In order to prevent heat loss from the heat exchange part of the user-side water cooler configured in this way and dew condensation from the piping part, the entire circumference of the cooling element part 17d surrounded by the side plates 17a is made of urethane foam resin or the like. Completely insulated with in-situ foam material and formed into a rectangular parallelepiped shape, it is installed on the connecting plate 16, and the rear part is connected to the support column 13.
The front portion is fixed with the connecting plate 18 as described above. At this time, the bottom surface of the water cooler 17 is almost in contact with the top surface of the condenser 3.

Reference numeral 18 denotes a connecting plate made of a steel plate with an L-shaped cross section, one side of which is connected between the side plates 17a, the other side of which is spanned between the front supports 13, and a through hole 16a of the support 13 and a through hole 18a of the connecting plate 18. is fixed through the bolt.

Reference numeral 25 denotes a compressor that is mounted on the compressor support plate 12 via vibration isolating rubber (not shown) in the front space A formed by the arrangement of the condenser 3 and the water cooler 17. Measures are taken to prevent vibrations caused by the operation of the compressor 25 from propagating to the underframe 4. Further, the discharge side of this compressor 25 is connected to each condensing element 10a.
The suction side is connected to the inner and outer pipes of the water cooler 17.

Reference numeral 21 denotes a rear plate made of a relatively thin steel plate, which has a plurality of through holes 21a at both ends thereof, and is fixed to both side panels 11 with mounting screws through these through holes 21a.

It is fixed with the mounting screw.

Reference numeral 23 denotes an upper front panel formed by bending a relatively thin steel plate into an L-shape around the periphery.

Next, the control operation of the refrigeration system will be explained.

In FIG. 4, the high-temperature, high-pressure gas refrigerant discharged from the compressor 25 enters the refrigerant pipe of the unused side condenser 10, exchanges heat with the cooling water, and then becomes a high-pressure liquid refrigerant. 26, the refrigerant becomes a low-pressure liquid/gas mixed refrigerant and enters the user-side water cooler 17, exchanges heat with the cold water, and then returns to the compressor 13 as a gas refrigerant.

This forms a refrigeration cycle, and this operation is repeated thereafter, but the noise generated from the compressor 25 is suppressed by the front panel 23, since the non-use side condenser 10 and the use side water cooler 17 are formed as part of the sound insulation wall. 24
Together with the sound insulation, it is attenuated and can provide low noise to the outside.

In the above embodiment, the water-cooled condenser 10 is provided on the non-use side and the water cooler 17 is provided on the use side, but the arrangement may be reversed depending on the purpose of use. Place the container 17 on the underframe 4,
The water-cooled condenser 10 may be installed at the top of the main body.

As described above, in this invention, the water cooler and the water-cooled condenser are formed from foamed resin into a rectangular parallelepiped shape, and one of the water coolers and the water-cooled condenser is installed in the rear part of the underframe, and the other is installed above it. Since the compressor is installed in the space, the water cooler and water-cooled condenser can be used as a sound insulating wall for the compressor, and there is no need to worry about condensation dripping even if the water cooler is placed on the top of the main unit. can be placed relatively low on the main body for easy operation.
