[0003] In the current gas-liquid separator, by utilizing the density difference between gas and liquid, the gas is separated from the liquid under the action of gravity, and the separation effect is good. However, after the refrigerant evaporates into gas, it may contain moisture. When the refrigerant circulates in the refrigeration system, moisture may be mixed in due to the imperfect system or improper operation. These moisture still exist after the refrigerant evaporates into gas, and the current gas-liquid separator is difficult to remove this moisture. Content of the Utility Model

Detailed Embodiment

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-6 , a parallel gas-liquid separator for an outdoor unit of a heat recovery air conditioner provided by the present utility model includes: a separation tank 1, an intake pipe 2 connected to the inner wall on one side of the separation tank 1, and a liquid outlet pipe 3 connected to the inner wall at the bottom of the separation tank 1. It further includes: a separation component 6 installed on the inner wall at the top of the separation tank 1, a communication pipe 4 connected to the inner wall on one side of the separation component 6, and a drying tank 5 connected to one end of the communication pipe 4. Two support rods 7 are fixed to the inner wall at the bottom of the separation tank 1, and the tops of the two support rods 7 are fixed with the same liquid distribution plate 8. A gas extraction component 9 is rotatably installed on the outer wall at the top of the separation tank 1, and a drying component 10 is rotatably installed on the outer wall at the top of the drying tank 5. A bending plate 11 is installed on the outer wall of the communication pipe 4, and a motor 12 is installed on the inner wall at the top of the bending plate 11. A transmission component 13 is installed on the output shaft of the motor 12, and the output shaft of the motor 12 is in transmission connection with the gas extraction component 9 and the drying component 10 through the transmission component 13. An exhaust pipe 14 is connected to the inner wall at the bottom of the drying tank 5.

[0022] It should be noted here that: the gas-liquid mixture can enter the separation tank 1 through the intake pipe 2. The separation component 6 forces the gas to perform a centrifugal swirling motion to generate a centrifugal force, so that the liquid with a larger density is thrown to the surroundings and flows downward, thereby achieving the effect of gas-liquid separation. Under the action of the transmission component 13 by the motor 12, the gas extraction component 9 and the drying component 10 can be driven to rotate simultaneously. After the gas-liquid separation, the gas enters the separation component 6, and the liquid flows to the bottom inside the separation tank 1 and is discharged through the liquid outlet pipe 3. The rotation of the gas extraction component 9 can accelerate the gas flow rate, enabling the gas to enter the drying tank 5 through the communication pipe 4 faster. After the gas is dried by the drying component 10 when entering the drying tank 5, it is then discharged through the exhaust pipe 14. By arranging the separation component 6 and the drying component 10 in parallel connection, after gas-liquid separation of the gas, the moisture in the gas can be removed immediately to avoid affecting the refrigeration effect. The drying component 10 is of an annular structure with a large drying area and rotates continuously during the drying process, enabling the effective utilization of the drying area on the drying component 10 and eliminating the need to replace the desiccant for a long time.

[0023] In a preferred embodiment, the separation component 6 includes a guiding pipe 602 and a plurality of equally spaced spiral vanes 601 fixed to the outer wall of the guiding pipe 602.

[0024] It should be noted here that the gas-liquid mixture enters the intake pipe 2 and, under the guidance of the spiral blade 601, makes a centrifugal swirling motion to generate a centrifugal force, causing the liquid with a larger density to be thrown to the surroundings and flow downward, thereby achieving the effect of gas-liquid separation. Finally, the gas enters the guiding pipe 602 upward.

[0025] In a preferred embodiment, the air extraction assembly 9 includes a long shaft 901 and a fan blade 902 fixed to the bottom of the long shaft 901.

[0026] It should be noted here that when the motor 12 rotates, it can drive the long shaft 901 to rotate through the transmission assembly 13, and then drive the fan blade 902 to rotate, which can accelerate the gas flow rate and make the gas pass through the connecting pipe 4 and enter the drying tank 5 faster.

[0027] In a preferred embodiment, the drying assembly 10 includes a short shaft 1001, a mounting frame 1002 fixed to the bottom of the short shaft 1001, a mesh box 1003 fixed to the outer wall of the mounting frame 1002, and a desiccant placed in the mesh box 1003.

[0028] It should be noted here that the gas entering the drying tank 5 can be adsorbed by the desiccant in the mesh box 1003 and then discharged through the exhaust pipe 14. By setting the annular mesh box 1003, the drying area can be maximized. When the motor 12 rotates, it can drive the short shaft 1001 to rotate through the transmission assembly 13, and then drive the mesh box 1003 to rotate, so that the desiccant in the mesh box 1003 can be effectively utilized and the desiccant does not need to be replaced for a long time.

[0029] In a preferred embodiment, the transmission assembly 13 includes a driving wheel 1301 fixed to the output shaft of the motor 12, a driven wheel 1302 fixed to the short shaft 1001 and the long shaft 901, and two belts 1303 connected to the driving wheel 1301. The two belts 1303 are respectively connected to the two driven wheels 1302 at the ends away from each other.

[0030] It should be noted here that the motor 12 can drive the driving wheel 1301 to rotate, drive the two belts 1303 to rotate, and then drive the two driven wheels 1302 to rotate, and then drive the short shaft 1001 and the long shaft 901 to rotate.

[0031] Working principle: The gas-liquid mixture can enter the separation tank 1 through the intake pipe 2. Under the guidance of the spiral blade 601, it makes a centrifugal swirling motion to generate centrifugal force, causing the liquid with a larger density to be thrown to the surroundings and flow downward, thus achieving the effect of gas-liquid separation. Finally, the gas enters the guide pipe 602 upward. The motor 12 can drive the driving wheel 1301 to rotate, drive the two belts 1303 to rotate, and then drive the two driven wheels 1302 to rotate, and then drive the short shaft 1001 and the long shaft 901 to rotate. When the long shaft 901 rotates, it drives the fan blade 902 to rotate, which can accelerate the gas flow rate, enabling the gas to pass through the connecting pipe 4 and enter the drying tank 5 faster. The gas entering the drying tank 5 can be adsorbed by the desiccant in the wire mesh box 1003 and then discharged through the exhaust pipe 14. By setting the annular wire mesh box 1003, the drying area can be maximized. When the motor 12 rotates, it can drive the short shaft 1001 to rotate through the transmission component 13, and then drive the wire mesh box 1003 to rotate, enabling the desiccant in the wire mesh box 1003 to be effectively utilized, and the desiccant does not need to be replaced for a long time. By arranging the separation component 6 and the drying component 10 side by side, after gas-liquid separation of the gas, the moisture in the gas can be removed immediately to avoid affecting the refrigeration effect.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
