SECTION 2 OVERVIEW AND TECHNICAL SPECIFICATIONS
This manual supplies information for the installation, operation and servicing of the Robur
Water-Water Gas Absorption Heat Pump GAHP-W and the Robur Water-Water Gas
Absorption Heat Pump GAHP-W LB.
Read this manual carefully before installation.
The Robur GAHP-W (Gas Absorption Heat Pump) is available in 2 versions:
•
GAHP-W: this is a water-to-water gas fired absorption heat pump which has been
designed to recover thermal energy from water sources (wells, rivers, lakes, process
water, etc…). It can be used for heating, cooling and DHW production.
•
GAHP-W LB: this is a also a water-to-water gas fired absorption heat pump which has
been designed to recover thermal energy from the ground through geothermal piping
(not supplied) either vertically or horizontally. It can be used for heating, cooling and
DHW production.
The Robur GAHP-W is controlled by two electronic boards:
- S61 electronic board
- W10
board
The operating temperatures are measured by the following 6 probes:
- Cod water outlet
- Cold
water inlet
- Hot water outlet
- Hot water inlet
- Refrigerant temperature condenser inlet
- Ambient
temperature
Other safety and control devices:
- Manual reset high temperature limit (for sealed system).
- Automatic reset flue gas thermostat.
- Cold water flow switch.
- Hot water flow switch.
- Ignition control box.
- Flue gas pressure switch.
- Oil pump rotation sensor.
