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

** 挑战与机遇：** 建筑物的排放量估计高达英国总排放量的30%（BEIS，2021）。英国的季节性制冷需求是由办公室和零售店的制冷需求驱动的，最近的夏季热浪是一个驱动因素。除了空间冷却，空调还用于超级计算机和冷藏食品的通风。在制冷方面，英国超市消耗的能源中有70%用于制冷（EGB，2021年）。公共和商业建筑（如医院和零售店）对冷却和制冷的需求使得减少此类建筑物的排放非常具有挑战性，因为自1990年以来，由于排放情况没有变化，因此缺乏整体系统方法（BEIS，2021）。减少公共和商业建筑因冷却和制冷而产生的排放需要采用整体系统方法来应对挑战，到2050年实现净零排放。这就需要为公共和商业建筑提供低碳可再生冷却和制冷解决方案的整体系统设计。**解决方案：**Ventairge提出了一个名为 **Lo**w-carbon **Re**newable **Co**oling & **R**efrigeration **S** 的项目，用于公共和商业建筑 **（LoReCoRS）。** LoReCoRS专注于系统开发和建模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。这种解决方案将支持未来集成到公共和商业建筑中。**该系统的关键方面是：* 为建筑冷却和制冷提供可再生能源;* 利用太阳作为能源;* 该系统包括高储能密度介质;* 复杂的控制系统，用于交互和温度平衡。该系统提供的好处是：* 它支持公共和商业建筑迈向碳中和;* 它是节能的，可以显着减少污染;* 它可以实现加热和冷却之间的有效互动;* 该系统可以改善最终用户的体验，健康，安全和福祉;* 它可以显着减少排放并节省能源费用。

**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.
