Ventilation apparatus

A ventilation apparatus comprising:

• a housing including a first inlet configured to allow outdoor air to be introduced, a second inlet configured to allow indoor air to be introduced, a first outlet configured to discharge the air introduced via the first inlet into an indoor space, and a second outlet configured to discharge the air introduced via the second inlet into an outdoor space;
• a total heat exchanger disposed within the housing and configured to exchange heat between air flowing from the first inlet toward the first outlet and air flowing from the second inlet toward the second outlet;
• an evaporator configured to cool air flowing from the first inlet toward the first outlet;
• a condenser configured to heat air flowing from the evaporator toward the first outlet;
• and
• a drain pan disposed below the evaporator and the condenser,
• wherein the drain pan includes:
• a water collecting portion comprising a region of the drain pan defined by a rim configured to collect condensate water drained from a surface of the evaporator;
• and
• a cover rib protruding from the rim of the water collecting portion surrounding a bottom surface of the water collecting and configured to cover at least a portion of a side portion of the evaporator while facing a surface of the evaporator through which air flows into the evaporator.

A ventilation apparatus comprising:

• a housing including an inlet and an outlet;
• a total heat exchanger disposed between the inlet and the outlet and configured to exchange heat with air introduced into the housing through the inlet;
• a dehumidification module configured to remove water vapor from air flowing from the inlet toward the outlet, and
• a drain pan disposed below the dehumidification module,
• wherein the drain pan includes:
• a water collecting portion comprising a region of the drain pan configured to collect condensate water drained from the dehumidification module;
• and
• a cover rib protruding from a rim of the water collecting portion surrounding a bottom surface of the water collecting portion and configured to cover at least a portion of a side portion of the dehumidification module between the total heat exchanger and the dehumidification module.
