Description

[Detailed description of the invention] This invention relates to an improvement of an integrated air conditioner that houses a refrigeration cycle in a single box, which has high efficiency, low noise, and low vibration, and facilitates condensed water treatment. It is something.

Conventional integrated air conditioners use a so-called vertical rotary compressor having an elongated cylindrical shape as a compressor, and the vertical rotary compressor is disposed in an outdoor ventilation system. In this case, the outdoor blower
Air sucked in from the outdoor side passes through a vertical rotary compressor, passes through an outdoor heat exchanger, and is discharged outdoors. At this time, heat is carried away from the surface of the compressor's outer shell, which is at a high temperature, by the passing wind. At this time, the heat transfer between the compressor outer shell and the air is caused by Since it is heat transfer, the amount of heat transferred is extremely small. Therefore, the refrigerant sucked into the compressor passes through the main body, which has not been sufficiently cooled, and is therefore reheated, increasing the specific volume and reducing the efficiency of the compressor.

The present invention eliminates the above-mentioned drawbacks by locating a compressor in condensed water and sprinkling the condensed water with an outdoor fan. The present invention will be described below with reference to FIGS. 1 and 2 of the accompanying drawings showing one embodiment thereof.

The integrated air conditioner 1 includes a substrate 2 having a depth h.
The main body is composed of a partition wall 3 provided on a substrate 2 to separate an indoor ventilation system path I and an outdoor ventilation system path O, an outer box 4, and the like. The outdoor ventilation system path o includes an outdoor heat exchanger 7 mounted facing the air outlet 6 on the back surface 5, a motor 8 mounted with its rotating shaft perpendicular to the partition wall 3, and a A flange-like webbed tool attached to one end of the shaft for blowing wind toward the outdoor heat exchanger 7, scooping up condensed water in the substrate 2, and spraying this water onto the outdoor heat exchanger 7. (hereinafter referred to as a slinger ring) 9, the outer ring 11 is located within the depth h of the substrate 2, and the air guider 19 of the axial fan 10 is located so as to pass through it. A stationary high pressure type rotary compressor 12 is installed. Further, the indoor ventilation system path I includes an indoor heat exchanger 15 installed facing the suction port 14 of the front surface 13, and an indoor heat exchanger 15 installed on the other end of the shaft of the motor 8 and passing through the indoor heat exchanger 15. A multi-blade fan 17 or the like is provided to blow out the wind into the wind tunnel section 16. Further, the partition wall 3 on the substrate 2 is provided with a communication pipe 18 connecting the indoor ventilation system path I and the outdoor ventilation system path O at the lower end of the partition wall. Reference numerals 20 and 21 are suction ports formed on the left and right side surfaces of the box body 4, which communicate with the outdoor ventilation system path o.

The operation in the above configuration will be explained. The refrigerant discharged from the horizontal high-pressure rotary compressor 12 is cooled in the outdoor heat exchanger 7 by air blowing from the axial fan 10, reduced in pressure by a throttle device (not shown), and then transferred to the indoor heat exchanger 15. It is evaporated by the ventilation of the multi-blade fan 17 and returns to the compressor 12 again, forming a well-known refrigeration cycle. At this time, multi-wing fan 1
At step 7, the air sucked from the indoor side and passed through the indoor heat exchanger 15 for heat exchange is deprived of moisture and is discharged indoors again as shown by the arrow in FIG. It accumulates on the side of the inside ventilation system path I, and eventually penetrates into the outside side of the board 2 through the communication pipe 18 attached to the partition wall 3.

On the other hand, in the outdoor side ventilation system path o, the air sucked from the outdoor side by the axial fan 10 through the suction ports 20 and 21 passes through the outdoor side ventilation system path o where the compressor 12 and motor 8 are located, and passes through the air guider 19. The air then reaches the outdoor heat exchanger 7 and is discharged from the outlet 6.
At this time, the compressor 12, which is of a high-pressure type and has a fairly high external temperature, is exposed to this wind flow, and heat is removed from the surface by the air. Also, as mentioned above, when condensed water accumulates on the substrate 2,
The compressor 12 is arranged such that the outer shell 11 overlaps within the depth h of the substrate 2.
1 is immersed in water, it is also cooled by cold condensed water, and at the same time, the water stirred up by the rotation of the slinger ring 9 of the axial flow fan 10 is
Compressor 1 arranged through air guider 19
2, resulting in more powerful cooling.

In this way, the compressor 12 is effectively cooled by both air and water, so that reheating of the refrigerant returning to the compressor 12, especially in the horizontal high-pressure rotary type compressor 12, is reduced and efficiency is increased.

In addition, horizontal high pressure type rotary compressor 1
Since the compressor 2 is connected to condensed water, the vibration and noise generated by the compressor 12 itself is transmitted to the water, which also has the effect of reducing the level of vibration and noise generated from the integrated air conditioner 1.

Also, since the compressor 12 is exposed to condensed water,
When the water temperature increases significantly and the axial flow fan 10 rotates,
When the water scraped up by the slinger ring 9 hits the outdoor heat exchanger 7, it may easily evaporate.

In addition, horizontal high pressure type rotary compressor 1
If it is 2, the position is about half inside the board 2, so the ventilation resistance in the outdoor ventilation system path is lower than that of a conventional vertical rotary compressor, which increases the air volume and reduces noise. The decline can be measured. In addition,
The above-mentioned compressor 12 is particularly effective if it is a horizontal high-pressure type rotary type, but is not limited thereto.

In this way, the present invention locates the compressor in the condensed water stored on the board, and also sprinkles condensed water onto the compressor using a webbed device installed on the outdoor blower, which reduces ventilation and the sprayed water and water. Cooling is achieved from both the soaked water and the efficiency of the compressor is greatly improved. In other words, since the compressor is installed in the outdoor ventilation system, even if there is not enough condensed water at the beginning of compressor operation, the compressor can be cooled down, and the compressor operation time becomes longer, causing the compressor temperature to drop. When the temperature rises, the amount of condensed water increases, which increases the amount of water sprayed on the compressor, increasing the cooling effect.Furthermore, the blower normally stops after the compressor stops, but the condensed water In addition to being cooled, underwater noise and vibration are also reduced.
Furthermore, natural evaporation can be promoted by increasing the temperature of the condensed water.

Furthermore, since the compressor is horizontally mounted, a large submerged volume can be obtained even when the water level of the condensed water is low, and the condensed water used for cooling the compressor is stirred by the action of a slinger ring. Because of this, the water temperature can be kept low and the cooling efficiency of the compressor is also high.
