本文介绍了一种用于鸡舍的新型地源热泵系统，该系统是由混合光伏太阳能系统构成的。农民倾向于不使用地源热泵，因为挖掘和时间消耗的价格很高。本研究评估的创新热泵系统包括一种新型热交换器；安装在屋顶瓦片和光伏电池板之间的薄管太阳能聚乙烯热交换器，以及利用土壤中储存的热量的新型立式地下热交换器。在英国柯顿，应用于禽舍的供暖系统在各种环境和运行条件下进行监测和评估，以实现供暖系统的年度/长期效率。确定了鸡舍的最大采暖需求为34.4 MWh/PC，最小采暖需求为11.1 MWh/PC。监测结果表明，该热泵系统每年可产生15.02兆瓦时的热能。太阳能光伏和热泵与太阳能光伏很好地结合在一起，覆盖了热泵每年的所有电能需求，并产生了8.74兆瓦时的额外电力输出到电网。一年的绩效季节系数为3.73。新型PVT-地源热泵供暖系统是一种非常有前途的解决农业高化石燃料消耗的解决方案，整个系统的节能效果依赖于系统的控制而显著增加。
The case study presented in this paper is an innovative ground source heat pump (GSHP) system constituted by a hybrid Photovoltaic Thermal (PVT) solar system for poultry houses. Farmers tend to not to apply GSHPs because of the high prices of excavation and time consumption. The innovative heat pump system assessed in this study comprises of a new type of heat exchangers; a thin-tube solar polyethylene heat exchanger installed between roof tiles and PV panels and a novel vertical ground heat exchanger to utilize the heat stored in the soil. The heating system applied to a poultry house are monitored and evaluated under a variety of environmental and operating conditions to achieve annual/long-term efficiency of the heating system in Kirton, UK. The maximum heating demand of the poultry house is determined 34.4 MWh/PC while the minimum is 11,1 MWh/PC. The monitored results show that the heat pump produced 15.02 MWh of thermal energy per annum. Solar PV and heat pump worked very well together with solar PV covering all the heat pump’s annual electrical energy requirement and generated 8.74 MWh of extra electricity exported to the grid. The seasonal coefficient of performance is found 3.73 through a year. The novel PVT-GSHP heating system is a very promising solution for high fossil fuel consumption in the agriculture industry and the energy savings of the whole system can be noticeably increased dependent up on the system controlling.
