A new model for predicting the thermal and electrical performance of solid-oxide fuel cell(SOFC) cogeneration devices for residential buildings has been developed and demonstrated. This is a system-level model that considers the thermodynamic performance o ...
A new type of air-water heat pump has been developed with the aim to cover an extended application range in high temperature residential heating (for retrofitting existing oil or gas boilers in hydronic heating systems). The base heat output is about 10 kW ...
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 ...
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 project High Temperature Heat Pump has been completed in 2 phases. First a new type of scroll compressor with adapted injection port for vapor injection, was tested with an air-water heat pump (fig 2.2, 2.3). This type of heat pump reaches the extreme ...
This paper describes the working principle of a DC magnetohydrodynamic (MHD) micropump that can be operated at high DC current densities (J) in 75-μm-deep microfluidic channels without introducing gas bubbles into the pumping channel. The main design featu ...
A brine/water heat pump with the auxiliary liquid subcooling cycle with a heating capacity of 9 kW at -7/50°C was built and a series of measurement were conduced. The heat pump is designed for the monovalent heating in the retrofit market. For this purpose ...
This thesis presents a system approach with the aim to develop improved concepts for small capacity, high temperature lift air-water heat pumps. These are intended to replace fuel fired heating systems in the residential sector, which leads to a major redu ...
A new model for predicting the thermal and electrical performance of solid- oxide fuel cell (SOFC) cogeneration devices for residential buildings has been developed. This is a system-level model that considers the thermodynamic performance of all component ...
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 ...
