| Abstract: | With the development of energy efficient building, various alternatives for conventional heating, ventilating and air conditioning (HVAC) systems have emerging in recent two decades. Liquid desiccant dehumidification system has been widely studied because of its significant reduction in electricity consumption, enabling separately sensible and latent cooling to avoid the need for overcooling and removal of contaminants and disinfection of some airborne microbes from the air. Liquid desiccant dehumidification system has been considered as a promising application that can replace conventional vapor compression system, especially in hot and humid climate like Hong Kong, in which energy demand of dehumidification system is relatively high. This study aims to investigate the feasibility of applying liquid desiccant dehumidification in an air-conditioning system for the weather condition of Hong Kong by comparing the energy performance of the proposed system with the conventional vapor compression system. Annual primary energy consumption and operating cost of liquid desiccant dehumidification based air-conditioning system and variable-air-volume (VAV) system will be compared by simulation program EnergyPlus to verify whether the iquid desiccant dehumidification system is compatible for applying in Hong Kong. Furthermore, the influence of different heat sources of regeneration on energy consumption and operating cost of the proposed system will also be evaluated. |
