Abstract

PURPOSE:To reduce the outflow of tailings of fibers into refrigerant, by a method wherein drying agent, filling the main body of a drier, is enveloped by the first filter of short fibers while the outside thereof is enveloped by the second filter of long fibers. CONSTITUTION:Drying agent 9 is enveloped by the first filter 12 of short fibers and the outside thereof is enveloped by the second filter 15 of long fibers; therefore, the tailings of fibers for the first filter 12 are collected by the second filter 13. Further, the second filter 13 is formed of long fibers; therefore, the napping of the surface thereof is very few, whereby the tailings of the fibers will never flow into refrigerant and the removing performance of foreign materials in the refrigerant may be improved. As a result, the strainer of lubricating oil for a compressor, interposed in a refrigerating cycle, may be protected from clogging for a long period of time and the seizing trouble of the sliding parts of the compressor, which is due to the shortage of feeding of the lubricating oil, may be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dryer receiver provided for removing unnecessary moisture during the refrigeration cycle of an air conditioner.

The refrigeration cycle of a conventional air conditioner is constructed as shown in FIG. Then, the evaporator 4 removes ambient heat and returns to the compressor 1. A dryer receiver 5 is interposed between the condenser 2 and the evaporator 4. 6.7 is a blower. As shown in FIG. 4, the dryer receiver 5 is constructed by mounting a desiccant 9 inside a cylindrical dryer receiver main body 8, and the refrigerant is dehydrated by contacting the desiccant 9, and the dryer receiver main body 8 is dehydrated. It accumulates at the bottom of the.

Conventionally, the desiccant 9 is wrapped in a storage bag, specifically a felt filter 10 made of cloth-like staple fibers intertwined with each other.As shown in FIG. Divided into multiple storage areas.

With this configuration, the dryer receiver 5
The refrigerant is dehydrated, and the powdered desiccant 9 is prevented from flowing out by the filtering action of the filter 10. The filter 10 also serves to capture minute wear particles that move due to the flow of refrigerant.

Furthermore, since the fibers are made of short fibers and have a lot of unstable fuzz on their surface, conventional filters are used to prevent these unstable parts from flowing out into the refrigerant due to the flow of the refrigerant. A resin coating is applied to the surface of 10 to reduce fuzz.

Problems to be Solved by the Invention In such a conventional configuration, fluffing can be reduced by coating the surface of the filter 10 with resin, but during long-term use, the resin coated on the filter 10 will dissolve due to the dissolving action of the refrigerant. It peels off and flows out,
Similar to the fiber waste in the filter 10, δ becomes harmful foreign matter in the refrigerant cycle.

These foreign substances get mixed into the lubricating oil of compressor 1,
This causes the oil strainer (not shown) to become clogged, resulting in insufficient oil supply and poor lubrication of the compressor 1.

An object of the present invention is to provide a dryer receiver that can reduce the amount of foreign matter in a cryostat compared to the conventional method.

Means for Solving the Problems In the dryer receiver of the present invention, a dryer receiver main body is inserted during the refrigeration cycle, a desiccant is installed inside the dryer receiver main body, and the desiccant is applied to the first short fiber. The first filter is wrapped with a second filter made of long fibers, and the outside of the first filter is wrapped with a second filter made of long fibers.

Effect: According to this configuration, the desiccant is the first desiccant. The second filter is wrapped in a double filter, and the fiber waste flowing into the refrigerant from the surface of the first filter made of short fibers on the inside is captured by the second filter made of long fibers on the outside. There is no need for traditional resin coatings as there is no flow out of the second filter. Since the second filter is made of long fibers, there is no fuzz as seen on the surface of the first filter, and less fiber waste flows out from the second filter into the refrigerant.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 and 2. Components having the same functions as those shown in FIGS. 3 and 4 showing the conventional example will be described with the same reference numerals.

FIG. 1 shows a dryer receiver of the present invention, in which a desiccant 9 mounted inside a dryer receiver main body 8 is placed in a storage bag A. The storage bag A has a double structure of a first filter 12 and a second filter 12, 13, and the desiccant 9 is wrapped in the first filter 12, and as shown in FIG. 2, the top of the first filter 12 is Furthermore, it is surrounded by a second filter 13. The first filter 12 is the filter 10 seen in FIG.
It is made of the same material as , and is made of felt made of intertwined short fibers. The second filter 13 is made of ultrafine, long-fiber polyester fibers woven into a cloth shape.

With this configuration, the powdered desiccant 9 is captured by the first filter 12 and does not flow out of the first filter 12. If the surface of the first filter 12 is not coated with a resin coating as described above, fuzz will be seen, but the fiber waste flowing out from the first filter 12 into the refrigerant is captured by the second filter 13. The liquid does not leak out of the second filter 13.

Since the second filter 13 is made of long fibers as described above, there is very little fluff on its surface, and no fiber waste was observed flowing from the surface of the second filter 13 into the refrigerant. . Furthermore, minute abrasion powder contained in the refrigerant that has flowed into the dryer receiver body 8 from the compressor 1 via the condenser 2 is captured on the surface of the second filter 13 with a fine weave. This dryer cashier/'
The ability of e5 to remove foreign matter from the refrigerant is stable over a long period of time, and it can prevent clogging of the oil strainer of compressor 1, resulting in the prevention of seizing accidents in the m moving parts of compressor 1. It is.

Effects of the Invention As described above, according to the present invention, the desiccant is wrapped in the first filter made of short fibers, and the outside of the first filter is wrapped in the second filter. There is no need to apply a conventional resin coating to the outer surface of the first filter, and since the second filter is made of long fibers, there is very little fluff on the surface. No fiber waste flows out from the surface of the second filter into the refrigerant, and the ability to remove foreign matter from the refrigerant is improved.

As a result, the oil strainer for lubricating oil in the compressor, which is installed in the refrigerant cycle, can be protected from clogging for a long period of time, and accidents such as seizing of the sliding parts of the compressor due to insufficient lubricating oil supply can be prevented. It is possible.
