The embodiment of the application provides a gas-liquid separator.
Referring to fig. 1, in an embodiment, the gas-liquid separator 100 includes a tank 110, an inlet pipe 120, an outlet pipe 130, and a filtering assembly 140. Wherein, the tank 110 has a gas-liquid separation chamber 111; one end of the inlet pipe 120 extends into the gas-liquid separation chamber 111, and the other end of the inlet pipe 120 is used for connecting an evaporator (not shown) of an air conditioner (not shown); one end of the air return pipe 130 is arranged in the gas-liquid separation cavity 111, and the other end of the air return pipe 130 extends out of the gas-liquid separation cavity 111 and then is connected with an external compressor 200; the filter assembly 140 is disposed in the gas-liquid separation chamber 111 and is fixedly connected to the muffler 130, and covers the air inlet of the muffler 130.
It should be noted that, in the present embodiment, the present gas-liquid separator 100 is mainly used in an air conditioner, but the technical solution of the present application may be applied to other refrigeration systems with suitable structures. Taking an air conditioner as an example, a compressor is one of the most central components of the air conditioner, however, in actual operation, the reasons for the damage of the compressor 200 generally include liquid slugging caused by the suction of liquid refrigerant, and damage to the compressor 200 caused by the solid impurities contained in the gas entering the compressor 200. The liquid impact problem can be solved by connecting the gas-liquid separator 100, but the problem of impurities cannot be solved by adding the gas-liquid separator 100, and the gas-liquid separator 100 may also become a new source of impurities, for example, in addition to impurities entering the gas-liquid separator 100 through the inlet pipe 120, the gas-liquid separator 100 may generate scale during welding, and impurities such as welding slag may be formed after the scale is removed, and in addition, the refrigerant filled into the gas-liquid separator 100 during market maintenance and the filling equipment may also contain impurities. To address the problem of impurities, a common solution in the industry is to add a filter to the return pipe 130 connecting the gas-liquid separator 100 and the compressor 200. However, this way of adding filters causes various disadvantages of increasing the number of craters, increasing the number of parts, and increasing the cost.
In this embodiment, compared with the conventional method of adding a filter to the muffler 130 connected to the gas-liquid separator 100 and the compressor 200, in this application, the filter assembly 140 is embedded in the gas-liquid separation chamber 111 and is fixedly connected to the muffler 130, and covers the air inlet of the muffler 130, so that the filter can be prevented from being welded to the muffler 130 between the gas-liquid separator 100 and the compressor 200, the entire muffler 130 does not need to be disconnected, the number of welded junctions can be effectively reduced, the number of parts can be reduced, the cost is greatly reduced, and the efficiency of the compressor 200 can be improved due to the effective filtration of impurities. In addition, in actual operation, the impurities entering the gas-liquid separator 100 through the gas inlet pipe 120 may enter the gas return pipe 130 through the gas inlet of the gas return pipe 130 under the gas-liquid agitation, and the speed of the impurities is usually fast, and if the filter is disposed on the gas return pipe 130 between the gas-liquid separator 100 and the compressor 200, the impurities are easily broken through the filter and enter the compressor 200 to damage the compressor 200. However, in the present application, since the filter assembly 140 covers the air inlet of the air return pipe 130, the impurities are not easy to enter the air return pipe 130, and the damage of the impurities to the compressor 200 can be effectively reduced.
Referring to fig. 2, in the embodiment, the filter assembly 140 includes a filter screen 141 and a support bracket 142, the support bracket 142 is fixed to the air inlet of the muffler 130, and the filter screen 141 is attached to the support bracket 142 and covers the air inlet. It can be understood that the filter assembly 140 is disposed in the gas-liquid separator 100 and thus is subjected to a certain air flow impact, and the filter screen 141 itself is soft, so that the filter screen 141 can be effectively prevented from being deformed due to the air flow impact only after the strength of the filter screen is increased by the effective support of the support bracket 142. Moreover, the effective filtering area of the filter screen 141 can be increased by the opening function of the supporting bracket 142, so that the filtering effect is improved and the service life is prolonged.
Further, in the present embodiment, the supporting bracket 142 is lined on the inner side of the filter screen 141. Of course, in other embodiments, the filter screen 141 may be attached to the inner side of the supporting bracket 142 under the condition that the filter screen 141 and the supporting bracket 142 are firmly connected. However, in this embodiment, since the gas flows from the gas-liquid separation chamber 111 into the inlet of the muffler 130, that is, the gas flow enters from the outside of the filter screen 141 to the inside, the support frame 142 is lined inside the filter screen 141, which not only can effectively support the filter screen 141 and disperse the pressure generated by the impact of the gas flow, but also can effectively prevent the filter screen 141 from sinking into the inner side of the support frame 142 due to the loose connection and even blocking the inlet of the muffler 130 when the filter screen 141 is attached to the inside of the support frame 142.
Specifically, in this embodiment, the supporting frame 142 is a metal spring net, a cross-shaped supporting frame, or a hollow cage-shaped frame. Of course, the supporting bracket 142 may be made of other suitable materials and designed in a shape, as long as the conditions that the filtering net 141 can be effectively supported, the gas-liquid separator 100 is suitable, and new contaminant impurities are not generated are satisfied, which is not limited herein.
Further, as shown in fig. 2, in the present embodiment, the filter screen 141 is tapered from the connection with the muffler 130 to a direction away from the air inlet of the muffler 130. Therefore, the airflow pressure on the filter screen 141 can be better adapted to the actual airflow direction, the airflow pressure on the filter screen 141 is effectively reduced, and the filtering area of the filter screen 141 is increased.
It should be noted that, in order to enhance the connection between the filter element 140 and the air inlet of the air return pipe 130, in this embodiment, the filter element 140 is preferably connected to the air inlet of the air return pipe 130 in an interference fit manner. However, the design is not limited thereto, and in other embodiments, the filter element 140 may be riveted or welded to the air inlet of the muffler 130, and of course, other manners that can firmly connect the filter element 140 to the muffler 130 may also be adopted.
Referring to fig. 1, in the present embodiment, the gas inlet pipe 120 is provided with a gas outlet at a free end of the gas-liquid separation chamber 111, a pipe section of the gas inlet pipe 120 extending into the gas-liquid separation chamber 111 is L-shaped, and the gas inlet pipe 120 is bent toward an inner side wall of the gas-liquid separation chamber 111, so that liquid can be prevented from entering the gas return pipe 130 when the gas outlet of the gas inlet pipe 120 is opposite to a gas inlet of the gas return pipe 130, and the arrangement has a certain liquid return prevention function. Further, in the present embodiment, the air outlet is lower than the filter assembly 140, so that the liquid return prevention effect can be further improved and the filter screen 141 can be prevented from being washed and deformed by the air flow at the air outlet of the air inlet pipe 120.
The present invention further provides an air conditioner, which includes a compressor 200 and a gas-liquid separator 100, the compressor is connected to the gas-liquid separator 100 through a gas return pipe 130, the specific structure of the gas-liquid separator 100 refers to the above embodiments, and since the air conditioner employs all technical solutions of all the above embodiments, the air conditioner also has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
