A packaged terminal air conditioner (PTAC) system includes a wall sleeve in which a chassis is mounted. The wall sleeve includes a bottom configured as a drain pan to collect condensate from the chilling components of the chassis. The floor of the drain pan includes a reservoir that extends downward from the floor. The floor slopes downward from the sides of the bottom to the reservoir so that water falling onto the floor flows toward and into the reservoir where it is retained until the height of the water in the reservoir exceed a rim around the drain opening. The rim further prevents treatment pellets from falling into the drain so that they can dissolve in the water captured by the reservoir until the water level of the reservoir flushes the treated water into the drain.

A water receiving tray for a window air conditioner includes a tray body and a wiring body. The tray body includes a water tank. The wiring body is provided at a side of the tray body proximal to an outdoor part of the window air conditioner. The wiring body includes a wiring groove.

An air conditioner installable on a window frame and having a ventilation function. The air conditioner comprises a cabinet comprising a first inlet hole, a second inlet hole and a third inlet hole, a first heat exchanger provided inside the cabinet to allow indoor air, which is introduced through the first inlet hole, to exchange heat, a second heat exchanger provided inside the cabinet to allow outdoor air, which is introduced through the second inlet hole, to exchange heat, and a third heat exchanger provided inside the cabinet to be located between the first heat exchanger and the second heat exchanger in a height direction of the cabinet, and provided to allow outdoor air, which is introduced through the third inlet hole, and condensed water, which is generated in the first heat exchanger, to exchange heat with each other.

Disclosed is the window unit of indoor air conditioning device. The disclosed device is split into two sections, with one being inside a room and the other hanging outside of the exterior wall. The two sections are connected together via a conduit channel, which is also used as a low-profile conduit, using flexible piping. The flexible piping are breakingly coupled within the conduit using snap connectors or twist-off connectors. The conduit being placed over a windowsill, wherein the windowsill supporting the weight of both containers.

A window air conditioner includes a casing including an indoor portion and an outdoor portion, an indoor fan wheel arranged in the indoor portion, and an indoor heat exchanger arranged in the indoor portion. The indoor portion includes an air inlet and an air outlet. The indoor heat exchanger includes a first heat exchange portion extending vertically and a second heat exchange portion connected to the first heat exchange portion and extending obliquely towards the indoor fan wheel.

Described herein is a heating/cooling window unit designed to be compact and reversible in operation to provide both heated and cooled air to an indoor room. The heating/cooling device is equipped with a touch control panel, a heat pump, and a set of cooling and circulating fans.

A water receiving tray for a window air conditioner includes a tray body and a wiring body. The tray body includes a water tank. The wiring body is provided at a side of the tray body proximal to an outdoor part of the window air conditioner. The wiring body includes a wiring groove.

Modular element adapted to replace a portion of the façade of a building in correspondence with at least one floor of the building, comprising an air conditioning unit and a channeling system, wherein the channeling system is configured to receive a fluid from an external fluid source, and comprises at least one first channel entering the air conditioning unit, and wherein the air conditioning unit comprises: a mechanical ventilation element configured to generate an air inflow into the building and an air outflow from the building, and to exchange heat therebetween; a hot and/or cold air diffusion element configured to heat and/or cool the air inflow using the circulating fluid in the first channel and to introduce the air inflow inside the building; an electronic control element configured to control the hot and/or cold air diffusion element and the mechanical ventilation element.
