Abstract: A leak detection system of a heating, ventilating, and air conditioning (HVAC) system includes a sensor configured to detect a UV tracer in a monitored gas volume of the HVAC system. The leak detection system also includes a controller communicatively coupled to the sensor. The controller is configured to modify operation of the HVAC system in response to the sensor detecting the UV tracer in the monitored gas volume.

Abstract: A multiple-circuit heating and cooling system includes a first refrigeration circuit having a first condenser and a first evaporator and a second refrigeration circuit having a second condenser and a second evaporator. The first condenser and the second condenser are arranged in a first row split configuration, and the second condenser is downstream of the first condenser relative to a first air flow directed across the second condenser and the first condenser. Additionally, the first evaporator and the second evaporator are arranged in a second row split configuration, and the first evaporator is downstream of the second evaporator relative to a second air flow directed across the first evaporator and the second evaporator.

Abstract: A refrigerant leak management system for a heating, ventilating, and air conditioning (HVAC) system is disclosed. The system includes a controller communicatively coupled to one or more sensors disposed within the HVAC system. The controller measures a vibration pattern associated with a component of the HVAC system. The controller determines whether the vibration pattern is indicative of a refrigerant leak in the HVAC system. Additionally, the controller can modify operation of the HVAC system when the vibration pattern is indicative of the refrigerant leak in the HVAC system.
