Description

Technical Field

[0001] The present application relates to the technical field of refrigeration systems, and in particular to a heat recovery liquid storage device and a refrigeration system. Background Art

[0002] In the refrigeration system, the liquid receiver plays the role of supplying liquid to the evaporator of the cold storage in the system, ensuring that the evaporator of the cold storage can obtain sufficient refrigerant liquid to absorb heat through evaporation, and maintain the cold storage environment at a suitable temperature. The regenerator is generally connected between the compressor and the evaporator through an engineering pipeline, and the saturated refrigerant gas from the evaporator after evaporation and heat absorption is reheated and heat exchanged again to ensure its superheat, thereby ensuring that the refrigerant entering the compressor suction port is fully gaseous and saturated, preventing the risk of compressor liquid shock.

[0003] In the existing refrigeration system, the liquid receiver and the heat regenerator are two independent devices. To ensure the stable operation of the refrigeration system, the heat regenerator and the liquid receiver are usually connected to the relevant refrigeration equipment through cumbersome engineering pipelines and valves installed on-site to form a complete refrigeration system. How to simplify the cumbersome process of on-site installation is a problem to be solved. Utility Model Content

[0008] The regenerator comprises a regenerator body, an air inlet pipe and an air outlet pipe. The regenerator body is arranged in the accommodating cavity and connected to the cylinder. The air inlet pipe and the air outlet pipe are respectively connected and communicated with the regenerator body. Along the radial direction of the cylinder, the air inlet pipe and the air outlet pipe are respectively arranged to pass through the cylinder.

[0009] It can be understood that the heat regenerator is arranged in the accommodating cavity, so that the cylinder and the heat regenerator are highly integrated, the on-site installation process of the cylinder and the heat regenerator is simplified, the workload of on-site construction is reduced, and welding quality problems caused by uneven welding technology levels of different on-site construction personnel are avoided. At the same time, the air inlet pipe and the air outlet pipe are respectively arranged to pass through the cylinder along the radial direction of the cylinder, so that the liquid refrigerant in the accommodating cavity can immerse the heat regenerator body, the air inlet pipe and the air outlet pipe at the same time, thereby improving the heat exchange effect of the heat regenerator, meeting the use requirements of the heat recovery liquid storage device, and ensuring the normal use of the refrigeration system.

[0010] In one embodiment, the height of the cylinder is set to H, the height of the regenerator body is set to A, the height of the air inlet pipe on the cylinder is set to B, and the height of the air outlet pipe on the cylinder is set to C, wherein 2A≤H, 3B≤H, and 3C≤H.

[0011] It is understandable that when the heat recovery liquid storage device is working, the liquid level height in the containing chamber usually exceeds half of the height of the cylinder. Therefore, under the conditions of 2A≤H, 3B≤H, 3C≤H, ensuring that the heat recovery device body, the air inlet pipe and the air outlet pipe are completely immersed in the liquid refrigerant in the containing chamber is beneficial to improving the heat exchange effect.

[0012] In one embodiment, the regenerator is disposed at the bottom of the cylinder.

[0013] It can be understood that the heat regenerator is arranged at the bottom of the cylinder so that the heat regenerator is located at the bottom of the accommodating cavity, which further ensures that the heat regenerator body, the air inlet pipe and the air outlet pipe are completely immersed in the liquid refrigerant, which is beneficial to improving the heat exchange effect.

[0014] In one of the embodiments, the heat regenerator further comprises a mounting seat, the heat regenerator body is mounted on the mounting seat, and the mounting seat is connected to the bottom of the cylinder.

[0015] It can be understood that the heat regenerator body is fixed to the bottom of the cylinder through a mounting base to facilitate stable installation.

[0016] In one embodiment, the height of the cylinder is set to H, and the height of the liquid outlet on the cylinder is set to D, wherein (3 / 4)H≤D≤(4 / 5)H, and the liquid supply port is arranged close to the bottom of the cylinder.

[0017] In one embodiment, the height of the air outlet pipe on the cylinder is set to C, and the height of the liquid supply port on the cylinder is set to E, wherein E<C.

[0019] In one embodiment, the heat recovery liquid storage device also includes an air inlet external pipe and an air outlet external pipe. The air inlet external pipe is arranged outside the cylinder and is connected and communicated with the air inlet pipe. The air outlet external pipe is arranged outside the cylinder and is connected and communicated with the air outlet pipe.

[0020] It is understandable that the air inlet external pipe is connected and communicated with the air inlet pipe, and the air outlet external pipe is connected and communicated with the air outlet pipe to facilitate installation operation.

[0021] In one embodiment, the liquid drop port and the air inlet pipe are arranged on the same side of the cylinder, and the air outlet pipe and the liquid supply port are arranged on the other side of the cylinder.

[0022] It is understandable that the liquid drop port and the air inlet pipe are arranged on the same side of the cylinder body for easy installation.

[0023] In one embodiment, a vent is further provided on the cylinder 11 , and the vent is arranged at the top of the cylinder along the axial direction of the cylinder, and the vent is arranged higher than the liquid drop port.

[0024] It is understandable that by providing a vent on the cylinder, a closed space is avoided in the cylinder, and the air pressure in the accommodating chamber is balanced with that outside the cylinder, which is conducive to the liquid refrigerant to smoothly enter the accommodating chamber from the liquid outlet.

[0025] This application also provides the following technical solutions:

[0027] It is understandable that the refrigeration system using the above-mentioned heat recovery liquid receiver has lower construction difficulty, improves system installation efficiency and heat exchange effect, and ensures stable operation of the compressor to avoid the risk of liquid hammer.

[0028] Due to the application of the above solution, the present application has the following advantages compared with the prior art:

[0029] The heat regenerator and refrigeration system for which protection is sought in the present application, by arranging the heat regenerator in the accommodating cavity, makes the cylinder and the heat regenerator highly integrated, simplifies the on-site installation process of the cylinder and the heat regenerator, reduces the workload of on-site construction, and avoids welding quality problems caused by uneven welding process levels of different on-site construction personnel. At the same time, the heat regenerator body, the air inlet pipe and the air outlet pipe can all exchange heat with the liquid refrigerant in the accommodating cavity, thereby improving the heat exchange effect and meeting the use requirements of the cylinder and the heat regenerator.

[0039] The heat recovery liquid storage device 100 for which protection is sought in the present application is applied in a refrigeration system, and in particular in a high-pressure liquid storage device.

[0040] See also Figure 1A regenerative liquid storage device 100 provided in one embodiment of the present application includes a cylinder 11 and a regenerator 20. The cylinder 11 is provided with a liquid drop port 111 and a liquid supply port 112. The cylinder 11 has a receiving cavity 12. The liquid drop port 111 and the liquid supply port 112 are connected through the receiving cavity 12. In the axial direction of the cylinder 11, the liquid drop port 111 is arranged higher than the liquid supply port 112. The liquid drop port 111 is used to connect to the condenser, and the liquid supply port 112 is used to connect to the throttling element. The liquid refrigerant introduced by the liquid drop port 111 can pass through the receiving cavity 12 and be discharged from the liquid supply port 112.

[0041] The regenerator 20 includes a regenerator body 21, an air inlet pipe 22 and an air outlet pipe 23. The regenerator body 21 is arranged in the accommodating cavity 12 and connected to the cylinder 11. The air inlet pipe 22 and the air outlet pipe 23 are respectively connected and communicated with the regenerator body 21. Along the radial direction of the cylinder 11, the air inlet pipe 22 and the air outlet pipe 23 are respectively arranged to pass through the cylinder 11.

[0042] In this way, the cylinder 11 of the regenerative heat storage device 100 is highly integrated with the regenerative heat storage device 20, which simplifies the on-site installation process of the regenerative heat storage device 100, reduces the workload of on-site construction, and avoids welding quality problems such as welding failure of welding pipes and refrigerant leakage caused by uneven welding process levels of different construction personnel on site. At the same time, the air inlet pipe 22 and the air outlet pipe 23 are respectively arranged to pass through the cylinder 11 along the radial direction of the cylinder 11, and the regenerative heat storage device 20 can exchange heat with the liquid refrigerant in the accommodating chamber 12, so that the liquid refrigerant in the accommodating chamber 12 can simultaneously immerse the regenerative heat storage device body 21, the air inlet pipe 22 and the air outlet pipe 23, thereby improving the heat exchange effect of the regenerative heat storage device 20 and meeting the use requirements of the regenerative heat storage device 100. Among them, the air inlet pipe 22 is used to connect the cold storage return air pipeline, and the air outlet pipe 23 is used to connect the compressor.

[0043] In this embodiment, the gaseous refrigerant introduced into the air inlet pipe 22 can flow through the regenerator body 21 and be led out from the air inlet pipe 22, and in the working state, the regenerator 20, the air inlet pipe 22 and the air outlet pipe 23 are all immersed in the liquid refrigerant in the accommodating chamber 12. Among them, the temperature of the liquid refrigerant introduced into the liquid drop port 111 is greater than the temperature of the gaseous refrigerant introduced into the air inlet pipe 22, so as to realize the heat exchange between the regenerator 20 and the liquid refrigerant in the accommodating chamber 12. In this way, the gaseous refrigerant led out from the air outlet pipe 23 and transported to the compressor has a certain degree of superheat, ensuring the smooth operation of the compressor and avoiding the risk of compressor liquid hammer, and the liquid refrigerant led out from the liquid supply port 112 has a certain degree of subcooling.

[0044] like Figure 2As shown, in one embodiment, the cylinder 11 is roughly cylindrical, the height of the cylinder 11 is set to H, the height of the regenerator body 21 is set to A, the height of the air inlet pipe 22 on the cylinder is set to B, and the height of the air outlet pipe 23 on the cylinder is set to C, wherein 2A≤H, 3B≤H, 3C≤H. Since the liquid level of the liquid refrigerant in the accommodating chamber 12 is usually more than half of the height of the cylinder 11 when the regenerator 100 is working, therefore, under the condition of satisfying 2A≤H, 3B≤H, 3C≤H, it is ensured that the regenerator body 21, the air inlet pipe 22 and the air outlet pipe 23 are completely immersed in the liquid refrigerant in the accommodating chamber 12, which is conducive to improving the heat exchange effect. If the installation height of the regenerator 20 is too high, it may cause the regenerator 20 to be unable to be completely immersed in the liquid refrigerant as the liquid level in the accommodating chamber 12 fluctuates, resulting in poor heat exchange effect.

[0045] like Figure 2 As shown, in one embodiment, the height of the barrel 11 is set to H, the height of the liquid outlet 111 on the barrel 11 is set to D, wherein (3 / 4)H≤D≤(4 / 5)H, and the liquid supply port 112 is arranged close to the bottom of the barrel 11. Under the condition that (3 / 4)H≤D≤(4 / 5)H is satisfied, the liquid outlet 111 has a sufficient height to meet the use requirements.

[0046] like Figure 1 As shown, in one embodiment, the liquid drop port 111 and the air inlet pipe 22 are arranged on the same side of the cylinder 11, and the air outlet pipe 23 and the liquid supply port 112 are arranged on the other side of the cylinder 11 for easy installation.

[0047] like Figure 2 As shown, in one embodiment, the height of the gas outlet pipe 23 on the cylinder 11 is set to C, and the height of the liquid supply port 112 on the cylinder 11 is set to E, where E<C. That is, the liquid supply port 112 is arranged below the gas outlet pipe 23, so that the liquid refrigerant in the accommodating chamber 12 can be discharged through the liquid supply port 112.

[0048] Not limited to this, in other embodiments, the liquid supply port 112 may also be arranged to be higher than the regenerator body 21 to ensure that the regenerator 20 is completely immersed in the liquid refrigerant in the accommodating chamber 12 .

[0049] In one embodiment, the regenerator 20 is disposed at the bottom of the cylinder 11, so that the regenerator 20 is located at the bottom of the accommodating cavity 12, further ensuring that the regenerator body 21, the air inlet pipe 22 and the air outlet pipe 23 are completely immersed in the liquid refrigerant, which is beneficial to improving the heat exchange effect.

[0050] like Figure 1As shown, in this embodiment, the heat regenerator 100 also includes a mounting seat 30, the heat regenerator body 21 is mounted on the mounting seat 30 by welding, and the mounting seat 30 is connected to the bottom of the cylinder 11, the mounting seat 30 is welded to the bottom of the accommodating cavity 12, and the heat regenerator body 21 is fixed to the bottom of the accommodating cavity 12 through the mounting seat 30, so that the heat regenerator body 21 can be installed stably.

[0051] Not limited to this, in other embodiments, the mounting seat 30 may also be fixed on the peripheral wall close to the bottom of the accommodating cavity 12, which is not limited here.

[0052] In one embodiment, the heat exchanger body 21 includes a plurality of heat exchange tubes, which are all arranged as straight tube structures and extend along the radial direction of the cylinder 11, and the plurality of heat exchange tubes are respectively connected and communicated with the air inlet pipe 22 and the air outlet pipe 23, wherein the temperature of the liquid refrigerant in the accommodating chamber 12 is greater than the temperature of the gaseous refrigerant in the heat exchange tube, and is used to perform heat exchange on the gaseous refrigerant flowing through the heat exchange tube.

[0053] Not limited to this, in other embodiments, all or part of the multiple heat exchange tubes may be configured as bent tube structures, which can be selected according to actual needs.

[0054] In one embodiment, the heat recovery liquid storage tank 100 also includes an air inlet external pipe 221 and an air outlet external pipe 231. The air inlet external pipe 221 is arranged outside the cylinder 11 and is connected and communicated with the air inlet pipe 22. The air outlet external pipe 231 is arranged outside the cylinder 11 and is connected and communicated with the air outlet pipe 23 to facilitate installation operation.

[0055] In this embodiment, the air inlet external pipe 221 is integrated with the air inlet pipe 22, and the air outlet external pipe 231 is integrated with the air outlet pipe 23. Of course, in other embodiments, the air inlet external pipe 221 and the air inlet pipe 22 can also be separated and fixed by welding, or the air outlet external pipe 231 and the air outlet pipe 23 can be integrated and fixed by welding.

[0056] In one embodiment, the cylinder 11 is further provided with a vent 13, which is arranged at the top of the cylinder 11 along the axial direction of the cylinder 11, and is arranged higher than the liquid drop port 111. In this way, a closed space is avoided in the cylinder 11, and the air pressure of the accommodating chamber 12 is balanced with that outside the cylinder 11, which is conducive to the liquid refrigerant to smoothly enter the accommodating chamber 12 from the liquid drop port 111.

[0057] In this embodiment, the vent 13 is opened at the top of the cylinder 11 so that the air in the accommodating cavity 12 can circulate with the air outside the cylinder 11 .

[0058] The present application also provides a refrigeration system, including a condenser, a compressor, an evaporator, a throttling element, a cold storage return air pipeline, and any of the above heat recovery liquid storage device 100, the condenser is connected to the accommodating chamber 12 through a liquid drop port 111, the liquid supply port 112 is connected to the evaporator through a throttling element, the evaporator is connected to the air inlet pipe 22 through the cold storage return air pipeline, and the air outlet pipe 23 is connected to the air intake port of the compressor. The refrigeration system using the above heat recovery liquid storage device 100 has lower construction difficulty, improves system installation efficiency and heat exchange effect, and ensures stable operation of the compressor to avoid liquid hammer risk.

[0059] In summary, when the refrigeration system is working, the compressor compresses the refrigerant to do work, and the high-temperature and high-pressure gaseous refrigerant is condensed by the condenser and becomes a liquid refrigerant, and the liquid refrigerant enters the receiving chamber 12 through the liquid drop port 111, and then is connected to the system liquid supply pipe through the liquid supply port 112. The system liquid supply pipe is connected to the throttling element, and the throttling element includes an expansion valve and a capillary tube. The refrigerant becomes a low-temperature and low-pressure gas-liquid two-phase refrigerant after throttling expansion. Then the refrigerant enters the evaporator again, and the refrigerant absorbs heat and evaporates into a saturated gaseous refrigerant in the evaporator. The saturated gaseous refrigerant enters the heat exchanger body 21 through the cold storage return air pipe and the air inlet pipe 22. The saturated gaseous refrigerant exchanges heat with the liquid refrigerant in the receiving chamber 12 in the heat exchange pipe. After the heat exchange, the saturated gaseous refrigerant becomes a gaseous refrigerant with a certain degree of superheat, which enters the suction pipe of the compressor through the air outlet pipe and returns to the compressor. In this way, the above cycle is repeated.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
