Passive House: Hybrid VRF for Passive House

An overview of design approaches with VRF equipment that is aimed towards reducing the amount of refrigerant in occupied spaces. We will review how Mitsubishi HEX coils can bring a building’s water loop infrastructure onto the VRF platform, as well as advancements in refrigerant-to-water products in the next generation of VRF equipment: Hybrid VRF – which eliminates refrigerant downstream of the branch circuit controller – and the upcoming QAHV – a domestic hot water heat pump system.
