[0018] Referring to FIGS. 2 and 3 for a first embodiment of the invention. The thin refrigeration air conditioner 2 has an air fan motor 3 on one side (a front side or rear side). Air passes through the thin refrigeration air conditioner 2 to perform heat exchange, then is discharged through one or more air outlet B11 located on a ceiling B into an A / C room A to meet A / C requirement. The thin refrigeration air conditioner 2 includes a casing 20 which houses a thin heat exchanger 21, an air intake chamber 22, an air exit chamber 23, a side chamber 24 and an air port baffle 25.
[0019] The thin heat exchanger 21 contains a piping assembly 211 which has a refrigerant input end 2111 and a refrigerant output end 2112. The piping height H of the thin heat exchanger 21 is much smaller than the longitudinal length D of the piping, thus is a thin structure (referring to FIGS. 2 and 4). It further has a water collection tray 26 and a water discharge tube 27 on a rear end of the bottom thereof....
Example
[0027] Refer to FIG. 5 for a second embodiment of the invention. The refrigeration air conditioner 4 has an air fan motor 3 on one side. The refrigeration air conditioner 4 includes a casing 40 which houses a thin heat exchanger 41, an air intake chamber 42, an air exit chamber 43, a side chamber 44 and an air port baffle 45. It differs from the first embodiment in that the air port baffle 45 is located on one side of the side chamber 44 and controlled by the controller 8 (referring to FIG. 9). The air port baffle 45 opens at a desired degree to control the amount of the first time air flowing out from the thin heat exchanger 41 and the second time air entering the side chamber 44. In this embodiment, the air exit chamber 43 further has a humidifier 46 with the required water supplied by a water collection tray 461 (or an external water supply). This embodiment is suitable in environments of low humidity, A / C, or freezer where adding moisture is needed.
Example
[0028] Refer to FIG. 6 for a third embodiment of the invention. The refrigeration air conditioner 5 has an air fan motor 3 on one side. The refrigeration air conditioner 5 includes a casing 50 which houses a thin heat exchanger 51, an air intake chamber 52, an air exit chamber 53, a side chamber 54 and an air port baffle 55. The side chamber 54 further has a return air branch port 56 on the bottom. And the air intake chamber 52 and the side chamber 54 are divided by a spacer 57 without communicating with each other. The air port baffle 55 is located in the side chamber 54 and controlled by the controller 8 (referring to FIG. 9). The air port baffle 45 opens at a desired degree to control the amount of the second time air flowing through the return air branch port 56. After the second time air has entered the air exit chamber 53 and mixed up with the first time air, the temperature difference between the delivered A / C air and the return air from the return air branch port 56 is maint...
