“…At present, there are few studies on wind-heating at home and abroad, and some researchers have carried out theoretical analysis on the combined heat of wind and solar energy, but there is no any related experiment [6,7]. Agitating wind-heating device developed by Komatsu Manufacturing Co., Ltd., with a heating power of 25 kW, 30 L of water can be heated by a heater once to 15 to 20 °C [8].…”

In this work, a stirring and heating test system was built. An experiment at different rotational speeds within 1 h has been done for three working fluids: water, 46# hydraulic oil and saturated NaCl. Under the ideal state without considering the energy loss, the results show that the temperature rise of the working medium is faster as the rotation speed increases, the higher the heating efficiency. For example, the 46# hydraulic oil with smaller specific heat capacity is stirred at a speed of 500 r/min for 1 h, and the temperature is increased by 27.5 °C. In the same rotational speeds, the change of temperature and heating efficiency of different working fluids is complicated, and the physical parameters, such as the mass density, the specific heat capacity and the kinematic viscosity, have a great influence on the heating efficiency.

“…As a result, employing a mini-channel solar thermal panel could improve the amount of heat collection and reduce the cost of the system [9]. Notably, there are three desirable characteristics of northern Chinese rural houses for the utilization of solar energy systems: (1) a large flat roof area for the solar panels installation [10]; (2) rich solar resources throughout the year [11]; and (3) high residential density of large energy demand and low network energy loss. As a result, the potential to utilize solar energy systems in rural areas is larger than in urban buildings.…”

An efficient low-carbon system is proposed to meet the heating and cooling demands of rural houses in cold regions. Mini-channel solar panels incorporating a novel multiple-throughout-flowing loop are used for heat collection, whilst a vapour injection air source heat pump (VI-ASHP) is innovatively combined with an underfloor heating and cooling system. To demonstrate the system, a multiplethroughout-flowing mini-channel solar thermal panel array of 36 m 2 and a VI-ASHP of 40 kW heating capacity have been built and tested. Subsequently, mathematical models of the solar-assisted VI-ASHP system are established and compared with the experimental data. Based on the validated models, the energetic, economic and environmental performance is investigated under the typical weather conditions for a northern Chinese city (Taiyuan). The results indicate that, for a common rural house employing the proposed novel system, the proportion of the annual heat requirement, cooling load and hot water heating energy provided by solar thermal energy, photovoltaic energy and electricity from the power grid is 74.6%, 6.9%, and 18.5% respectively, thus giving a total energy supply proportion of 81.5% from solar energy. In addition, compared with a coal-powered system, our system has a cost payback period of 6.52 years and a life-cycle net cost saving of 56328.4RMB, thus the proposed system provides a greater economic performance. Furthermore, it can save 5tons of anthracite coal and reduce carbon emissions by 12.1tons annually. The proposed solar-assisted VI-

“…The energy consumption in rural areas is related to the activities of production, living standards, environmental quality and sustainable development. To exploit and utilize renewable energy, improve the source use technology, and to transform source consumption patterns not only have active effect on improving the efficiency of source utilization and reducing of environment pollution, but also have been an important way to resolve the problem of source shortage [1][2][3]. Optimizing the energy utilization structure and adjusting energy management policies have been an important aspect in advancing the rural areas development in many under-developed countries [4][5][6].…”

Household biogas is not only an important part of the development of rural new energy, but also an important aspect of sustainable development in China. This paper analyses the contributions and constraints of rural household biogas based on the sampling data in Gongzhuling County. The result shows that biogas construction can protect environment, improve the quality of famers' lives. However, the cold fermentation temperature and incomplete technological service mainly restrict the implement of biogas project. Basing on the analysis above, the paper brings forward the relevant countermeasures and policy suggestions.
