With global climate changing, urban microclimate is deteriorating at a faster rate than before in many cities. In this paper, the significant effect of the deterioration of urban microclimate on air-conditioning energy consumption (ACEC) is studied. Cumulative effect (CE) has enormous influence...

The closed greenhouse is an innovative concept in sustainable energy management. In principle, it is designed to maximize the utilization of solar energy through the seasonal storage. In a fully closed greenhouse, there is not any ventilation window. Therefore, the excess sensible and latent...

Continuous frying systems are very energy intensive. They also involve the interaction of many variables and complex heat and mass transfer processes. Better control of these processes can lead not only to improved product quality but also energy reduction. This paper presents a model that can...

In this paper, two kinds of novel boosting pressure approaches, steam turbocharging and steam-assisted turbocharging, have been proposed. And both are based on the principle of internal combustion (IC) engine exhaust gas energy recovery. In order to demonstrate the advantages of the two types of...

If buildings can change “clothes” according to seasons like human being, the energy consumption for their space heating or cooling will be saved greatly. For this purpose, the thermophysical properties of building external wall should be self-adjusted according to outdoor temperature. In...

In March 2011, China’s central government set a new challenging target of reducing its energy intensity by 16% during 2011–2015, after it had achieved a reduction of 19.1% during 2006–2010. And this new target was assigned to provincial authorities in August 2011. However, China’s...

Following the Japanese Cool Biz campaign which advocated relaxed dress codes and cooling set-points of 28°C in air-conditioned public buildings, other countries have introduced similar policies, with temperature limits varying in different countries. In the UK the British Council for Offices...

Varying water/air volume (VWV/VAV) favors the performance improvement of central chiller systems. However, due to the lack of an intrinsic relation connecting these design parameters to the requirements, both the operating parameters of variable speed pumps/fans (VSP/VSF) and the structural...

Heat Pinch Analysis retrofit projects are typically performed by evaluating and maximising the heat recovery potentials within the individual process units. Once the potential improvements from the individual units have been assessed, the Total Site (TS) Heat Integration analysis is performed....
