GROUND SOURCE HEAT PUMP

NIBE F1145

NIBE™ F1145 is a heat pump for heating small houses, smaller multi-occupancy houses and industrial premises. F1145 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 intervening heat exchanger. F1145 is also prepared for control of oil, gas-fired or district heating boilers.

installation metHod

The term “ground source” covers four different heat sources:

rock, surface soil, ground water and lake.

Ground water

A viable energy source for any building where ground water is easily accessible.

Ground water can also be utilised as a heat source since it has a temperature of between 4 and 12°C all-year round. The heat pump collects stored solar energy from the ground water. Normally, there is one well for drawing up water and one for returning it.

Lake collector

Cost-effective installation for lakeside homes.

If your home is built beside a water source such as a lake, heat from the lake water can be extracted using a surface soil collector anchored to the bottom of the lake.

Rock - using a ground probe

Ideal for refurbishment or adaptation from a fossil fuel heating system.

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 – 200 metres, depending on the size of heat pump selected. This type of system can be used for all possible building types, large or small, public or private. It requires little space and the ground probe can be drilled in the smallest of gardens.

Surface soil - using a surface collector

Cost-effective energy collection.

During the summer, solar heat is stored in the soil. This is either directly absorbed as insulation or as heat from rain and the air from the near-surface layer of the soil. The heat pump collects this stored solar energy from a buried collector. That is, a hose filled with anti-freeze, and buried at a depth of about 80 – 100 cm, the length of the hose varies between 250 and 400 metres, depending on the size of heat pump selected. Using this energy for heating is a cost effective method. The highest yield can be obtained from soil with a high water content.

How does F1145 work?

Principle of operation

F1145 consists of heat pump, electric heater, low energy circula-tion pumps and control system. F1145 is connected to the brine and heating medium circuits.

The heat from the heat source (rock, soil, lake) is taken up via a closed cooling medium system in which a mixture of water and antifreeze circulates. In some cases, ground water can also be used as heat source. An intermediate heat exchanger should be used to protect the heat pump in such cases.

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 compressor can provide there is an integrated immersion heater.

Transport and storage

F1145 should be transported and stored vertically in a dry place. When being moved into a building, F1145 may be leant back 45°. Note! Can be tail heavy.

If the cooling module is pulled out and transported upright, F1145 can be transported on its back.

Assembly

• Position the heat pump on a firm base, 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 be fitted with sound insulation.

• Route pipes so they are not fixed to an internal wall that backs on to a bedroom or living room.

Installation area

Leave a space of 800 mm in front of the heat pump. Approximately 50 mm free space is required in order to open the side hatches. The hatches do not need to be opened during service, all service on F1145 can be carried out from the front. Leave space between the heat pump and wall behind (and any routing of supply cables and pipes) to reduce the risk reproduction of any vibration.

Drawing out the cooling module

To simplify transport and service, the heat pump can be separated by pulling the cooling module out from the cabinet.

See the installer manual for more comprehensive instructions about the separation.

Pipeinstallation

Pipe installation must be carried out in accordance with current norms and directives. F1145 can operate with a return temperature of up to 58 °C and an outgoing temperature from the heat pump of 70 °C (65 °C with only the compressor). F1145 is not equipped with shut off valves; these must be installed outside the heat pump to facilitate any future servicing.

Pipe connection (cooling medium)

Insulate all indoor brine pipes against condensation.

The level vessel must be installed as the highest point in the brine system on the incoming pipe before the brine pump (Alt. 1). If the level vessel cannot be placed at the highest point an expansion vessel must be used (Alt. 2).

Details of the antifreeze used must be shown on the level vessel. Install the supplied safety valve under the level vessel as illustrated. The entire length of the overflow water pipe from the safety valves must be inclined to prevent water pockets and must also be frost proof.

Install shut off valves as close to the heat pump as possible. Fit the supplied particle filter on the incoming brine pipe.

In the case of connection to an open groundwater system, an intermediate frost-protected circuit must be provided, because of the risk of dirt and freezing in the evaporator. This requires an extra heat exchanger.

Side connection

It is possible to angle the brine connections, for connection to the side instead of top connection.

To angle out a connection:

1. Disconnect the pipe at the top connection. 2. Angle the pipe in the desired direction. 3. If necessary, cut the pipe to the desired length.

Pipe connection (heating medium)

Connecting the climate system

A climate system is a system that regulates indoor comfort with the help of the control system in F1145 and for example radiators, underfloor heating/cooling, fan convectors etc.

• Install all required safety devices, shut-off valves (as close to the heat pump as possible), and particle filter. • The safety valve must have a maximum 2.5 bar opening

pressure and be installed on the outgoing heating medium as illustrated. The entire length of the overflow water pipe from the safety valves must be inclined to prevent water pockets and must also be frost proof. • When connecting to a system with thermostats on all

radiators, a relief valve must be fitted, or some of the thermostats must be removed to ensure sufficient flow.

P

Note! Note that condensation may drip from the level

vessel. Position the vessel so that this does not harm other equipment.

The F1145 can be connected in several different ways.

Free cooling – two pipe systems

PCM 40/42 makes it possible to obtain passive cooling from rock, groundwater or surface soil collectors. When using a surface soil collector the quality of the ground may limit the possiblity to recover passive cooling.

Room temperature sensors can be used for optimum comfort. The lowest permitted flow temperature should be chosen to prevent condensation precipitation.

Active cooling

NIBE F1145 is connected via the HPAC module to the external collector and the building’s climate system for heating and cooling.

The heat exchange from the heat source (rock, surface soil or lake) takes place via a closed brine system in which water is mixed with antifreeze circulates to the heat pump.

Ground water can also be used as a heat source. However, an intermediate heat exchanger is required between HPAC 40 and the ground water.

16 NIBE F1145

installation

Inspection of the installation

Current regulations require the heating installation to be inspected before it is commissioned. The inspection must be carried out by a suitably qualified person and should be documented. The above applies to closed heating systems. If the heat pump is replaced, the installation must be inspected again.

Guideline values for collectors

Control, general

The indoor temperature depends on several factors. Sunlight and heat emissions from people and household machines are normally sufficient to keep the house warm during the warmer parts of the year. When it gets colder outside, the climate system must be started. The colder it is outside, the warmer radiators and floor heating system must be.

The heat pump is controlled by built-in sensors for flow and return brine temperatures (collector). Brine return temperatures can, if so required, be limited to a minimum (e.g. for ground water systems).

Control of the heat production is performed based on the “floating condensing” principle, i.e. the temperature level needed for heating at a specific outdoor temperature is produced guided by collected values from the outdoor and flow sensors. The room temperature sensor can also be used to compensate the deviation in room temperature.

F1145 can be docked to an external unit with its own heating controls. In that case, the heat pump delivers heat up to a fixed temperature level. This is known as “Fixed condensing”. The automatic heating control system is then controlled by the external unit’s regulation device.

Heat production

The supply of heat to the house is regulated in accordance with the chosen setting of the regulating curve (curve slope and offset). After adjustment, the correct amount of heat for the outside temperature is supplied. The flow line temperature of the heat pump will hunt around the theoretically required value. For subnormal temperatures the control system calculates a heating deficit in the form of “degree-minutes”, which means that heating production is accelerated. The larger the subnormal temperature, the greater the heat production.

The heat pump’s control system can control an installed external oil-fired boiler and mixing valve (requires accessory card AXC40).

Hot water production

If the water heater is docked to F1145 when there is a demand for hot water, the heat pump gives this priority and devotes its entire output to water heating. No room heat is produced in this mode. Maximum time for hot water charging can be adjusted in the menu system. After this, heating is produced for the remaining period of time before further water heating can take place.

Hot water charging starts when the hot water sensor has fallen to the set start temperature. Hot water charging stops when the hot water temperature on the hot water sensor (BT6) has been reached.

For occasional higher demand for hot water, the “temporary lux” can be used to raise the temperature for 3 – 12 hours (selected in the menu system).

For use with 40 x 2.4 PN 6.3 PEM hose.

The length of the collector hose varies depending on the rock/soil conditions, climate zone and on the climate system (radiators or underfloor heating).

Max length per collector should not exceed 400 m.

In those cases where it is necessary to have several collectors, these should be connected in parallel with the possibility of adjusting the flow of the relevant coil.

For surface soil heat, the hose should be buried at a depth of about 1 metre and the distance between the hoses should be at least 1 metres.

For several bore holes, the distance between the holes must be at least 15 metres.

Ensure the collector hose rises constantly towards the heat pump to avoid air pockets. If this is not possible, air vents should be used.

As the temperature of the brine system can fall below 0 °C it must be protected against freezing down to -15 °C. One litre of ready mixed brine per meter of collector hose (applies when using PEM-hose 40 x 2.4 PN 6.3) is used as a guide value when making the volume calculation.

NIBE F1145 17

Additional heat only

F1145 can be used exclusively as an additional heater, to produce heat and hot water, for example before the collector installation is complete.

Brine pump

The brine pump normally follows the operation of the heat pump. There is a special operating mode for continuous operation for 10 days, followed by return to normal mode (this may be used before stable circulation has been established).

Alarm indications

The status lamp lights red in the event of an alarm and the display shows detailed information depending on the fault. An alarm log is created with each alarm containing a number of temperatures, times and the status of outputs.

Own curve

F1145 has pre-programmed non linear heating curves. It is also possible to create an own defined curve. This is an individual linear curve with one break point. You select a break point and the associated temperatures.

Under floor drying

F1145 has an integrated floor drying function. This allows for controlled drying of a concrete slab. It is possible to create your own program and to follow a pre-programmed time and temperature schedule.

Electrical addition

Heat pumps are not usually dimensioned to provide the entire heat output requirement, which is why additional output is necessary during cold days. The immersion heater is automatically switched on (in seven steps) if the output is not sufficient to reach the temperature levels requested by the control computer.

Oil addition

F1145 can be docked to an oil-fired boiler using accessory card AXC40 to provide additional heat during cold days. If F1145 cannot meet the output requirement the oil boiler’s burner is permitted to start. When the boiler temperature has been increased to about 55 °C, F1145 activates the mixing valve, which then opens. The mixing valve adjusts so the true flow temperature corresponds with the control computer’s theoretical calculated set point value. When the heating requirement drops sufficiently so the additional heat is no longer required the shunt closes completely. However, the oil boiler will be kept warm for a further 12 hours to be prepared for any increase in the heating requirement.

USB service outlet

F1145 is equipped with a USB socket in the display unit. This USB socket can be used to connect a USB memory to update the software, save logged information and handle the settings in F1145.
