The new heat pump system is based on a thermal sensor based on a sensorlay-out-out-out-out-out-out-out-out-out-out-out-out. Allegedly, this technology is effective to prevent propane from forming a bright mixture with air outside the device.
German heating specialist Vaillant and the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) have presented a new heat pump concept at the Ish Frankfurt Trade Fair this week.
“The new device is the result of many years of close cooperation between us and Vaillant,” said the Fraunhofer Isee in a statement. ‘Eight years ago we started developing a heat pump that could be installed flexibly indoors and connected to existing heating systems with the help of climate -friendly propane (R290) coolant. “

This technology is reportedly effective in Prevents propane from forming a missing mixture with air outside the device. This mechanism uses a physical and technical principle that is known as adsorption, which in the event of damage prevents propane from escaping from the cooling circuit to adhere to the surfaces of very porous structures made of activated carbon.
‘Thanks to this principle, the heat pump can be installed anywhere in the building, “said the Fraunhofer Isee. ‘In addition, it makes it ideal for replacing heating systems in existing buildings. “
The heat pump system has been developed under the Safesen Research project, which ran from 2020 and 2022.
“The aim of the collaborative project is to ensure that heat pumps can work safely throughout their entire life cycles, which improves market acceptance for the use of heat pumps with natural coolants to offer heating and hot water in houses with one and multi -family homes, while the environmental friendliness of heat pump technology is also improved,” the research project of the research project.
The Fraunhofer Isee has also developed a cooling circuit for heat pumps that use propane as a coolant in the research project “LC150 Development of a coolant-reduced heat pump module with propane”, funded by the German Federal Ministry for Economic Affairs and Energy (BMWI).
In the frame of this project, the Fraunhofer Isee developed a brine water cooling circuit with the help of components available on the market. “The circuit requires only 150 grams of propane for a heating capacity of 8 kW, which corresponds to a coolant reduction of 75% compared to systems on the market,” said the research institute. “A heat pump based on this concept can be placed in the house, as a fridge, without extra safety measures.”
