Hitachi Light Commercial R32 Heat Pump Outdoor Unit FAQs
What is a heat pump?
A heat pump transfers heat rather than generating it through combustion, offering efficient heating and cooling. Modern heat pumps can deliver multiple units of heating for every unit of electricity consumed, helping lower running costs.
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 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.
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.
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.
