Abstract
An air conditioning system is provided and includes a unit receptive of refrigerant having a moderate-to-low global warming potential (GWP) value for thermal interaction with a fluid, an enclosure, a fan disposed and configured for urging a flow of the fluid through the unit, a refrigerant detection sensor and a controller. The refrigerant detection sensor is disposed in the enclosure to be operable in a first mode in which a baseline response is established and a second mode in which refrigerant leak detection is executed based on the baseline response. The refrigerant detection sensor is further configured to generate a binary output of leak and non-leak signals in accordance with a result of the refrigerant leak detection. The controller is configured to control operations of the fan and the vent based on the binary output.
