Provided is an air conditioner. The air conditioner comprising a housing having an inlet and an outlet, a fan in the housing to suck in air through the inlet and discharge air through the outlet, and including a plurality of fan blades with an installation space between two fan blades of the plurality of fan blades, a fan driver coupled to an end of the fan by a fastener, to drive the fan, wherein the installation space is positioned to allow the fastener to pass through the installation space to couple the fan driver to the fan, and a stabilizer including a body having at least a portion extending along the fan at a first distance from the fan, and so as to not be over the installation space as the fan rotates, and a modifier extending along the fan at a second distance, which is greater than the first distance, from the fan, and so as to be over the installation space for at least part of a full rotation of the fan as the fan rotates.

An evaporative cooler which includes a sealed loop of conduit with a first portion in a space to be cooled and a second portion in a space where heat is rejected, a volume of working fluid, and a fan inside the conduit loop. The fan forces air over the working fluid to accelerate its evaporation, which requires heat. Evaporation creates vapor-enriched air which carries heat and is forced by the fan to the second portion. Within the second portion, the vapor-enriched air rejects the absorbed heat before being forced back to the first portion. In certain cases, a portion of the working fluid in the vapor-enriched air condenses out and drains or is pumped back to the first portion. In certain uses, the cooler provides cooling to an area. In other uses, the cooler captures vaporized water, producing an impurity-free condensate for removal or use.

A heat exchanger core for a heat pump, comprising a first chamber comprising a chamber body, the chamber body comprising an air inlet, an air outlet and a first heat exchange coil adjacent to the air inlet and inclined with respect to the air inlet; a second chamber comprising a chamber body, the chamber body having an air inlet, an air outlet and a second heat exchange coil adjacent the air inlet and inclined with respect to the air inlet; the first heat exchange coil and the second heat exchange coil forming a circuit for circulating refrigerant between the first heat exchange coil and the second heat exchange coil.

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.

Disclosed is a window air conditioner drain that includes a main body having a drain side and an interfacing side. The drain side includes a funnel structure that narrows to a tube attachment portion of the funnel structure. The window drain further includes a magnetic attachment mechanism configured for magnetically attaching the main body to a window air conditioner such that the main body covers a drainage hole of the window air conditioner. Further disclosed is a window air conditioner drain kit incorporating the window air conditioner drain, and a kit that includes the window air conditioner drain, magnets and/or a flexible tube.

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.
