Aermec PRG: the new generation of reversible heat pumps with R290 refrigerant
Aermec's new PRG series of reversible heat pumps uses the natural refrigerant R290 to ensure high energy efficiency and a reduced environmental impact.
The air conditioning sector is undergoing a profound technological evolution, driven by the growing need to improve energy efficiency and reduce emissions from systems. In this context, Aermec offers the PRG series, a range of reversible heat pumps designed to offer high performance and greater sustainability thanks to the use of the natural refrigerant R290.
This new line was developed for residential, commercial, and industrial applications, with a particular focus on reducing emissions and optimizing energy consumption. R290 refrigerant , with a GWP (Global Warming Potential) of 3 , represents a strategic solution for those seeking an environmentally friendly system without compromising the system's operating efficiency.
Advanced technology to improve energy efficiency
PRG heat pumps stand out for their design architecture that integrates a double refrigerant circuit , a solution that significantly reduces the amount of refrigerant used. Each circuit contains 3.8 kg of R290 , a significantly lower amount than traditional standards, allowing compliance with the requirements of the EN 378-1 regulation and ensuring safe system management.
The use of optimized scroll compressors , available in tandem configuration, helps improve the overall efficiency of the machine. This design choice, combined with the presence of regenerative exchangers , allows for high seasonal efficiency, reducing energy consumption and improving performance in all operating conditions.
The PRG series is also characterised by a wide range of power ratings, between 50 kW and 145 kW , which allows it to meet the needs of systems with different levels of complexity and size.
Reliable performance even in extreme weather conditions
One of the distinguishing features of the new Aermec range is its ability to maintain high performance even in particularly harsh climate conditions. The PRG series is designed to operate at full load with outside temperatures as low as -20°C, ensuring operational continuity even in the harshest winter months.
During the summer season, the system is able to work with external temperatures of up to 48°C, ensuring thermal comfort is maintained even in the most critical conditions.
Furthermore, these heat pumps can produce hot water up to 75°C , a feature that makes them particularly suitable for both industrial applications and buildings with high heating needs.
Integration with hydronic systems and advanced security systems
The PRG series is designed to work in conjunction with hydronic systems, adapting to various system configurations and multiple application needs. The reduced refrigerant content per refrigeration circuit, less than 5 kg, facilitates both installation and system management, while ensuring compliance with safety regulations.
To ensure reliable operation over time, Aermec has equipped these heat pumps with numerous advanced safety systems . Among these, the electronic valve allows for precise control of refrigerant flow, while the internal leak detector monitors any leaks, preventing malfunctions and helping to maintain high safety standards.
The system also integrates double safety valves with exchange tap , useful for optimal management of internal pressures, and robust protection grilles , designed to protect the components from external agents and increase the overall durability of the unit.
Aermec PRG: high performance and attention to sustainability
With the PRG series, Aermec introduces a technologically advanced solution to the air conditioning landscape, capable of combining energy efficiency, operational reliability and environmental sustainability.
The use of the natural refrigerant R290 allows for a significant reduction in the system's environmental impact, complying with increasingly stringent European regulations regarding the reduction of greenhouse gas emissions.
Thanks to its application versatility and reliable performance, the PRG series represents an attractive choice for designers and installers seeking an efficient, safe reversible heat pump that complies with the latest regulatory standards. Aermec's commitment to research and development translates into a cutting-edge technological solution, designed to ensure high performance year-round and in a variety of application contexts.
