HVRF Indoor Units

Residential and commercial air conditioners are built to meet the specific needs of their intended spaces. This means they vary in construction since commercial spaces typically require more advanced technologies to suit their larger and more complex floor plans, increased occupancy and control requirements. Some key differences include:

• Capacity: Commercial applications often require higher capacity indoor units than residential systems can provide. City Multi indoor units are available in capacities up to 14 kW to accommodate larger spaces and higher cooling or heating loads..
• Control: Commercial air conditioning systems are designed for greater control integration with central control systems or a BMS.
• Components: Key components in commercial air conditioners are designed for longer, more continuous use. Residential air conditioners are designed for home use.

In healthcare facilities where comfort, safety and air quality are priorities, a reliable, efficient air conditioning system is essential. The City Multi Hybrid VRF system eliminates refrigerant from occupied spaces by using water between the HBC and indoor units, ensuring compliance with AS/NZS 5149 standards without requiring leak detection systems.

The water-based secondary circuit provides naturally stable temperatures throughout the year with milder off-coil temperatures, maintaining consistent comfort across different zones.

The selection of heat recovery models allows for operation that reduces energy consumption during simultaneous cooling and heating, compared to heat pump models, helping to lower operational costs for facilities requiring 24/7 climate control.

Yes. HVRF indoor units using heat recovery outdoor units deliver optimal energy efficiency thanks to simultaneous heating and cooling operations. The system reduces power consumption by recovering heat during operation, with energy savings increasing as simultaneous heating and cooling becomes more frequent.

VRF (Variable Refrigerant Flow) air conditioning uses refrigerant throughout the entire system. In VRF systems, refrigerant flows from the outdoor unit through a BC Controller to the indoor units.

HVRF (Hybrid Variable Refrigerant Flow) uses a dual-circuit approach: refrigerant circulates between the outdoor unit and the Hybrid Branch Controller (HBC), while water circulates between the HBC and indoor units. This hybrid design eliminates refrigerant from occupied spaces while maintaining the performance benefits of VRF technology.
