The objectives of the present work is to theoretically and experimentally demonstrate the advantages of a two-stage cycle equipped with an economizer and single variable speed compressor for heat pumps using air as cold source. Furthermore, an efficient de ...
Heat exchanger for a motor vehicle cooling system including a sleeve-like meter hermetically mounted on, and surrounding, a hollow tubular chassis meter of the vehicle. The sleeve is provided with inlets and outlets communicating with the space between the ...
Starting with a classical process for producing methanol using the reforming and synthesis steps, a combined approach applying simulation models and a new synthesis strategy, named Effect Modelling and Optimisation (EMO), has been used to optimise the ener ...
This paper presents results for the minimization of fuel consumption in a batch furnace. Several different criteria are used and minimized with respect to time- dependent process and control variables. As would be expected, the results show that globally t ...
Several years ago it has been demonstrated experimentally and verified theoretically that Vuilleumier heat pump systems (a combination of a Stirling engine with a Stirling heat pump) can be supercharged periodically by means of an attached resonance tube, ...
The Swiss limit for NOx exhaust gas emissions from decentralised electrical power and heat cogeneration units using stationary I.C. engines operating on natural gas, despite a recent increase from 80 to 250 mg/mN3 (5% O2), remains the most severe in force ...

In the frame of the decentralised electrical power and heat cogeneration with stationary I. C. engines operating on natural gas, the Swiss limit for exhaust gas emissions, with 80 mg/mN3 (5% O2), is the most severe in force on an international level. On th ...
The technology gap between liquid and gaseous fuels presents an obstacle in realising the environmental and performance potential of CNG vehicles. Therefore a gaseous fuel injector has been developed to cope with the considerable larger volume flow rated r ...
