A modified zone model for estimating equivalent room thermal capacity

Hua CHEN, Xiaolin WANG

Frontiers in Energy 2013, Volume 7, Issue 3, Pages 351-357 doi: 10.1007/s11708-013-0254-x

Abstract: The zone model has been widely applied in control analysis of heating, ventilation and air conditioning (HVAC) systems to achieve a high building efficiency. This paper proposed a modified zone model which is much simpler in the HVAC system simulation and has the similar accuracy to the complicated simulation model. The proposed model took into consideration the effect of envelop heat reservoir on the room indoor temperature by introducing the thermal admittance of the inner surfaces of the building enclosure. The thermal admittance for the building enclosure was developed based on the building thermal network analytical theory and transfer function method. The efficacy of the proposed model was demonstrated by comparing it with the complicated model — heat balance method (HTB2 program). The predicted results from the proposed model well agreed with those from the complicated simulation. The proposed model can then make the HVAC system dynamic simulation much faster and more acceptable for control design due to its simplicity and efficiency.

Equivalent linearization method based on assessment area in the analysis-design of pressure vessels

Yin Yihui,Yu Shaorong

Strategic Study of CAE 2008, Volume 10, Issue 10, Pages 31-35

Abstract:

Based on the analytical solutions of a spherical pressure vessel subjected to internal pressure, it points out that the results of membrane stress and bending stress are inaccurate obtained by the one-dimension integral along a line called assessment line in the direction of shell thickness recommended by some references and standards. Therefore, a more accurate method is presented in which the resorted stresses are obtained through two-dimension integral over a ring cross-section area called assessment area of the shell. As an example, an analysis based on the elastic analytical solutions of a thick-walled spherical shell bearing internal pressure shows that the method suggested by this paper can make analysis and design of pressure vessels more accurate.

Allocation of grassland, livestock and arable based on the spatial and temporal analysis for food demand in China

Huilong LIN, Ruichao LI, Yifan LIU, Jingrong ZHANG, Jizhou REN

Frontiers of Agricultural Science and Engineering 2017, Volume 4, Issue 1, Pages 69-80 doi: 10.15302/J-FASE-2017140

Abstract: To explore the distribution of food demand and the projected trend in future food demand in China, this paper analyzed the change in current (1998–2012) per-capita demand for grain, grain-consuming and herbivorous livestock products, and predicted the food demand in 2020. The results indicated that in 1998–2012, the national per-capita consumption of grain ration declined by about 36.66%, and the per-capita consumption of grain-consu-ming and herbivorous livestock products increased by about 48% and 34.09%, respectively. The grain-consu-ming livestock products have become the primary source of both calories and protein for consumers. The proportion of herbivorous livestock products in consumer diets has increased steadily and there has been huge potential in substituting beef and mutton for pork in this dynamic market. The demand for food in different provinces of China is highly variable, which is important for planning grassland agriculture development and ensuring food safety. The demand for grain, and grain-consuming and herbivorous livestock products will increase by about 3.3%, 20% and 14% respectively by 2020. Based on the food demand and trend in the development of grassland agriculture, the 31 provinces in China are divided into three priority groups for grassland agriculture development.
