Hitachi IVX Centrifugal R410A 3 Phase Fan Heat Pump Indoor Concealed Condensing Unit FAQs
What does inverter technology mean in HVAC?
Inverter systems adjust compressor speed to match demand, reducing energy use and maintaining a stable temperature more efficiently than fixed-speed units.
What’s the difference between single-phase and three-phase HVAC systems?
Single-phase systems are common in UK homes and small businesses, while three-phase systems are designed for larger commercial or industrial applications where higher power and efficiency are required.
What is a VRF system?
VRF (Variable Refrigerant Flow) systems allow multiple indoor units to be connected to a single outdoor unit, with each zone individually controlled. This makes them highly efficient and flexible for commercial and large residential projects.
What are the main benefits of VRF?
VRF offers energy efficiency, individual room control, quiet operation, and the ability to provide simultaneous heating and cooling across different zones.
Are VRF systems suitable for UK buildings?
Yes, VRF is widely used in UK offices, retail, hospitality, and multi-residential buildings thanks to its efficiency, modular design, and compatibility with varying climate conditions.
