An air conditioning ventilation system comprising: air-intake portions 123 and exhaust portions 124 respectively provided in a plurality of rooms of a building; air-blowing sections 103 for sending wind to the air-intake portions 123; and a return zone 101 where air discharged from the exhaust portions 124 by the air-blowing sections 103 joins up; wherein the air-blowing sections 103 and an air conditioning section are placed in the return zone 101, a bathroom 106 and other rooms include ventilation intake portions 125 and ventilation exhaust section 126s to ventilate these room for exchanging air, the system includes a heat exchanging unit 111 which heat-exchanges confluence air of the plurality of rooms and the bathroom 106 and outside air, and discharges the air to outside of the rooms, and the outside air after the outside air exchanges heat with the confluence air is introduced into the return zone 101. The present invention provides the air conditioning ventilation system which prevents lifetime of the system from being shortened by dew condensation of a heat exchanging element while recovering heat during bath time, which prevents mold in the bathroom 106 by ventilation of the bathroom 106 for 24 hours, and which can always realize comfortable clean air living at all times by flow of air-conditioning air and flow of ventilation air in an entire house while saving energy.

An air conditioner indoor unit includes an air outlet frame, a front water receiving tray, and a panel. The air outlet frame includes an upper enclosure plate, a lower enclosure plate, and a side enclosure plate located between and connecting the upper enclosure plate and the lower enclosure plate. The front water receiving tray is above the upper enclosure plate and includes a protrusion section protruding out of the side enclosure plate and a water outlet hose at the protrusion section. The water outlet hose is configured to be received in a receiving cavity formed below the protrusion section and opening forward. The panel includes a cover member configured to cover the receiving cavity when the panel is in a closed state.

An inline drain sanitizing system, includes: a manifold assembly including an inlet port, an outlet port, and a treatment port, wherein: the inlet port is configured to be couplable to a condensate supply line and receive unsanitized condensate, and the outlet port is configured to be couplable to a condensate drain line and provide sanitized condensate; and a treatment subsystem configured to interface with the treatment port and process the unsanitized condensate to generate the sanitized condensate.

An apparatus includes a drain pan configured to receive liquid condensate from a horizontal evaporator coil above the drain pan and a drain pan extension coupled to the drain pan. A pin on the front and rear sides of the drain pan extension is fitted and movable within a corresponding notch in the front and rear sides of the drain pan. The drain pan extension is securably configurable in a first configuration and a second configuration. In the first configuration, the drain pan extension extends above the drain pan at a first angle relative to the drain pan. In the second configuration, at least a portion of the drain pan extension extends beyond the left pan side of the drain pan at a second angle, which may be selected for improved capture of liquid condensate from the horizontal evaporator coil.

A drainage system comprising a first bracket having a horizontal structure and one or more vertical structures, a second bracket having a horizontal structure and one or more vertical structures and a drain pan having a plurality of locking mechanisms, each configured to interlock with one of the vertical structures of the first bracket or the second bracket.

An air management device may include three independently operated primary impellers 131, 131′, 131″, and drawn-in air is discharged through discharge ports 15′-1, 15′-2, 15′-3 provided in the front plate 15 of the housing 10. Louvers 141, 142, 143installed downstream of the air flow and discharge ports 15′-1, 15′-2, 15′-3 may be independently opened or closed to provide discharge of the air to the surrounding environment. Further, at least one retractable or pop-up fan may be provided.
