The present invention relates to a heat insulating hose for air conditioner refrigerant pipe, more specifically, it is possible to manufacture easily and inexpensively by attaching three or four heat pipes such as high pressure and low pressure refrigerant pipes and control lines integrally. The present invention relates to a heat insulating hose for air conditioner refrigerant pipe having excellent heat insulation and insulation effect.

In general, an air conditioner includes an indoor unit in which an evaporator is installed and an outdoor unit in which a compressor and a condenser are installed. The indoor unit and the outdoor unit are connected to each other through a refrigerant pipe for high pressure and low pressure to be delivered to the refrigerant in the gas state and the liquid state, and a control line (control signal for controlling the outdoor unit from the control unit installed in the indoor unit) Line) is connected.

The air conditioner is an apparatus for cooling the room by using heat exchange between the evaporator and the condenser. In the refrigerant pipe, which is a passage through which the refrigerant moves, it is possible to insulate the heat so that heat is not exchanged with the outside.

Therefore, in the conventional air conditioner, various structures for heat insulation and insulation of the high pressure and low pressure refrigerant pipes connecting the indoor unit and the outdoor unit are used.

For example, after connecting each refrigerant pipe and wrapping it with synthetic resin foam and then taping (tapping it with tape) to fix it, the space between each tube is arranged with foam insulation as appropriately spaced tubes for each refrigerant pipe. The structure which fills and coats it with a synthetic resin pipe etc. is used.

However, in the case of a structure in which each refrigerant pipe is wrapped with a synthetic foam and taped, the work process is complicated, sufficient thermal insulation and insulation effect are not obtained, and a long time is required for taping when the indoor unit and the outdoor unit are far from each other. have.

In the case of the structure in which the refrigerant insulation tube is filled with foam insulation and coated with a synthetic resin tube, the structure is complicated, and thus it is not easy to manufacture. .

An object of the present invention is to solve the problems as described above, and is formed by rolling the foamed synthetic resin sheet round and attached to three or four of the insulation pipes for the high-pressure and low-pressure refrigerant pipes and control lines are integrally attached (heat It is to provide a heat insulating hose for air conditioner refrigerant piping that can be manufactured at low cost, easy to construct, and excellent in heat insulation and insulation effect.

The heat insulating hose for air conditioner refrigerant pipe proposed by the present invention is composed of three heat pipes having a passage formed at the center thereof so that the low pressure and high pressure refrigerant pipes and control lines are inserted therein, and the three heat pipes have a triangle A portion of the outer surfaces disposed to be in close contact and in contact with each other are integrally attached.

The insulation tube is formed of a foamed synthetic resin.

The heat insulating tube is formed by rolling a foamed synthetic resin sheet and heat-sealing the surfaces in contact with each other.

The heat insulating hose for air conditioner refrigerant pipe of the present invention is disposed on one side of the three heat insulating pipes and is in close contact with each other, and a part of the outer surface which is in contact with each other is integrally installed, and may further include a drain heat insulating pipe with the drain hose inserted therein. Do.

Next, a preferred embodiment of the heat insulating hose for air conditioner refrigerant pipe according to the present invention will be described in detail with reference to the drawings.

First, an embodiment of the heat insulating hose for air conditioner refrigerant pipe according to the present invention, as shown in Figures 1 and 2, the low-pressure and high-pressure refrigerant pipe and the control line is inserted into the passage 12, (22) ) And (32) are formed of three heat insulating tubes (10), (20), (30).

The thermal insulation pipe (10), (20), and (30) is a low pressure thermal insulation tube 10, the low pressure refrigerant pipe is inserted therein, and a high pressure thermal insulation tube 20 is inserted into the high pressure refrigerant pipe therein; , Control line is made of a control insulating tube 30 is inserted therein.

The low pressure thermal insulation tube 10 has a larger inner diameter and outer diameter than the high pressure thermal insulation tube 20 and the control thermal insulation tube 30.

In general, since the low pressure refrigerant pipe is formed larger than the high pressure refrigerant pipe of the air conditioner, it is preferable that the low pressure heat insulating pipe 10 is formed larger than the high pressure heat insulating pipe 20.

As shown in FIG. 3, the passages 12 and 22 formed at the center of the low pressure heat insulating tube 10 and the high pressure heat insulating tube 20 are respectively a low pressure refrigerant pipe 2 and a high pressure refrigerant. Since it is a space for inserting the pipe 4, it is formed with the inner diameter corresponding to the outer diameter of the low pressure refrigerant pipe 2 and the high pressure refrigerant pipe 4, respectively. The inner diameters of the passages 12 and 22 are slightly larger in diameter than the outer diameters of the low pressure refrigerant pipe 2 and the high pressure refrigerant pipe 4, respectively. It is preferable because the operation for inserting the refrigerant refrigerant pipe 4 is made easy. For example, the inner diameters of the passages 12 and 22 are set to be 0.5 to 5 mm larger than the outer diameters of the low pressure refrigerant pipe 2 and the high pressure refrigerant pipe 4. At this time, if the inner diameters of the passages 12 and 22 are too large, sufficient thermal insulation and thermal insulation effects on the low pressure refrigerant pipe 2 and the high pressure refrigerant pipe 4 are not obtained, and thus the insertion is easy at the time of operation. It is preferable to form with the minimum inner diameter.

Since the passage 32 formed in the control insulation tube 30 has a smaller control line thickness than the outer diameter of the high pressure refrigerant pipe 4, the passage 32 formed in the control insulation tube 30 is smaller than the passage 22 of the high pressure insulation tube 20. It is also possible to manufacture by uniformly setting the outer diameter of the high-pressure insulation tube 20 and the control insulation tube 30 and the inner diameters of the passages 22 and 32 for the purpose of unification and common use of the product.

In the case of the control line 6 inserted into the passage 32 of the control insulating tube 30, heat transfer between the low pressure refrigerant pipe 2 and the high pressure refrigerant pipe 4 is blocked, and Since only heat insulation is required, a space may exist between the passage 32 and the control line 6. Therefore, the size of the inner diameter of the passage 32 can be freely set.

It is also possible to insert a wire for supplying power to the outdoor unit together with the control line 6 in the control heat insulating tube 30.

As shown in Fig. 2, the heat insulating tubes 10, 20, and 30 are formed by integrally attaching a part of the outer surfaces which form a triangle and are in close contact with each other.

The insulation tubes 10, 20, and 30 are each configured to be in contact with each other a part of the outer surface, each part of the outer surface in contact with each other integrally attached by a method such as thermal fusion, ultrasonic fusion.

The thermal insulation tubes 10, 20, and 30 are formed of a foamed synthetic resin (for example, PE, PC, PA, etc.). For example, the heat insulating tubes 10, 20, and 30 are formed by integrally attaching the surfaces of the foamed synthetic resin sheets which are in contact with each other by thermal fusion or the like.

As shown in Fig. 4, the thermal insulation tubes 10, 20, and 30 have pores in the interior 14, 24, 34 and the exterior 16, 26, 36, respectively. It is also possible to construct a double tube composed of foamed resins of different sizes. In other words, the inner 14, 24, and 34 are formed of a foamed synthetic resin having small pores, and the outer 16, 26, and 36 are formed of a foamed synthetic resin having large pores. It is also possible to configure the pipe to be located.

In the case where the pores of the expanded synthetic resin are largely formed, there is a possibility that the fusion may be incomplete when the sheets are brought into contact with each other by rolling the sheets. Therefore, it is preferable to arrange the thermally sealed foamed resin sheets with small pores formed therein. Do.

In forming the double tube in the above, the thermal insulation pipes 10, 20, and 30 are formed by heat-sealing two foamed synthetic resin sheets having different pores and then rolling them round and heat-sealing the surfaces in contact with each other. do.

As shown in FIG. 4, the heat insulating tubes 10, 20, and 30 may be provided with the uneven portion 18 on the outer surface.

The uneven portion 18 is formed using an embossing process or the like.

When the concave-convex portion 18 is formed on the outer surface as described above, slippage is prevented at the time of piping work and durability is improved.

And another embodiment of the heat insulating hose for air conditioner refrigerant pipe according to the present invention is installed integrally attached to one of the three heat insulating tubes (10), (20), (30) as shown in Figs. The drain hose further includes a heat insulating tube 40 into which a drain hose (not shown) is inserted.

The drain insulation tube 40 is inserted with a drain hose (not shown) for draining the water generated by condensation on the surface of the evaporator of the indoor unit. In general, since the drain hose is formed in a corrugated pipe shape and its diameter is similar to that of the low pressure refrigerant pipe 2, the drain insulation tube 40 has an inner diameter or a larger inner diameter corresponding to the low pressure insulation tube 10. It is preferable to form.

The drain thermal insulation tube 40 is integrally attached to two adjacent thermal insulation tubes 10 and 30 by heat fusion or ultrasonic fusion. The four thermal insulation tubes 10, 20, 30, and 40 are arranged to form a square and integrated.

The insulation hose for the air conditioner refrigerant pipe according to the present invention constituted as described above is cut to the required length in the field, and then the low pressure refrigerant pipe (2), the high pressure refrigerant pipe (4), three control lines (6) The installation work is completed by performing piping work connecting the indoor unit and the outdoor unit in the state of being inserted into the heat insulating tubes 10, 20, and 30.

In addition, if the drain hose is to be piped together with the low pressure refrigerant pipe (2), the high pressure refrigerant pipe (4), the control line (6), etc., four heat insulating pipes (10), (20), (30), (40) The pipe work is carried out using another embodiment in which) is integrally formed.
