Close Up View of the Main Ventilation System Filter and Conditioning Compartment.
Click on this photo to get the largest view. Notice the two round gauges on violet water pipes. The round gauge at right is the inlet water pressure. The round gauge at left is the outlet water pressure. The long thin gauge between the two violet pipes shows the water temperature. As explained earlier, the water in the violet pipes is chilled in summer and heated in winter. This water enters heat exchangers in this filter compartment and thus pre-warms the incoming fresh air in winter, and pre-chills the incoming fresh air in summer. The summertime chilled coils in this compartment, on purpose, are cold enough to condense excessive South Carolina muggy-muggy moisture from the incoming fresh air. Condensate water collects in the bottom of the compartment and goes to a floor drain by means of a copper pipe. The copper pipe is seen running from the U-trap at the right front corner of the compartment to the hole in the floor at center front of the compartment.
