Decarbonisation and energy efficiency in a large, historic Roman hospital
Reducing consumption and emissions without disrupting existing systems: the solution is there.
A hospital in the capital, a centre of excellence for infectious diseases, has launched an energy requalification plan for its halls with a twofold objective: to reduce energy consumption and CO₂ emissions and to progressively eliminate the use of natural gas, while improving environmental comfort for staff and patients.
Thanks to the installation of the A-Therm80 heat pumps, Dethermina provided a modular, flexible and scalable solution, capable of handling both heating and hot water needs up to 80°C, as well as summer air-conditioning, ensuring maximum efficiency and continuity of operations.
The demand: energy efficiency and modularity without invasive intervention and service interruption
The hospital commissioned the company S.A.C.I.R S.p.A. and the design studio Futura Technologies S.r.l. to identify solutions to replace obsolete heat generators (methane boilers).
The requirement represented an opportunity to rethink the entire plant architecture with more efficient and sustainable technologies.
- Modularity and scalability, for gradual implementation without impacting hospital operations.
- Reduction of CO₂ emissions, to align with sustainability goals.
- Minimisation of operating costs, thanks to the use of a highly efficient system.
- Compatibility with existing facilities, without the need for invasive structural work.
- Continuity of service, to ensure maximum comfort for patients and staff.
The Dethermina solution: R290 high temperature heat pumps for green conversion
To meet the requirements of the project, Dethermina proposed the use of A-Therm80 high-temperature propane heat pumps for each hall.
The A-Therm80 high-temperature propane heat pumps are a modular system that can be integrated into existing systems without requiring heavy structural work.
A scalable, non-invasive solution to provide heating, cooling and hot water up to 80°C for each hall, without interrupting hospital operations.
The hospital complex energy efficiency project
The company S.A.C.I.R. S.p.A. of Rome oversaw the implementation, which began with the installation of two A-Therm80 units in the Scientific Management Pavilion, guaranteeing rapid execution and no invasive interventions.
The next phase envisages the extension of the system to the entire structure by 2025, allowing the hospital to reduce energy costs by progressively eliminating natural gas and reducing CO₂ production and emissions.
The intervention is integrated with a remote monitoring and management plan to optimise consumption.
Results and perspectives
Thanks to the A-Therm80 heat pumps, the clinical centre is realising a complete energy transition with concrete benefits:
- Reduction of CO₂ emissions and gradual but definitive abandonment of natural gas.
- Optimal thermal and acoustic comfort for patients and staff.
- High point and seasonal efficiency by implementing all the best technologies and solutions.
- Compliance with future environmental regulations, with a system designed to last over 20 years.
- Compliance with the stringent acoustic restrictions imposed by the surrounding environment.
The project sets a benchmark for energy efficiency in healthcare facilities, demonstrating how emissions can be reduced without compromising comfort and operational safety.
The best technologies at the service of comfort and the environment
- Environmentally friendly GAS R290 refrigerant with a GWP (Global Warming Potential) value of 3 and a zero ODP (Ozone Depletion Potential) value.
- Dedicated reciprocating compressors, with electric motor equipped with LSPM system and control with Inverter technology.
- Generously sized condensing coils based on proprietary design.
- Optimised refrigeration circuit, with integrated heat recovery system that allows free heat source in summer operation.
- High-performance, low-noise EC fans, directly coupled to the EC electric motor with permanent magnets and IP54 protection rating according to IEC 6052.
- PID with set-point regulation and control system, allowing precise power regulation in the partialisation phases, with precise control of operation, optimising operating capacity.
- LAN connection of the units, with the possibility of remote control.
- Compliance with future environmental regulations, with a system designed to last over 20 years.
- Respect of the stringent acoustic limitations imposed by the surrounding environment thanks to the acoustic insulation of the compressors and axial type fans directly coupled to the EC electric motor, an Axitop accessory installed at the outlet of the air flow from the fan, capable of reducing the sound power radiated outside.
Thanks to Dethermina’s solutions, the capital’s hospital will be able to eliminate its dependence on methane gas and reduce emissions in a short time, without invasive structural interventions and anticipating future needs, bringing innovation and sustainability to the healthcare sector, fully achieving the goal of Energy Transition.
