Description

[Detailed description of the invention] This invention relates to the improvement of an air conditioner equipped with a compressor and a water-cooled condenser. This invention relates to an air conditioner with improved condensing capacity of a condenser.

An embodiment of the present invention will be described below with reference to the drawings.

The one shown in Fig. 1 is a packaged floor-standing air conditioner with a water-cooled condenser.An air outlet 2 is formed on the top surface of the main body 1, an air suction port 3 is formed on the bottom surface, and the inside of the main body 1 has a vertical partition plate. 4 and 5, three units A on the left and right.

It is divided into chambers B and C, and the central chamber B has two upper and lower wheels B1. It is divided into B2.

In the central upper chamber B1, an evaporator 7 and a hot water coil 8, which is connected via piping to a water heater (not shown) installed outdoors, are arranged in close proximity, and in the lower chamber B1, a multi-blade fan 9 and a fan casing are installed. A sirocco type blower 11 consisting of 10 and a motor 12 for driving the fan 9 are fixed to the partition plate 6.

Further, in the left chamber A, there is a compressor stand/dew tray 1 supported and fixed by a support frame 14 fixed to the bottom plate 13 and the partition plate 4.
A compressor 16 is supported above the compressor 5 in a vibration-proof manner, and a water-cooled condenser 17 is disposed below the compressor 16.

Since the compressor 16 is located above, it can be easily removed by removing the removable top plate 18 and front plate (not shown).
)? The compressor 16 can be inspected and repaired regardless of the details 17 and 17, improving serviceability.

Further, the suction pipe 19, which has one end connected to the evaporator 7 and the other end connected to the compressor suction port, is provided with U-shaped suction traps 19 a and 19 b.
a, 19b are provided, and this trap 19a.

19b is positioned above the dew pan 15, and the drain hole 15a of the dew pan 15 is provided relative to the pipe 20 of the water-cooled condenser 17, as shown in FIG.

The pipes 20 include an inner pipe 20a through which cooling water flows and an inner pipe 20a.
The dew adhering to the suction pipe 19 flows toward the traps 19a and 19b and drips from the lower ends of the traps 19a and 19b into the dew pan 15. The water is collected and drained from the drain hole 15a to the pipe 17.
It is sprinkled on the water and contributes to improving the condensation ability.

Furthermore, vibrations of the compressor 16 are absorbed by the formation of the suction trap.

The water-cooled condenser 17 also has piping connection ports 21 on the left and right sides.
A water pipe 21.22 having a, 21b, 22a, 22b is connected.

On the other hand, the drain pipe 2 connected to the drain port 6a of the partition plate 6
3 also has piping connection ports 23a, 23b on the left and right, and these right side outlet ports 21a, 22a, 23a are provided facing into the chamber C on the right side, and in this chamber, the pipes are connected in three directions: right, bottom, and rear. External piping can be selectively connected to the left side connection ports 21 a , 22 b , and 23 b are exposed outside the machine.

Note that the connection port on the side that is not used is blind plugged.

As shown in Fig. 3, the water pipes 21, 22 and the drain pipe 23 are arranged on a bottom plate 13 in which a suction port 3 is formed and the periphery is raised to form a dish shape to increase strength, and no heat insulating material is attached. .

Therefore, the dew that adheres to the bottom plate 13 is received by the drainage hole 13a.
The water is drained out of the machine.

Further, an air filter 24 is attached to the suction port 3 so as to be slidable along a rail (not shown), and the bottom plate 13 has a slot 1 to a collar piece 13b for preventing the air filter 14 from floating up.
are formed by bending them together.

As shown in FIG. 4, the air filter 24 is made by covering a rectangular frame-shaped wire 25 coated with resin 26 with a resin net 27 made of PP, Tetron, Saran, etc. larger than the frame of the wire 25, and then attaching it with a stapler or the like. It is temporarily fixed, heat-sealed using electrodes 28 and 29 having a width in the longitudinal direction, and the excess portion is later cut off with a cutter or the like.

As mentioned above, the present invention is divided by a partition plate into a room having an evaporator and a blower and a room having a compressor and a water-cooled condenser, and the compressor is disposed above the water-cooled condenser. At the same time, a dew pan is provided to collect dew adhering to the suction pipe of the compressor, and a drain hole is formed in the dew pan at a position facing the water-cooled condenser, so that the compressor cannot be repaired or inspected. It has great practical effects, such as making it easier to clean water, preventing liquid from returning from the condenser to the compressor, and improving condensing capacity by effectively utilizing dew that adheres to the compressor suction pipe, which was previously simply drained. .
