Description

[Detailed description of the invention] This invention relates to the improvement of water-cooled air conditioners installed on ships, etc., and its purpose is to make the installation and maintenance inspection of the air conditioners easier. be.

Conventionally, for example, in a small air conditioner for a ship, piping for flowing cooling water has been located on the back side of the air conditioner main body, and a water inlet, an outlet, and a drain port have been provided on the back. In other words, if they were installed at the front, the water supply and drainage pipes would be exposed inside the cabin, resulting in poor aesthetics, so they were unavoidably installed at the back. Therefore, when replacing or cleaning the double-pipe condenser, it becomes difficult to remove the double-pipe condenser, resulting in poor workability.

The present invention is intended to improve the drawbacks of the conventional water-cooled air conditioners mentioned above.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, A is an air conditioner mounted on a ship and equipped with a well-known water-cooled refrigeration cycle, 1 is a compressor, 2 is a double pipe condenser, and 3 is an evaporator. The air inside the cabin passes through the inlet 4a of the front grille 4, the air filter 5, and reaches the outlet air passage 7 by a blower disposed in the air passage 6. As is well known, this blower is composed of a motor 8, a fan 7, and a fan casing 10. The wind is then discharged from the air outlet 12 into the cabin through the wind direction deflection plate 11 from the air outlet 7. Double pipe condenser 2 that condenses refrigerant
is provided with flanges 14, 14 for connection with piping 13, 13 for flowing cooling water. The flanges 14, 14 are fixed with a holding fitting 16 provided on the substrate 15, and the cooling water pipes 13,
One end of 13 penetrates through hole 17 provided in substrate 15 and is connected to a water supply pump (not shown) or the like. Further, the other ends of the cooling water pipes 13, 13 are connected to the flanges 14, 14. Further, a drain flange 19 is fixed to the holding fitting 16 for connecting a drain water pipe 18, and the upper end of the drain flange 19 is connected to a water receiving tray 2 provided at the lower part of the evaporator 3.
0, and guides the drain water condensed in the evaporator 3 to the outside of the aircraft. The through holes 17 for the cooling water pipes 13, 13 are provided at the front of the air conditioner, and by removing the front panel 21, the cooling water pipes 13, 13 can be opened.
13 and the double pipe condenser 2, and its position is set so that the work of connecting and removing the double pipe condenser 2 can be performed. 22 is an electrical equipment storage box for operating the air conditioner, and 23 is a knob for operating the air conditioner. Reference numeral 24 denotes a soft lid made of synthetic resin or the like, which is removably attached to the through hole 17, through which the cooling water pipes 13, 13 and the drain water pipe 18 pass through.

Therefore, maintenance and inspection of the double pipe condenser 2,
Not only replacement work but also maintenance and inspection of electrical equipment can be performed by removing the front panel 21, which improves work efficiency. Also, cooling water pipe 1
3, 13 and the double-pipe condenser 2 can be connected and separated via the flanges 14, 14, making the work easy.

As is clear from the above embodiments, the water-cooled air conditioner of the present invention has the double-pipe condenser joint and water pipes closer to the front, making maintenance and inspection easier. Since the board penetration part is closed by the lid, it has various advantages such as preventing small animals such as mice or moisture from entering through the board penetration part, and also preventing corrosion of the air conditioner.
