Abstract
Abstract An air-conditioning apparatus, of the room air-conditioning type which can be easily installed at any desired location in a room, as in a window therein, comprising a cabinet structure, a cabinet insulation structure and a partition board dividing the interior of the cabinet into an interior compartment and an exterior compartment. The insulation structure consists of right side, left side, top and bottom insulation boards. The insulation structure and the partition board are all made of plastic insulation material, such as polystyrene resin foam. Each insulation board has a plurality of projections and grooves corresponding with each other and with portions of the refrigeration components, such as the condenser and the evaporator, so that these components are fixedly interposed therebetween, when assembled.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
157 words
An air conditioning apparatus comprising: a cabinet structure consisting of bottom, right side, left side, top, front and rear walls; a refrigeration system arranged in said cabinet structure; an insulation structure made of foamed plastic insulating material consisting of bottom, right side, left side and top insulation boards for thermally insulating said cabinet structure, each of which is in a closely mating relationship with said corresponding wall and each having catch means therewith for interconnecting adjoining insulation boards together and for fixedly disposing therebetween components of said refrigeration system, when assembled; and a partition member made of the same material as that of said insulating structure, with its bottom, right, left and top sides firmly and fixedly positioned by said catch means of said insulating structure for dividing the cabinet interior into an interior compartment, including an interior fan case housing an interior fan, and an exterior compartment, including an exterior fan case housing an exterior fan.
