An air conditioning and heat pump tower includes a main casing, a plurality of connecting pipes, a compressor, a front heat exchanger, a rear heat exchanger, a fan unit, and an energy efficient arrangement. The energy efficient arrangement includes a first pre-heating heat exchanger supported in a front compartment of the main casing, and positioned between an outdoor air intake opening and an outdoor heat exchanging portion of the front heat exchanger. The air conditioning and heat pump tower may be operated between an air conditioning mode for absorbing heat from the indoor space, and a heat pump mode for producing heat to the indoor space. A predetermined amount of ambient air may be drawn through the outdoor air intake opening and may be pre-heated by the energy efficient arrangement before delivering to the indoor space.

An anti-tip bracket assembly for a window air conditioning unit is disclosed, and more particularly, an anti-tip bracket assembly that pertains to securing a window air conditioning unit within a window assembly while allowing a user to open and close the window assembly in a safe and convenient manner is disclosed.

An air conditioning unit and method of mounting the same in an opening in a wall, particularly an opening housing a window. The unit includes a front section disposed inside the building on a first side of the opening; and a rear section disposed outside the building on a second side of the opening. A duct extends between the front and rear sections and is clampingly engaged between the sill and a bottom end of the window. The duct includes a first duct member that moves cooled air in a first direction towards the inside of the building; and a second duct member that moves return air in a second direction away from the inside of the building. The duct is changeable in length to alter the distance between the front and rear sections so as to accommodate the air conditioning unit's installation in windows in different thickness walls.

An insulated cooler unit that produces cooled air is disclosed. The cooler unit includes, within a thermally-insulated housing chamber, an inlet for introducing air to be cooled, an outlet for exiting of cooled air, an air heat exchanger for cooling air, a first fan. The cooler unit additionally includes a first track member having a first channel member, at least one first sliding member configured to slide within the first channel member. The first fan is connected to the first sliding member and is slidably mounted in the first track member by the at least one first sliding member, and is capable of being slidably moved over a portion of a first length of the first track member.

A portable and reusable installation platform for easing the installation or maintenance of an air conditioner on a vertical wall includes at least one support base upon which at least part of the air conditioner is positioned during the installation or maintenance thereof. At least one connector extends from the first end of the support base and is configured to releasably engage the wall. At least one support leg extends downwardly from the support base and is configured to abut the wall to support the weight of the air conditioner placed upon the support base.

An auxiliary mounting device and a mounting and use method for a saddle window air conditioner. The auxiliary mounting device comprises a base and a bolt. The base is located below a connection section of a saddle window air conditioner, and forms a certain distance away from the connection section. One end of the bolt is connected to the base, and the other end of the bolt passes through the connection section and is threadedly connected to the connection section. During mounting, the bolt is first screwed into the connection section from top to bottom, the lower end of the bolt is connected to the base, and the upper end of the bolt is threadedly connected to the connection section; then the saddle window air conditioner and the auxiliary mounting device are together moved up to a window, and the base is located on the window; then the bolt is screwed out from the connection section from bottom to top, the bolt and the connection section move towards each other, and the connection section gradually moves towards the direction close to the base, thereby implementing slow descending of the saddle window air conditioner. The auxiliary mounting device features a simple structure and is easy to operate.

Disclosed is an auxiliary mounting device and a mounting method for a saddle-type window air conditioner. Two groups of mutually connected L-shaped main supports and L-shaped auxiliary supports are included. Main transverse supports are connected with auxiliary transverse supports, an upper surface formed after the main transverse supports are connected with the auxiliary transverse supports is a plane, and a connecting part of a saddle-type window air conditioner is located on the plane. The main transverse supports and the auxiliary transverse supports can move relative to each other, so that a distance between main vertical supports and auxiliary vertical supports is adjustable for adaptation to windows with different sizes, and that the applicability is strong. During mounting, the main transverse supports and the auxiliary transverse supports are located at an upper portion of a windowsill respectively, the main vertical supports are located on an outer side of a wall below the windowsill, and the auxiliary vertical supports are located on an inner side of the wall below the windowsill. Brackets are disposed on outer sides of the main vertical supports, clamping grooves are formed in a bottom plate of an outdoor part of the saddle-type window air conditioner, and the brackets are clamped in the clamping grooves, so that the saddle-type window air conditioner is more reliable and is unlikely to shake and tilt after mounted.

A single-package air conditioning appliance includes a housing defining an outdoor portion and an indoor portion. An outdoor heat exchanger assembly is disposed in the outdoor portion. The outdoor heat exchanger assembly includes an outdoor heat exchanger and an outdoor fan. An indoor heat exchanger assembly is disposed in the indoor portion. The indoor heat exchanger assembly includes an indoor heat exchanger and an indoor fan. A compressor is in fluid communication with the outdoor heat exchanger and the indoor heat exchanger to circulate a refrigerant between the outdoor heat exchanger and the indoor heat exchanger. The single-package air conditioner unit also includes a make-up air module. The make-up air module extends between the outdoor portion of the housing and an outside of the housing. The make-up air module includes a plurality of make-up air fans.
