NIBE™ F1345 GROUND SOURCE HEAT PUMP 2 STAGE HEAT PUMP WITH ROCK, EARTH, LAKE OR GROUND WATER AS HEAT SOURCE. • ess than 3 kg refrigerant per cooling section/installation. L This means no inspection requirement. • he two scroll compressors can supply up to 65°C to the T heating system. • ouble compressors give better power control, longer operD ating intervals, less wear and greater operational security. • Display unit with easy-to-read colour screen. – See status and make settings via SMS with the SMS 40 accessory. – Control the heat pump externally, with for example BMS, via the accessory MODBUS 40. • he heat pump is available in the following sizes: 24, 30, 40 T and 60 kW. • p to 540 kW with 9 x F1345 in the same system. U • Soft start relays and load monitor factory installed. • nternally installed low energy circulation pumps (not brine I pump for 40 or 60 kW). • repared for pool heating with POOL 40 accessory. P • repared for control of up to four heating systems with P ECS40/ECS41 accessory. • Coefficient Of Performance (COP) up to 4.51 at 0/35 C according to EN 14511. • eparate cooling modules for compressors and brine pumps S give reliable service and lower noise levels. • asy to remove the cooling modules. E • NIBE Uplink compatible NIBE F1345 NIBE F1345 is a heat pump for heating large buildings, such as apartment buildings, churches and industrial premises. F1345 is a flexible product with advanced control equipment and can be adapted to several system solutions. The ground, bedrock or lakes can be used as the heat source. Groundwater can also be used as a heat source, but this requires an intermediate heat exchanger. Another area of use could also be ventilation recovery in multioccupancy buildings. F1345 can control up to four different climate systems (requires accessory), for example a lower flow temperature in the underfloor heating loops than in the radiators. F1345 is also prepared for control of an external additional heater. At hot water production this can be prioritised, selectable with one or more compressors. This permits simultaneous production of heat and hot water.

INSTALLATION METHOD The term “ground source” covers four different heat sources: rock, surface soil, ground water and lake. Rock - using a ground probe Surface soil - using a surface collector Ideal for refurbishment or adaptation from a fossil fuel heating system. Cost-effective energy collection. In the lower subsoil of the so-called “near-surface geothermal layer” lies a heat source with an almost constant temperature that can be utilised all year round. The heat pump collects stored solar energy from a collector in a hole drilled into the rock. The depth of the hole can vary between 90...

HOW DOES F1345 WORK? Principle of operation F1345 consists of two heat pump modules (cooling module), 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 antifreeze, 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,...

GOOD TO KNOW ABOUT NIBE F1345 Transport and storage F1345 should be transported and stored vertically in a dry place. Position F1345 on a firm base that can take the weight, preferably on a concrete floor or foundation. Use the heat pump’s adjustable feet to obtain a stable set-up. Install with its back to an outside wall, ideally in a room where noise does not matter, in order to eliminate noise problems. If this is not possible, avoid placing it against a wall behind a bedroom or other room where noise may be a problem. Wherever the unit is located, walls to sound sensitive rooms should...
