A highly energy efficient compression adsorption hybrid for modern HVAC

In hot and humid climate like Singapore, a renewable energy-based cooling displacement ventilation system offers an attractive solution, where either a heat-driven sorption chiller or an electrically driven vapor compression chiller or their hybrid could be used as a partner system for the air condi...
