Simulation of an integrated hybrid desiccant vapor-compression cooling system
The performance of a desiccant, integrated, hybrid, vapor-compression cooling system is modeled numerically. The concept of hybrid cooling investigated in this paper utilizes the waste heat rejected from a vapor-compression cycle to activate a desiccant dehumidification cycle. The hybrid system consists of 4 major components: a compressor, an evaporator and 2 desiccant, integrated condensers/dehumidifiers. The equations governing the transport of heat and mass in the desiccant, integrated condenser/dehumidifiers are formulated considering air as the working fluid in the process stream and a refrigerant stream, which is cooled from superheated vapor to subcooled liquid, as the heat source during desorption; a water stream is used to remove the heat generated during adsorption. The governing equations are nondimensionalized and solved for both sorption processes using an explicit finite-difference scheme. The performance of a first generation prototype desiccant, integrated, hybrid, vapor-compression cooling system is then evaluated at ARI conditions.
