[0027] In order to better understand and implement, the technical scheme in the embodiment of the utility model will be clearly and completely described below in combination with the drawings in the embodiment of the utility model.

[0028] In the description of the utility model, it should be explained that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0030] Referring to Figure 1 The application provides an integrated refrigeration system, which comprises a compressor 1, a first heat exchange device 2, a throttling device 3 and a second heat exchange device 4 connected in sequence through a pipeline 5 to form a refrigerant circulation loop, so that the refrigerant can circulate in the refrigerant circulation loop to complete heat exchange.

[0031] The integrated refrigeration system comprises two working states: in the state that the refrigerant circulation loop is turned on, the first heat exchange device 2 exchanges heat with air; in the state that the refrigerant circulation loop is turned off and the second heat exchange device 4 is turned on, the second heat exchange device 4 exchanges heat with air. The second heat exchange device 4 comprises a refrigerant pipe 41 and a phase change pipe 42 connected in a sleeving manner, both ends of the refrigerant pipe 41 are connected with the pipeline 5 to enable the refrigerant to circulate in the circulation loop, and the phase change pipe 42 is filled with phase change material.

[0032] The working principle of the integrated refrigeration system is as follows:

[0033] In the case that the environment does not need to be refrigerated and the phase change material is in a liquid state, the compressor 1, the first heat exchange device 2, the throttling device 3 and the second heat exchange device 4 are turned on to turn on the refrigerant circulation loop, so that the refrigerant circulates in the refrigerant circulation loop. The compressor 1 compresses the refrigerant into a high-pressure high-temperature gaseous state, then the high-pressure high-temperature gaseous refrigerant flows into the first heat exchange device 2 through the pipeline 5 and exchanges heat with air in the first heat exchange device 2, so that the refrigerant is cooled, and the heat-exchanged air is blown out to the environment in the form of hot air. Then the cooled refrigerant flows in the pipeline 5 and is depressurized and cooled by the throttling device 3, and then flows into the second heat exchange device 4, where the refrigerant exchanges heat with the phase change material, the refrigerant absorbs heat to gradually cool the phase change material, and the heat-absorbed refrigerant flows back to the compressor 1 through the pipeline 5 for compression. This cycle is repeated until the phase change material completely changes into a solid state, i.e. the cold storage of the phase change material is completed.

[0034] When the environment needs to be refrigerated and cooled, the completely solid phase change material releases cold energy. At this time, the refrigerant circulation loop is turned off, i.e. the compressor 1, the first heat exchange device 2 and the throttling device 3 are turned off, and only the second heat exchange device 4 is turned on, and the phase change material exchanges heat with air in the second heat exchange device 4, the phase change material absorbs heat to gradually change into a liquid state, so that the heat-exchanged air is blown out to the environment in the form of cold air, and the refrigeration of the environment is realized.

[0035] The integrated refrigeration system is applied to the kitchen air conditioner, and since the kitchen air conditioner does not need to be turned on for a long time, only needs to be turned on for a short time when cooking in the kitchen, the time difference between cooking and not cooking in the kitchen can be utilized, when not cooking in the kitchen, the phase change material is stored in the cold state by utilizing the leisure time, then when cooking in the kitchen, the phase change material after being stored in the cold state is used to exchange heat with air to release cold energy to the air, air cooling is achieved, and the purpose of refrigeration of the environment is achieved.

[0036] The utility model discloses a refrigeration system is integrated in the air conditioner, and when refrigerating, the hot air is not discharged to the environment, high -efficient refrigeration is realized, the air conditioner has the characteristics of low power and low noise, and can be used directly, reduces the installation difficulty, realizes the miniaturization of air conditioner simultaneously, and reduces the production cost.

[0037] It is worth noting that first, although the kitchen cooking time is short, the integrated refrigeration system is not used for a long time, but the length of time of most kitchen cooking still needs to be considered to fill the phase change material with appropriate type and amount in the phase change pipe 42, so that the phase change material can release cold energy in the whole process of kitchen cooking. The phase change material can be hydrated salt, such as CaCl2·6H2O, Na2CrO4·10H2O, trifluoroethane hydrate, etc., and the phase change material can also be waxy material, such as paraffin wax, etc. In practical application, the type and amount of phase change material are selected according to design requirements, which is not limited here.

[0038] Second, although the phase change material releases cold energy to the environment during the storage process, since the kitchen is not used at this time, the hot air blown can be ignored under the condition that the environment temperature is not affected, and the temperature of the hot air can be gradually dissipated after the phase change material is stored in the cold state. However, it should be noted that the temperature of the integrated refrigeration system continuously blowing hot air into the environment should not be too high, and the time should not be too long, so as not to affect the service life of the compressor 1, and the high temperature affects the temperature of other rooms, and is not conducive to the heat dissipation of the environment, resulting in poor user experience. Therefore, when the phase change material is stored in the cold state, the storage can be stopped after a certain time and when the environment temperature is high, and then the storage is continued after the temperature is reduced to a certain extent, that is, the intermittent storage method is adopted until the phase change material is completely changed into solid state.

[0039] In the utility model, compressor 1 adopts the compressor for air conditioner heat exchange system on market, its purpose is to compress refrigerant into high pressure high temperature gaseous state, and provides power for refrigerant circulation loop. First heat exchange device 2 is the condenser on market, and it exchanges heat with air through refrigerant, so that refrigerant releases heat to reduce temperature, and transfers heat to air to blow hot air. Throttling device 3 is the expansion valve on market, and it is installed between condenser (first heat exchange device 2) and evaporator (second heat exchange device 4), and is transmitted to evaporator after throttling to reduce temperature and pressure, and the flow of refrigerant can be adjusted by controlling valve flow, to ensure that refrigerant is fully utilized when exchanging heat in evaporator. Second heat exchange device 4 is the improvement of evaporator on market, and refrigerant pipe 41 and phase change pipe 42 are connected by sleeving, and heat is exchanged with phase change material, refrigerant absorbs heat to increase temperature, and phase change material releases heat to gradually change from liquid state to solid state to store cold. And, the phase change material after storing cold can also exchange heat with air, and phase change material releases cold to air to blow cold air to realize refrigeration.

[0040] On this basis, first heat exchange device 2 exchanges heat with air through first fan 6, and second heat exchange device 4 exchanges heat with air through second fan 7, and first fan 6 and second fan 7 are opened alternately. That is, in the state that refrigerant circulation loop is conducted, first fan 6 is opened, so that refrigerant flows to first heat exchange device 2, and air is sucked or blown into first heat exchange device 2 by first fan 6, so that refrigerant exchanges heat with air passing through first heat exchange device 2, refrigerant is cooled and hot air is blown out, so as to absorb heat from phase change material after refrigerant flows to second heat exchange device 4, so that phase change material gradually changes to solid state to realize cold storage. In the state that refrigerant circulation loop is disconnected and second heat exchange device 4 is opened, air is sucked or blown into second heat exchange device 4 by second fan 7, so that phase change material exchanges heat with air passing through second heat exchange device 4, phase change material releases cold and blows cold air to achieve the purpose of refrigeration. Wherein, first fan 6 and / or second fan 7 are exhaust fan or blower.

[0041] The integrated refrigeration system further comprises a control device, the compressor 1, the first heat exchange device 2, the throttling device 3, the second heat exchange device 4, the first fan 6 and the second fan 7 are electrically connected with the control device, so as to realize the automatic control mode of the integrated refrigeration system. Therefore, in the case that the phase change material is liquid and the environment does not need to be refrigerated, the compressor 1, the first heat exchange device 2, the throttling device 3, the second heat exchange device 4 and the first fan 6 can be started by the control device, so that the refrigerant circulation loop is conducted, and the refrigerant circulates in the refrigerant circulation loop. The compressor 1 compresses the refrigerant into high-pressure high-temperature gas, and then the high-pressure high-temperature gas refrigerant flows into the first heat exchange device 2 through the pipeline 5, and exchanges heat with air in the first heat exchange device 2 through the first fan 6, so that the refrigerant is cooled, and the heat-exchanged air is blown out to the environment in the form of hot air. Then the cooled refrigerant flows in the pipeline 5 and flows to the second heat exchange device 4 after being decompressed and cooled by the throttling device 3, and the refrigerant exchanges heat with the phase change material in the second heat exchange device 4, so that the phase change material is gradually cooled by the heat absorption of the refrigerant, and the heat-absorbed refrigerant flows back to the compressor 1 for compression. Through the circulation, until the phase change material completely changes into solid state, that is, the cold storage of the phase change material is completed.

[0042] When the environment needs to be refrigerated and cooled, the completely solid phase change material after cold storage is used to release cold. At this time, the refrigerant circulation loop is disconnected by the control device, that is, the compressor 1, the first heat exchange device 2, the throttling device 3 and the first fan 6 are closed, and the second heat exchange device 4 and the second fan 7 are opened. The phase change material exchanges heat with air in the second heat exchange device 4 through the second fan 7, the phase change material gradually changes to liquid state by heat absorption, so that the heat-exchanged air is blown out to the environment in the form of cold air, and the refrigeration of the environment is realized.

[0043] Based on this, the integrated refrigeration system further comprises a flow sensor for detecting air flow and / or a temperature sensor for detecting environment temperature, the flow sensor and the temperature sensor are electrically connected with the control device, the flow sensor is arranged on the air flow channel of the first heat exchange device 2 and the second heat exchange device 4, and the temperature sensor is arranged on the compressor 1 and the position close to the environment. Therefore, the flow of the air for heat exchange at the first heat exchange device 2 and the second heat exchange device 4 can be monitored in real time by the flow sensor and transmitted to the control device, so as to facilitate the adjustment of the air flow by the control device according to the demand. The temperature sensor can be used to monitor the compressor 1 and the environment temperature in real time, so as to prevent the compressor 1 and / or the environment temperature from being too high during the cold storage process of the phase change material.

The two end portions of the refrigerant pipe 41 are connected with the pipeline 5, and the inner wall of the refrigerant pipe 41 is spaced from the outer wall of the phase change pipe 42 to form a flow channel for the refrigerant. Thus, in the working state of the phase change material storage, when the refrigerant flows to the second heat exchange device 4, the refrigerant can exchange heat with the phase change material through the wall of the phase change pipe 42, and the refrigerant absorbs heat to gradually change the phase change material from liquid to solid. In this embodiment, the two end portions of the phase change pipe 42 are directly and completely closed, and the sealing performance is good.

[0045] In the second embodiment, referring to Figure 3 The phase change pipe 42 is sleeved outside the refrigerant pipe 41, and the two end portions of the inner cavity of the refrigerant pipe 41 are connected with the pipeline 5 to form a flow channel for the refrigerant in the inner cavity of the refrigerant pipe 41. The two end portions of the phase change pipe 42 are respectively and sealingly connected with the outer walls of the corresponding refrigerant pipes 41 to form a closed cavity between the inner wall of the phase change pipe 42 and the outer wall of the refrigerant pipe 41, and the phase change material is filled in the closed cavity. Thus, in the working state of the phase change material storage, when the refrigerant flows to the second heat exchange device 4, the refrigerant can exchange heat with the phase change material through the wall of the refrigerant pipe 41, and the refrigerant absorbs heat to gradually change the phase change material from liquid to solid. In this embodiment, the phase change material is located outside the refrigerant, and in the refrigeration mode, the phase change material can directly exchange heat with the air through the wall of the phase change pipe 42, the heat exchange efficiency is high, and the high-efficiency refrigeration is facilitated.

[0046] Whether it is the first embodiment or the second embodiment, the shape of the refrigerant pipe 41 is matched with the shape of the phase change pipe 42 to ensure that the refrigerant pipe 41 and the phase change pipe 42 are effectively sleeved. The length of the refrigerant pipe 41 is not less than the length of the phase change pipe 42, so that the two end portions of the refrigerant pipe 41 can be connected with the pipeline 5 to form a complete refrigerant circulation loop.

[0047] Preferably, the length of the refrigerant pipe 41 is equal to the length of the phase change pipe 42. During the flow of the refrigerant in the refrigerant pipe 41, the refrigerant and the phase change material always exchange heat to accelerate the phase change of the phase change material from liquid to solid, and the efficiency of the phase change material storage is improved.
