For example, as shown in fig. 3, the inlet 310 of the liquid trap 300 is arranged along the tangential direction of the arc-shaped portion 351, so that the first medium entering the inner cavity 350 of the liquid trap 300 along the inlet 310 tangentially contacts the surface of the arc-shaped portion 351, so that the first medium can efficiently form a vortex under the flow guiding effect of the arc-shaped portion 351 to play a role similar to a "vortex separator", thereby efficiently performing gas-liquid separation, reducing the gas content in the first medium, improving the heat conductivity of the first medium, and enhancing the heat exchange capability of the first medium.
For another example, as shown in fig. 3, the outlet 320 of the liquid collector 300 is arranged along the tangential direction of the arc-shaped portion 351, so that the first medium after being guided by the arc of the arc-shaped portion 351 can be thrown out from the outlet 320 along the tangential direction of the arc-shaped portion 351 under the action of inertia, the vortex forming effect can be further enhanced, the gas-liquid separation efficiency is improved, the liquid drainage efficiency of the liquid collector 300 is higher due to the design, the gas can be prevented from being dissolved again, the gas content in the first medium is further reduced, the heat conductivity of the first medium is improved, and the heat exchange capacity of the first medium is enhanced.

Example 3:
as shown in fig. 4, in addition to the features of the above embodiment, the present embodiment further defines: the outlet 320 of the liquid trap 300 is located lower than the inlet 310 of the liquid trap 300.
It should be noted that, when the product is placed on a supporting surface such as the ground, a table, etc. for use, the central line or center of the outlet 320 is lower than the central line or center of the inlet 310 in a direction perpendicular to the supporting surface.

Therefore, the probability of gas re-melting into liquid can be reduced, the gas content in the first medium is further reduced, the heat conductivity of the first medium is improved, and the heat exchange capacity of the first medium is enhanced.
Of course, the present invention is not limited to this, and in other embodiments, the skilled person may also design the position of the outlet 320 to be flush with the position of the inlet 310, or the position of the center line of the inlet 310 to be at the same level as the position of the center line of the outlet 320, according to the requirement.

A first medium flows through the first medium circuit 100, a second medium flows through the second medium circuit 400, and the first medium and the second medium may be the same medium or different media.
Further, a pump 200 is provided in the first medium circuit 100 for driving the first medium to flow.
Further, the first heat exchanger 110 is provided with a first fan 111 for driving the air flow to exchange heat therewith. The second heat exchanger 420 is provided with a second fan 421 for driving the air flow to exchange heat therewith.
For example, the first medium is water or other coolant.
For example, the second medium is a refrigerant.
For example, the energy storage material is water.
When the cold storage mode is operated, in the second medium loop 400, a second medium enters the compressor 410, after the compressor 410 compresses the second medium, the second medium is sent to the second heat exchanger 420, the second medium exchanges heat with the environment through the second heat exchanger 420 in the second heat exchanger 420 to realize condensation, the condensed second medium enters the throttling device 430 to be throttled, then the throttled second medium enters the second flow path 440 of the energy storage device 120 to be evaporated, wherein cold energy released by evaporation is stored in the energy storage material 123, and finally, the evaporated second medium returns to the compressor 410 to realize circulation.
In the cooling mode, in the first medium circuit 100, the first medium releases heat to the energy storage material 123 in the first flow path 122 of the energy storage device 120, the first medium after heat release enters the first heat exchanger 110, and absorbs heat of the environment through the first heat exchanger 110 in the first heat exchanger 110, so that cooling of the environment is realized, and the first medium after heat absorption returns to the first flow path 122 of the energy storage device 120 again to release heat, thereby completing a cycle.
On the contrary, when the heat storage mode is operated, in the second medium circuit 400, the second medium discharged from the compressor 410 enters the second flow path 440 of the energy storage device 120, so that the second medium releases heat to the energy storage material 123 through the second flow path 440, so that the energy storage material 123 absorbs heat and stores the heat, accordingly, the second medium is condensed through heat release, the condensed second medium enters the throttling device 430 for throttling treatment, then, the throttled second medium enters the second heat exchanger 420 for evaporation, wherein the cold released by evaporation is released to the environment, and finally, the evaporated second medium returns to the compressor 410 to realize circulation.
In the heating mode, in the first medium circuit 100, the first medium absorbs heat from the energy storage material 123 in the first flow path 122 of the energy storage device 120, the first medium after absorbing heat enters the first heat exchanger 110, and releases heat to the environment through the first heat exchanger 110 in the first heat exchanger 110, so that heat is supplied to the environment, and the first medium after releasing heat returns to the first flow path 122 of the energy storage device 120 again to absorb heat, thereby completing the cycle.
For example, as shown in fig. 3, a four-way valve 460 is provided in the second medium circuit 400, and the cold storage mode and the heat storage mode can be switched by the four-way valve 460. Of course, the air conditioning system may not be provided with the four-way valve 460 according to the specific demand.
Here, by providing the liquid trap 300 in the first medium circuit 100 and positioning the outlet 320 of the liquid trap 300 higher than the liquid suction port 210 of the pump 200, bubbles in the first medium circuit 100 can rise along the pipe of the first medium circuit 100 due to a gas-liquid density difference when the first medium circuit 100 stops standing, and thus are collected in the liquid trap 300.
The accumulator 300 is provided with an inlet 310, an outlet 320 and a fill port 330. The fill port 330 can facilitate filling of the first medium into the first medium circuit 100. The fill port 330 is sealed with a rubber cap, the top of which can deform to counteract pressure fluctuations in the first medium circuit 100 caused in part by the start and stop operation of the pump 200 of the first medium circuit 100.
The inlet 310 and the outlet 320 of the liquid collector 300 are tangent to the wall surface of the liquid collector 300, and a vortex is formed in the liquid collector 300 in the circulation process of the first medium, so that the function similar to that of a vortex separator is achieved, bubbles contained in the first medium are separated, the gas content in the first medium is reduced, the heat conductivity of the first medium is improved, and the heat exchange capacity of the first medium is enhanced.
The position of the pump 200 in the first medium circuit 100 is located above the energy storage device 120, below the outlet 320 of the liquid trap 300, the first medium in the liquid trap 300 is pumped into the first flow path 122 of the energy storage device 120 through the pump 200 to exchange heat with the energy storage material, the first medium with a lower temperature directly enters the first heat exchanger 110 to exchange heat with the external environment after coming out of the first flow path 122 of the energy storage device 120, and the first medium with a higher temperature after absorbing heat flows into the liquid trap 300. It is worth mentioning that the first medium cannot pass through the pump 200 after entering the energy storage device 120 for cooling, so as to prevent the cryogenic fluid from passing through the pump 200 and causing the problem of surface condensation of the pump 200.
