The optimal design and operation of a liquid desiccant dehumidifier needs the understanding of the flow mechanism. However, the study in this aspect is still limited. In the present work, a model has been established on the basis of computational fluent dynamics (CFD) software. With the model,...

This paper discusses the potential for electricity generation on Hong Kong islands through an analysis of the local weather data and typical wind turbine characteristics. An optimum wind speed, uop, is proposed to choose an optimal type of wind turbine for different weather conditions. A...

The paper aims to overview various mathematical models for modeling the simultaneous heat and mass transfer process in the liquid desiccant dehumidifier. Firstly, the dehumidification principle is introduced briefly. Then the models are interpreted in terms of two classes of dehumidifiers. For...

Climate change and energy security are forcing Hong Kong to shift from a fossil fuel-based to a clean and low-carbon energy structure. In this article, a simulation model for Hong Kong's energy system is developed to examine the present energy structure and analyse alternative future sustainable...

Optimal WT (wind turbine) layout patterns relate in detail to the specific conditions of OWF (offshore wind farm) environments and therefore each is different. This paper presents an investigation into optimal WT layout patterns for three OWF configurations (aligned, staggered, scattered) in HK...

Standalone renewable energy (RE) systems hold the most promising solution to the electrification of remote areas without utility grid access, while a feasible energy storage is a core part for achieving a continuous and reliable power supply since RE is usually intermittent and weather...

This paper studied the thermal and power performances of a ventilated photovoltaic façade under different ventilation modes, and appropriate operation strategies for different weather conditions were proposed accordingly to maximize its energy conversion efficiency. This ventilated PV...

A simulation model for modeling photovoltaic (PV) system power generation and performance prediction is described in this paper. First, a comprehensive literature review of simulation models for PV devices and determination methods was conducted. The well-known five-parameter model was selected...
