About your heat pump
4.1
Product description
This heat pump is a heating system for both heating and hot water production. It has a compressor which is
customised for heat pumps.
The heat pump is equipped with control equipment which is presented in a graphic display. The heat pump is
also prepared for monitoring via the internet. (Accessory Online)
Heating is collected from a ground collector and is provided to the building via a water-borne heating system.
The heat pump (compressor) supplies as much of the heat demand as possible before auxiliary heating is en-
gaged to assist. If cooling is installed, the heat pump can also provide cooling.
The heating unit consists of some different components:
Heat pump unit
The heat pump consists of e.g.:
▪
Scroll compressor
▪
Stainless steel heat exchanger´s
▪
Speed controlled, low energy circulation pumps for collector system and heating system
▪
Inbuilt stainless water heater
▪
Internal electrical immersion heater
▪
The Duo heat pump has a separate water heater. The temperature in the water heater is controlled by
temperature sensors.
Control equipment
The control equipment controls the incoming components of the heating appliance (compressor, circulation
pumps, auxiliary heating, exchange valves and external functions available as accessories, if installed) and
keeps track of when the pump should start and stop, as well as whether it should produce heating or hot water.
The control equipment consists of:
▪
Control display.
▪
Temperature sensors e.g. (outdoor, supply line, return line, brine and hot water).
▪
Pressure switches.
Heating system
In your heating system, water is constantly circulating from the heat pump through radiators or floor heating
and back again to provide heating to the building, except during summer when there is no need for heating. If
you have cooling installed, the cooling is supplied in a similar way, often to fan coils or under floor systems
prepared for cooling.
