AIT DEVELOPS DECENTRALIZED HEAT PUMPS TO REPLACE GAS BOILERS

25.01.2023
Ochsner Wärmepumpen and AIT - Austrian Institute of Technology are working on a joint project to develop a modular heat pump with environmentally friendly refrigerant as a gas boiler replacement in large-volume residential buildings.
 

Across Austria, there are still around 800,000 gas-fired floor heating systems - especially in the cities - 580,000 of them in Vienna alone. On the road to climate neutrality, converting these residential and office units to climate-friendly heating systems is perhaps the greatest challenge. To find a solution for this, Ochsner Wärmepumpen and AIT - Austrian Institute of Technology are working on a joint project to develop a modular heat pump with environmentally friendly refrigerant as a gas boiler replacement in large-volume residential buildings.


DECENTRALIZED, SOUND-OPTIMIZED HEAT PUMPS FOR HEATING, COOLING AND HOT WATER

Because there are hardly any opportunities for individual households in large-volume housing to switch to a heat pump, the gradual refurbishment of multi-apartment buildings with heat pumps is only at the beginning of its success story. Ochsner Wärmepumpen and AIT - Austrian Institute of Technology are working in a joint project on the development of cost-effective, modular heat pumps with environmentally friendly refrigerant. The results of the project are decentralized, sound-optimized heat pumps for heating, cooling and hot water, which, thanks to their compact dimensions, are ideally suited to replace gas boilers in large-volume residential buildings. During operation, a heat storage tank and the development of the heat source are still required.  The heat source is optimally shared by all heat pumps in the building, either using the outside air or geothermal heat. The piping can be routed through the now unused chimney. The modular approach allows easy adaptation to any apartment size and gradual replacement per apartment, without affecting the remaining residential units. 

The "smart" communication of the installed components allows the efficient use of existing heat and waste heat potentials. For example, the waste heat generated during cooling is used to heat water in the summer.
