直接蒸发式全新风机组在VRV新风系统中的应用

简述了直接蒸发式全新风机组的主要特点,并对该机组作为独立的新风系统在VRV系统中应用的优势进行了分析。同时指出在进行VRV新风系统设计时,需考虑到变新风工况下系统的空气处理过程,应注意室内综合热湿比、新风终状态和VRV系统室内机的热湿处理能力三者之间的关系,通过压缩机变容量技术,调整新风机组、VRV系统室内机内冷媒流量,来维持室内状态点的稳定。     

The Life of Space

The digital has revolutionised the notion of space that was formulated on the two-dimensional page in the Renaissance with the discovery of perspective and the printing press. Derrick de Kerckhove and Antonio Tursi explore how our ideas about space have been overturned since the onset of the computer and the many different ways that architects are reinterpreting them.

The New Delfina

Peter Cook eulogises the exuberant: he urges us to recognise its potential for release, as a true opportunity to let go creatively – and, in fact, to let it all ‘rush out in a torrent’. In tandem, he redraws the Sheraton Delfina in Santa Monica from his hotel window, as an exuberant pile or liveable conglomeration of grotto-like spaces. Copyright © 2010 John Wiley & Sons, Ltd.

Fecal coliform disappearance in a river impoundment

Fecal coliform (FC) disappearance studies were conducted in Ford Lake during the summer of 1979. Ford Lake, an artificial impoundment at the lower end of the Huron River drainage basin below Ypsilanti, Michigan, receives all upstream flow (2072 km² of drainage). During dry weather an overall daytime FC disappearance rate of 0.4 (h⁻¹) (K base e) was measured using dye tracer for timed collection. assuming a first order equation of the Chick type. Sedimentation was demonstrated as important in the overall FC disappearance in the upper end of the lake. Rooftop studies showed light level to affect daytime disappearance. Two types of wet weather conditions were documented: (1) where a substantial increase in flow occurred due to an isolated upriver storm; and (2) as a result of two different storm events in the Ford Lake area itself. In both cases, Ford Lake was effective in substantially reducing the large FC contribution.
