China’s new problems of food security revealed by the Food Equivalent Unit

Huilong LIN,Ruichao LI,Cangyu JIN,Chong WANG,Maohong WEI,Jizhou REN

Frontiers of Agricultural Science and Engineering 2014, Volume 1, Issue 1, Pages 69-76 doi: 10.15302/J-FASE-2014023

Abstract: China's food security has a great influence on the world, and has always been the top priority in Chinaof food diversity is increasing, research based on nutrition security and broad food systems are increasinglyThus, not only grain for human consumption, but also animal foods have been integrated into the FoodEquivalent, which is used to analyze China’s current agriculture system and reveal the water resourceSo there exist an obvious disparity in animal food supply between China and these two countries.

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.
