Yunnan is one of the less developed provinces in China, but has abundant energy resources, and is an ideal destination for tourists around the world due to its perfect climate and unique sightseeing resorts. However, energy consumption in rural households relies mainly on straw (12.15%),...

The preserved greengage is a favorite dried fruit in China. In processing preserved greengages, the drying of salted greengages is a key and energy-consuming process. Traditionally, the drying of salted greengages mainly relies on natural sun drying and requires about 48 days. In this study, an...

With the rapid development of the Chinese economy, energy consumption has increased considerably, and this has increased pressure on energy production. On the other hand, this pressure has greatly assisted in the development of the renewable energy in the past two decades. This paper reports the...

In this work, the optical performance of solar panels with a new sun-tracking technique was theoretically investigated based on the proposed mathematical method and monthly horizontal radiation. The mechanism of the investigated sun-tracking is that the attitude angle of solar panels is daily...

To investigate the optical performance of the vertical single-axis (v-axis, in short) tracked solar panels as compared with fixed and full 2-axis tracked solar panels, a mathematical procedure to estimate the annual collectible radiation on fixed and tracked panels is suggested based on the...

To investigate optical performance of the inclined south-north single-axis (ISN-axis, in short) tracked solar panels, a mathematical procedure to estimate the annual collectible radiation on fixed and tracked panels was suggested based on solar geometry and monthly horizontal radiation. For...

A roof pond with gunny bags floating on water surface (RPWGB) has been proven to be an efficient evaporative based cooling technique in the previous studies of the authors due to the creation of thermal stratification inside the pond. In this paper, a mathematical model is developed for the...
