Description
Technical Field
[0001] The utility model relates to the technical field of refrigerant distributors, in particular to a refrigerant distributor for air conditioners. Background Art
[0002] With the development of society, air conditioners have become indispensable electrical appliances in people's lives and work. Air conditioners achieve the adjustment of indoor temperature through a refrigeration cycle. In this process, the refrigerant plays a crucial role. The refrigerant is compressed into a high-temperature and high-pressure gas under the action of a compressor, then enters a condenser to be cooled into a high-pressure liquid, then passes through a throttling device to reduce the pressure and becomes a low-temperature and low-pressure gas-liquid mixture, and finally enters an evaporator to evaporate and absorb heat, thereby achieving the refrigeration effect.
[0003] In some large air-conditioning systems, such as central air conditioners or some air conditioners for special purposes, multiple evaporators are often required to meet the refrigeration requirements under different regions or different working conditions. However, when distributing the refrigerant discharged from the compressor to multiple evaporators, if the uniform mixing and reasonable distribution of the refrigerant cannot be achieved, the problem of uneven mixing of the feed in each evaporator will occur. This will cause poor refrigeration effects in some evaporators, while some other evaporators may be over-cooled, which not only affects the overall refrigeration effect and energy efficiency ratio of the air-conditioning system, but also may shorten the service life of the air-conditioning equipment and increase the operation and maintenance costs. Summary of the Invention
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a refrigerant distributor for air conditioners is proposed.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A refrigerant distributor for air conditioners, including a housing, an inlet pipe is movably installed inside the housing, an outlet pipe is fixedly installed on the top of the housing, a plurality of outlet openings are opened at the top of the outlet pipe, a conical pipe is fixedly connected to the top of the inlet pipe, a mixing chamber is fixedly connected to the top of the conical pipe, and the mixing chamber is in mutual contact with the outlet pipe.
[0006] Furthermore: A filter screen is fixedly connected inside the inlet pipe, and an activated carbon filter block is movably installed inside the inlet pipe, and the activated carbon filter block is located above the filter screen.
[0007] Furthermore: A thin pipe is fixedly connected between the conical pipe and the mixing chamber.
[0008] Furthermore: A baffle is fixedly connected inside the mixing chamber, a circular groove is opened at the bottom of the baffle, the circular groove and the thin pipe are on the same central axis, a plurality of discharge holes are opened at the bottom of the baffle, and a discharge hole is opened at the top of the baffle.
[0009] Furthermore, a first external thread is provided on the outer wall of the housing, and a fixing ring is fixedly connected to the outer wall of the feed pipe. A first internal thread corresponding to the first external thread is provided on the inner wall of the fixing ring.
[0010] Furthermore, a second external thread is provided on the outer wall of the top of the housing, and a second internal thread corresponding to the second external thread is provided on the inner wall of the bottom of the discharge pipe. A sealing ring is fixedly installed between the housing and the discharge pipe.
[0011] The utility model has the following beneficial effects:
[0012] Compared with the prior art, by providing a feed pipe, a conical pipe, a thin pipe, a mixing chamber, a circular groove discharge hole, a discharge hole, a discharge pipe and a discharge port, during use, the refrigerant enters the interior of the feed pipe, then passes through the conical pipe, and the refrigerant is compressed by the inner wall shape of the conical pipe, and then enters the mixing chamber through the thin pipe. At this time, when the refrigerant just discharges from the thin pipe, the pressure of the refrigerant will be released, which can play a certain mixing role. After the refrigerant enters the mixing chamber, it directly impacts in the circular groove, and the circular groove can play a role of buffering and mixing. Then the refrigerant enters the interior of the discharge pipe through the discharge hole and the discharge hole. Finally, after the mixed refrigerant enters the discharge pipe, it is discharged into each evaporator through the discharge port, which can ensure that the refrigerant is evenly mixed and reasonably distributed to multiple evaporators, so that each evaporator can exert the best refrigeration performance, thereby improving the refrigeration effect of the air conditioning system as a whole and providing a more comfortable environment for users.

[0020] Refer to Figures 1-5 As shown in the figure, a refrigerant distributor for an air conditioner provided by the utility model includes a housing 1. An inlet pipe 2 is movably installed inside the housing 1. A discharge pipe 3 is fixedly installed on the top of the housing 1. A plurality of discharge ports 301 are opened at the top of the discharge pipe 3. The top of the inlet pipe 2 is fixedly connected to a conical pipe 203. The top of the conical pipe 203 is fixedly connected to a mixing chamber 205. The mixing chamber 205 is in close contact with the discharge pipe 3.
[0021] During use, the inlet pipe 2 is fixedly installed inside the housing 1, the discharge pipe 3 is fixedly installed on the top of the housing 1. Then, the discharge pipe of the compressor is connected to the bottom of the inlet pipe 2, and the inlet pipes of multiple evaporators are connected to the discharge ports 301 at the top of the discharge pipe 3. Next, during use, the refrigerant enters the inside of the inlet pipe 2, then passes through the conical pipe 203, and the refrigerant is compressed by the inner wall shape of the conical pipe 203. Then, the refrigerant enters the mixing chamber 205 for mixing. After mixing is completed, it enters the discharge pipe 3 and is then discharged through the discharge ports 301 into each evaporator.
[0022] A filter screen 201 is fixedly connected inside the inlet pipe 2, and an activated carbon filter block 202 is movably installed inside the inlet pipe 2. The activated carbon filter block 202 is located above the filter screen 201.
[0023] When the refrigerant enters the inside of the inlet pipe 2, first, the filter screen 201 filters out impurities in the refrigerant, and then the activated carbon filter block 202 filters out the odor in the refrigerant.
[0024] A thin pipe 204 is fixedly connected between the conical pipe 203 and the mixing chamber 205.
[0025] When the refrigerant passes through the conical pipe 203, it is compressed and then enters the mixing chamber 205 through the thin pipe 204. At this time, when the refrigerant just exits the thin pipe 204, the pressure of the refrigerant will be released, which can play a certain role in mixing.
[0026] Inside the mixing chamber 205, a stop block 206 is fixedly connected. A circular groove 207 is provided at the bottom of the stop block 206. The circular groove 207 and the thin tube 204 share the same central axis. A plurality of discharge holes 208 are provided at the bottom of the stop block 206, and a discharge hole 209 is provided at the top of the stop block 206.
[0027] When the refrigerant enters the mixing chamber 205, it will impact in the circular groove 207. The circular groove 207 can play a role in buffering and mixing. Then the refrigerant enters the interior of the discharge pipe 3 through the discharge holes 208 and the discharge hole 209.
[0028] The outer wall of the housing 1 is provided with a first external thread 101. A fixing ring 210 is fixedly connected to the outer wall of the feed pipe 2. The inner wall of the fixing ring 210 is provided with a first internal thread 211 corresponding to the first external thread 101.
[0029] During use, the feed pipe 2 can be fixedly installed inside the housing 1 through the cooperation of the first external thread 101 and the first internal thread 211. At the same time, the folded-back shape of the fixing ring 210 can prevent refrigerant leakage.
[0030] The top outer wall of the housing 1 is provided with a second external thread 102. The bottom inner wall of the discharge pipe 3 is provided with a second internal thread 302 corresponding to the second external thread 102. A sealing ring 4 is fixedly installed between the housing 1 and the discharge pipe 3.
[0031] During use, the discharge pipe 3 can be fixedly installed on the top of the housing 1 through the second external thread 102 and the second internal thread 302. At the same time, the sealing ring 4 can play a sealing role to prevent refrigerant leakage.
[0032] Working principle: First, threadedly install the feed pipe 2 inside the housing 1, then place the sealing ring 4 between the housing 1 and the discharge pipe 3, then threadedly install the discharge pipe 3 on the top of the housing 1, then connect the discharge pipe of the compressor to the bottom of the feed pipe 2, and then connect the feed pipes of multiple evaporators to the discharge port 301 at the top of the discharge pipe 3.
[0033] Then during use, the refrigerant enters the interior of the feed pipe 2. First, the filter screen 201 filters out impurities in the refrigerant, then the activated carbon filter block 202 filters out the odor in the refrigerant, then it passes through the conical tube 203, and the refrigerant is compressed by the inner wall shape of the conical tube 203, and then enters the mixing chamber 205 through the thin tube 204. At this time, when the refrigerant just exits the thin tube 204, the pressure of the refrigerant is released, which can play a certain mixing role. After the refrigerant enters the mixing chamber 205, it directly impacts in the circular groove 207. The circular groove 207 can play a role in buffering and mixing. Then the refrigerant enters the interior of the discharge pipe 3 through the discharge holes 208 and the discharge hole 209.
[0034] Finally, the completed refrigerant mixture enters the discharge pipe 3 and then is discharged from each evaporator through the discharge port 301.
