In China, a large amount of the total energy consumption is made up of building energy, particularly in humid regions. The conventional vapor compression refrigeration systems cannot effectively control the indoor humid and thermal environment. Therefore, this article proposes a solar-powered desiccant wheel and ground-source heat pump (SDW-GSHP) air conditioning system. The energy consumption of the system is mainly from sustainable sources of solar and geothermal energy, showcasing excellent energy efficiency and environmental friendliness. The desiccant wheel (DW) processes latent heat loads, and the GSHP processes the sensible heat load. The regeneration air of the DW is heated by a solar collector. The operational performance of the system was simulated by using TRNSYS during the typical summer week (15 July to 22 July) in Qingdao. The simulation results indicated that indoor temperature was maintained within 25.8–26.2 °C and the relative humidity was maintained in the range of 57–61%. The COP of the SDW-GSHP air conditioning system was 42.1% higher than that of the DW air conditioning system with electric heating regeneration, and electricity saved 43.7%.

“…Air conditioners mainly operate on Vapour Compression Refrigeration System (VCRS), which consumes a large amount of electrical energy. Solar cooling is a significant solution to global warming and environmental degradation [56][57][58][59][60]. The major option to the conventional VCRS is solar used Liquid Desiccant (LD) dehumidification followed by evaporative water cooling.…”

In the past decades, desiccant cooling systems have received much attention. These systems are considered as an alternative way to decrease energy consumption and greenhouse gas emission in humid and hot locations. To address the importance of desiccant air-conditioning systems, the present research aims to provide an overview of recent studies on the development of desiccant air conditioning system. Another objective is to consider the numerical and theoretical analysis of desiccant systems. Moreover, for the first time, a summary of recent researches regarding the use of Computational Fluid Dynamics (CFD) technique for numerical modeling of desiccant cooling systems has been especially reviewed in detail. Finally, in the present review, the principle of regeneration of liquid desiccant using solar energy have also been considered briefly.

“…Wang et al [30] used a simulation method including a parametric and optimization study on a novel transient air dehumidifier to meet a constant energy supply with multi-stage desiccant plates. Rayegan et al [31] also proposed an optimization based upon a dynamic simulation for a solar-assisted desiccant cooling system but it was also integrated with a ground source heat exchange. The results have suggested that the system can not provide thermal comfort in extremely humid regions with high regeneration temperatures and the integration with ground source heat exchange can significantly decrease the regeneration temperature.…”
