Refrigerator appliance

A refrigerator comprising:

• a housing defining (i) a plurality of internal storage chambers and (ii) access openings, wherein each access opening provides access to one of the internal storage chambers;
• a plurality of doors, each door (i) disposed over one of the access openings and (ii) configured to transition between open and closed positions to respectively provide access to and cover one of the openings;
• an internal wall (i) disposed within the housing, (ii) separating a first of the internal storage chambers from a second of the internal storage chambers, and (iii) defining a channel that establishes fluid communication between the first and second of the internal storage chambers;
• and
• a pressure relief valve (i) secured to the housing, (ii) extending between the first of the internal storage chambers and an exterior of the cabinet, (iii) configured to automatically open to vent air from the first of the internal storage chambers to the exterior of the cabinet in response to air flowing from the second of the internal storage chambers to the first of the internal storage chambers via the channel while a first of the doors is in the closed position, and (iv) configured to remain closed in response to air flowing from the second of the internal storage chambers to the first of the internal storage chambers via the channel while the first of the doors is in the open position.

A refrigerator comprising:

• a cabinet defining first and second internal storage chambers;
• first and second doors (i) disposed over the first and second internal storage chambers, respectively, and (ii) configured to transition between open and closed positions to provide access to and cover the first and second internal storage chambers, respectively;
• a partition wall (i) separating the first internal storage chamber from the second internal storage chamber and (ii) defining a channel that establishes fluid communication between the first and second internal storage chambers;
• and
• a pressure relief valve (i) extending between the first internal storage chamber and an exterior of the cabinet, (ii) configured to open to vent air from the first internal storage chamber to the exterior of the cabinet in response to air flowing from the second internal storage chamber to the first internal storage chamber via the channel as a result of transitioning the second door to the closed position while the first door is in the closed position, and (iii) configured to remain closed in response to air flowing from the second internal storage chamber to the first internal storage chamber via the channel as a result of transitioning the second door to the closed position while the first door is in the open position.
