Global cooling demand continues to grow. To mitigate the resulting environmental impact, cooling solutions need to be sustainable. Adsorption chillers can provide sustainable cooling as they can employ both environmentally friendly driving forces such as solar or waste heat and the natural refrigerant water.

Water offers many advantages as refrigerant: its global warming potential is zero, it is absolutely safe, cheap, broadly available and has a high enthalpy of vaporisation. However, there are also challenges to employ water as refrigerant in cooling applications. On the one hand,...
