Coil with built-in segmented pan comprising primary and auxiliary drain pans and method

摘要

An air-conditioning system provides a segmented pan with a primary drain segment and a built in auxiliary drain pan segment to receive overflow condensate from the primary drain pan and drains through auxiliary drain lines. The built-in auxiliary drain pan and primary drain pan are plumb with respect to each other and are secured together and/or monolithic. The assembly construction thereby provides reduced time and costs associated with storing, transporting, installing, leveling, and plumbing individual components.

主权项

1. An air conditioning system which produces condensate, comprising:
an evaporator coil; a housing surrounding said evaporator coil, said housing defining an input for airflow; a segmented pan, a first segment of said segmented pan comprising a primary drain pan positioned to receive said condensate from said evaporator coil, and a second segment of said segmented pan comprising an auxiliary drain pan; a primary drain outlet positioned in said primary drain pan to drain said primary pan; an auxiliary drain outlet positioned in said auxiliary drain pan to drain condensate from said auxiliary drain pan; an overflow wall that separates said primary drain pan from said auxiliary drain pan to prevent any condensate flow into said auxiliary pan until an overflow level of condensate is reached in said primary drain pan, said overflow wall being configured to then permit condensate to flow past said overflow wall into said auxiliary drain pan for draining through said auxiliary drain outlet, whereby said overflow level and said overflow wall each comprise a height at least above said primary drain outlet.
