Product Profile > Junkers Supraeco SAO-2 modulating air/water heat pump

Controlling highly efficient air/water heat pumps via smartphone At Intersolar, Bosch will also be presenting the new Junkers Supraeco SAO-2 modulating air/water heat pump – one of the first on the market to feature a modulating exterior unit. Thanks to a speed-controlled compressor, the Supraeco SAO-2 always supplies only as much energy as is required. This inverter technology makes the heat pump 11 percent more efficient than previous models. Its reduced electricity consumption is reflected in a drop in CO2 emissions, and it is easily adapted to use in detached or semi-detached houses. As standard, the heat circuit's flow temperature never exceeds 62 degrees Celsius during heat pump operation. The Supraeco SAO-2 can actively cool rooms and can be operated via the internet without having to install any additional hardware. The IP gateway required for web communication is already integrated, paving the way for convenient operation via smartphone or tablet. Junkers will soon be introducing its heat pump app JunkersHome. The Supraeco SAO-2 has also been classed “smart grid ready.” Electricity storage/battery system for pioneering housing complex Bosch Energy Storage Solutions will also be at Intersolar, presenting a modular, safe, and turnkey storage solution for housing complexes. The Bosch turnkey storage system uses lithium-ion technology, is around 7 meters wide, 0.6 meters deep, and 1.8 meters tall, and is designed to be installed in an electrical services room. Its capacity and electronics are tailored to the requirements of the complex's power grid. Thanks to its power of 50 kilowatts, the battery can be fully charged or discharged in two hours. Its inverter enables it both to feed electricity into to the grid and to recharge from it. The means by which the battery system is controlled, in combination with Bosch's expertise in the right way to charge and discharge batteries, extends the battery's operating life. Bosch designs, develops, and builds storage systems on a variety of scales all the way up to the megawatt-hour range. Bosch is supplying just such an adaptable energy storage system to a housing complex comprising 180 row houses currently being built in Kelsterbach near Frankfurt. The storage system has an installed capacity of 135 kilowatt hours, which is enough to power ten average four-person households for a day.
