Sorption Heat Pump Systems

根据任务创新挑战7(建筑物的可负担得起的供暖和制冷)，这项研究的目的是研究和开发基于吸附技术的低成本热力热泵。关于吸附热泵的MI#7技术评估文件(TAD)专家报告确定了10个行动领域。该方案涉及三个方面：氨-盐再利用家用热泵、新型制冷循环、基于氨-盐再吸收的热交换器。然而，我们的重点是第一个领域。技术挑战涉及开发低成本的紧凑型反应器/热交换器(吸附反应器)，在该反应器中，氨制冷剂分别通过热输出或输入被化学盐快速吸附或解吸。我们的目标既是基本的：-了解/表征反应平衡和动力学、材料稳定性、腐蚀和b)应用：-使用开发的反应堆优化、设计、建造和实验室测试氨盐热泵。此外，这些输出将使我们能够调查这些新的加热和冷却技术如何在英国实施，确定可以实现哪些潜在的节省，实现这些技术所需的方法，并确定实施的潜在途径和政策影响。

The aim of the research, in accordance with Mission Innovation Challenge #7 (Affordable heating and cooling of buildings) is to investigate and develop low cost heat-powered heat pumps based on sorption technology. The MI #7 Technology Assessment Document (TAD) expert report on sorption heat pumps identified 10 Action Areas. This proposal addresses three of them: Ammonia-salt resorption domestic heat pump, Novel cycles for cooling, Heat transformer based on ammonia-salt resorption, however, our emphasis is on the first area.The technical challenges relate to development of low-cost compact reactor/heat exchangers (sorption reactors) in which ammonia refrigerant is rapidly adsorbed or desorbed by chemical salts with heat output or input respectively. Our objectives are both a) Fundamental:- understanding/characterising reaction equilibrium and kinetics, material stability, corrosion and b) Applied:- optimising, designing, constructing and laboratory testing of an ammonia-salt heat pump using the developed reactors.Additionally, these outputs will enable us to investigate how these new heating and cooling technologies can be implemented in the UK, identify what potential savings can be achieved, the approach required to deliver them and to identify potential routes to implementation and policy implications.
