从舒适性角度谈卧式风机盘管的选择

卧式风机盘管作为舒适性空调系统中大量使用的一种末端设备，在设备选择时，不能忽视设备的舒适特性。通过对三种卧式风机盘管的舒适性的比较，发现同一规格的产品，其在房间内的冷气流的运动轨迹、温度、速度衰减有较大的不同，因而对房间的舒适性有较大的影响，从舒适性角度考虑应选择风量大，送风温差小的设备；指出开发低焓差的产品，从而对提高设备的舒适特性很有必要。

Effects of Eubacterium coprostanoligenes and Lactobacillus on pH, Lipid Content, and Cholesterol of Fermented Pork and Mutton Sausage-Type Mixes

Pork and mutton sausage-type mixes produced using Eubacterium coprostanoligenes with or without Lactobacillus as starter culture showed changes in pH, cholesterol and lipid content. Viability of E. coprostanoligenes was assessed by culturing samples from each treatment and analyzing for coprostanol, a cholesterol metabolite. The pH and/or cholesterol decreased (P < 0.05) in the sausage-type mixes inoculated with E. coprostanoligenes or Lactobacillus or their combinations. Variability in lipid content was observed among and within treatments. Very low (6.2 μg/g dry matter) concentrations of coprostanol were produced in sausage-mixes and cultures except when inoculated with 2.0 g of E. coprostanoligenes (from 8.2 to 130.6 μg/g dry matter).

鲜食玉米加工工艺及自动化设备设计

目的：解决鲜食玉米切割时准确率较低，随机误差较大，容易损伤籽粒问题。方法：设计了一种新型工艺的甜糯玉米加工生产线，该生产线利用机器视觉技术对玉米姿态进行判断，通过换向设备完成玉米姿态调整，设计适应性定位机构分别对玉米头尾进行切割，再依据切割后果穗苞叶附着力差异特点进行留层加工，经相机品质筛选后装箱，并利用样机进行加工试验。结果：该生产线加工效率达1 500穗/h；留层合格率为90.2％；籽粒破损率为1.81％。结论：该鲜食玉米加工生产线实现了玉米的上料、排序、切割、剥皮等工序自动化，实现苞叶合理留层，对比传统设备更加保护玉米籽粒。     

A fault-tolerant and energy efficient control strategy for primary-secondary chilled water systems in buildings

Primary-secondary chilled water systems with decoupled bypass in building air-conditioning often cannot work in healthy condition as desired in practical operation, due to excess secondary flow demand resulting in deficit flow in the bypass line. This paper presents a fault-tolerant and energy efficient control strategy for secondary chilled water pump systems to solve this operation and control problem providing enhanced operation performance and energy efficiency of chilled water systems. The strategy employs the flow-limiting technique that ensures the water flow of secondary loop not exceed that of the primary loop while still maintaining highest possible delivery capacity of cooling to terminals. The strategy is also integrated with a differential pressure set-point optimizer to determine the optimal set-point. The performance of this strategy is evaluated in a simulated real-life environment representing the chilled water system in a super high-rise building by comparing it with two conventional control strategies. Results show that the proposed strategy can effectively eliminate the deficit flow at both starting and normal operation periods. The energy saving in the secondary chilled water pumps can be up to over 70% and 50% at system starting and normal operation periods respectively compared with the other strategies.     

Quality and antioxidant capacity of fresh‐cut apple wedges enriched with honey by vacuum impregnation

The effect of vacuum impregnation (VI) of fresh‐cut apple wedges with honey, in presence and absence of a browning inhibitor on physicochemical, sensory and antioxidant properties over 7 days of storage at 2–4 °C was studied. Infusion of wedges with honey resulted in very little weight change indicating loss of internal water and ingress of honey carbohydrates into the wedges, hence the correlation coefficients with soluble solids content (r = ?0.91) and dry matter (r = ?0.77). Water infused samples showed the highest water uptake resulting in an increase in weight of 30%. Browning (P < 0.001) and firmness (P < 0.001) of apple wedges were the quality parameters most affected by VI. Samples dipped in browning inhibitor prior AS1 showed slightly better performance than undipped wedges with regard to browning and firmness. Total phenol content and antioxidant activity were significantly (P < 0.001) lower for honey infused apple wedges.

Chilled ceilings and displacement ventilation

Displacement ventilation and chilled ceiling systems have been promoted as being ‘greener’ alternatives to other common forms of air conditioning system. They have been viewed by some of the building services industry as a welcome departure from the traditional ‘North American’ systems of air conditioning most frequently adopted to date, and could be viewed as a more suitable alternative for use in the moderate climatic conditions of the UK.This paper reviews some of the authors' recent and current work on the performance of these systems in office environments.
