Haier introduces its new R32 MRV7 S: an advanced VRF system integrating technology, safety, efficiency for modern solutions.

Haier HVAC Solutions Europe is pleased to introduce the new MRV7 S range, a cutting-edge VRF system engineered to meet the stringent requirements of the European F-Gas Regulation 573/2024. Utilizing the low-GWP R32 refrigerant (GWP = 675), the MRV7 S sets a new benchmark for comfort, safety, and energy efficiency. Through the integration of its most advanced climate technologies, Haier is revolutionizing how climate control solutions interact within modern environments. 

Specifically tailored for the European market, the MRV7 S system offers a powerful combination of high energy efficiency, innovative design, and a steadfast commitment to safety and environmental responsibility. This system not only enhances operational performance and simplifies installation procedures but also strengthens leak protection and significantly increases system flexibility. The MRV7 S is suitable for a diverse array of applications across vertical markets and is available in 4,5 & 6 HP single fan and 8,10 & 12HP double fan both with font discharge.  

Integrating design with efficiency

The introduction of the R32 MRV7 S emphasises Haier's dedication to transitioning its MRV range from R410A to R32. This innovative solution positions Haier at the forefront by boosting energy efficiency by up to 17%, implementing advanced safety features to prevent refrigerant leaks, and providing increased flexibility in installation, equipment control, and connectivity.

The MRV7 S incorporates a suite of innovative technologies to optimise efficiencies and operational costs. These include a Twin-rotary DC inverter compressor, which not only boosts efficiency but also reduces noise. A high efficiency stepless axial fan is engineered to move large volumes of air with minimal power consumption, contributing to sustainability through its robust design.  

The MRV7 S boasts a scalable and modular architecture, expertly designed to accommodate the specific needs of each individual project. It offers broad compatibility with a variety of indoor unit types, including wall-mounted, cassette, and ducted units, alongside extended pipe lengths up to 400 meters. This allows for highly adaptable configurations that seamlessly integrate with centralized control systems. From compact spaces to expansive infrastructures, the system guarantees customised comfort, without compromising on performance or efficiency. 

Integrating safety with precision

The MRV7 S is engineered with a multi-zone leak detection system, providing comprehensive safety through built-in leak detectors in all our indoor unit. The system incorporates visual and audible alarms within the new controllers. For added flexibility, an optional automatic shut-off valve can be installed, supported by a battery-powered emergency function, which is especially useful during power outages. This feature also allows for zone segregation, enabling the valve to isolate refrigerant and prevent leaks.

These advanced safety protocols are built-in to proactively manage and reduce risks throughout the product's lifecycle, from its initial design to its day-to-day operation, fully compliant with the new EU regulation 573/2024. 

Integrating installation and control flexibility

The MRV7 S is designed for streamlined installation and maintenance. It incorporates innovative features like Space-Link technology, a novel protocol that provides installers with unparalleled flexibility in wiring the communications network, moving away from the traditional chain method. This results in simplified wiring, faster installation times, and reduced cabling needs. Furthermore, the integrated Self-clean functions for both indoor and outdoor units not only ensure cleaner air quality but also minimize the accumulation of dirt and bacteria, thereby extending maintenance intervals.


To further enhance efficiency, the MRV7 S features automatic addressing functionality. This simplifies the commissioning process by automatically assigning unique addresses to each indoor unit, eliminating the need for manual configuration. This is particularly advantageous for larger VRF systems with numerous indoor units, making both installation and commissioning processes more efficient and user-friendly.

The new R32 MRV indoor units are all backward compatible with R410A refrigerant, reducing complexity from logistics to installation.

Our new controller has been given a communication protocol upgrade, with a smart interface which is compatible with both R32 and R410A indoor units. Integrated with faster communication and zero-latency operation. Furthermore, the system features AVRA-AI for intelligent refrigerant control and advanced communication protocols, allowing for faster installation and more precise system control. Each component is meticulously designed to provide practical, real-world solutions. 

Albert Sanchez - European MRV Product Manager commented :

"The new R32 MRV7 S is set to become an integral part of the Haier HVAC commercial portfolio, integrating intelligent technologies into a future-ready system that meets the needs of installers and future builds. It provides a safe, practical, and efficient solution for various projects and is highly competitive in the market. We look forward to sharing use cases in the near future".
