Abstract

The utility model discloses an air conditioning refrigerant shunting tee which comprises a liquid inlet pipe, a first liquid outlet pipe and a second liquid outlet pipe, wherein the first liquid outlet pipe and the second liquid outlet pipe are communicated with the liquid inlet pipe, the inside diameter of the outlet of the first liquid outlet pipe is equal to that of the outlet of the second liquid outlet pipe, and a reducing part is arranged on the second liquid outlet pipe. In the air conditioning refrigerant shunting tee, one liquid outlet pipe is provided with the reducing part, and therefore, refrigerant which flows into the tee from the liquid inlet pipe of the tee has different flowing resistances on two branches because the section sizes at the inlets of the two first liquid outlet pipes are different, so that the fact that more refrigerant is distributed to a lower branch due to the gravity action is reduced, so that refrigerant distribution in two flow paths is nearly uniform, and the heat exchange efficiency of a heat exchanger is improved while the cost is not increased.

Description

The air conditioner coolant diversion three-way

Technical field

The utility model relates to air-conditioning system, is specifically related to the air conditioner coolant diversion three-way.

Background technology

At present, air-conditioner has been applied to family and office space more and more, for people provide comfortable live and work environment.Usually, in air-conditioning system, the multithread road design that evaporimeter usually adopts " few advance to have more " is with the heat transfer coefficient and pressure drop of the balance refrigerant relation between the two, thereby makes evaporimeter give play to best ability and efficiency, and modal structure is to realize two shunt by the coolant distribution threeway.

But, find that in use there is the problem that the performance of heat exchanger can not fine performance in existing air-conditioner, main cause is each refrigerant maldistribution between along separate routes of heat exchanger.The structure of existing coolant distribution threeway as shown in Figure 1, the flow schematic diagram of refrigerant as shown in Figure 2 during use, by Fig. 1, Fig. 2 as seen, two drain pipes, 2,3 structures of existing coolant distribution threeway are identical, therefore, the flow resistance of two streams of heat exchanger is almost suitable, like this, because the effect of refrigerant self gravitation has caused the cold medium flux of bottom drain pipe 3 bigger than normal, cause the shunting inequality of refrigerant in the upper and

lower drain pipe

2,3, thereby influenced the heat exchange effect of heat exchanger.

The utility model content

Technical problem to be solved in the utility model is to solve the uneven problem of refrigerant distribution in the many shunt of air-condition heat exchanger.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of air conditioner coolant diversion three-way, comprise a feed tube and first, second two drain pipes that communicate with described feed tube, the internal diameter in the exit of described first, second drain pipe is identical, and wherein said second drain pipe has a reducing diameter part.

In such scheme, the inner chamber of described reducing diameter part is horn-like.

In such scheme, the reducing diameter part on described second drain pipe bring out mouthful a outlet greatly towards described second drain pipe.

The utility model, one of them drain pipe has a reducing diameter part, like this, the refrigerant that flows into from the feed tube of threeway is because the sectional dimension difference of two drain pipe import departments causes two flow resistance differences in the shunt, thereby reduced time shunt because the refrigerant that the gravity effect causes distributes more phenomenon, make the refrigerant of two streams distribute convergence even, on the basis that does not increase cost, improved the heat exchange efficiency of heat exchanger, and simple in structure.

Description of drawings

Fig. 1 is the structural representation of existing air conditioner coolant diversion three-way;

Fig. 2 is the flow schematic diagram of refrigerant in air conditioner coolant diversion three-way shown in Figure 1;

A kind of specific embodiment structural representation of the air conditioner coolant diversion three-way that Fig. 3 provides for the utility model;

Fig. 4 is the flow schematic diagram of refrigerant in air conditioner coolant diversion three-way shown in Figure 3.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is made detailed explanation.

As shown in Figure 3, the air conditioner coolant diversion three-way that the utility model provides comprises a feed tube 1 and first, second two

drain pipes

2,3 that communicate with feed tube 1, the internal diameter in the exit of first,

second drain pipe

2,3 is identical, wherein second drain pipe 3 has a reducing diameter part 31, and the inner chamber of reducing diameter part 31 is horn-like and brings out mouthful outlet towards drain pipe 3 greatly.

The utility model in use, drain pipe 2 connects down along separate routes, drain pipe 3 connects along separate routes, refrigerant from feed tube 1 inflow, entering first, second two

drain pipes

2,3 o'clock, the flow resistance of the refrigerant of the reducing diameter part 31 of second drain pipe 3 of wherein flowing through is bigger, thereby has avoided because the bigger phenomenon of cold medium flux of the following shunt that gravity causes, promptly the cold medium flux of two streams is tending towards evenly, and the flow schematic diagram of its refrigerant as shown in Figure 4.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.

Claims

1. the air conditioner coolant diversion three-way comprises a feed tube and first, second two drain pipes that communicate with described feed tube, and the internal diameter in the exit of described first, second drain pipe is identical, it is characterized in that, wherein said second drain pipe has a reducing diameter part.

2. air conditioner coolant diversion three-way as claimed in claim 1 is characterized in that the inner chamber of described reducing diameter part is horn-like.
