On the performances of a hybrid air-conditioning system in different climatic conditions

Publication year: 2011brbSource:/b Energy, In Press, Corrected Proof, Available online 23 July 2011brStefano, Bergero , Anna, ChiaribrIn previous papers the authors demonstrated that significant energy savings can be achieved in air-conditioning through the use of a hybrid plant in which a vapor-compression inverse cycle is integrated with an air dehumidification system working with hygroscopic solution and hydrophobic membrane. The advantage of this system lies in the fact that the refrigeration device operates at a higher evaporation temperature than that of a traditional system, in which dehumidification is achieved through condensation.In the proposed hybrid system the supplied air is simultaneously cooled and dehumidified in an air–solution membrane contactor. The LiCl solution is cooled by means of a…br Highlights: ► A hybrid air-conditioning plant is simulated in summer climatic conditions. ► A vapor-compression inverse cycle is integrated with an air dehumidification system working with liquid desiccant and hydrophobic membrane. ► The performances of the hybrid system are compared with those of a direct-expansion air-conditioning plant. ► The energy saving may exceed 60% when the vapor load in the conditioned environment is high.
