Bei Förderprogrammen steht eine hohe Bedürftigkeit knappen öffentlichen Mitteln gegenüber. Deswegen sollten sie wirksam sein. Das trifft auch auf neuere Förderprogramme zu, die einkommensschwachen Haushalten helfen sollen, ihre Energiekosten zu senken. Ein wichtiges Förderinstrument sind...

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...

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...

Experimental investigations have been carried out on a glass bubble absorber with swirl entry of air into absorber water column to understand the bubble hydrodynamic characteristics. The swirl motion to the air bubbles is imparted with the help of cavity type swirl generator. Numerical...

In the present paper, a multi-target temperature ejector-expansion subcooler vapor-injection (MTES) refrigeration cycle is proposed in order to improve the performance of natural fluid CO2 refrigeration cycles. In this respect, a thermodynamics model to simulate a two-phase ejector cycle...

Rapid growth in global incomes and the world’s affluent population, coupled with changing consumer tastes and frequent shocks to food supplies, places unprecedented pressures on the world’s food demand and supply balance, and by extension, the worldwide “cold-chain” food transportation...

Sparsam mit Strom und Wärme umzugehen - das ist für einkommensschwache Haushalte aufgrund der hohen Energiepreise noch wichtiger geworden. Einen bedeutenden Ansatzpunkt bietet dabei der Umstieg auf ein energieeffizientes Kühlgerät. Gerade einkommensschwache Haushalte betreiben ihr...

In this study, a new application of a Tesla turbine (TT) is presented in which a TT is introduced as a promising solution to enhance the energy efficiency of refrigeration cycles. For this special purpose, a TT is represented as a regenerative system that minimizes the wasted energy without...

The use of graphene nanolubricant to enhance the performance of eco-friendly refrigerant (R600a) in a vapour compression system was investigated. The graphene nanoparticles were dispersed in the base lubricant and prepared for three different samples of graphene nanolubricant concentration of...

Vapour compression refrigerator systems working with R134a are associated with high energy demand and environmental problems and refrigerator consumers' prioritise energy consumption in choosing their choice of refrigerator systems. Therefore, this research work investigated R600a in...

Refrigerants are promising targets for private environmental governance initiatives. An unintended consequence of the 1987 Montreal Protocol was to increase demand for hydrofluorocarbons (HFCs), which are potent greenhouse gases. Global demand for air conditioning units and other...

When preserving perishable goods, maintaining a constant temperature over the cold supply chain is essential. Therefore, refrigerated vehicles are an important part of the cold supply chain system. However, many traditional refrigerated cargo systems are not designed to support the homogeneity...

This paper examined the determinants of eco-innovation from an evolutionary economics perspective. The focus was on consumer demand (pull) as a determinant of eco-innovation in the sale of consumer appliances (refrigerators). The research also addressed the effect of life cycle costing (LCC) and...

Variable refrigerant flow (VRF) systems are known for their high energy performance and thus can improve energy efficiency both in residential and commercial buildings. The energy savings potential of this system has been demonstrated in several studies by comparing the system performance with...

The ENERGY STAR certification is a voluntary labeling that favors the adoption of energy efficient products. In the US appliance market, the label is a coarse summary of otherwise readily accessible information. Using micro-data of the US refrigerator market, I develop a structural demand model...

The Rent to Own "RTO" industry is accessible to all consumers regardless of financial background. There are no credit checks or price variances based on the customer's credit score. Some RTO customers are more valuable than others and give RTOs significant incentives to pursue customers who...

The purpose of this research is to estimate the potential effect of carbon pricing on the purchase of energy efficient appliances, using refrigerators as a representative appliance. Carbon emissions are widely believed to be contributing to climate change, although the U.S. has not yet...

Energy efficiency regulation is an important driver for innovations in environmental technologies. Improvements of energy efficiency do not only contribute to reach envi-ronmental policy targets, they can be furthermore economically profitable. E.g. private households can reduce their costs in...

"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...

This paper contains the dataset for the refrigerator case concerning the design of a production and return network for refrigerators. Section 1 emphasises the major changes to the problem structure and assumptions used by Umeda et al. (1999). Section 2 contains the parameter settings. Section 3...
