As energy efficiency and sustainable development demand intensify, VRV 7 S The new generation of central air conditioning systems is developed to provide high performance, environmental friendliness, and flexible applicability to a wide range of structures. The systems are designed to be suitable for residential, store, office, and small to medium-sized commercial structures.
New developments with refrigerant R-32
VRV 7 S using refrigerant R-32An innovative cooling solution significantly reduces environmental impact. Compared to traditional refrigerant s such as R-22 or R-410A, R-32 has a higher thermal stability and better thermal stability GWP (Global Warming Potential) is significantly lower and does not cause ozone depletion (ODP = 0).
Due to its excellent heat exchange properties, the system VRV 7 S can reduce the amount refrigerant So, we're going to have to use this to get the system to work the environmental impact of the system can be reduced on average by about 76% compared to previous VRV S lines using R-410A.
Not only contributes to environmental protection, R-32 also helps to improve operational efficiency, optimize energy efficiency, and reduce operational costs for users.
Superior energy efficiency of VRV 7 S
VRV 7 S is comprehensively improved in both hardware and software to improve performance.
According to comparative data, this system reached:
- Cooling efficiency (EER) increases by an average of approximately 26% compared to VRV IV S
- Yield strength is approximately 14 – 17% higher than that of the VRV S series High Seasonal Efficiency
These improvements came from many new technologies, including:
Compressor swing inverter DC next generation
Each model VRV 7 S is fitted compressor swing inverter DC enhancements, with an integrated structure that reduces the number of moving parts. This has many benefits:
- Higher operating performance
- Lower Noise
- Reduced friction and leakage risk refrigerant
- Long device life and high reliability
VRT Smart II Intelligent Controller
System VRT Smart II temperature optimisation refrigerant based on the actual needs of each indoor unit. Through coordination of control between outdoor unit and indoor unit, the system can:
- Unnecessary Load Reduction
- Adjust the speed compressor and airflow precisely
- Improve energy efficiency
Compact design, flexible installation
One of the notable advantages of VRV 7 S is that compact outdoor unit design, which allows easy installation in confined spaces such as balconies or rooftops.
The system has power ranges from 4 HP to 9 HP, including model 7 New HPIt's giving us more options for projects.
Besides, the support system:
- Actual pipe length up to 120 m
- Maximum total pipe length 300 m
- Height difference outdoor unit – indoor unit up to 50 m
Thus, VRV 7 S can be readily adapted to a variety of building designs.
Sustainable operation in extreme climate conditions
VRV 7 S was designed to behave stably even in high-temperature environments.
The system may:
- Activity at Outdoor temperature up to 52°C
- Maintain rated cooling power even when outdoor temperature is reached 43°C
Technology PCB Coolant refrigerant It helps maintain the performance of electronic components even in high ambient temperatures, ensuring the durability and stability of the system.
Improve user comfort
VRV 7 S focuses not only on performance but also on user experience through its many utility features:
Dry Cool Operation – temperature and humidity control
Unlike the usual cooling mode, the Dry Cool Continue to control the humidity even after the room temperature has reached the set temperature, keeping the space cool and comfortable.
Night Quiet Mode – smooth night operation
Quiet operation mode reduces the noise of outdoor unit to minimum approximately 40 dB(A)It reduces the impact on the environment.
Optimal heating technology
Functions such as Defrost Learning and Defrost Before Stop It reduces the cooling time and increases heating time, improving the efficiency of cold - season operations.
Intelligent control and management systems
VRV 7 S platform support DIV-NETA high - speed communication system that connects system HVAC devices and manages operational data.
Also, the system can be integrated with a management platform MARUTTO E-Series, allow:
- Remote monitoring and control
- Analyze operation data
- Energy management
- Early error detection and maintenance support
This helps the building manager to optimize operating costs and improve system management efficiency.

Flexible air conditioning solutions for a wide variety of constructions
Owing to its flexible assembly and high performance, VRV 7 S is suitable for a variety of building types, including:
- High-end housing
- Restaurants
- Office
The system helps maintain a stable temperature, improves indoor air quality (IAQ) and provides a comfortable living and working environment.
✔ VRV 7 S We report a new step forward in central air conditioning technology, which combines high energy efficiency, environmental friendliness and intelligent control capabilities. With comprehensive improvements, this system not only meets the need for efficient cooling but also contributes towards the goal of sustainable development in the future.
