Component modeling and system simulation of a hybrid heat driven cooling and dehumidification system.

摘要

Mathematical models for cooling coils, packed and coil type liquid desiccant absorbers, and counter and crossflow cooling towers used in conventional and non-conventional air-conditioning systems are developed and/or identified from existing literature. For the simulation of an air-conditioning system, the mathematical models can be classified as detailed or simplified models. The performance predictions of the detailed and simplified models of the components mentioned above are compared extensively with the performance data reported in commercially available catalogs to verify their accuracy. In general a good agreement is found between the performance predictions of a detailed model, a simple model, and the performance data reported in the catalogs for each component. Based on the components models, three different types of air-conditioning system were simulated for application in Puerto Rico. The results from these simulations revealed that for liquid desiccant systems a large fraction of the cooling requirements could be easily fulfilled by using a cooling tower. Also, a large fraction of the heating source requirements could be fulfilled by a renewable energy source such as solar energy.
