solar Heating and cooling present and future development
Renewable Energy, 2017Co-Authors: T S Ge, R Z Wang, Z Y Xu, S Du, X M Chen, X N Wu, Jinge ChenAbstract:Abstract Using conventional fossil fuels causes both energy crisis and environmental pollution. Renewable energy with the merits of almost unlimited availability and environmental-friendliness provides a perfect solution to the problem. Solar energy is widely recognized as one of the most important renewable energy resources due to its even distribution, safety and serving as sources for others. In past decades, global solar thermal capacity increases rapidly and now it has been widely used worldwide to provide Heating and cooling. To understand the current progress of relevant technologies and the future development, this paper briefly summarizes the current situation of solar Heating and cooling, and then some new achievements in related areas and potential future market penetration are discussed. It is found that solar hot water Heating System's development is in fast lane in recent years with evacuated tube solar collector dominating the mass market. How to integrate solar collecting System with different types of Buildings is the main research and development direction for solar Building Heating System. Large-scale district water Heating System and solar PVT System as the most promising solutions attract extensive attentions. For solar cooling, efforts have been made to improve the efficiency of conventional solar thermal cooling methods in terms of adsorption and absorption technology. In addition to technical development, economic analysis of solar Heating and cooling System is also discussed. Return of investment period is widely adopted to evaluate the economic performance. Results reveal that low initial cost and advantageous allowance are the most efficient ways to make solar Heating and cooling System economically attractive. This paper is presented and recommended by 5th International Conference on Nuclear and Renewable Energy Resources.

Energy and exergy analysis of fossil plant and heat pump Building Heating System at two different dead-state temperatures
Energy, 2010Co-Authors: S.p. LohaniAbstract:In this paper, we deal with the energy and exergy analysis of a fossil plant and ground and air source heat pump Building Heating System at two different dead-state temperatures. A zone model of a Building with natural ventilation is considered and heat is being supplied by condensing boiler. The same zone model is applied for heat pump Building Heating System. Since energy and exergy demand are key parameters to see which System is efficient at what reference temperature, we did a study on the influence of energy and exergy efficiencies. In this regard, a commercial software package IDA-ICE program is used for calculation of fossil plant Heating System, however, there is no inbuilt simulation model for heat pumps in IDA-ICE, different COP (coefficient of performance) curves of the earlier studies of heat pumps are taken into account for the evaluation of the heat pump input and output energy. The outcome of the energy and exergy flow analysis at two different dead-state temperatures revealed that the ground source heat pumps with ambient reference have better performance against all ground reference Systems as well as fossil plant (conventional System) and air source heat pumps with ambient reference.

performance and economic evaluation of evacuated tube solar collector with auxiliary electric heater for rural Heating
Energy Procedia, 2019Co-Authors: Lai Yanhua, Hao Wengang, Yu Hongwen, Zheng Jian, Lyu MingxinAbstract:Abstract The evacuated tube solar collector with auxiliary electric heater (ETCAEH) was presented for rural Heating in this study. The examined Building Heating System with evacuated tube solar collector was designed and constructed in Jinan city, china. The aim of this study is to analyze the feasibility of Building Heating System presented. Thermal performance and economic analysis of ETCAEH for rural Heating were investigated. The results show that the Heating room indoor air temperature can meet Heating demand by adopting ETCAEH. Furthermore, ETCAEH used in rural area has applicative enough for their advantages in economy by comparing with coal-fired boiler and air conditioning. It is said that this study will provide guidance for designing and economic feasibility of ETCAEH used in Building Heating.

Analysis of different heat pumping technologies integrating small scale solid oxide fuel cell System for more efficient Building Heating Systems
International Journal of Hydrogen Energy, 2015Co-Authors: Andrea Frazzica, Antonio Sapienza, N Briguglio, Vincenza Antonucci, Angelo Freni, G. Brunaccini, Marco FerraroAbstract:Development of advanced Heating Systems, able to reduce the energy consumption of Buildings is still an open issue. Different technologies, either already at commercial level or in a pre-commercial phase, are available. Among them, heat pumps and fuel cells represent good options, thanks to their high efficiency and flexibility of operation. The present paper analyses one of the possible ways to integrate a heat pump with a micro-Combined Heat and Power (CHP) based on Solid Oxide Fuel Cell (SOFC) technology, in order to increase the overall efficiency of the Building Heating System. Three different heat pumping technologies (namely vapour compression, absorption and adsorption) have been employed. Starting from performance data of commercial appliances (vapour compression and absorption heat pumps) and from performance experimentally measured at the CNR ITAE for appliances at prototyping level (adsorption heat pump and SOFC), a numerical model has been developed in TRNSYS. Simulations performed demonstrated that the overall yearly efficiency can be improved up to 30%, exploiting the heat released by the micro CHP to reduce the heat produced by the heat pump.
