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...
