[0010] In addition to FIGS. 1 to 9, air conditioning equipment and the like are provided in the same manner as in FIG. In the figure, 3
Denotes a water-cooled condenser provided in the cooling water pipe 2, 6 denotes a cooling water inlet valve in the water-cooled condenser 3, and 7 denotes a water-cooled condenser 3.
, A cooling water outlet valve, 8 is a number of cooling pipes provided in parallel inside the water-cooled condenser 3, and 9 is provided between the cooling water outlet valve 7 of the cooling water pipe 2 and the water-cooled condenser 3. Drain valve.

Reference numeral 13 denotes a lid provided on the longitudinal end face of the water-cooled condenser 3, which is fastened to the body of the water-cooled condenser 3 by fasteners 14 consisting of bolts and nuts. Reference numeral 15 denotes a cleaning aid, which is a handle bar 18 formed of a tubular body, fastened to one side of the joint 16, and provided with a drawer hole 17 near the joint 16.
And a tube-shaped insertion guide rod 20 connected to the joint 16 of the handle bar 18 by a flare nut 19 screwed into the handle 16 on the side opposite to the handle rod 18.

The handle bar 18 is ergonomically manufactured to have a thickness that is easy to grasp. Reference numeral 21 denotes a cleaning body. A brush 22 inserted into the cooling pipe 8 of the water-cooled condenser 3 is connected to the tip, and is slidably inserted into the insertion guide rod 20 from the front end to pull out the drawing hole 17 of the handle rod 18. Flexible strip 23 made of an elastic material such as a piano wire drawn from
It is constituted by. 24 is a cleaning aid 15
And a cleaning tool constituted by the cleaning body 21.

In the water-cooled condenser cleaning tool configured as described above, the inside of the cooling pipe 8 is cleaned as described below. That is, the air conditioning equipment including the pump 5 is stopped, and the cooling water inlet valve 6 and the cooling water outlet valve 7 are fully closed. Then, the drain valve 9 is opened to drain the cooling water in the cooling pipe 8, and the lid 13 on the end face of the water-cooled condenser 3 is removed.

In this state, the worker grasps the handle bar 18 of the cleaning aid 15 and the elastic flexible strip 23 of the cleaning body 21 together in the cleaning tool 24 shown in FIG. 1, and as shown in FIG. The brush 22 of the cleaning aid 15 and the front end side of the insertion guide bar 20 are inserted into the opening of the cooling pipe 8. Then, in the state shown in FIG.
While holding it together, remove and insert the cooling pipe 8
Eliminate foreign matter adhering to the inside.

Next, in the state shown in FIG. 5, only the elastic flexible strip 23 is released from the hand, and only the handle bar 18 is pulled out from the cooling pipe 8 as shown in FIG. At this time, since the brush 22 is in contact with the inner surface of the cooling pipe 8 in a state of being pressed, the brush 22 does not move toward the opening end of the cooling pipe 8.

Then, in the state shown in FIG.
In step 4, the operator grasps the handle bar 18 of the cleaning aid 15 and the elastic flexible strip 23 of the cleaning body 21 together, and inserts the insertion guide rod 20 of the cleaning aid 15 into the cooling pipe 8 again. . As a result, the brush 22 moves to the back side of the cooling pipe 8 as compared with the previous time, and in this state, the pull-out operation is performed again while holding the handle bar 18 and the elastic flexible strip 23 together,
Foreign matter adhering to the inside of the cooling pipe 8 on the back side compared to the previous time is eliminated.

The operation of removing such foreign matter is repeated, and the inside of the cooling pipe 8 is cleaned until the brush 22 reaches the opening at the other end of the cooling pipe 8. The other cooling pipes 8 arranged in parallel are also cleaned by the same operation. As described above, in the cleaning operation using the cleaning tool 24, the worker grips the handle bar 18 of the cleaning aid 15 and the elastic flexible strip 23 of the cleaning body 24 together, and An operation of inserting and removing the body 21 is performed.

Therefore, the inside of the cooling pipe 8 can be easily rubbed by the brush 22, and the cleaning can be efficiently performed with a small amount of labor and the work efficiency can be improved. After the cleaning, the lid 13 on the end face of the water-cooled condenser 3 is closed.
Is mounted, and the cooling water inlet valve 6 is fully opened. Since the drain valve 9 is opened in this state, water is passed through the water-cooled condenser 3 to cause foreign matter to flow out of the drain valve 9 to clean the inside of the cooling pipe 8. Thereafter, the drain valve 9 is closed and the cooling water outlet valve 7 is fully opened. Thereby, the air-conditioning equipment returns to the operable state.

Embodiment 2 A cleaning tool for a water-cooled condenser as described below can be easily realized by applying the configuration of the embodiment shown in FIGS. And the above-mentioned FIGS.
The following operation can be obtained together with the operation in the embodiment of FIG. That is, the insertion guide bar 20 is fastened to the joint 16 of the handle bar 18 by the flare nut 19. For this reason, the insertion guide rod 20 is
It can be easily attached and detached.

Therefore, several kinds of insertion guide rods 20 having appropriate lengths are prepared. Then, the length of the cooling pipe 8 of the water-cooled condenser 3 and the condition of the working space at the cleaning work site, that is, the pull-out margin of the insertion guide rod 20 are changed to the handle rod. Attach to 18. Thereby, the cleaning operation can be further facilitated, and the operation efficiency can be improved.
