Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a refrigeration system equipped with a compressor that generates high pressure inside a container.

BACKGROUND ART In recent years, refrigeration systems applied to refrigerators and the like often use a compressor such as a rotary compressor that generates high pressure inside a container from the viewpoint of cost and power consumption.

An example of the conventional refrigeration system mentioned above will be described below with reference to the drawings.

Figure 3 shows a system piping diagram of a refrigeration system conventionally applied to refrigerators, etc., where 1 is a compressor, 2 is a condenser, 3 is a capillary reach tube, 4 is a cooler, and 5 is a first 6 is a second suction pipe, and 7 is an accumulator provided between the first suction pipe 5 and the second suction pipe 6. Further, the container 1a of the compressor 1 houses mechanical parts such as a cylinder 1b, a piston 1c, and a vane 1d.

FIG. 4 is a detailed view of the area around the compressor 1 of the refrigerator equipped with the refrigeration system shown in FIG.
9 is a damping material made of hard rubber or the like attached to the first suction pipe 5, 10 is a bottom plate of the refrigerator on which the compressor 1 is mounted, and 11 is a refrigerant sealed in this refrigeration device. , 12 is oil in the compressor 1.

Further, the first suction pipe 5 is provided with a substantially U-shaped trap 5a for vibration isolation in order to prevent the vibrations of the compressor 1 from propagating to the refrigerator body 8.

The operation of the refrigeration system configured as described above will be explained below.

Normally, in such a refrigeration system, the temperature of the person to be cooled is often adjusted by starting and stopping the compressor 1.
In this case, when stopped, the high temperature and high pressure refrigerant 11 in the container 1a flows into the cylinder 1b and piston 1 of the compressor 1.
c, the second one on the low pressure side from the gap between the sliding parts such as the vane 1d.
It flows into the suction pipe 6 direction.

This inflow rate continues until the refrigerant 11 reaches the cooler 4 and is sequentially condensed in the cooler 4 with low temperature and low pressure, resulting in a good balance between high and low pressure.

Additionally, the oil 12 sealed inside the compressor 1 along with the refrigerant 11 also flows into the low pressure side, but the oil 12 with a large specific gravity does not reach the cooler 4, and as shown in FIG. second in position
It accumulates in the suction pipe 6 and the large-capacity accumulator 7.

Next, when the compressor 1 starts operating, first the oil in the accumulator 7 and the second suction pipe 6 is sucked in, and then the refrigerant 11 in the first suction pipe 5 is sucked in.

However, at the start of this operation, the refrigerant 11 in the first suction pipe 5 expands rapidly, resulting in a very low temperature, and a large amount of frost forms on the surface of the first suction pipe 5, after which the operation becomes steady. As this happens, this frost turns into dew and flows downward.

Normally, in such a refrigeration system, a damping material 9 such as rubber is attached to the first suction pipe 5 in order to prevent vibrations, and a trap 5a is provided on the suction pipe 5 as shown in FIG. The dew adhering to the suction pipe 5 falls downward from the lower tip of the trap 5a.

Problems that the invention aims to solve As described above, in conventional refrigeration equipment, water falls downward when the compressor 1 starts and stops, causing rust on the equipment, and in refrigerators and the like, water drips onto the floor. It had the problem of falling.

In view of the above-mentioned problems, the present invention provides a refrigeration system that prevents water from falling downward even when the compressor is in operation or stopped.

Means for Solving the Problems In order to solve the above problems, the refrigeration system of the present invention is equipped with a damping material having heat insulating properties, including the lower end of the trap of the first suction pipe. .

Function The present invention has the above-described structure to keep the suction pipe warm even when the compressor starts operating, and to dam the dew flowing from the upper part to the tip of the trap.

Embodiment A refrigeration system according to an embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the refrigeration system of the present invention, 13 is a refrigerator main body, 14 is a compressor that makes the inside of the container high pressure, 15 is a first suction pipe, and the refrigerator main body 13 A trap 15a is provided below to prevent vibrations from propagating to. Numeral 16 is a damping material attached for vibration isolation, similar to the trap 15a, and is made of a heat insulating material such as butyl rubber.

Further, 17 is an accumulator connected to the first suction pipe, and 18 is the accumulator 17.
a second suction pipe connected to the compressor 14;
It is connected to the.

Reference numerals 19 and 20 represent a refrigerant and oil sealed in the refrigeration apparatus, respectively, and 21 represents a bottom plate of the refrigerator on which the compressor is mounted.

The operation of the refrigeration system configured as described above will be explained below.

As described in the embodiment, when the compressor 14 is stopped, the accumulator 17 and the second suction pipe 18 are
The inside is filled with oil 20, and the upper part of the first suction pipe 15 and the accumulator 17 is filled with a relatively dense refrigerant 19 with a well-balanced high and low pressure.

Next, when the compressor 14 starts operating from this state, first, the oil 20 in the accumulator 17 and the second suction pipe 13 is sucked into the compressor 14, and then the oil 20 in the first suction pipe 15 and Since the refrigerant 19 in the upper part of the accumulator 17 is sucked into the compressor 14, the first suction pipe 15 is very cooled.

However, the trap 1 of the first suction pipe 15
Since the lower end of 5a is covered with a damping material 16 having heat insulating properties such as butyl rubber, frost does not form.
Also, the first suction pipe 1 excluding the tip of the trap 15a
As the operation becomes steady, the frost that has arrived at the trap 15 will replace dew and flow downward due to the heat of the compressor 14 and the temperature rise of the refrigerant 19 itself.
It is dammed by the damping material 16 attached to the lower end of the trap 15a, and accumulates at the upper part of the damping material 16 without reaching the lower end of the trap 15a, and eventually the temperature of the refrigerant 19 itself in the compressor 14 and the first suction pipe 15 rises. evaporates due to

As described above, according to this embodiment, the damping material 16 attached to the lower end of the trap 15a of the first suction pipe 15 can prevent water droplets from falling down the first suction pipe. Refrigerator bottom plate 2
It is possible to prevent the occurrence of rust and water droplets from falling onto the floor.

Effects of the invention As described above, the present invention provides vibration isolation for the suction pipe by providing a damping material with heat insulating properties on the trap provided in the suction pipe of the compressor, including the lower end of the trap. It is possible to prevent water droplets from coming from the suction pipe, prevent rust from occurring on peripheral equipment, and prevent water from falling onto the floor without adding any additional water.
