F1245 – An excellent choice

F1245 is part of a new generation of heat pumps, which have been introduced

to supply your home with inexpensive and environmentally friendly heating

and/or cooling. Heat production is safe and economical with integrated water

heater, immersion heater, circulation pump and control system.

The heat pump can be connected to an optional low temperature heat distri-

bution system. e.g. radiators, convectors or under floor heating. It is also

prepared for connection to several different products and accessories, e.g.

extra hot water heater, ventilation recovery, pool, free cooling and climate

systems with different temperatures.

An immersion heater of 9 kW (if 1 phase, 7 kW) can be connected automat-

ically if anything unforeseen should occur or as reserve operation (then 6

kW).

F1245 is equipped with a control computer for good comfort, good economy

and safe operation. Clear information about status, operation time and all

temperatures in the heat pump are shown on the large and easy to read

display. This means, for example, that external unit thermometers are not

necessary.

Excellent properties for F1245:

႑Integrated water heater

There is a water heater integrated in the heat pump, which is insulated

with environmentally friendly cellular plastic for minimal heat loss.

႑Scheduling the indoor comfort and hot water

Heating and hot water as well as cooling and ventilation in some cases,

can be scheduled for each day of the week or for longer periods (vacation).

႑Large display with user instructions

The heat pump has a large display with easy-to-understand menus that

facilitate setting a comfortable climate.

႑Simple troubleshooting

In the event of a fault, the heat pump display shows what happened and

the actions to be taken.

Heat pump function

A heat pump can use stored solar energy from rock, ground or water in order

to heat a property. The conversion of stored energy in nature to property

heating occurs in three different circuits. In the brine circuit, (1) , free heat

energy is retrieved from the surroundings and transported to the heat pump.

In the refrigerant circuit, (2) , the heat pump increases the retrieved heat's

low temperature to a high temperature. In the heating medium circuit, (3) ,

the heat is distributed around the house.

Brine circuit

In a hose, collector, an anti-freeze liquid, brine, circulates from the heat pump

out to the heat source (rock/ground/lake). The energy from the heat source is

stored by it heating the brine a few degrees, from about –3°C to about 0 °C.

The collector then routes the brine to the heat pump’s evaporator. Here, the

brine releases heat energy and the temperature drops a few degrees. The liquid

then returns to the heat source to retrieve energy again.

Refrigerant circuit

Another liquid circulates in a closed system in the heat pump, a refrigerant, which

also passes the evaporator. The refrigerant has a very low boiling point. In the

evaporator the refrigerant receives the heat energy from the brine and starts to

boil.

The gas that is produced during boiling is routed into an electrically powered

compressor. When the gas is compressed, the pressure increases and the gas's

temperature increases considerably, from 5 °C to approx. 100 °C.

From the compressor, gas is forced into a heat exchanger, condenser, where it

releases heat energy to the heating system in the house, whereupon the gas is

cooled and condenses to a liquid form again.

As the pressure is still high, the refrigerant can pass an expansion valve, where

the pressure drops so that the refrigerant returns to its original temperature. The

refrigerant has now completed a full cycle. It is routed to the evaporator again

and the process is repeated.

Heat medium circuit

The heat energy that the refrigerant produces in the condenser is retrieved by

the heating system's water, heating medium, which is heated to 35 °C (supply

temperature).

The heating energy that the refrigerant releases in the condenser is retrieved by

the heat pump's boiler section.

The heating medium circulates in a closed system and transports the heated wa-

ter's heat energy to the house water heater and radiators/heating coils.
