Indoor unit.

NIBE F1345 is a powerful, flexible ground source heat pump which is available in four output sizes. Up to nine NIBE F1345s can be combined in a single system to cover output requirements of up to 540 kW.

Two large compressors make NIBE F1345 particularly suitable for properties with larger heating requirements, centralised systems and commercial premises. The compressors are switched on and off automatically for better output regulation, a longer operating range, less wear and tear and improved reliability.

The F1345 product is suitable for traditional borehole or surface collector systems, in addition to open loop and closed loop water fed systems. The F1345 is also suitable for ambient loop applications and innovative PV-T panels solutions.

Thanks to smart technology, the product gives the user control over energy consumption and the efficient control system automatically adjusts the indoor climate for maximum comfort.

Features and benefits:

• Output sizes: 24, 30, 40 and 60 kW.
• Powerful, flexible system that covers output requirements of up to 540 kW.
• Reliable system with efficient output regulation and no requirement for annual inspection.
• Smart technology with user-friendly control for optimal remote control.
• Integrated underfloor drying function.
• Clear and easy to use control display.
• A wide range of system solutions and accessories.
• 1950 mm required ceiling height.
• Constructed on a robust frame with durable panels and effective soundproofing for the best possible comfort - All panels are easy to remove to facilitate installation and for any servicing.

Operation:

F1345 consists of two heat pump modules, circulation pumps and control system with possibility of additional heat. F1345 is connected to the brine and heating medium circuits.

In the heat pump evaporator, the brine (water mixed with anti-freeze, glycol or ethanol) releases its energy to the refrigerant, which is vaporised in order to be compressed in the compressor. The refrigerant, of which the temperature has now been raised, is passed to the condenser where it gives off its energy to the heating medium circuit and, if necessary, to any docked water heater. If there is a greater need for heating/hot water than the compressors can provide it is possible is to connect an external immersion heater.
