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...

Energy scarcity in various regions worldwide not only adversely affects people's quality of life but also hinders overall development. Pakistan is among the nations grappling with energy shortages, with high consumption and limited generation, resulting in a substantial energy shortfall of 2500...

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...

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...

Data centres (DCs) are large electricity consumers, estimated to account for around 1% of worldwide electricity usage. They release excess heat (EH) during the operation, which can be recovered in district heating (DH) networks. DCs are expected to satisfy the rising demand for digital services....

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...

Lack of cooling and cold-chain access is a critical development challenge that has significant implications for people's livelihoods, productivity, health, food, and nutritional security. While business-as-usual demand projections suggest 19 new cooling appliances will be sold every second by...

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....
