Modelling of cooled-ceiling air-conditioning systems: influences on indoor environment and energy consumption.

Author(s) : NIU J.

Type of monograph: Thesis

Summary

This thesis, presented for the degree of Doctor, discusses: 1) the critical review of turbulence computational fluid dynamics (CFD) techniques and their applications in building air flow studies; 2) development of a thermodynamic mathematical model and the enhancement of an existing computer code; 3) combined use of building dynamic simulation and computational fluid dynamics technique for the investigation of thermal comfort and ventilation effectiveness performance of three typical air-conditioning systems; 4) use of the dynamic model coupled with air-handling-unit and primary equipment models to simulate the annual energy consumption. Extract of contents: introduction; numerical simulation of indoor air flows; validation of turbulence models for natural convection flow in an enclosed room; dynamic simulation of building thermal processes; experimental validation of the enhanced cooling load program ACCURACY; thermal comfort and indoor contaminant distributions; annual energy analysis; concluding remarks and recommendations.
