GAHP W

Water-to-water
Gas Absorption Heat Pump (Water Source)

 

For Heating, Cooling and DHW production simultaneously.

Benefits

  • The heat pump benefits from Robur's Summer Rebate for the USA.
  • Ultra efficiency unit: efficiency over 139% providing heating and cooling simultaneously.
  • No need of cooling towers and back-up boilers resulting in reduced plant and running costs.
  • 92% reduction in electrical power requirement (0.4 kWe per 132,400 BTU/h of heating output and 54,600 BTU/h kW of cooling output), compared to traditional electrical systems.
  • Single Phase Power.
  • Complete flexibility and modularity to increase seasonal performance factor and total heating and cooling capacity.
  • No need to increase electric power demand.
  • For applications requiring standby power, the electric output requirements will be lower.
  • High Reliability due to few moving parts inside the unit.
  • Easy Maintenance, similar to gas fired boilers.
  • No use of Harmful Refrigerants.
  • Indoor Installation.

Applications

RESIDENTIAL and COMMERCIAL (swimming pools, hospitals) hydronic simultaneous heating and cooling systems:

  • radiant floor or ceiling;
  • fan coil and air handlers;
  • cast iron radiators;
  • year-round DHW production;
  • free or active cooling mode available.

INDUSTRIAL applications (manufacturing cycles or liquid-ring-based air conditioning systems) with high year-round simultaneous heating and cooling demand:

  • air handlers unit, A.T.U.
