For solar heating systems, adding phase change material (PCM) can significantly increase the thermal storage capacity. This paper proposes a system using a PCM thermal storage unit cascadely combined with a water tank and configures a composite PCM suitable for the system. This study investigates the impact of this system configuration on the system efficiency while developing a matching principle...
Based on the analysis of bending damage of roadway roof, a design method of roof bolting support by using anchorage potential design method is put forward. The method is then applied to numerical simulation of roadway anchorage parameters and support effect. The effect of numerical simulation on supporting schemes was verified through laboratory tests, and the optimal support scheme for roadway was...
Balcony greening have the ecological effects on reducing temperature and increasing humidity,purifying air and beautifying environment etc. Combined the experiments with simulation, by figuring out the potency of reducing temperature and increasing humidity of balcony greening on indoor thermal environment, the correctness of the model was verified. The results show that the temperature of the greening...
