Abstract

Disclosed is a multi-air conditioner refrigerant piping structure for flowing refrigerant from a room air conditioner and a package air conditioner into a accumulator through a first refrigerant line and a second refrigerant line, respectively, having two arms parallel to the accumulator inlet. It relates to a multi-air conditioner refrigerant pipe structure in which one joint is coupled, and the first refrigerant pipe and the second refrigerant pipe are respectively coupled to the arms of the joint.

Accordingly, the multi-air conditioner refrigerant pipe structure according to the present invention has joints in which the arms are parallel to each other at the inlet of the accumulator, and connects each refrigerant pipe to the arm of the joint so that the refrigerant flows almost in parallel, thereby allowing the refrigerant in the refrigerant pipe to flow into each other. It is possible to smooth the flow of refrigerant by reducing friction.

Description

Structure of refrigerants pipe for multi air-conditioner

The present invention relates to an air conditioner accumulator, and more particularly, to a refrigerant pipe structure of a multi-air conditioner for smoothly flowing a refrigerant in a multi-air conditioner.

An air conditioner usually consists of one indoor unit and one outdoor unit. Figure 1 shows the configuration of the cooling system made in the air conditioner indoor unit and outdoor unit in this case.

As shown in FIG. 1, the refrigerant flows out of the evaporator 10 in a high temperature gas state, passes through the accumulator 20 for filtering out the predetermined refrigerant remaining in the liquid state, and is directed back to the compressor 30.

Thereafter, the refrigerant compressed to high temperature and high pressure by the compressor 30 becomes a low-temperature, high-pressure liquid refrigerant through the condenser 40 and moves to the evaporator 10. Arrows in the figure indicate the flow direction of the refrigerant.

As described above, an air conditioner usually consists of one indoor unit and an outdoor unit, and has a flow of a refrigerant as shown in FIG. 1.

However, recent multi-air conditioners operate two indoor units with one outdoor unit. In other words, one indoor air conditioner is placed in a living room and the other in a room, and two air conditioners are used in a room.

In this case, as shown in Fig. 2, the refrigerant from the room air conditioner refrigerant piping 1 and the package air conditioner (commonly referred to as the stand type air conditioner) are flow paths of the refrigerant from the room air conditioner (commonly referred to as the wall-mounted air conditioner). A package air conditioner refrigerant piping (2) is required.

By the way, the refrigerant flow of the conventional air conditioner, as shown in Figure 2, a hole in the package air conditioner refrigerant piping (2) is used to connect the end of the room air conditioner refrigerant piping (1).

In this case, a problem arises in part A that the flow of the refrigerant from the room air conditioner is not affected by the air conditioner refrigerant pipe 1 in the bent room. Therefore, the flow of the refrigerant is not smooth, and the performance of the air conditioner is reduced.

In view of the above problems, an object of the present invention is to smooth the flow of the refrigerant by flowing the refrigerant from the evaporators in the multi-air conditioner to the accumulator in parallel through separate refrigerant pipes.

The multi-air conditioner refrigerant pipe structure according to the present invention, in the multi-air conditioner refrigerant pipe structure for flowing the refrigerant from the room air conditioner evaporator and the package air conditioner evaporator to the accumulator through the first refrigerant pipe and the second refrigerant pipe, respectively, A joint having two arms in parallel is coupled, and the first refrigerant pipe and the second refrigerant pipe are respectively coupled to the arms of the joint.

Hereinafter, the present invention will be described in detail with reference to FIG. 3. 3 is a cross-sectional view showing a multi-air conditioner refrigerant pipe structure according to the present invention.

As shown in FIG. 3, a first refrigerant pipe 3, which is a pipe for the refrigerant from the room air conditioner, and a second refrigerant pipe 4, which is a pipe for the refrigerant from the package air conditioner, are provided. The direction of the arrow in the figure indicates the flow direction of the refrigerant.

In the multi-air conditioner refrigerant pipe structure according to the present invention, a joint (8; joint) having two arms (7) parallel to each other at the inlet of the accumulator (24) is connected, and the arm (arm; arm) of the joint (8). ) Connect the first refrigerant pipe (5) and the second refrigerant pipe (6), respectively.

The joint 8 may be manufactured in a Y or U shape. This joint 8 is configured to have two arms, each arm being designed parallel to each other. Therefore, in the coolant flow to the accumulator, the coolant (i.e., the coolant from the room air conditioner and the package air conditioner) has little friction with each other and flows smoothly.

Meanwhile, the first refrigerant pipe 5 and the second refrigerant pipe 6 may be assembled to the arms 7 of the joint 8, respectively. Alternatively, the first refrigerant pipe 5 and the second refrigerant pipe 6 may be welded to and coupled to the arms 7 of the joint 8.

As a result, the flow of the refrigerant from the evaporators in the multi-air conditioner can be smoothly flowed to the accumulator 22 without being disturbed from each other.

As described above, the multi-air conditioner refrigerant pipe structure according to the present invention connects the refrigerant pipes, which are flow paths of the refrigerant from the room air conditioner and the refrigerant from the package air conditioner, to two parallel arms of the joint connected to the inlet of the accumulator, respectively. Therefore, by flowing the refrigerant almost in parallel, the friction between the refrigerants can be reduced, and the refrigerant can be smoothly flowed to the accumulator.
