Experimentelle Untersuchung eines Kältekreislaufs in einer modularen Wärmepumpe für Wohnanwendungen

In Vienna alone there are up to 440.000 gas boilers in use, which burn natural gas to heat living spaces and prepare domestic water. Heating occurs according to the continuous flow principle, which means that gas boilers only work when heat is required. However, burning natural gas produces greenhouse gases, which are partly responsible for global warming. In addition, a large proportion of natural gas comes from foreign imports, which leads to a massive dependency in the energy sector. In order to pave the way to decarbonisation of the heating and cooling sector and to promote the expansion of renewable energy sources, a functional model of a modular heat pump developed by Ochsner Wärmepumpen GmbH is to be experimentally examined at the Austrian Institute of Technology GmbH. The aim of this work is therefore to implement a measurement concept on a heat pump test bench, which has been newly adapted for the experimental measurements. The results of this experimental measurement are intended to help ensure that a decentralized and sound-optimized heat pump solution can be developed as a drop-in alternative for residential applications in order to replace gas boilers in the future. The heat pump module is examined at various operating points to determine whether such a retrofit is technically possible. This is intended, on the one hand, to initiate the decarbonisation of electricity generation and, on the other hand, to reduce dependence on the energy market.
