.0 in 2014. From an economic perspective, such average performance leads to more than £120,000 of operational savings per year compared to gas boiler systems. Calculations show an investment Payback Time (PBT) of less than 8 years. Finally, the paper highlights potential cost reductions achievable through operational and design modifications. Overall results show that GSHP coupled with refrigeration systems present sound fundamentals to be considered as an attractive investment opportunity for food retailers.
