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, minimises this need and could provide as much as 30% in maintenance savings over 15 years.
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.
The 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 in the room. These systems can be expensive and add to the cost of design, build and maintenance.
Hybrid VRF minimises the need for leak detection in each room because there is no refrigerant piped into the room space, just water! This means there is minimal risk of refrigerant escaping into the room space. The Water-Based Fan Coil Units also reduce draughts; improving comfort for guests whilst providing overall savings in ongoing maintenance costs of the equipment for the hotelier.
