ABSTRACT:
The present invention relates to a window-type of integrated air-conditioner, specifically, to a window-type of air-conditioner for fulfilling the object of high efficiency and low noise through the improvement of its evaporator and condensers.
At present, there are many kinds of air-conditioners, but generally they are divided into two main kinds—window-type of air-conditioners and split-type of air-conditioners. In the window-type of air-conditioner, the vertical plate-type design is usually used for the evaporator, and a centrifugal fan is used, and the wind-blowing-type arrangement is generally used for its condenser and the vertical plate-type design is also used. Though this structure can fulfill the object of adjusting the air in a room, because the dimensions of the plates of the prior window-type air-conditioner facing the inside and outside of the room are limited, the heat-exchanging dimensions of the above evaporator and condensers are limited to some extent, in order that the heat-exchanging results of the evaporator and condensers fulfill the requirements for design, usually it is fulfilled by increasing the rotating speed of the fan, but the increase of the rotating speed causes the increase of the noise. Therefore usually the deficiencies of lower heat-exchanging efficiency, relatively more noise, poor-distribution of heat exchange, and lower energy-to-efficiency ratio, etc. exist in the present window-type air-conditioner.
An object of the present invention is to provide a window-type integrated air-conditioner for effectively improving the heat-exchanging results of the evaporator by means of a multi-section-type evaporator arranged according to a folded form and improve the heat-exchanging efficiency of the condensers by means of multiple sets of wind-inhaling-type condensers to make it have the advantages of higher heat-exchanging efficiency, low noise, well-distribution of heat exchange and marked increase of energy-to-efficiency ratio, etc. so as to effectively overcome the deficiencies of the prior art.
The object of the present invention is fulfilled through the following mode: a window-type of integrated air-conditioner mainly comprises a compressor, a cross-flow fan, an evaporator, a worm casing, a worm tongue, an outer housing, a face housing, a wind inlet, a wind outlet, condensers and an axial blow fan, characterized in that the assembly of evaporator is composed of several sections of the evaporator connected from the beginning to the end and is arranged in a folded form.
