Abstract: A contoured A-coil heat exchanger is provided which enhances cooling capacity of the heat exchanger by increasing the volume rate of airflow therethrough. The two slabs of the A-coil each have discrete upper and lower sections, with the upper section of each slab having a greater number of rows of tubes than the lower section thereof, so that the lower section of each slab is narrower than the corresponding upper section. Therefore, the condensate collecting channel of a drain pan used with the heat exchanger can be made commensurately narrower because the channel need only be wide enough to accommodate the lower sections with fewer tube rows than the upper sections. The narrower channel allows the area of the drain pan central opening to be larger for a given size drain pan, thereby increasing the volume rate of airflow through the central opening and through the heat exchanger.

Abstract: The pressure within a compartment of a refrigerator is kept equalized with ambient atmospheric air to facilitate the opening of the refrigerator door. An air passage capable of communicating the compartment with ambient air is closed when the compartment pressure is equal to the ambient air pressure, and is automatically opened when the compartment pressure become less than the ambient air pressure. The opening of the air passage is under the control of water contained in a trap portion of defrost water drain conduit of the refrigerator. The level of that trapped water fluctuates in height in response to differences in pressure between the compartment and ambient air, and the change in that height is used to open (or close) the air passage. The trapped water itself can be used to block the air passage, or a closure member floating on the water can block the air passage.
