Gas engine heat pump
Gas engine heat pump
with AHU kit
As an air-to-air system, the gas engine heat pump situated in the outside area is connected in classic split construction with a refrigerant-bearing register in a ventilation unit. As a result of the direct connection of the gas engine heat pump and the AHU kit on
the ventilation unit, complex installations can be avoided and frost protection measures dispensed with.
The system is suitable for monovalent operation as a result of the internal use of the engine and exhaust heat. Moreover, this heat is used for defrosting the registers without heating interruption.
- Low electrical power consumption, thus relieving the load on the power grids
- Transformer stations or emergency power systems may be dimensioned smaller or can be omitted completely
- Cascades are easy to create and promote operational safety
- Lower CO2 emissions compared to boilers and electric chillers
- Universal use for heating, cooling and dehumidifying, as well as post-heating via the engine heat recovery
- Up to 85 kW cooling capacity and 95 kW heating capacity via a single-circuit register
- Power adjustment by means of modulation
- Engine waste heat can be recovered and reused
- No frost protection measures necessary
- Direct heating and cooling transfer from refrigerant to air, thus hardly any conversion losses
- No heating interruption in defrost mode

VENTILATION KIT
The AHU kit forms the interface between the superordinate controller of a ventilation system or building control system and the gas engine heat pump.
As a result of specifying the type of operation and an infinitely variable capacity request, the gas engine heat pump is controlled in an energy efficient manner via the AHU kit.
- Self-explanatory simple operation
- Web connection via Modbus or optionally via Ethernet
- Modbus connection for BMS already available, BACnet optional
- Clear display of operating states and setpoints or actual values
- All main functions are preset
- Cascade connection of up to eight gas engine heat pumps
