Description
This dataset provides the research data system test results of R-290 (propane) systems. In the TRI-HP project, a new heat pump system with R-290 was integrated into multiple renewable energy sources. There were two experimental campaigns. After analysing the results of the first experimental campaign, the prototype was further improved. The second experimental campaign was conducted with the improved prototype.
The detailed information can be found in ZENODO:
Refined heat pump design and results of final testing
Critical review of heat pump prototype operation and required modications
Experimental results of dual source heat exchanger
The background of this dataset:
During the first experimental campaign, the heat pump prototypes were tested in the laboratories of the project
partners in static conditions. These conditions are defined in standards like, for example, EN 14511 [1], providing
specific temperatures on the evaporator and condenser sides. These tests enable us to characterize the COP and
EER in the nominal conditions of the equipment. However, when such heat pumps are installed in a real building
in a specific climate, they will be subject to varying conditions, depending on the load, the weather along
the seasons, intermediate storage vessels etc. For this reason, it is important also to carry out
dynamic tests.
The dynamic tests presented in this deliverable were performed in two laboratories, following the principles of the
hardware-in-the-loop where part of the systems is installed in the lab (e.g. the heat pump), and part of the systems
is simulated and emulated to provide to real installed systems the response of the virtual element (e.g. building,
ground source, weather, solar thermal and PV). The full methodology and setups are described in detail in the
deliverable D7.1 [2].
The solar-ice system was tested in SPF-OST facilities in Rapperswil, Switzerland. The applied methodology was
the Concise Cycle Test (CCT), where 7 individual days along the year for the given climate of Bern were selected.
The complete system includes solar thermal, ice storage and water storage. The system was assembled in
the laboratory, and the actual setup is described in deliverable D7.3 [3]. The electrical part, including
household electricity, PV and the battery, will be tested for the CO2 slurry system due to time constraints since this
part does not affect the thermal behaviour of the installed system. The full efficiency of the propane solar-ice
slurry system, including the electrical part, will be provided in D7.9, "Demonstrated energetic performance and cost
competitiveness of systems".
The dual-source system was tested in the IREC laboratory SEILAB in Tarragona, Spain. The methodology is slightly
different since the selected periods are not individual days but a series of four consecutive days in
the summer and winter seasons. The overall system includes storage tanks, a geothermal loop as well as
Photovoltaics (PV) and an electrical battery. The assembled system and the lab setup were described in
deliverable D7.2 [4].
The present deliverable compiles the results of these two series of dynamic experiments with the propane heat
pumps. The results of the solar ice system are first analyzed in section 2, including a summary of the laboratory
setup and the control strategies used. The same structure is followed for the dual source system in section 3.
