Currently, there has been an obvious lack of innovation within poultry houses heating, ventilation and air conditioning (HVAC) system design that deals with both energy efficiency and poultry welfare issues. This paper presents an innovative and renewable heating system for poultry house application to meet the welfare living environment requirement for breeding, to improve the energy efficiency of HVAC system and to decrease fossil fuel consumption and harmful gas emissions. The purpose of this study is to design, develop and test the highly efficient hybrid heating system via an integrated photovoltaic/thermal array with polyethylene heat exchanger coupled to geothermal heat pump system based on the East Midlands’ climate conditions in the UK. The numerical model is established based on finite volume method and solved by using Engineering Equation Solver, and a good agreement with less than 15% difference between the numerical and experimental results is achieved. The results indicate that the annual electrical and thermal output are 11867 kWh and 30245 kWh, respectively, which not only could fulfil the poultry house electrical need, but also can provide ~43.5% electricity demand of the heat pump compressor operating.

混合可再生供暖系统在禽舍中应用的可行性：以英国东米德兰兹郡为例

当前，家禽舍的供暖，通风和空调（HVAC）系统设计中显然缺乏创新，既涉及能源效率又涉及家禽福利问题。本文提出了一种创新和可再生的供禽舍应用的供暖系统，可以满足育种的福利生活环境要求，以提高HVAC系统的能源效率并减少化石燃料的消耗和有害气体的排放。这项研究的目的是根据英国东米德兰兹郡的气候条件，通过带有聚乙烯热交换器和地热泵系统的集成光伏/热阵列设计，开发和测试高效的混合供暖系统。基于有限体积法建立了数值模型，并利用工程方程求解器进行了求解，结果与实验值相差不到15％。结果表明，年发电量和热发电量分别为11867 kWh和30245 kWh，不仅可以满足禽舍的电力需求，而且还可以提供热泵压缩机运行约43.5％的电力需求。
