Building owners, facility managers and the construction industry have been looking for HVAC systems that deliver high operational efficiency whilst minimising the Global Warming Potential of the refrigerants used within these systems.
Mitsubishi Electric’s R32 Hybrid VRF Systems provide a commercially viable alternative solution to traditional R410A systems and addresses one of the most pressing challenges in the New Zealand air conditioning industry on how to tackle high charge volumes and lower GWP refrigerants in large systems. It offers customers a future-proof solution that delivers advanced costs efficiencies with improved corporate social responsibility.
Water, rather than traditional refrigerant is at the heart of the indoor units. This means there is no risk of refrigerant leaking into small confined spaces. Hybrid VRF minimises the need for leak detection, reducing the total cost of the system and on-going maintenance of the leak detection system itself.
In commercial buildings, additional leak detection systems specific to air conditioning are often installed to safeguard occupants due to increasing safety regulations. This affects hotels in particular, where air conditioners are installed in the room space and occupant safety is critical.
A leak detection system is designed to trigger an alarm if refrigerant was to leak into the room space and shut down the system to try and prevent harm to the occupants. These systems can be expensive and add to the cost of design, build and maintenance.
Throughout a system’s lifetime, annual testing and the recalibration of leak detection sensors adds significant cost to a VRF system. Using Hybrid VRF instead, removes this need and could provide as much as 30% in maintenance savings over 15 years.
