Hisense All Fresh Air Single Phase Indoor Unit FAQs
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’s the difference between an indoor and outdoor unit?
Outdoor units house the compressor and release or absorb heat, while indoor units distribute conditioned air into the building. Together, they form a complete HVAC system.
        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.
