Request info
Two-pipe heat pump with system-side heat exchanger, able to produce hot or cold water to meet the building's heating or cooling requirements, depending on the season, and DHW.
- Electronic expansion valve (suitable for all operating situations)
- Units with modular power output, thanks to inverter technology
- Climate control included with outdoor temperature sensor
- Larger heat-exchange surface
Energy efficiency class
All versions of Lyra Monobloc 2T are energy class A+++/A++ and therefore benefit from tax deductions in accordance with applicable legislation.
Components
- EC fan
- Twin Rotary Compressor
- Finned pack with hydrophilic treatment
- Heat exchanger with larger rows, large heat-exchange surface
Where can it be installed?
- Suitable for new buildings with high levels of energy efficiency
- Suitable for cold climates such as mountain areas and high T production up to 60°
- Ideal where no mains GAS supply is available
- Suitable for applications with radiant systems, fan coils, thermal ventilation and AHUs

Summer operation
The summer operating modes are:
- Chiller mode
The unit produces only chilled water for the system. - Boiler mode for the production of domestic hot water
If there is no cold load and on request by the domestic hot water probe, the unit heats the water in the domestic hot water storage tank using the finned pack coil as an evaporator. The use of warm outside air as a heat source guarantees extremely high COP levels.


Winter operation
The winter operating modes are:
-
Heat pump mode for heating: the unit produces hot water at the system side heat exchanger for heating.
- Heat pump mode for the production of domestic hot water: High temperature hot water is produced at the heat exchanger connected to the domestic hot water storage tank.
Automatic seasonal regulation
The system switches automatically between the various operating modes according to a priority logic for the production of domestic hot water.
