DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of a scroll type refrigerator according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a scroll type freezing apparatus according to an embodiment of the present invention, FIG. 2 is a front view showing a scroll type freezing apparatus according to an embodiment of the present invention, FIG. 3 is a perspective view of a scroll type freezing apparatus according to an embodiment of the present invention, FIG. 4 is a rear view of a scroll type freezer according to an embodiment of the present invention. FIG.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

As shown in FIGS. 1 to 4, the scroll type freezer according to the embodiment of the present invention includes a plurality of middle-temperature compressors 1, a plurality of low-temperature compressors 2, a receiver, A liquid separator, a dry filter, a liquid gas heat exchanger, a maneuvering platform 3 and an external piping connection valve 4, and is installed in one casing 10.

Here, the oil tank and the oil separator can be fused (integrated) into the oil tank / oil separator 5 so that the oil discharged from the intermediate-temperature compressor 1 and the low- And serves as an oil separator for separating the refrigerant from the refrigerant, and serves as an oil tank for storing the oil in the lower portion thereof and then supplying the oil to the compressor. To this end, the backup switch 21 may be provided on the side of the 'C' shaped frame 20.

Thus, by integrating the oil tank / oil separator 5 with the oil tank / oil separator 5, many troubles that occur when oil is supplied from the oil tank to the inside of the compressor at low pressure are solved. .

By integrating the oil tank / oil separator 5 with the oil tank / oil separator 5, it is possible to minimize the installation area of the machine room by installing the oil tank and the oil separator separately from each other.

The middle-temperature compressor (1) is installed on the upper part of the 'C' shaped frame (20) opened downward in the casing (10), and is spaced apart from the inner wall of the casing (40) and the sound absorbing material (70).

Accordingly, the vibrations generated when the compressor 1 of medium temperature is operated are not transmitted to the casing 10 or the base frame 40.

The low-temperature compressor (2) is installed on the bottom part (15) of the casing (10) on the upper part of the base frame (40) provided through the vibration proof rubber (30) so as to be accommodated inside the 'C' shaped frame Respectively.

Since the low temperature compressor 2 is not installed in direct contact with the bottom of the casing 10 but is installed through the vibration proof rubber 30, the vibration generated therefrom is not transmitted to the casing 10.

The oil tank / oil separator 5 is disposed at a predetermined distance from the upper portion of the 'C' shaped frame 20 at an upper portion of the base frame 40, And is not affected by the vibration generated in the operation of the motor (2).

Here, the high-pressure pipes 9 of the mid-temperature compressor 1 and the low-temperature compressor 2 are connected to the oil tank / oil separator 5 as shown in FIGS. 1, 2 and 4 Shaped high-pressure header 50 of FIG.

Therefore, it is possible to use one 'C' type high pressure header 50 and one oil tank / oil separator 5 at the time of the combination of the mid-temperature compressor 1 and the low-temperature compressor 2, And the installation area is minimized.

The maneuvering unit 3 is installed on the upper frame 11 of the casing 10 to facilitate the operation.

The operating state of the device can be confirmed without disassembling the cover 8 of the casing 10 by providing the high and low pressure gauge 6 and the pressure switch 7 on the side of the maneuvering board 3. [

Here, any one of the side frames 14 of the casing 10 may be detachably installed to perform the role of the cover 8.

The legs 13 installed on the lower frame 12 of the casing 10 are provided with vibration-proof pads 60 to adjust the installation height of the casing 10 The vibration which may be generated in the operation of the compressor 1 for an intermediate temperature and the compressor 2 for a low temperature can be prevented from being transmitted to the floor of the installation place.

In addition, a sound absorbing material 70 is attached to the inside of the casing 10, but it is possible to attach and detach the sound absorbing material 70 thereby to shorten the time during service, as well as to allow the compressor 1 and the low temperature compressor 2 ) So that the noise generated through the operation of the microcomputer does not leak to the outside.

Although not shown, the low-pressure safety device provided in the freezing device is operated by the operation of the backup switch 21 in the event of failure of the electronic rack controller. If the pressure rise time of the low pressure during the operation in the automatic mode is longer than the set time, Mode, so that the refrigerator can be operated. This makes it possible to prevent damage to the product when there is no manager at night.
