When the surface temperature of the outdoor coil in an air source heat pump (ASHP) unit is lower than both freezing point of water and the air dew point, frost can be formed and accumulated over outdoor coil surface. Frosting affects the energy efficiency, and periodic defrosting therefore is...

An artificial neural network (ANN)-based dynamic model for an experimental variable speed direct expansion (DX) air conditioning (A/C) system has been developed, linking the indoor air temperature and humidity controlled by the DX A/C system with the variations of compressor and supply fan...

China’s energy needs and its environment are facing great challenges because of the country’s rapid urbanization and industrialization. It is China’s strategic choice to exploit renewable energy to guarantee its energy security and reduce CO2 emissions. Crop residue has been identified and...

Driven by the desire to reduce environmental impacts and achieve energy independence, electric vehicles (EVs) are poised to receive mass acceptance from the general public. However, simultaneously connecting to electric distribution grid and charging with large number of EVs bring the necessity...

This study assesses the future impacts of biofuel production from the world’s major biofuel producers (the US, Brazil and the EU) over the next decade on global markets and the resulting spatial implications on income distribution and agricultural production in China. Rising global commodity...

China is now the third largest bioethanol producer in the world after the United State and Brazil. The overall goals of this paper are to provide an overview of China's current bioethanol program, its future trend, and the likely impacts on its agricultural economy in the future. The analysis...

Similar to many other countries, all nations in the Greater Mekong Subregion (GMS) have planned or are planning to develop strong national biofuel programs. The overall goal of this paper is to better understand the impacts of global and regional biofuels on agriculture and the rest of the...

This research uses GTAP model to assess the expected future effects of national and global biofuels policies on agriculture markets and food prices in Pakistan. Our results show that by 2020, global mandates on biofuels will significantly affect the prices, production and trade of major...

In this paper, polystyrene(PS)/n-dotriacontane(Dot) composite nanoencapsulated phase change material (NEPCM) for thermal energy storage was synthesized by a facile and time-saving ultrasonically initiated miniemulsion polymerization method. The influences of ultrasonic factors including...
