Hisense Mini 4-Way Cassette R32 / R410A Single Phase Indoor Unit FAQs
What is a 4-way cassette unit?
A 4-way cassette provides even air distribution in four directions, ensuring balanced comfort across larger spaces such as offices and shops.
What’s the difference between R410A and R32?
R410A has been widely used for years in HVAC systems, but it has a higher GWP compared to R32. Many new systems now transition to R32 for improved energy efficiency and to meet stricter environmental regulations.
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.
How do I choose the right VRF indoor unit?
The right indoor unit depends on room size, layout, and aesthetic preference. Options such as 4-way cassette units ensure even air distribution, while ducted units provide discreet airflow.
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.
