This paper analyzes the impacts of the modified needs for space heating and cooling due to global warming on the quantities of energy used for space conditioning and overall. It thereby estimates direct and total rebound effects, the latter including changes in consumption and production...

While the first phase of the energiewende, focusing on the electricity sector, was largely successful, the second phase needs to focus on all energy usage, especially heat, transportation, and usage as a raw material in the chemical industry. In that context, intensified "sector coupling" will...

"This book considers the details of the technologies that made ice production, storage, and transportation possible, how the technologies that made up this system improved over time, and the many effects of these improvements on the people that benefited from these changes. While increased...

Recent droughts and heat waves have revealed the vulnerability of some power plants to effects from higher temperature intake water for cooling. In this evaluation, we develop a methodology for predicting whether power plants are at risk of violating thermal pollution limits. We begin by...

Solar air collectors have various applications: on the one hand, they can be used for air heating in cold seasons; on the other hand they can be used in summer to evacuate the warm and polluted air from residential, offices, industrial, and commercial buildings. The paper presents experimental...

The design of a four-bed three-stage adsorption cycle has been proposed to reduce the volume of the six-bed three-stage adsorption cycle. A simulation model for the proposed innovative cycle was developed to analyse the influence of cycle time on the system performance identifying the specific...

Increasingly strict energy policies, rising energy prices, and a desire for a positive corporate image currently serve as incentives for multinational corporations to reduce their plants’ energy consumption. This paper quantitatively investigates and discusses the value of a traditional...

A 2D unsteady computational fluid dynamics (CFD) model is employed to simulate buoyancy-driven turbulent ventilation in attics with different pitch values and ceiling insulation levels under summer conditions. The impacts of roof pitch and ceiling insulation on the cooling load of gable-roof...

Verena Brenner provides a systematic approach for the investigation, measurement, and management of supply chain disruptions. A terminological, theoretical and practical basis for the analysis of supply chain disruptions is developed to create a consistent and transferable research framework. To...

In a modern greenhouse there are a number of alternative systems that can be deployed to control the climate, and the choice what to use and when is not easy for the grower. A novel management system is proposed, consisting of an energy input minimizing module, and a module to realise the...

A thermoelectric (TE) cooler architecture is presented that employs thin film thermoelectric elements on a plastic substrate in a corrugated structure sandwiched between planar thermal interface plates. This design represents a hybrid of a conventional bulk TE device and an in-plane thin film TE...

Single cooling and desalination technologies require a high amount of energy to produce cooling and fresh water, respectively. Coupling these systems seems to be attractive not only to reduce their energy consumption rates and to gain more flexibility in operation but also for environmental...

This paper presents a modeling and optimization investigation of a solar driven adsorption cooling system working with activated carbon–methanol pair. It deals with the effect of internal fins on the thermal behavior of the adsorber and on the system performance. A two-dimensional model...
