Hitachi Shirokuma R32 Heat Pump Outdoor Unit FAQs
What is Hitachi Shirokuma?
The Shirokuma range includes premium indoor wall-mounted residential air conditioning units that pair with powerful outdoor heat pump units. The range combines sleek design, energy efficiency, and advanced features.
Is Hitachi Shirokuma quiet?
Yes, the Shirokuma series is designed for ultra-quiet operation, making it ideal for bedrooms and living spaces.
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.
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.
What size HVAC unit do I need?
Sizing depends on room dimensions, insulation, occupancy, and usage. Oversized or undersized systems waste energy and reduce comfort - a qualified installer should calculate the correct capacity. Contact us at The MEP Shop today and we can help you size up your project correctly.
