7. Conclusion
Hermetically sealed solid sorption thermal systems, using water as a refrigerant, have long been considered solutions for natural gas air-conditioning, particularly in the context of trigeneration. First with zeolite 13X, then with silica gels and SAPO-34. But with decarbonization, natural gas air conditioning is no longer an objective.
Air-conditioning using waste heat, or even solar energy, is now the preferred choice. In this new dynamic, designers are turning to new systems. Silica gel-water or SAPO-34-water couples are currently the most widely used. These manufacturers have made efforts to offer products that can operate at low hot-source temperatures (up to 50°C) but with low thermal discharge temperatures (below 35°C). These products are well suited to temperate climates.
The emergence of MOF-water couples could change the situation...
