The potential for energy, carbon dioxide equivalent (CO₂e) and cost savings when using low emissivity (low-ε) transpired solar collectors (TSCs), combined with heat pumps in a range of configurations, has been investigated using computer modelling. Low-ε TSCs consist of metal solar collector plates with a spectrally sensitive surface, perforated with holes. Ambient air is drawn through the holes and heated by convection from the solar collector plate, increasing the air temperature by up to 25 K. The heated air can be used for e.g. space heating, or pre-heating water in buildings. The models developed have been used to compare the performance of low-ε TSC/heat pump heating systems in small and large buildings, at a range of locations. The model results showed savings in energy, CO₂e and costs of up to 16.4% when using low-ε TSCs combined with an exhaust air heat pump compared with using the exhaust air heat pump alone.

Practical application: If the UK is to meet its target of reaching net zero greenhouse gas emissions by 2050, it will be necessary to adopt low or zero carbon heating technologies. The novel low emissivity transpired solar collector device investigated can contribute to this. Its advantages include: (i) utilising solar radiation; (ii) readily integrated with existing heating systems e.g. heat pumps; (iii) significant energy, CO₂e emissions and cost savings; (iv) low cost device; (v) minimal energy input i.e. one small fan; (vi) can be retrofitted to existing buildings; (vii) its benefits were applicable at all of the (wide range of) locations tested.

使用计算机模型研究了使用低发射率（低ε）蒸发型太阳能集热器（TSC）并结合热泵的一系列配置中潜在的能量，二氧化碳当量（CO ₂ e）和成本节省。低εTSC由具有光谱敏感表面并带有孔的金属太阳能集热板组成。周围的空气从孔中抽出，并通过对流从太阳能集热板上加热，从而使空气温度升高多达25K。加热的空气可用于例如空间供暖或对建筑物中的水进行预热。所开发的模型已用于比较各种位置的小型和大型建筑物中低εTSC /热泵供暖系统的性能。模型结果表明节省了能源，CO ₂与仅使用排气热泵的情况相比，将低εTSC与排气热泵结合使用时的成本和成本高达16.4％。

实际应用：如果英国要实现其到2050年实现温室气体净排放量零排放的目标，则必须采用低碳或零碳供暖技术。被研究的新颖的低辐射率透热式太阳能收集器装置可以对此做出贡献。它的优点包括：（i）利用太阳辐射；（ii）易于与现有的加热系统（例如热泵）集成；（iii）大量的能源，CO ₂ e排放量和成本节省；（iv）低成本设备；（v）最少的能量输入，即一个小风扇；（vi）可以翻新到现有建筑物；（vii）它的好处适用于所测试的所有（范围广泛）位置。
