Hitachi Light Commercial R32 Mini Cassette Indoor Unit FAQs

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 R32 refrigerant and why is it used in HVAC systems?
R32 is a next-generation refrigerant with lower global warming potential (GWP) than older gases such as R410A. It delivers high efficiency while helping reduce environmental impact, making it a popular choice for modern heat pumps and air conditioning units in the UK.
Are HVAC systems noisy?
Modern indoor units are designed for quiet operation, with sound levels often comparable to a whisper, making them suitable for bedrooms and offices.
Can HVAC systems provide both heating and cooling?
Yes. Heat pump-based systems can reverse their operation to provide heating in winter and cooling in summer, offering year-round comfort.
How energy efficient are modern air conditioning and heat pump systems?
Modern HVAC systems achieve high seasonal efficiency ratings - SEER (Seasonal Energy Efficiency Ratio) and SCOP (Seasonal Coefficient of Performance), lowering running costs compared to older units while reducing carbon emissions.
Can HVAC systems help improve air quality?
Yes. Many units include advanced filtration that removes dust, allergens, and pollutants, contributing to a healthier indoor environment.
