DETAILED DESCRIPTION

[0035] The present application will be described in detail below with reference to the embodiments shown in the drawings. However, the embodiments do not limit the present application, and the structural, method, or functional changes made by those skilled in the art based on the embodiments are included in the protection scope of the present application.

[0036] Reference Figures 1 to 6As shown, the refrigeration equipment 100 provided by the present application comprises a cabinet 10 made of a predetermined thermal insulation plate, and the cabinet 10 is internally provided with a first chamber 101, a second chamber 102 and a cold storage chamber 103. The second chamber 102 is set to have a higher temperature than the first chamber 101.

[0037] The refrigeration equipment 100 further comprises a refrigeration system for providing cold to the first chamber 101, and the refrigeration system comprises a refrigeration unit 21 and an air cooling device 22 arranged in the first chamber 101. The air cooling device 22 mainly comprises an evaporator connected to the refrigeration unit 21 and a first fan arranged in cooperation with the evaporator. The air in the first chamber 101 flows through the evaporator under the action of the first fan, so as to achieve cooling.

[0038] The cold storage chamber 103 is provided with a cold storage device 3, and the cold storage device 3 is filled with a corresponding phase change cold storage material to achieve cold storage. The phase change temperature of the phase change cold storage material is higher than the set temperature of the first chamber 101. The refrigeration equipment 100 further comprises a first cold transfer system for transferring the cold of the first chamber 101 to the cold storage chamber 103, and the first cold transfer system comprises a cold storage fan 4 arranged in the cold storage chamber 103. Understandably, the cold storage fan 4 can also be arranged in the first chamber 101, as long as the air in the first chamber 101 can be smoothly blown into the cold storage chamber 103.

[0039] The refrigeration equipment 100 further comprises a second cold transfer system, and the second cold transfer system comprises a cooler 51 arranged in the second chamber 102, a cooling pipe 52 connected to the cooler 51 and the cold storage device 3, and a circulating pump 53 arranged on the cooling pipe 52. The cooling pipe 52 is filled with a predetermined cooling agent, and the cooling agent flows along the cooling pipe 52 after heat exchange with the cold storage device 3, so as to transfer the cold stored in the cold storage device 3 to the second chamber 102, and then achieve cooling of the second chamber 102 through the cooler 51. The cooler 51 is arranged in heat exchange with part of the cooling pipe 52, or is composed of part of the cooling pipe 52.

[0040] The refrigeration system of the refrigeration equipment 100 only needs to supply cold to the first chamber 101, and the structure design is more simple, which reduces the structure design and assembly difficulty of the refrigeration system. The cold storage device 3 can store cold in off-peak hours when the demand for cold in the first chamber 101 is low, and conversely, when the demand for cold of the refrigeration equipment 100 is high, the cold storage device 3 can release the cold stored therein. The refrigeration equipment 100 can reduce the power demand of the refrigeration system, and it is also more convenient to use electricity.

[0041] In this embodiment, the refrigeration equipment 100 is specifically set as a mobile convenience store, and the box body 10 is integrally set in a cuboid shape. The first chamber 101 is a freezing chamber; and the second chambers 102 are set as two, one of which is set as a refrigerating chamber, and the other is set as an operating chamber.

[0042] Here, the cooler 51 is arranged in the refrigerating chamber, and is used to supply cold to the refrigerating chamber. A fan (not shown) is further arranged between the refrigerating chamber and the operating chamber, and can be used to transfer part of the cold in the refrigerating chamber to the operating chamber according to actual needs. That is, the cooler 51 arranged in the refrigerating chamber can supply cold to the two second chambers 102 at the same time. With the above design, the manufacturing cost and assembly difficulty of the second cold transfer system are further reduced, and the control is also more convenient.

[0043] The first chamber 101 is located above the cold storage chamber 103, and a temperature insulation plate 61 is arranged between the cold storage chamber 103 and the first chamber 101, which is used to limit the cold of the first chamber 101 from being transmitted to the cold storage chamber 103 without limitation. Of course, in order to ensure the communication and cold transfer between the first chamber 101 and the cold storage chamber 103, the temperature insulation plate 61 does not completely separate the two. Generally, the highest temperature of the cold storage chamber 103 corresponds to the phase change temperature of the phase change cold storage material used by the cold storage device 3, so that the temperature insulation plate 61 can be selected according to the difference between the phase change temperature of the phase change cold storage material and the set temperature of the first chamber 101, so as to meet the heat insulation requirement of the cold storage chamber 103 and the first chamber 101. Here, the temperature insulation plate 61 is preferably arranged in a spaced manner with the cold storage device 3, so as to reduce the direct transmission of cold.

[0044] It should be noted that the first chamber 101 and the cold storage chamber 103 can also be obtained by dividing a predetermined refrigeration chamber by the temperature insulation plate 61, and the temperature insulation plate 61 is not limited to a flat plate structure, and can be any structure as long as it can separate the cold storage device 3 and the first chamber 101. In actual manufacturing process, the cold storage device 3 is usually first placed in a predetermined refrigeration chamber, and then the temperature insulation plate 61 is installed in the refrigeration chamber, so as to form the first chamber 101 and the cold storage chamber 103.

[0045] The refrigeration equipment 100 further comprises a mechanical room 104 for accommodating the refrigeration unit 21, the mechanical room 104 is arranged adjacent to the cold storage room 103 and also located below the first chamber 101. A first partition 62 is arranged between the mechanical room 104 and the first chamber 101; a second partition 63 is arranged between the mechanical room 104 and the cold storage room 103. Specifically, the cold storage room 103 and the mechanical room 104 are arranged adjacent to each other in front and back and have a comparable height; the first chamber 101 has oppositely arranged first side wall 11 and second side wall 12, here, the first side wall 11 and the second side wall 12 are respectively the front wall and the rear wall of the cabinet 10.

[0046] In order to achieve heat dissipation of the refrigeration unit 21, the mechanical room 104 can be arranged in an open manner. A corresponding cover plate 13 can also be arranged at the mechanical room 104 to avoid damage to the refrigeration unit 21. The cover plate 13 is preferably arranged in a hollow manner to facilitate heat dissipation of the refrigeration unit 21. Of course, the cover plate 13 can also be pivotally installed on the side of the mechanical room 104 to facilitate opening or closing of the mechanical room 104.

[0047] The refrigeration equipment 100 further comprises a first air duct cover plate 71 and a second air duct cover plate 72 arranged adjacent to the first side wall 11 and the second side wall 12 respectively, the first air duct cover plate 71 and the first side wall 11 form an air inlet duct 701, and the second air duct cover plate 72 and the second side wall 12 form an air return duct 702. The air cooling device 22 is correspondingly arranged at the outlet position of the air return duct 702. Specifically, the air cooling device 22 is arranged close to the second side wall 12 and located at the top of the first chamber 101, and the air outlet direction of the air cooling device 22 is preferably arranged forward.

[0048] The second air duct cover plate 72 extends upward beyond the first air duct cover plate 71, that is, the outlet of the air return duct 702 is closer to the air cooling device 22, reducing the influence of the gas flowing back from the cold storage room 103 on the local temperature of the first chamber 101. The upper edge of the second air duct cover plate 72 is also folded inward toward the inside of the first chamber 101 to form a wind guide portion 721, which reduces the flow rate of the gas flowing out of the air return duct 702 and reduces turbulence. The upper edge of the first air duct cover plate 71 can also be arranged to be folded inward toward the inside of the first chamber 101 to increase the flow of cold air into the cold storage room 103. The first air duct cover plate 71 and the second air duct cover plate 72 can be designed according to actual storage and cold storage requirements.

[0049] The cold storage fan 4 of the first cold quantity transmission system is arranged below the air inlet duct 701 and corresponds to the cold storage device 3 in the front-rear direction. In actual operation, the air flow entering the air inlet duct 701 is controlled by the operation of the cold storage fan 4. In particular, when the cold storage fan 4 stops operating, only a small amount of cold air enters the cold storage chamber 103, and the cold storage device 3 can be regarded as stopping cold storage.

[0050] The refrigeration equipment 100 further comprises a bearing plate 73 arranged above the temperature insulation plate 61 and the first partition plate 62, which is used to stack the objects to be frozen and stored, and the bearing plate 73 is connected with the first air duct cover plate 71 and the second air duct cover plate 72. The bearing plate 73 is arranged in a spaced manner with the temperature insulation plate 61; a plurality of support ribs 74 are arranged between the temperature insulation plate 61 and the bearing plate 73, and the support ribs 74 are arranged in an extending manner in the front-rear direction. The temperature insulation plate 61 is aligned with the first partition plate 62 in the height direction, the support ribs 74 extend backward beyond the temperature insulation plate 61, and the support ribs 74 are fixed on the temperature insulation plate 61 and the first partition plate 62. Preferably, the support ribs 74 extend backward to the second side wall 12 to stably support the bearing plate 73.

[0051] The rear edge of the temperature insulation plate 61 is also arranged in a spaced manner with the second partition plate 63 in the front-rear direction; an air flow channel is formed between the bearing plate 73 and the first partition plate 62, so that the gas leaving the cold storage chamber 103 can enter the return air duct 702 through the air flow channel and then return to the first compartment 101. In order to avoid the gas entering the first compartment 101 from directly flowing through the space between the temperature insulation plate 61 and the bearing plate 73, a baffle 75 is arranged between the temperature insulation plate 61 and the bearing plate 73, which extends in a direction perpendicular to the support ribs 74 and is located at the front end of the support ribs 74.

[0052] The front end of the temperature insulation plate 61 is also provided with a mounting plate 76, which is fixed on the first side wall 11 and is provided with a ventilation opening 761 penetrating in the up-down direction, so that the gas in the air inlet duct 701 can flow into the cold storage chamber 103 under the action of the cold storage fan 4. In addition, a rib plate 77 arranged in a vertical direction is arranged between the second air duct cover plate 72 and the second side wall 12, which is used to fix the second air duct cover plate 72 and keep the structure of the return air duct 702 stable.

[0053] Referring to Figure 7 With Figure 8As shown, the cold storage device 3 comprises a plurality of adjacent cold storage tubes 31, pipes 32 connecting two of the cold storage tubes 31, and a support plate 33 for mounting the cold storage tubes 31, wherein the cold storage tubes 31 are filled with phase change cold storage material. Specifically, the cold storage tube 31 comprises an inner tube 311 and an outer tube 312, and the phase change cold storage material is arranged between the inner tube 311 and the outer tube 312. The cold storage tube 31 further comprises fins 313 connected to the inner tube 311 and / or the outer tube 312 and arranged between the inner tube 311 and the outer tube 312. Here, a plurality of the cold storage tubes 31 are arranged in parallel in the front-to-back direction, and heat exchange air channels are formed between adjacent cold storage tubes 31. The air blown into the cold storage chamber 103 from the first chamber 101 flows along the heat exchange air channels from one end of the cold storage tube 31 to the other end. The support plate 33 is provided with through holes 331 corresponding to the heat exchange air channels, so that the cold air can smoothly flow through the heat exchange air channels from front to back, thereby achieving cold storage of the cold storage device 3.

[0054] The second cold quantity transmission system comprises a liquid inlet pipe and a liquid outlet pipe connected to the inner tube 311 of the corresponding cold storage tube 31, so that the second cold quantity transmission system can exchange heat with the phase change cold storage material when the cold carrier flows through the inner tube 311. Through the circulation pump 53 and in cooperation with the corresponding control valve, the cold quantity accumulated in the cold storage device 3 can be controllably transmitted to the corresponding second chamber 102.

[0055] In another embodiment of the present application, the second chamber 102 is provided as at least two, and each of the second chambers 102 is provided with a corresponding cooler 51. Figure 9 As shown, the second chamber 102 comprises a refrigeration chamber and an operation chamber, and the cold storage device 3 comprises a first cold storage assembly 301 and a second cold storage assembly 302. The first cold storage assembly 301 is connected to the cooler 51 in the refrigeration chamber, and the second cold storage assembly 302 is connected to the cooler 51 in the operation chamber. Here, because the cold quantity requirements of the two second chambers 102 are inconsistent, the first cold storage assembly 301 and the second cold storage assembly 302 have different numbers of cold storage tubes 31. As an example, the cold storage device 3 comprises four groups of cold storage tubes 31, the first cold storage assembly 301 has three groups of cold storage tubes 31 connected to each other, and the second cold storage assembly 302 is composed of one group of cold storage tubes 31.

[0056] In summary, the refrigeration equipment 100 supplies cold to the first chamber 101 through the refrigeration system, and then controllably transfers the cold in the first chamber 101 to the cold storage chamber 103 through the cold storage fan 4, and transfers the cold stored in the cold storage device 3 to the second chamber 102 through the second cold transfer system. The refrigeration equipment has a more simple structure, can carry out cold storage in off-peak hours, can reduce the power requirement of the refrigeration system and the equipment cost, and is beneficial to market promotion and application.
