A modified model for a borehole ground heat exchanger borefield (BHE) of a ground-source heat pump (GSHP) system was developed based on a three-dimensional finite difference scheme which could cater for multiple ground layers and an inhomogeneous groundwater flow in the soil. The model was...

A simplified three-dimensional finite difference model for a single (cylindrical energy pile) CEP was developed. The present model was first verified with an analytical solution based on the special case that the material inside and outside the CEP had the same thermal properties. For the case...

This study is to advance the energy performance of solar air-conditioning system through appropriate component integration from the absorption refrigeration cycle and proper high-temperature cooling. In the previous studies, the solar absorption air-conditioning using the working pair of water...

The solar–thermal refrigeration systems, covering the solar absorption refrigeration system (SAbRS) and the solar adsorption refrigeration system (SAdRS), were designed for typical office in the subtropical Hong Kong. The approach of simulation–optimization was adopted in order to determine...

Trigeneration, which is able to provide cooling, heating and power, has been advocated to be a sustainable solution for building use in the urban area. With the high-temperature feature and maintenance convenience, solid oxide fuel cell (SOFC) becomes a promising prime mover of trigeneration. In...
