A simultaneous optimization of the design and operation of a district heating, cooling and power generation plant supplying a small stock of residential buildings has been undertaken with regards to cost and CO?2 emissions. The simulation of the plant cons ...
The implementation of integrated energy systems within urban areas is a promising CO?2 emissions abatement measure. In this paper on-site heating, cooling and power generation based on a solid oxide fuel cell and gas turbine (SOFC-GT) combined cycle unit a ...
The additional power absorbed by the plasma can be determined from the time derivative of the total plasma energy, which can be estimated from the diamagnetic flux of the plasma using a diamagnetic loop. The main difficulty in using diamagnetic measurement ...
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 ...
Olefins Plants show an intrinsic cost of the energy demand which derives from Process and Plant design. Few innovative changes have been implemented in the past decades. Such changes were mainly directed to increasing the throughput of the plant and its fl ...
The substitution of CFC refrigerants in refrigeration systems, heat pumps and organic Rankine cycles for heat recovery, requires good methods for predicting heat transfer of substitute fluids. The measurements in the LENI test facility (concentric tubes wi ...
A computer system for the promotion of the rational use of energy in the industry has been developed. It combines the PINCHLENI software developed by the LENI (Laboratory of industrial Energy Systems) of the Swiss Federal Institute of Technology (Lausanne) ...
Replacing conventional boilers by air to water heat pumps represents a major market opportunity and a contribution to more sustainable heating approaches. However, such retrofit situation impose tough technical requirements which must be met in order to de ...
A new Thermodynamic Approach for modelling mixtures of refrigerants and lubricating oils is presented. The model includes generalized methods for predicting the following thermodynamic properties of refrigerant-oil mixtures: bubble point temperatures, loca ...
In this paper, a district heating, cooling and power generation unit has been evaluated from the viewpoints of cost and CO2 emissions. The superstructure considered includes a solid oxide fuel cell and gas turbine (SOFC-GT) combined cycle, a compression he ...
