Ductless Heat Pump System
Space Efficiency: With fewer outdoor units required, multi-split systems minimize space occupancy, ideal for buildings with spatial constraints.
Low Maintenance: The modular design streamlines installation and upkeep, significantly lowering long-term maintenance expenses.
Durability: Engineered with advanced technology and premium components, the system guarantees extended service life and consistent, reliable performance.
Ductless Heat Pump System
Multi-split air conditioning systems (VRF/VRV systems) are highly efficient air conditioning systems widely used in commercial buildings, office buildings, hotels, and other locations. The following is a detailed introduction to VRV/VRF systems:
GRAD VRV/VRF system products range:
Outdoor unit cooling capacity: 8-126kw, single unit, can be multiple combined.
Ducted indoor unit cooling capacity:1.8-14kw
Cassette indoor unit cooling capacity: 2.8-16kw
Wall mounted indoor unit cooling capacity: 2.2-8kw
1. Working Principle
A multi-split system links one or more outdoor units to multiple indoor units, circulating refrigerant between them to enable independent control and adjustment. By dynamically regulating refrigerant flow based on indoor load variations, the system achieves exceptional energy efficiency.
2. Key Features
Energy Efficiency: Adapts refrigerant flow to actual demand, eliminating frequent start-stop cycles typical of conventional systems, thereby maximizing energy savings.
Installation Flexibility: Compatible with diverse indoor unit types (e.g., ceiling-mounted, wall-mounted, concealed units) to suit varying spatial requirements.
Zoned Control: Each indoor unit operates independently, allowing customized temperature and fan speed settings for personalized comfort.
Smart Functionality: Features intelligent controls for remote operation, scheduling, self-diagnosis, and seamless management.
Enhanced Comfort: Delivers quiet, stable performance with precise temperature regulation for optimal indoor environments.
3. Applications
Commercial Spaces: Offices, malls, convention centers—ideal for large-area, multi-room cooling/heating.
Hospitality Sector: Hotels benefit from individualized climate control to elevate guest comfort.
Residential Use: Perfect for spacious homes seeking efficient, eco-friendly solutions.
4. Future Outlook
As technology evolves, multi-split systems will advance further in energy conservation, sustainability, and smart integration, with a growing focus on user-centric design and intelligent management.
