TM65ANZ Mid Level Calculation: R32 HYBRID INDOOR UNIT – EMBODIED CARBON
Brand: Mitsubishi Electric
Product Details
Product Name: PLFY-WL63VEM-E
Type: 4-way Cassette Indoor Unit
Designed for simultaneous heating and cooling with heat recovery, the R32 Hybrid system is a unique 2-Pipe Heat Recovery VRF System. It replaces refrigerant with water between the Hybrid Branch Circuit Controller and the indoor units. This Mitsubishi Electric technology offers the comfort and safety of a traditional hydronic system with the flexibility and control of modern VRF or VRV systems.
Calculation performed under TM65 ANZ local addendum by CIBSE.
Embodied Carbon Result
Total Embodied Carbon (Mid-level TM65 Calculation Method): 258 (kg CO2e)
The total embodied carbon footprint for the PLFY-WL63VEM-E unit, calculated using the mid-level TM65 methodology, is 258 kg CO2e. This figure represents the sum of carbon emissions across the product's life cycle, including materials, manufacturing, transport, use (with buffer for refrigerant leakage), and end-of-life stages.
