DSP MINI
a Danfoss Platform for Flensburg Secondary Network
General description and
application
The DSP MINI is designed for use in district heating
networks, suitable for heating and for providing
DHW for single family houses. It provides an alternative solution to an oil or gas boiler. The DSP MINI
is designed for heating, do mestic hot water and floor
heating. The wall- mounted construction saves space
which is needed for installation and service.
The DSP MINI is designed as a wall -mounted sta tion.
Each station is equipped with micro plate heat
exchangers for DHW and optional for heating manufactured by Danfoss, which significantly increase
substation performance and lifetime. All components are placed at the front of the station, which
makes it very easy to access them during maintenance or servicing. The mounting bracket significantly reduces the time required to mount the substation to the wall. The connections are predefined
and allow installers to prepare installation before
station is available on the site, which reduces the
time between deliver y and startup. Piping prepared
with automatic welding machines ensures th e highest possible welding quality.
DSP MINI is equipped with high quality Danfoss
components, which are tested, approved and optimized for safe and reliable operation:
• ECL Comfort 310 controller
• Motorized control valves
• AVTB self-acting temperature controller
• AVPB-F Differential pressure controller with flow
limitation
• Brazed MicroPlate™ Heat exchanger, XB06
• Primary side polyurethane insulation according
50% ENEV 2013
• Metal box with door

Function
AI246186498258en-010202
The DSP Mini substation is the connecting part
between the h eat supplier and the consumer of the
heating and domestic hot water.
The task of the substation is to adapt the heat condition suitable for the consumer and meet the
demand from the heat supplier and consumer.
The water is coming from the district heating utility
and is fed into the station at the appropriate pressure and temperature. This can be higher in winter
and lower in the summer. The district heating water
flows in the primary fl ow through the shut-off valves
and the strainer. Pressure gauges and thermom eters
are installed in the flow and return to detect the
pressure and temperature.
Depending on the variant, the connection of the
secondary side (heating) is carried out directly or
indirectly (via heat exchanger).
Furthermore, on the primary side, in the flow circuit
we have a control valve, depending on the variant,
control valves are used to adapt the heat condi tions
(secondary temperature) by controling the flow of
district heating water. The input s are comming from
using our Danfoss ECL Comfort 310 controller with
weather compensating function.
The district heating water then flows back to the
district heating supply via the primary return
through the shut-off valves and the strainer. On the
primary side, high tem perature connections for radi
ator heating or similar are used depending on the
application selected.
In the secondary circuit, a circulating pump distributes the heating water to the heating devices, this
is available depending on the application.
If the application selected has domestic hot water
production included, this is connected to the primary side and is prepare via a heat exchanger and
with a self-acting control valve.
To limit the flow of primary district heating water,
a flow limiter with integrated differential pressure
control is provided in the return of th e primary side,
here the maximum flow from the contract can be
adjusted. To measure the energy consumed, an
insert for a heat meter is available and M10 connections are provided in the primary side ball valves.
