This study analyzes the changes that have occurred in food logistics in the three years since the emergence of the COVID-19 pandemic and the one year since the war in Ukraine commenced. Food logistics companies are highly sensitive to demand shocks, energy prices, and staff availability. In this...

By expanding the theory of planned behavior with Structural Equation Modeling, the objective of the study is to investigate consumer behaviors in the purchasing of fresh food through fresh-food apps and cold chain logistics services usage in Shanghai and Beijing, China. The results showed that...

Purpose - This article aims to evaluate published food cold chain (FCC) literature against risk management and supply chain sustainability concepts. Design/methodology/approach - The article uses the theory refinement logic proposed by Seuring et al. (2021) to analyze the contents of FCC...

We study the impact of text message based information on the household use of air conditioners in southern China using a two-staged clustered randomized experiment among 484 households. In the first stage, we send specific information on how to use air conditioners efficiently to one third...

Air Cargo plays a key role under the global supply chain crisis brought about by COVID-19 pandemic. This study aims to analyze empirically the transport patterns and correlations of key commodities of cold chain in air cargo. We analyzed air cargo O-D data by weight for key commodities including...

With the adoption of the EU Climate Law in 2021, the EU has set itself a binding target to achieve climate neutrality by 2050 and to reduce greenhouse gas emissions by 55 percent compared to 1990 levels by 2030. To support the increased ambition, the EU Commission adopted proposals for revising...

The overall objectives of this study are to contribute to optimal pathways for decarbonisation of heating and cooling. The study depicts the perception or image of heat pumps and district heating and cooling among different consumers in the residential, industrial and public sectors, and...

This report was created within the project "Overview of Heating and Cooling: Perceptions, Markets and Regulatory Frameworks for Decarbonisation." The focus of this report is on the evaluation of the final cost for owning and operating district heating (DH) connections and heat pumps (HPs) for...

With the improvement of people's living standards all over the world, the demand for cooling (both space cooling and refrigeration) continues to grow. The increase in cooling-related energy consumption has a growing impact on global climate change. The importance of improving the energy...

Refrigerant is the working medium of refrigeration and air-conditioning systems. Currently, synthetic refrigerants are the dominant refrigerants for cooling, but the emissions from synthetic refrigerants into the atmosphere will destroy the ozone layer. The global refrigeration and...

The quality of perishable products declines continuously during the transportation process, rendering the delivery of a product with good freshness a challenging task in urban areas. We investigate how to plan the activities to preserve the freshness level of products within a specific distance...

Many behavioral responses to climate change are carbon-intensive, raising concerns that adaptation may cause additional warming. The sign and magnitude of this feedback depend on how increased emissions from cooling balance against reduced emissions from heating across space and time. We present...

In this paper, the effects of operating conditions on the energy efficiency of a reciprocating room temperature magnetic refrigerator were experimentally investigated in order to optimise its refrigeration performance. An experimental setup of a magnetic refrigerator allowing the thermal...

District heating grids worldwide are still powered predominantly by combustion of fossil fuels. In order to decarbonize them, new designs for the district heating and cooling systems are required. This paper describes the laboratory at the research center for Combined Smart Energy Systems...

R744 is the most competitive, and R744 is the most ideal when flammability and toxicity are strictly limited. There are some problems in the current R744 heating system, for example the pressure at the heat release side is often more than 10.0MPa. High operating pressure brings high cost....

Numerical simulations of district heating and cooling networks constitute a valuable tool for system design and optimization. This paper presents a novel thermo-hydraulic network model, which addresses particularly large 5th generation district heating and cooling (5GDHC) networks. We paid...

Seaports are regarded as significant actors in global logistics and supply chains since a large part of the cargoes carried over the globe are being processed there. When the cold chain broken down during transport and storage in the ports, the humidity, nutrition, temperature and time...

Heat pumps play an important role in the electrification of the residential sector. The electrification of building energy consumption can have a significant impact on the load management of the electric grid. This study provides the first empirical investigation of the changes in hour-of-day...

Electricity cannot be cost-effectively stored even for short periods of time. Consequently, wholesale electricity prices vary widely across hours of the day with peak prices frequently exceeding off-peak prices by a factor of ten or more. Most analyses of energy-efficiency policies ignore this...
