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 ...
Although heat pump based district heating is often an obvious solution, adapting the delivery temperature to the most exigent users is detrimental to overall system performance. This pitfall can be avoided with a centralized plant of heat pumps, cogenerati ...

The Laboratory of Industrial Energy systems has evaluated a series of high performance air-water heat pump concepts with the aim to retrofit existing fuel fired boilers for residential hydronic heating systems. The results are published within the framewor ...
Intube flow boiling experiments for refrigerant R-134a mixed with a lubricating oil are reported for a plain, horizontal tube. The tests were run at a nominal inlet pressure of 3.4 bar over a wide range of vapor qualities at mass velocities of 100, 200, an ...
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 ...

The capacities of performance improvements of low and mid-size heat pumps are studied in this project. For the new buildings market, the components of the heat pump match already well the requirements for high performance and monovalent heating. Minor impr ...
Two-phase flow pattern data have been obtained experimentally for R-407C flowing inside 12 mm bore sight glasses, which were located at the outlets of 3 m long, plain bore copper tube heat transfer test sections. The tests covered nominal mass velocities o ...
