Experimental Performance Analysis And Evaluation Of A Novel Frost-Free Air Source Heat Pump System, Zhihua Wang, Fenghao Wang, Zhenjun Ma, Mengjie Song, Wenke Fan

To tackle the problem of frosting occurred on the outdoor coil surface when an air source heat pump (ASHP) is operated in winter, a novel frost-free ASHP system has been developed. However, the dehumidification performance and the frost-free time of the system operated are highly dependent on the electronic expansion valve (EEV) opening of the 1st stage throttle. In addition, the coefficient of performance (COP) of the systems is controlled by the EEV opening of the 2nd stage throttle. Therefore, the objective of this study is to investigate the effect of the EEV opening on the system thermodynamic performance in …

Modulated electro-hyperthermia (mEHT) is a form of hyperthermia used in the treatment of cancer. It is a variation that relies on a particular form of enhanced selectivity to enable more effective cancerous cell death yet maintaining the integrity of healthy non-cancerous cells. It is yet to successfully make the major step into the wider medical community despite several encouraging trials. In this study, we investigate mEHT from an in vitro perspective. We demonstrate a supra-additive effect on 9 L gliosarcoma cells when exposed to mEHT in combination with MV X-ray radiation. The supra-additive effect is hypothesized to be induced by …

A stone column typically consists of particles whose influence has largely been overlooked in design practice in terms of stress transfer, pattern of deformation, and intrusion of fines (clogging). This article presents an experimental study on the load-deformation behavior of a model stone column installed in soft clay with a particular emphasis on the influence of particle gradation and shape under undrained loading. The results show that particle gradation and shape have a significant influence on the load-deformation behavior and the extent of fines intrusion into the stone columns. Relatively well-graded particle sizes favor the development of higher peak shear …

Hot rolling tests of a low-alloy steel were conducted at a rolling temperature of 850 °C under different lubrication conditions, including benchmarks (dry condition and water) and water-based nanolubricants containing different concentrations of nano-TiO2 from 1.0 to 8.0 wt%. The effects of nanolubricants on rolling force, surface roughness, thickness of oxide scale, and microstructure were systematically investigated through varying nano-TiO2 concentrations. The results show that the application of nanolubricants can decrease the rolling force, surface roughness and oxide scale thickness of rolled steels, and refine ferrite grains. In particular, the nanolubricant containing an optimal concentration (4.0 wt%) of …

Model predictive control has proved to be a promising control strategy for improving the operational performance of multi-source thermal energy generation systems with the aim of maximising the exploitation of on-site renewable resources. This paper presents the formulation and implementation of a model predictive control strategy for the management of a latent heat thermal energy storage unit coupled with a solar thermal collector and a backup electric heater. The system uses an innovative Phase Change Material slurry for both the heat transfer fluid and storage media. The formulation of a model predictive controller of such a closed-loop solar system is …
A Two-Level Clustering Strategy For Energy Performance Evaluation Of University Buildings, Kehua Li, Zhenjun Ma, Duane A. Robinson, Jun Ma
A Two-Level Clustering Strategy For Energy Performance Evaluation Of University Buildings, Kehua Li, Zhenjun Ma, Duane A. Robinson, Jun Ma
Faculty of Engineering and Information Sciences - Papers: Part B
This paper presents a clustering strategy to evaluate the energy performance and identify typical daily load profiles of buildings. The cluster analysis included intra-building clustering and inter-building clustering. The intra-building clustering used Gaussian mixture model clustering to identify the typical daily load profiles of each individual building. The inter-building clustering used hierarchical clustering to further identify the typical daily load profiles of a stock of buildings based on the typical daily load profiles identified for each individual building. The performance of this strategy was tested and evaluated using the two-year hourly electricity consumption data collected from 40 buildings on a …
Performance Evaluation Of Full-Duplex Energy Harvesting Relaying Networks Using Pdc Self-Interference Cancellation, Jiaman Li, Le Chung Tran, Farzad Safaei
Performance Evaluation Of Full-Duplex Energy Harvesting Relaying Networks Using Pdc Self-Interference Cancellation, Jiaman Li, Le Chung Tran, Farzad Safaei
Faculty of Engineering and Information Sciences - Papers: Part B
In this paper, throughput and bit error performance of an in-band full duplex (IBFD) relaying system assisted by the radio frequency energy harvesting technique and the polarization-enabled digital self-interference cancellation (PDC) scheme are investigated. In particular, the relay node harvests power from the wireless radio frequency signal transmitted from the source node and uses this power to amplify and forward signals to the destination. Meanwhile, the PDC scheme is used at the relay node to cancel the self-interference signal in order to facilitate the concurrent in-band transmission and reception. The impact of both energy harvesting and self-interference cancellation on the …
