Application

Application
Inverter geothermal ground source heat pump with output-dependent control for indoor installation. Can be used in mono mode to provide heating and hot water. With the help of additional hydraulic components, the existing source system can be used for passive and active cooling, or even for simultaneous heating and cooling. Suitable for apartment buildings and commercial applications. For high heating output, up to 16 heat pumps can be connected in a cascade. Vertical Design ensures minimal installation footprint.

Equipment
The integral inverter makes the heat pump extremely flexible and versatile, enabling it to be installed in different types of buildings. The inverter continually adapts the heating output of the heat pump to the amount of energy currently required. One high-efficiency circulation pump is provided for the brine side and one for the heating side. During normal heat pump operation, the hot gas technology enables the hot gas to be utilised directly to heat the DHW via an additional heat exchanger simultaneously. The integral heat pump controller with colour touchscreen enables fully automated, weather-compensated control of the heating system and, when combined with the optional ISG, the ability to control the system via a home network or a mobile terminal device. External control of the heating system by a building management system is possible as an option. To minimise the transfer of structure-borne sound to the building, the refrigerant circuit is mounted on an anti-vibration base plate, and its hydraulic connections are flexible. The refrigerant circuit is hermetically sealed, tested for tightness at the factory and filled with safety refrigerant R410A.

Efficiency
The installed inverter ensures optimum heat pump operation all year round and consequently, maximum efficiency. The integrated Desuperheater Exchanger enables high hot water temperatures to be achieved very efficiently and at a low cost.InstallationInternal pressure hoses allow a direct hydraulic connection to the heating and brine circuits. The high level of integration ensures quick and simplified installation, even with larger systems. The appliances are fully installed and delivered ready for operation.
