An outdoor unit includes a casing having a bottom panel formed in a rectangular shape in a planar view. The bottom panel includes a bottom portion constituting a lower face of the casing, and a rising portion rising from an outer peripheral edge of the bottom portion. A first holding part is provided to the rising portion on a side of one side face of the casing, and a second holding part is provided to the rising portion on a side of the other side face of the casing opposite to the side of the one side face.

A method for cleaning an air conditioner indoor unit and outdoor unit includes controlling a heat exchanger to enter a self-cleaning mode, adjusting an operating frequency of an air conditioner, an opening of a throttling device, and a corresponding fan speed of the heat exchanger, and maintaining an evaporating temperature of the heat exchanger within a present range to enable a frost process on a surface of the heat exchanger. When a differential pressure of the air conditioner meets a preset condition, a four-way valve changes a direction, switching defrosting to indoor and outdoor heat exchangers. When the differential pressure does not meet the preset condition, the air conditioner is adjusted to meet the preset condition and the four-way valve direction is changed to perform a defrosting switching to the indoor and outdoor heat exchangers.

A drainage tray for collecting condensate from a heat pump is disclosed, where the heat pump (3) being adapted to be mounted on a support (4) being mountable to at least one supporting structure to carry the weight of the heat pump (2) and the support (4) wherein the tray (2) comprises a peripheral and preferably inclined edge portion (7) defining a central recessed tray portion (8) configured to collect condensate, wherein the tray further comprises a condensate outlet (9) for removing the condensate from the tray (2).

An outdoor equipment support platform. The outdoor support platform includes an upper side that can support outdoor equipment thereon, such as an air conditioning unit. A plurality of channels are disposed on the upper side of the support platform that guide liquid away from the upper side of the platform to a support surface. The plurality of channels define a plurality of unrecessed portions. At least four of the plurality of unrecessed portions are located at a perimeter of the platform. At least one aperture is disposed on the upper side to receive a fastener therethrough.

A beam-receiving masonry unit bears an outdoor condenser component of a split air conditioning system. The masonry unit generally includes first and second faces each having at least one opening defined by one or more structurally supportive edges. The first face, the second face, and the space between them are sized to incorporate the unit into a block wall or foundation. The openings are positioned to receive a condenser support beam, and the structurally supportive edges in the faces bear the condenser support beam. The unit resists rotation of the beam after the unit is incorporated into a block wall or foundation. A fill opening allows cementitious fill to enter into the unit to bond the unit to a block wall or foundation.

According to one embodiment, an object of the present invention is to provide an outdoor unit of an air conditioner which is basically composed of small-size component parts and can have a large air-conditioning capacity by stacking the small-size component parts in a vertical direction in accordance with a required air-conditioning capacity.
