Beschreibung
Zusammenfassung:	A space conditioning system for conditioning air within an enclosed space. The system comprises a refrigeration subsystem configured to circulate a flammable refrigerant there-through. The refrigeration subsystem also comprises a safety module configured to include either: a leak-detector subunit, or, a start-up subunit. The leak-detector subunit is configured to monitor for a leak of the flammable refrigerant from the refrigeration subsystem, and, to generate an alarm signal if the leak is detected. The start-up subunit is configured to turn on one or more airflow devices configured to vent or mix a leaked flammable refrigerant.
