[0024] This utility model provides a refrigeration system, the advantages of which are:

[0025] Under normal water supply conditions, the switching valve is switched to the second cold tank. The cooling medium enters the second evaporator through the second capillary tube to cool the drinking water in the second cold tank, and then enters the cooling assembly through the main cooling medium pipe to form a cooling medium circulation loop. At this time, drinking water flows into the second cold tank from the second inlet pipe, is cooled by the second evaporator to form low-temperature chilled water, and then flows out from the main outlet pipe for users to use. During peak cold water usage periods, if the cold water supply in the second cold tank is insufficient, the switching valve is switched to the first cold tank. The cooling medium enters the first evaporator through the first capillary tube, and then enters the cooling assembly through the main cooling medium pipe to form a cooling medium circulation loop. At this time, drinking water flows from the first inlet pipe through the first and second cold tanks to the main outlet pipe. Because the first cold tank contains a refrigerant, which releases cold energy at higher temperatures, the drinking water in the first inlet pipe can be continuously cooled, and the chilled water in the first inlet pipe can continuously flow out from the main outlet pipe for users to use. On the other hand, the cold water in the first inlet pipe will also cool the drinking water in the second cold tank when it passes through the second cold tank. In this way, the cold water in the first inlet pipe and the cold water in the second cold tank will both flow out from the main outlet pipe, which can meet the demand for a large amount of cold water and can quickly replenish the cold water storage in a short time for users to use.

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0033] like Figure 1As shown, this utility model embodiment provides a refrigeration system, which includes a first refrigeration module, a second refrigeration module, a cooling module, and a water supply module. The first refrigeration module includes a first cold tank 11 and a first evaporator 12, with the first evaporator 12 disposed inside the first cold tank 11, which contains a refrigerant. The second refrigeration module includes a second cold tank 21 and a second evaporator 22, with the second evaporator 22 disposed inside the second cold tank 21. The cooling module includes a cooling assembly 31, a cooling medium main pipe 32, and a switching valve 33, with the cooling assembly 31 and the switching valve 33 disposed on the cooling medium main pipe 32. The cooling assembly 31 is used to drive the cooling medium. The cooling medium flows through the main cooling medium pipe 32 to the switching valve 33. The switching valve 33 is connected to the inlet of the first evaporator 12 through the first capillary tube 41. The switching valve 33 is also connected to the inlet of the second evaporator 22 through the second capillary tube 42. The outlets of the first evaporator 12 and the second evaporator 22 are connected to the cooling assembly 31 through the main cooling medium pipe 32. The water supply module includes a first water inlet pipe 51, a second water inlet pipe 52, and a main water outlet pipe 53. The second water inlet pipe 52 and the main water outlet pipe 53 are respectively connected to the second cold tank 21. The first water inlet pipe 51 passes through the first cold tank 11 and the second cold tank 21 and is connected to the main water outlet pipe 53.

[0034] In this embodiment, the cold storage agent, also known as a refrigerant, can absorb and store a large amount of cold energy at low temperatures and release a large amount of cold energy at higher temperatures, thereby maintaining a low-temperature environment within itself and a small surrounding area for a relatively long time. The working principle of the cold storage agent is as follows: When the cooling component 31 is working, the cooling medium (such as refrigerant) evaporates and absorbs heat, causing the cold storage agent to freeze and store cold energy; when the cooling component 31 stops working, the cold storage agent melts and absorbs heat to maintain the low temperature of the cooled object or the cooled space.

[0035] The first cold tank 11 is used to store refrigerant, and the second cold tank 21 is used to store drinking water that needs to be heated or cooled. The first cold tank 11 and the second cold tank 21 can be cylindrical or cuboid, or elliptical, conical, or irregular in shape, etc., and this embodiment does not impose specific limitations.

[0036] The cooling assembly 31 is installed outside the first cold tank 11 and the second cold tank 21 to drive the cooling medium to circulate within the cooling medium main pipe 32, the first evaporator 12 and the second evaporator 22, absorbing and removing heat from the first cold tank 11 and the second cold tank 21.

[0037] In one embodiment, the cooling assembly 31 includes a compressor 311, a condenser 312, and a dryer filter 313. The first end of the compressor 311 is connected to the third port of the first tee pipe 14, the second end of the compressor 311 is connected to the first end of the condenser 312, the second end of the condenser 312 is connected to the first end of the dryer filter 313, and the second end of the dryer filter 313 is connected to the switching valve 33.

[0038] Specifically, compressor 311 is used to compress a low-temperature, low-pressure gaseous cooling medium into a high-temperature, high-pressure gaseous cooling medium. The first end of compressor 311 is connected to the outlets of the first evaporator 12 and the second evaporator 22 via a cooling medium main pipe 32, receiving the low-temperature, low-pressure gaseous cooling medium flowing from the first evaporator 12 and the second evaporator 22. The second end of compressor 311 is connected to the first end of condenser 312, delivering the high-temperature, high-pressure gaseous cooling medium into condenser 312.

[0039] The condenser 312 is located between the compressor 311 and the dryer filter 313. The condenser 312 is used to condense the high-temperature, high-pressure gaseous cooling medium into a high-temperature, high-pressure liquid cooling medium, thereby releasing heat to the external environment. Cooling medium flows inside the condenser 312, and externally, a fan or cooling water is typically used to dissipate heat from the cooling medium.

[0040] The dryer filter 313 is used to remove moisture and other impurities from the cooling medium. In this embodiment, the first end of the dryer filter 313 is connected to the second end of the condenser 312, receiving the high-temperature, high-pressure liquid cooling medium. The second end of the dryer filter 313 is connected to the switching valve 33 via a pipe, through which the liquefied cooling medium is sent to the first refrigeration module or the second refrigeration module.

[0041] The working process of the cooling assembly 31 is as follows: First, the compressor 311 is started, compressing the low-temperature, low-pressure gaseous cooling medium flowing from the evaporators in the two cold tanks into a high-temperature, high-pressure gaseous cooling medium. Then, the high-temperature, high-pressure gaseous cooling medium enters the condenser 312 for condensation and heat release, becoming a high-temperature, high-pressure liquid cooling medium. Next, the liquid cooling medium passes through the dryer filter 313 for drying and filtration to remove moisture and other substances.

[0042] Furthermore, the switching valve 33 has two outlet pipes. The first outlet pipe is connected to the inlet of the first evaporator 12 via the first capillary tube 41, and the second outlet pipe is connected to the inlet of the second evaporator 22 via the second capillary tube 42. The outlets of both the first evaporator 12 and the second evaporator 22 are connected to the cooling assembly 31 via the cooling medium main pipe 32, forming a closed-loop circulation circuit for the cooling medium. The first capillary tube 41 and the second capillary tube 42 are a throttling structure used to reduce the pressure of the high-temperature, high-pressure liquid cooling medium into a low-temperature, low-pressure liquid cooling medium.

[0043] Based on the above technical solution, under normal water supply conditions, the switching valve 33 is switched to the second cold tank 21. The cooling medium enters the second evaporator 22 through the second capillary tube 42 to cool the drinking water in the second cold tank 21, and then enters the cooling assembly 31 from the cooling medium main pipe 32 to form a cooling medium circulation loop. At this time, drinking water flows into the second cold tank 21 from the second inlet pipe 52, is cooled by the second evaporator 22 to form low-temperature cold water, and flows out from the outlet main pipe 53 for users to use. During peak cold water usage periods, if the cold water supply in the second cold tank 21 is insufficient, the switching valve 33 is switched to the first cold tank 11. The cooling medium enters the first evaporator 12 from the first capillary tube 41, and then enters the cooling assembly 31 from the cooling medium main pipe 32 to form a circulation loop. At this time, drinking water flows from the first inlet pipe 51 through the first cold tank 11 (but does not enter the first cold tank 11) and the second cold tank 21 to the main outlet pipe 53. Since the first cold tank 11 contains a refrigerant, based on the characteristics of the refrigerant (a substance that absorbs and stores a large amount of cold energy at low temperatures and releases cold energy at higher temperatures), the drinking water in the first inlet pipe 51 can be continuously cooled, and the cold water in the first inlet pipe 51 can continuously flow out from the main outlet pipe 53 for users to use. On the other hand, the cold water in the first inlet pipe 51 also cools the drinking water in the second cold tank 21 when it passes through the second cold tank 21. In this way, the cold water in the first inlet pipe 51 and the cold water in the second cold tank 21 both flow out from the main outlet pipe 53, which can meet the demand for a large amount of cold water and can quickly replenish the cold water storage in a short time for users to use.

[0044] In this embodiment, the switching valve 33 can be a three-way electric valve or a three-way solenoid valve. The switching valve 33 can be used to switch to the first capillary tube 41 or the second capillary tube 42 respectively to meet the normal cooling water supply demand and the peak period large cooling water supply demand.

[0045] In some embodiments, in order to reduce heat loss, the first cold tank 11 and the second cold tank 21 may be insulated with insulation materials or structures, such as one or more layers of insulation material (not shown in the figures) on the outer wall of the first cold tank 11 and the second cold tank 21.

[0046] In one embodiment, the water supply module further includes a main inlet pipe 54 and an inlet tee pipe 55. The main inlet pipe 54 is connected to the first interface of the inlet tee pipe 55. The first end of the first inlet pipe 51 is connected to the second interface of the inlet tee pipe 55. The first end of the second inlet pipe 52 is connected to the third interface of the inlet tee pipe 55. The second end of the second inlet pipe 52 is connected to the second cold tank 21. The first end of the outlet main pipe 53 is connected to the second cold tank 21. The second end of the first inlet pipe 51 is connected to the second end of the outlet main pipe 53.

[0047] Specifically, the inlet tee pipe 55 is a tee pipe structure with three interfaces: a first interface, a second interface, and a third interface, allowing the three pipes to be connected at the three interfaces respectively. In this embodiment, the main inlet pipe 54 is the water source inlet of the entire water supply system. The main inlet pipe 54 is used to distribute external drinking water to the first inlet pipe 51 and the second inlet pipe 52 through the inlet tee pipe 55. Under normal water supply conditions, drinking water enters the second cold tank 21 from the second inlet pipe 52 and is cooled by the second evaporator 22. During peak cold water usage periods, drinking water continuously passes through the first cold tank 11 from the first inlet pipe 51 and is cooled by the refrigerant. After being cooled by the second evaporator 22 or the refrigerant in the first cold tank 11, it is collected from the outlet main pipe 53 and flows out to the outside, thereby meeting the normal cold water supply demand and the peak demand for large-volume cold water supply respectively.

[0048] In one embodiment, the first water inlet pipe 51 includes a water inlet pipe section 511, a heat exchange pipe section 512, and a water storage pipe section 513; the first end of the water inlet pipe section 511 is connected to the second interface of the water inlet tee pipe 55; the heat exchange pipe section 512 is disposed in the first cold tank 11, and the first end of the heat exchange pipe section 512 passes through the first cold tank 11 and is connected to the second end of the water inlet pipe section 511; the water storage pipe section 513 is disposed in the second cold tank 21, and the first end of the water storage pipe section 513 passes through the second cold tank 21 and is connected to the second end of the heat exchange pipe section 512, and the second end of the water storage pipe section 513 is connected to the second end of the main water outlet pipe 53.

[0049] Specifically, in this embodiment, the first water inlet pipe 51 is divided into a water inlet pipe section 511, a heat exchange pipe section 512, and a water storage pipe section 513 connected in sequence. The water inlet pipe section 511 is the water inlet pipe located outside the first cold tank 11, the heat exchange pipe section 512 is the heat exchange pipe located inside the first cold tank 11, and the water storage pipe section 513 is the water storage pipe located inside the second cold tank 21. The heat exchange pipe section 512 exchanges heat with the refrigerant in the first cold tank 11 to continuously cool the drinking water in the first water inlet pipe 51. The water storage pipe section 513 can store a certain amount of cold water in the second cold tank 21 and also cool the drinking water in the second cold tank 21. The drinking water from the heat exchange pipe section 512 to the water storage pipe section 513 can either flow by gravity to the water storage pipe section 513 or be pumped there under pressure; this embodiment does not impose specific limitations.

[0050] In one embodiment, an inlet valve 56 is provided on the inlet pipe section 511, and an outlet valve 57 is provided on the outlet main pipe 53.

[0051] Specifically, in this embodiment, the inlet valve 56 is installed on the inlet pipe section 511 (or the first inlet pipe 51) to control the flow rate of drinking water in the first inlet pipe 51. Similarly, the outlet valve 57 is installed on the outlet main pipe 53 to control the flow rate of cooled drinking water to meet the user's needs.

[0052] For example, the inlet valve 56 and outlet valve 57 can be solenoid valves to achieve remote control and automatic adjustment. For instance, when the amount of drinking water needs to be increased, the control system sends a signal to the solenoid valves to open the inlet valve 56 and outlet valve 57, allowing more drinking water to enter the first cold tank 11, be cooled, and then flow out. Conversely, when the amount of drinking water needs to be reduced, the opening of the inlet valve 56 and outlet valve 57 is closed or reduced. Of course, the inlet valve 56 and outlet valve 57 can also be manual valves for easy manual adjustment.

[0053] In some embodiments, a filter screen may be provided at the inlet end of the main water inlet pipe 54 to prevent impurities and particulate matter from entering the cooling system.

[0054] In one embodiment, in the vertical direction, the height of the first cold tank 11 is greater than the height of the second cold tank 21; the heat exchange pipe section 512 extends and bends within the first cold tank 11 in the vertical direction; and / or the water storage pipe section 513 extends and bends within the second cold tank 21 in the vertical direction.

[0055] Specifically, the heat exchange tube section 512 bends and extends within the first cold tank 11, increasing the flow length of drinking water within it and thus increasing the contact time between the drinking water and the refrigerant, further improving the heat exchange efficiency between the drinking water and the refrigerant. In practical applications, the bend and extension shape of the heat exchange tube section 512 can be designed according to parameters such as the internal space of the first cold tank 11, the flow rate and pressure of the cooling medium. The water storage tube section 513 bends and extends within the second cold tank 21, providing a larger storage space and allowing for the storage of more cold water in a short time to meet peak water demand.

[0056] In this embodiment, the horizontal height of the first cold tank 11 is greater than that of the second cold tank 21, and drinking water can flow from the heat exchange pipe section 512 to the water storage pipe section 513 under the action of gravity, and then flow from the water storage pipe section 513 to the main water outlet pipe 53.

[0057] In some embodiments, the heat exchange tube section 512 is spirally arranged from top to bottom and compactly filled in the first cold tank 11. The spiral structure allows the heat exchange tube section 512 to provide a larger heat exchange area in a limited space, further improving the heat exchange efficiency between drinking water and the cold storage agent.

[0058] In one embodiment, the water supply module further includes a water outlet tee pipe 58 and a main water outlet valve 59. The second end of the water storage pipe section 513 is connected to the first interface of the water outlet tee pipe 58, the second end of the main water outlet pipe 53 is connected to the second interface of the water outlet tee pipe 58, and the third interface of the water outlet tee pipe 58 is connected to the main water outlet valve 59.

[0059] Specifically, the structure of the outlet tee pipe 58 is similar to that of the inlet tee pipe 55, and it also has three interfaces, which will not be described in detail here. When drinking water is cooled by the second evaporator 22, it flows from the outlet tee pipe 58 to the outlet tee pipe 58; when drinking water is cooled by the refrigerant in the first cold tank 11, it flows from the water storage pipe section 513 to the outlet tee pipe 58, and then flows through the outlet tee pipe 58 to the main outlet valve 59, thereby meeting the normal cooling water supply demand and the peak period large-volume cooling water supply demand respectively.

[0060] In one embodiment, the first refrigeration module includes a first return pipe 13 and a first tee pipe 14. The first end of the first return pipe 13 is connected to the outlet of the first evaporator 12, and the second end of the first return pipe 13 is connected to the first port of the first tee pipe 14. The second refrigeration module includes a second return pipe 23. The first end of the second return pipe 23 is connected to the outlet of the second evaporator 22, and the second end of the second return pipe 23 is connected to the second port of the first tee pipe 14. The third port of the first tee pipe 14 is connected to the cooling medium main pipe 32.

[0061] Specifically, the structure of the first tee pipe 14 is similar to that of the water inlet tee pipe 55, with three ports, which will not be described in detail here. The first return pipe 13 is used to introduce the low-temperature, low-pressure gaseous cooling medium flowing out of the first evaporator 12 into the first tee pipe 14, and the second return pipe 23 is used to introduce the low-temperature, low-pressure gaseous cooling medium flowing out of the second evaporator 22 into the first tee pipe 14, and then connects to the cooling assembly 31 through the first tee pipe 14 and the cooling medium main pipe 32 to form a cooling medium circulation loop.

[0062] In one embodiment, the first cold tank 11 is provided with a first temperature monitoring device 15 and a first water level monitoring device 16, and the second cold tank 21 is provided with a second temperature monitoring device 24 and a second water level monitoring device 25.

[0063] Specifically, the first water level monitoring device 16 is used to monitor the water level in the first cold tank 11 in real time, and the second water level monitoring device 25 is used to monitor the water level in the second cold tank 21 in real time to avoid water shortage or overflow, so that the refrigeration system can automatically adjust according to the water level change to avoid the water level being too high and causing full water, or the water level being too low and causing insufficient water supply.

[0064] In some embodiments, the water level monitoring device employs a water level gauge. The type of water level gauge can be selected based on the shape, size, and monitoring requirements of the cold tank. Common types of water level gauges include float-type water level gauges and pressure-type water level gauges. Float-type water level gauges utilize the buoyancy of a float to move up and down with changes in water level, converting the float's position into a water level signal mechanically or electronically. Pressure-type water level gauges calculate the water level by measuring the water pressure exerted on the bottom or sidewalls of the cold tank.

[0065] In some embodiments, the first temperature monitoring device 15 is used to monitor the temperature inside the first cold tank 11 in real time, and the second temperature monitoring device 24 is used to monitor the temperature inside the second cold tank 21 in real time, so as to keep the drinking water within a suitable low temperature range.

[0066] In some embodiments, the bottom of the second cold tank 21 is connected to a first drain pipe 61, and the outlet of the water storage pipe section 513 can also be connected to a second drain pipe 62. The first drain pipe 61 and the second drain pipe 62 converge at a drain valve 65 via a drain tee pipe 63, through which the drinking water in the refrigeration system can be drained. Further, the second drain pipe 62 is provided with a second tee pipe 64. The first port of the second tee pipe 64 is connected to the water storage pipe section 513, the second port of the second tee pipe 64 is connected to the second drain pipe 62, and the second port of the second tee pipe 64 is connected to the outlet tee pipe 58. That is, the drinking water in the water storage pipe section 513 flows from the second tee pipe 64 to the outlet tee pipe 58, or it can flow from the second tee pipe 64 to the drain tee pipe 63.

[0067] Secondly, this utility model embodiment also provides a water dispenser, including a refrigeration system.

[0068] Specifically, in addition to the refrigeration system, the water dispenser in this embodiment is also equipped with a heating system, a water treatment system, and a control system.

[0069] The heating system includes a heating element that activates when the user needs hot water, heating the water in the tank to a preset temperature to provide warm drinking water. The water treatment system includes multi-stage filtration devices, such as activated carbon filters, ultrafiltration membranes, or reverse osmosis membranes. These filtration devices remove impurities, odors, residual chlorine, and harmful substances such as heavy metals from the water, providing safe drinking water. The control system typically includes a microprocessor, sensors, a display screen, and buttons. The user can select the desired drinking water temperature via buttons or a touchscreen.
