A small-scale pilot project was built for the pavement-solar energy utilization in this paper. An automatic data acquisition system was designed to measure the effectiveness of the pavement solar energy system based on the operation data of 24h a day in both summer and winter. Through 69days...

Hydrothermal liquefaction (HTL) of barley straw with K2CO3 at different temperatures (280–400°C) was conducted and compared to optimize its process conditions; the aqueous phase as a co-product from this process was recycled to explore the feasibility of implementing wastewater reuse for...

Micro-algae have been recognized as a promising feedstock for biofuel production. Effective combining microalgae cultivation with wastewater treatment can reduce CO2 emissions and the cost of microalgae biofuel production, making it more feasible. However, the biomass and lipid productivity must...

To evaluate the effect of phase change materials (PCMs) on the indoor thermal environment of greenhouses under different weather conditions and over a long time in the heating season, a study was carried out using both experimental method and numerical method. The study was conducted in a...

In this paper, we report on an underground water-source water-loop heat-pump (UWSWLHP) air-conditioning system for a tall apartment building in Beijing. Water at 14 °C was used as an external low-temperature heat-source. By analyzing field-test data for two years, the authors assessed the...
