simulation of a solar absorption Air Conditioning system
Energy Conversion and Management, 2001Co-Authors: K SumathyAbstract:This paper presents the simulation of a solar-powered absorption Air Conditioning system with the absorption pAir of lithium bromide and water. An attempt is made to increase the COP of the system by partitioning a single storage tank into two parts. In the morning when sunshine is low, the upper part is activated, and in the afternoon, the whole (upper and lower) tank is connected to the collector. The analysis indicates that it is preferable to utilize a partitioned water tank rather than the normal stratified water tank because the cooling effect can be realized much earlier compared to the normal stratified water storage tank. Also, the overall cooling efficiency (cooling load to total solar energy ratio) was found to be higher for the partitioned storage Air Conditioning system.

technology development in the solar absorption Air Conditioning systems
Renewable & Sustainable Energy Reviews, 2000Co-Authors: K SumathyAbstract:Abstract An environmental control system utilizing solar energy would generally be more cost-effective if it were used to provide both heating and cooling requirements in the building it serves. Various solar powered heating systems have been tested extensively, but solar powered Air-conditioners have received little more than short-term demonstration attention. This paper reviews past efforts in the field of solar powered Air-Conditioning systems with the absorption pAir of lithium bromide and water. A number of attempts have been made by researchers to improve the performance of the solar applied Air-Conditioning (chiller) subsystems. It is seen that the generator inlet temperature of the chiller is the most important parameter in the design and fabrication of a solar powered Air-Conditioning system. While collector choice, system design and arrangement are other impacting factors for the system operation.

numerical and experimental investigation on solid desiccant assisted mobile Air Conditioning system
2017Co-Authors: Hoseong Lee, Yunho HwangAbstract:In the conventional mobile Air-Conditioning system, evaporating temperature should be lower than the dew point temperature of cabin to control the temperature and humidity. Thus, reheating of the Air is necessary. These two factors could increase the fuel consumption of the system. To overcome these issues, a solid desiccant-assisted mobile Air-Conditioning system is proposed and investigated. It is proposed to apply the solid desiccant to the mobile Air-Conditioning system to handle most of latent load, while the vapor compression cycle (VCC) handles the remaining latent load and sensible load. The model of the proposed concept is developed and validated with experimental data. Then, the possible configurations of the solid desiccant-assisted mobile Air-Conditioning system are discussed. Lastly, the proposed system is experimentally investigated with various operating conditions.

performance investigation on solid desiccant assisted mobile Air Conditioning system
Applied Thermal Engineering, 2016Co-Authors: Yunho Hwang, Hoseong Lee, Xiaojie Lin, Reinhard RadermacherAbstract:Abstract In the conventional mobile Air Conditioning system, the temperature and humidity control is achieved by a vapor compression system. This system cools the Air down to lower than the dew point temperate of the cabin to control the humidity. Thus, reheating of the Air is necessary. These two factors could increase the fuel consumption of the system. To overcome these issues, a solid desiccant assisted mobile Air Conditioning system is proposed and investigated. The desiccant assisted technology can separate the latent heat load from the sensible heat load, which will effectively increase the evaporating temperature and reduce the power consumption of the compressor. It is proposed to apply the solid desiccant to the mobile Air Conditioning system to handle most of latent load, while the vapor compression cycle handles the remaining latent load and sensible load. The model of the proposed concept is developed and validated with experimental data. Lastly, the possible configurations of the solid desiccant assisted mobile Air Conditioning system are discussed.

application of geothermal absorption Air Conditioning system a case study
Applied Thermal Engineering, 2013Co-Authors: Alex Bierwirth, Alexander Christ, Peter B Whittaker, Klaus Regenauerlieb, Hui Tong Chua, Xiaolin WangAbstract:Possible applications of geothermal energy are increasingly attracting worldwide interest as a low carbon source of energy. Sedimentary basins offer an accessible low grade geothermal heat source to launch energetically efficient Air-Conditioning systems. The natural temperature, porosity and permeability of these sedimentary basins may be sufficient to provide usable geothermal power for heat-driven sorption Air-Conditioning system. In the Perth metropolitan region, hot sedimentary aquifers with temperatures between 70 and 100 °C are generally available at around 3 km depth or shallower. This paper outlines the possible application of a large scale geothermal absorption Air-Conditioning system to provide baseload cooling to the main campus of the University of Western Australia (UWA). The conceptual design of this system is proposed. The design considerations and the performance outcomes are presented. The economic analysis based on the real-time cooling load profile at the UWA and the chiller operation scheme demonstrates the viablity of geothermal absorption Air-Conditioning system. This paper will help engineers appreciate the opportunities and barriers to geothermal applications, the latest developments and how this technology may help to significantly reduce carbon dioxide emissions.

progress in heat pump Air Conditioning systems for electric vehicles a review
Energies, 2016Co-Authors: Qinghong PengAbstract:Electric vehicles have become increasingly popular in recent years due to our limited natural resources. As a result, interest in climate control systems for electric vehicles is rising rapidly. According to a variety of research sources, the heat pump Air Conditioning system seems to be a potential climate control system for electric vehicles. In this paper, an extensive literature review has been performed on the progress in heat pump Air Conditioning systems for electric vehicles. First, a review of applications of alternative environmentally friendly refrigerants in electric vehicles is introduced. This is followed by a review of other advanced technologies, such as the inverter technology, innovative components and the system structure of the heat pump Air Conditioning system for electric vehicles. Lastly, recent developments in multiple source heat pump systems are presented. The use of these advanced technologies can provide not only sufficient refrigerating capacity for the electric vehicle, but also higher climate control system efficiency. We believe that ideal practical Air Conditioning for electric vehicles can be attained in the near future as the mentioned technical problems are gradually resolved.
