Low-carbon Renewable Cooling & Refrigeration System for Public and Commercial Buildings (LoReCoRS)

**挑战和机遇：**建筑物的排放量估计高达英国总排放量的30% （BEIS， 2021年）。英国的季节性制冷需求是由办公室和零售商的降温需求驱动的，最近的夏季热浪是一个驱动因素。空调除了用于空间冷却之外，还用于超级计算机和冷藏食品的通风。在制冷方面，英国超市消耗的70%的能源用于制冷（EGB, 2021）。医院和零售店等公共和商业建筑对制冷和制冷的需求使得减少此类建筑的排放变得非常具有挑战性，因为自1990年以来，由于排放情况没有变化，缺乏整体系统方法（BEIS， 2021年）。减少公共和商业建筑因制冷和制冷而产生的排放需要一个整体的系统方法来应对这一挑战，到2050年实现净零排放。这就需要为公共和商业建筑设计低碳可再生冷却和制冷解决方案。**解决方案：**Ventairge提出了一个名为**低碳**可再生**制冷**制冷**系统的公共和商业建筑**(LoReCoRS)项目。** LoReCoRS专注于系统地开发和模拟低碳可再生冷却和制冷解决方案。该项目将包括开发一个高保真模型，该模型将以系统和整体的方式利用太阳能技术、存储模块、辅助组件和控制系统。这样的解决方案将支持未来公共和商业建筑的融合。**该系统的主要方面是：***提供可再生能源用于建筑物冷却和制冷；*利用太阳作为能源；*系统包含高存储能量密度介质；*精密的相互作用和温度平衡控制系统。**该系统提供的好处是：***它支持向公共和商业建筑的碳中和迈进；*既节能又能显著减少污染；*可实现加热与冷却的高效交互；*该系统可改善最终用户的体验、健康、安全和福祉；*可大幅减少废气排放及节省能源开支。

**The Challenge and Opportunity:**Emission of buildings is estimated to be as much as 30% of total UK emissions (BEIS, 2021). Seasonal cooling demand in the UK is driven by the need to cool offices and retailer outlets, with the most recent summer heatwave being a driver. Air conditioners in addition to space cooling, are also used for ventilation of supercomputers and chilled foods. With regard to refrigeration, 70% of energy consumed by supermarkets in the UK is utilised for refrigeration (EGB, 2021). The demand for cooling and refrigeration in public and commercial buildings such as hospitals and retail outlets, has made it very challenging to reduce emissions from such buildings due to the lack of a whole systems approach as a result of the unchanged emissions profile since 1990 (BEIS, 2021). Reducing public and commercial building emissions due to cooling and refrigeration requires a holistic system approach to the challenge, to reach net zero by 2050\. This creates the need for whole systems design of low-carbon renewable cooling and refrigeration solutions for public and commercial buildings.**The Solution:**Ventairge proposes a project titled **Lo**w-carbon **Re**newable **Co**oling & **R**efrigeration **S**ystem for Public and Commercial Buildings **(LoReCoRS).** LoReCoRS is focused on systematically developing and modelling a low-carbon renewable cooling and refrigeration solution. The project will comprise developing a high-fidelity model that will utilise solar technologies, storage modules, ancillary components and control systems in a systematic and holistic manner. Such a solution will support future integration into public and commercial buildings.**The key aspects of the system are:*** Delivers renewable energy for build cooling and refrigeration;* Utilises the sun as an energy source;* The system includes high storage energy density mediums;* Sophisticated control system for interaction and temperature balance.**The benefits offered by the system are:*** It supports the move towards carbon neutrality of public and commercial buildings;* It is energy efficient and can significantly reduce pollution;* It can achieve efficient interaction between heating and cooling;* The system can improve end users' experience, health, safety and well-being;* It can significantly reduce emissions and save energy bills.
