System for refrigerant pressure relief in HVAC systems

A heating, ventilation, and air-conditioning system including an apparatus for reducing refrigerant pressure within the heating, ventilation, and air-conditioning system, the apparatus comprising:

• a receptacle;
• a manifold of a condenser of the heating, ventilation, and air-conditioning system, the manifold comprising a first plurality of leader tubes operable to receive a liquid refrigerant from a first pass of the condenser and a second plurality of leader tubes operable to direct the liquid refrigerant to a second pass of the condenser, the manifold being configured to provide a direct fluid connection between the first plurality of leader tubes and the second plurality of leader tubes such that, when the condenser is under a first pressure, the liquid refrigerant can pass from the first plurality of leader tubes to the second plurality of leader tubes without passing through the receptacle, the manifold having the liquid refrigerant accumulated therein below a saturation height of the manifold;
• and
• a relief tube comprising a first end fluidly coupled to the manifold at a location vertically below the saturation height of the liquid refrigerant within the manifold and a second end fluidly coupled to the receptacle at a location vertically above the saturation height of the liquid refrigerant within the manifold, the receptacle configured to receive refrigerant from the manifold responsive to a refrigerant pressure within the heating, ventilation, and air-conditioning system.
