VRF systems are “direct systems” that are installed in multi-tenant applications, such as hotels, dormitories, hospitals, office buildings, and apartment buildings. The high-volume design of VRF technology can pose a challenge to HVAC-R stakeholders.
If a refrigerant leak were to occur, all of the refrigerant charge could be directly released into a particular room. The risk-factor for occupied spaces is higher than other occupancy classifications. In fact, a large refrigerant leak into an occupied space can reach concentrations that pose an asphyxiation risk.
