As shown in fig. 1 to 2, the embodiment of the present disclosure provides a refrigeration apparatus including a refrigeration cycle system including an evaporator 2, a compressor 3, a condenser 4, and a throttle device 5, which are sequentially communicated through pipes. Wherein the refrigerant circulates in the evaporator 2, the compressor 3, the condenser 4 and the throttling means 5 to realize the refrigeration of the refrigeration equipment.

When the refrigeration equipment works, the refrigerant evaporates in the evaporator 2 to absorb heat in the air, and the refrigerant becomes a gaseous refrigerant or a gas-liquid two-phase mixed refrigerant. The gaseous refrigerant flows to the compressor 3, and the compressor 3 compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant. The high-temperature high-pressure gaseous refrigerant flows into the condenser 4, and is liquefied and released in the condenser 4, thereby becoming a medium-temperature high-pressure liquid refrigerant or a gas-liquid two-phase mixed refrigerant. The liquid refrigerant with medium temperature and high pressure or the gas-liquid two-phase mixed refrigerant is throttled by the throttling device 5, the liquid refrigerant with medium temperature and high pressure in the throttling device 5 is depressurized into the gas-liquid mixed refrigerant with low temperature and low pressure, and then flows back to the evaporator 2 for evaporation. This completes the refrigeration cycle.

As shown in conjunction with fig. 2-4, embodiments of the present disclosure provide a reservoir 1 for a refrigeration device, the reservoir 1 comprising a housing 10, an inflow tube 20, and an outflow tube 30, the housing 10 defining a reservoir chamber 101; the inflow pipe 20 communicates with the liquid storage chamber 101 so that the gas-liquid mixed refrigerant flows into the liquid storage chamber 101; the outflow pipe 30 communicates with the liquid storage chamber 101 so that the gaseous refrigerant or the liquid refrigerant flows out of the liquid storage chamber 101.

In this embodiment, the mixed refrigerant of gas and liquid phases flows into the liquid storage cavity 101 from the inflow pipe 20, the mixed refrigerant of gas and liquid phases is in the liquid storage 1, and during the use process, the refrigerant in the gas-liquid mixed state enters the liquid storage 1, and the liquid refrigerant which is not vaporized directly falls down to the bottom of the liquid storage 1 because the liquid refrigerant is heavier than gas, so that the gaseous refrigerant and the liquid refrigerant can be separated, and then the gaseous refrigerant or the liquid refrigerant flows out from the outflow port of the liquid storage 1. In this way, the liquid storage device 1 can store unvaporized liquid refrigerant, regulate the amount of the refrigerant participating in the refrigeration cycle at different temperatures, and prevent the phenomenon of liquid impact from generating so that the compressor 3 cannot work normally.

In some alternative embodiments, as shown in fig. 1, the liquid reservoir 1 is adapted to be arranged between the outlet of the evaporator 2 and the inlet of the compressor 3, and the gas-liquid mixed refrigerant flowing out of the evaporator 2 flows into the liquid reservoir 1, wherein the gaseous refrigerant enters the compressor 3 under pressure and the liquid refrigerant falls to the bottom of the liquid reservoir 1 due to gravity.

In this embodiment, during the refrigeration cycle of the refrigeration apparatus, when the evaporator 2 cannot ensure complete vaporization of the liquid refrigerant, when the liquid refrigerant enters the liquid reservoir 1 through the inflow pipe 20, the liquid refrigerant flows to the bottom of the liquid reservoir 1 under the action of gravity, and the gaseous refrigerant enters the compressor 3 through the muffler, so that the compressor 3 cannot work normally due to the phenomenon of "liquid impact" can be prevented.

In other alternative embodiments, as shown in fig. 2, the liquid reservoir 1 is adapted to be located between the outlet of the condenser 4 and the inlet of the evaporator 2, and the refrigerant in a gas-liquid mixture flows out into the liquid reservoir 1 through the condenser 4, wherein the liquid refrigerant falls to the bottom of the liquid reservoir 1 due to gravity, and the liquid refrigerant enters the evaporator 2 along the outflow pipe 30.

In this embodiment, the liquid reservoir 1 is located between the condenser 4 and the evaporator 2, so that the gaseous refrigerant can be prevented from entering the evaporator 2, and the evaporation efficiency of the evaporator 2 can be improved.

It should be noted that: the liquid storage device 1 can be arranged at other positions, can be arranged at different positions according to different use situations, and can be used in different modes.

Optionally, as shown in fig. 3 and 4, the reservoir 1 for a refrigeration device further comprises a porous structure 40, the porous structure 40 being located within the reservoir chamber 101, wherein the porous structure 40 is adapted to absorb noise and/or impurities.

The porous structure 40 in this embodiment can effectively reduce noise generated by the eruption and flow of the refrigerant, and adsorb part of the abrasion residues and solid matters of waste oil of the compressor 3, so as to ensure the silent long-life and efficient operation of the refrigeration equipment. In addition, the porous structure 40 is adopted to reduce noise and remove impurities, so that the installation is simple, and the problem of air tightness does not exist. The porous structure 40 can reduce noise and filter, and has the dual functions of noise reduction and filtering, and compared with the prior art in which a filter screen and a silencing component are respectively arranged, the liquid reservoir 1 provided by the embodiment of the disclosure has the advantages of lower cost, lighter weight and integrated functions.

When the liquid reservoir 1 is positioned between the evaporator 2 and the compressor 3, the porous structure 40 can adsorb abrasion residues and waste oil solid matters of the compressor 3, so that the residues and the waste oil solid matters are prevented from entering the evaporator 2 along with the refrigerant and the lubricating oil through the oil return hole at the lower part of the liquid reservoir 1, and then enter the capillary tube and the compressor 3 to block the capillary tube and influence the normal operation of the compressor 3; the gaseous refrigerant enters the compressor 3 through the outflow pipe 30, the steel wire balls can reduce the eruption flow noise of the refrigerant, and can adsorb the abrasion residues and the waste oil solid matters of the compressor 3 sprayed out along with the refrigerant, so that the abrasion residues and the waste oil solid matters of the compressor 3 are prevented from entering the compressor 3 along with the gaseous refrigerant through the outflow pipe 30, and the operation of the compressor is influenced.

Alternatively, the porous structure 40 includes a metal porous structure or a graphene porous structure. In this embodiment, the porous structure may be made of various materials, and may be formed, and the structure for absorbing noise and/or impurities is an alternative embodiment of the present application.

By way of example, where the porous structure 40 is a metal porous structure, the porous structure may be one or more of wire balls, aluminum foam, copper foam, wire mesh, wire balls, aluminum balls, wire mesh. Likewise, the porous structure may also be a graphene foam porous structure. Alternatively, the porous structure 40 may be a ceramic foam material. The porous structure 40 adopts graphene foam or foam ceramic, so that the mass is light, and the material has the vibration and noise reduction functions, and can absorb noise and impurities better.

For another example, the porous structure 40 may be a porous labyrinth structure, or the porous structure 40 may be an irregular porous structure.

In the embodiment, the porous labyrinth structure has larger pores, so that impurities such as abrasion residues of the shrinking machine, solid matters of waste oil and the like can be absorbed better. The irregular porous structure 40 has a smaller density and higher anti-blocking. Particularly, the foam aluminum type irregular porous structure has lighter weight, and the material has the functions of vibration reduction and noise reduction, and can better absorb noise and impurities.

Optionally, the porous structure 40 comprises steel wire balls.

In the embodiment, the steel wire ball is light in weight, low in cost, easy to obtain and good in noise reduction and impurity absorption effects. Moreover, the steel wire ball is not easy to fall off slag, no extra impurity is added, and the impurity removing effect is better.

Optionally, the wire ball is formed by winding a plurality of helical wires.

In this embodiment, the steel wire ball may have various forms of porous structures. The steel wire ball formed by winding a plurality of spiral steel wires is easy to process and low in cost.

It should be noted that: the wire balls of the present application may also be formed by winding a wire mesh, that is, the form of the wire balls capable of forming a porous shape is an alternative embodiment of the present application.

Optionally, the number of the porous structures 40 is one or more, and when the number of the porous structures 40 is a plurality, the plurality of porous structures 40 are arranged in the liquid storage cavity 101 at intervals.

In this embodiment, the number of the porous structures 40 may be one or more, and in practical application, the user may select to set the number of the porous structures 40 according to the noise condition of the liquid reservoir 1, which is not specifically limited herein.

For example, when the porous structure 40 is a wire ball, the number of wire balls may be 1, 2, 3, 4, etc.

Alternatively, when the number of the porous structures 40 is plural, the types of the plural porous structures 40 may be the same or different. For example, the porous structures 40 may be formed by winding spiral steel wires or other steel wire balls, and the porous structures 40 may be of various types, and the type of the porous structures 40 is selected according to noise and impurity conditions at different positions in the liquid storage cavity 101.

Alternatively, the ratio of the outer diameter of the porous structure 40 to the inner diameter of the reservoir 101 may range from one to ten to two.

In this embodiment, the size of the porous structure 40 can be set according to the inner diameter of the liquid storage cavity 101, and when the ratio of the diameter of the porous structure 40 to the inner diameter of the liquid storage cavity 101 is smaller than one to ten, the size of the porous structure 40 is too small to facilitate the setting of the porous structure 40. When the ratio of the diameter of the porous structure 40 to the inner diameter of the liquid storage chamber 101 is greater than one to two, the size of the porous structure 40 is too large, which is inconvenient for taking and placing the porous structure 40, and affects the storage volume of the liquid storage device 1.

It should be noted that: the inner diameter of the liquid storage chamber 101 herein refers to the inner diameter of the cross section of the liquid storage chamber 101, and the diameter of the porous structure 40 refers to the longest outer diameter of the porous structure 40.

By way of example, the ratio of the diameter of the porous structure 40 to the inner diameter of the reservoir 101 may be 1/8, 1/6, 1/5, 1/3, etc.

Optionally, the porous structure 40 is provided at one or more of the top of the reservoir 101, the bottom of the reservoir 101, and the middle of the reservoir 101.

In this embodiment, the porous structure 40 may be disposed at any position of the liquid storage cavity 101, and when installed at the bottom of the liquid storage cavity 101, not only can reduce noise, but also can adsorb impurities such as abrasion residues of the compressor 3 and solid matters of waste oil in the liquid refrigerant, so as to avoid the impurities flowing out of the liquid storage device 1 to block the pipeline or other components.

Alternatively, the porous structure 40 corresponds to an outlet of the outflow pipe 30 to reduce noise generated by the outflow of the refrigerant from the outflow pipe 30.

For example, as shown in fig. 1, when the accumulator 1 is disposed between the evaporator 2 and the compressor 3, the inflow pipe 20 communicates with the bottom of the accumulator 1, the outflow pipe 30 communicates with the top of the accumulator 1, and the refrigerant mixed with the gas and the liquid is sprayed from the inflow pipe 20 into the liquid storage chamber 101, wherein the liquid refrigerant falls down to the bottom of the liquid storage chamber 101 by gravity. The number of the porous structures 40 is three, wherein two porous structures 40 are arranged at the bottom of the liquid storage cavity 101, and one porous structure 40 is arranged at the top of the liquid storage device 1. The porous structure 40 at the bottom is capable of adsorbing noise while adsorbing residues or oil residues or the like carried by the liquid refrigerant. The porous structure 40 at the top faces or faces the inflow tube 20 side by side for reducing noise generated when the refrigerant is ejected out of the inflow tube 20.

As shown in fig. 2, when the accumulator 1 is disposed between the condenser 4 and the evaporator 2, the inflow pipe 20 and the outflow pipe 30 are both in communication with the top of the accumulator 1, wherein the liquid refrigerant is stored in the liquid storage chamber 101, the lower end of the inflow pipe 20 is located above the liquid level of the liquid refrigerant, the lower end of the outflow pipe 30 is located below the liquid level of the liquid refrigerant, the gas-liquid mixed refrigerant flows into the liquid storage chamber 101 from the inflow pipe 20, and the liquid refrigerant flows out from the outflow pipe 30.

As shown in fig. 4, the number of the porous structures 40 is plural, the porous structures 40 are all located at the bottom of the liquid storage cavity 101, specifically, the number of the porous structures 40 may be three, and the three porous structures 40 are arranged at the bottom of the liquid storage cavity 101 at intervals and below the liquid level of the liquid refrigerant, so that the porous structures 40 can reduce the flowing noise of the liquid refrigerant, and can adsorb the abrasion residues and the solid waste oil substances of the compressor, so as to prevent the residues and the solid waste oil substances from flowing along with the refrigerant, thereby causing pipeline blockage or affecting the normal operation of the compressor.

Optionally, the porous structure 40 is fixedly connected to the housing 10.

In this embodiment, the porous structure 40 is fixedly connected to the housing 10, that is, the porous structure 40 is fixedly connected to the wall of the liquid storage chamber 101, so that the fixing stability of the porous structure 40 can be increased. The porous structure 40 is prevented from moving or misplacing in the transportation, carrying and installation processes of the liquid reservoir 1, and the noise reduction effect is prevented from being influenced.

By way of example, the porous structure 40 may be attached to the reservoir 1 by laser welding, high frequency induction welding, or the like. Here, the connection of the porous structure 40 is more stable by adopting a welding mode, the porous structure 40 is not easy to fall off, and the operation stability of the refrigeration equipment is improved.

Optionally, the porous structure 40 abuts the housing 10.

In this embodiment, the porous structure 40 is abutted to the housing 10, which means that the porous structure 40 can be freely placed in the liquid storage cavity 101, that is, the porous structure 40 is placed in the liquid storage cavity 101 under the self-gravity, and the porous structure 40 is not contacted with the housing 10, so that the porous structure 40 is convenient to set, install and detach. The porous structure 40 may be installed in a post-loading manner with respect to the existing reservoir 1.

In practical applications, when the number of the porous structures 40 is plural, the plural porous structures 40 may be disposed in the liquid storage cavity in different manners, for example, may be disposed in a manner of combining fixed connection and free placement.

Alternatively, the shape of the porous structure 40 may be various, for example, the porous structure 40 may be ellipsoidal, spherical, cylindrical, conical, or the like. The shape of the porous structure 40 may be set according to the shape of the reservoir, and is not particularly limited herein.

In practical application, the porous structure 40 is embedded in the liquid storage device 1 of the refrigeration equipment, and can adsorb residues and waste oil solid matters generated by abrasion of the compressor 3 in the liquid storage device 1, so that oil return of the lubricating oil of the compressor 3 is not influenced, the residues and the waste oil solid matters are prevented from blocking capillaries or influencing the operation of the compressor 3, and the refrigeration efficiency of the long-term operation of the compressor 3 is ensured not to be attenuated.

It should be noted that: the reservoir 1 is not limited to the two forms according to the embodiments of the present disclosure, and the installation position and the use principle of the reservoir 1 are different according to the use scenario.
