MRV7 S

MRV7 S

The New R32 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. 

Additional Information

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 units. 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

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.

Automatic addressing functionality

Diamond Shield - R32 Safety Protection

  • Software: new version of the MRV selection software calculates the amount of refrigerant in the room and alerts if the safety limit is exceeded.
  • Alarm: the wired controller, panel and wall-mounted refrigerant detector can trigger a sound and light alarm in the case of a refrigerant leak.
  • Battery: SVP160A are equipped with a back-up battery, in order to supply power to close the shut off valves in the event of a system power failure.
  • Leak Detectors: Indoor units are equipped with built in leak detectors. There is no need to replace them after detection.
  • Recovery: In the case of a leakage, the system can recover the R32 refrigerant to the ODU and will be isolated by the shut off valves (single fan ODU). Unaffected units with SVP160A will continue operation, providing comfortable temperature to the user.
  • Shut off valve: the 4/5/6 HP MRV7 S outdoor units are equipped with built-in R32 shut off valves.
  • For the 8/10/12 HP MRV7 S outdoor units, an optional external shut off valve box (SVP160A) can be installed wherever it is necessary.

Haier Serene AI features

Serene enables you to experience the next evolution in smart air conditioning where cutting-edge engineering meets artificial intelligence for unmatched comfort and efficiency.

  • AI-Powered Eco Sensor : Serene features cutting-edge AI-powered sensor that detects air conditions, human presence and movements across the room and automatically adjusts the air conditioner's operating mode: by continuously adapting airflow direction, intensity and set temperature in real time, this system saves energy when the room is empty and delivers instant, personalized comfort the moment you return.

     

  • AI Safety Control : Serene leverages advanced artificial intelligence to respond to dangerous indoor conditions - it proactively prevents them. By continuously analyzing temperature, humidity trends, and environmental data, the system can anticipate potentially dangerous hot weather and automatically activate cooling to reduce both heat and moisture levels. This predictive approach ensures a safer, more stable indoorenvironment, especially for vulnerable individuals, while maintaining energy efficiency and minimizing unnecessary system usage.

 

  •  AI-Enhanced PID Control : Serene goes beyond basic heating and cooling by maintaining an optimal balance of temperature and humidity using advanced AI-driven PID control. Its high-precisionhumidity sensor works in real time with the AI system to regulate compressorfrequency, fan speed, and refrigeranttemperature with exceptional accuracy. This intelligent coordination minimizes energy consumption while maximizing comfort. The result is a stable, efficient indoor climate that supports both personal wellbeing and environmental sustainability.
