Description

An instant cooling system for drinking water and a district cooling system

Technical field

The invention relates to the field of drinking water and beverages, in particular to an instant cooling system used in a water dispenser and a beverage dispenser, and a partitioned refrigeration system.

Background technique

The instant water heating system is widely used in many scenes such as drinking fountains, coffee machines, kitchens, bathrooms, etc. The advantage of instant heating is that it is ready to use, does not require heat preservation, storage and repeated boiling, and its heating technology is simple. Heating to the boiling point in a few seconds is mainly related to the power of the heating device. For example, a 3000 watt heating element can produce 0.9 liters of boiling water at 98 degrees per minute, and a 6000 watt heating element can produce about 2 liters of boiling water at 98 degrees per minute.

However, the water is cold. No relevant solutions have been seen in the currently known technologies and practical products. In order to meet the existing cold water or water dispensers, beverage dispensers to prepare beverages of different temperatures or other needs, the corresponding equipment A refrigeration system needs to be configured. The current common cooling method is to use copper coils in the sink to exchange heat to the water in the sink to cool the water stored in the sink. However, due to the low thermal conductivity of the water, it is placed in the sink The copper coil inside will freeze, which will greatly reduce the cooling efficiency in the long term. And, especially for water dispensers, part of the prepared cold water will be used to prepare drinking beverages. The existing scheme of cooling the water through copper coils may bring bacteria and germs into the drinking water, thereby Affect the quality and flavor of the prepared beverage.

The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Its cooling efficiency is much higher than that of copper tube heat exchange. The plate heat exchanger is used for heat exchange. It can even directly change room temperature water into cold water to achieve instant cooling effect. However, the use of plate heat exchangers for heat exchange also has major drawbacks: when the compressor and water pump at both ends of the plate heat exchanger stop working unexpectedly, a high-pressure refrigerant is stored between the compressor and the capillary tube, which is compressed After the machine is unexpectedly powered off, it takes a long time to release the pressure of the refrigerant, and the refrigerant will continuously reduce the temperature of the refrigerant passage of the plate heat exchanger during the pressure release process, and the water circulation pipeline of the plate heat exchanger Also stop the water circulation heat exchange, it will cause the water in the water circulation channel of the plate transducer to freeze instantaneously, and the water freezes to cause volume expansion, which will lead to the damage of the plate transducer, and the refrigeration system involves extremely welding construction. Complicated, damage to the plate heat exchanger will also cause inconvenient maintenance and high maintenance costs.

In addition, due to actual requirements in different places during the application process, or even in unmanned operating places, accidental power failure, accidental tripping, misoperation, and movement will all cause the above-mentioned defects.

In addition, the current refrigeration system also has the following problems: the refrigeration system cannot achieve the effect of zone refrigeration well, so that the refrigeration effect of different areas is different, which further leads to the damage of the stored materials; Partition refrigeration, once a component in the system is damaged, the entire system is destroyed; in addition, if partition refrigeration is to be carried out, the current practice is that one compressor manages the refrigeration of one zone, which leads to equipment cost increase.

Summary of the invention

The purpose of the present invention is to provide an instant cooling system applied to drinking water. The instant cooling system uses a plate heat exchanger to realize the preparation of ready-to-use cold water, which is greatly improved compared to the traditional copper plate cooling method. In addition, this solution solves the technical problem that the plate heat exchanger will be damaged when the power is cut off accidentally, and further improves the application of the plate heat exchanger in the water dispenser.

The purpose of the present invention is to provide a zoned refrigeration system that only requires a compressor combined with a multi-way pipe to efficiently refrigerate different areas so that the refrigeration effect of each area is consistent. It is equipped with controls, temperature sensors and solenoid valves. , The use of temperature changes to control solenoid valves and compressors, so that the entire zoned refrigeration system can be efficient and stable, with a one-way valve to ensure one-way flow of vapor and prevent backflow and other phenomena.

In order to achieve any of the above objectives, the present invention provides an instant cooling system for drinking water, including a compressor, a plate heat exchanger, a water pump, a battery, and the refrigerant passage of the compressor is connected to the refrigerant passage of the plate heat exchanger. The cooling water path of the water pump is connected to the water circulation channel of the plate heat exchanger.

The present invention provides a partitioned refrigeration system, including: a compressor, a radiator, a reversing valve, a first partition assembly, a second partition assembly, and a refrigeration pipeline connected to each other; wherein the compressors are respectively connected to the first group assembly by pipelines , The second partition assembly and the radiator, the radiator pipeline connects the reversing valve, and the reversing valve pipeline connects the first partition and the second partition; wherein the first partition assembly includes the first refrigeration pipeline, and the second partition assembly includes The second refrigeration pipeline, the first refrigeration pipeline and the second refrigeration pipeline surround the materials in the first and second zones respectively, and exchange heat with the materials to complete the refrigeration

Compared with the prior art, this technical solution has at least the following technical effects:

1. The instant cooling system for drinking water equipped with a plate heat exchanger has a heat exchange area much larger than the heat exchange area of the outer wall of the copper tube under the same volume, and the flow channel gap of the plate heat exchanger is flat, and the gap between the water exchange body It is also much smaller than the diameter of the copper tube. Therefore, the refrigerant channel and the water circulation channel are alternately stacked to exchange the refrigerant with the water at the maximum efficiency and instantaneous heat exchange, so as to obtain the cold water at the water outlet of the water circulation channel.

2. Configure the battery. When the compressor is running, when at least one of the power supply, input power, and power input of the control terminal is out of power or fails, the battery will supply power to at least one of the control terminal and the water pump to ensure that the water circulation channel is always in circulating cooling. The state of the water circulation channel avoids the damage of the plate heat exchanger due to the volume expansion of the water in the water circulation channel.

3. The expansion chamber is located at any position of the pipeline at the inlet of the plate heat exchanger, and one of the embodiments inside or outside the expansion chamber is implemented with a heating device. The expansion chamber is a larger space at the end of the capillary tube, so that the release from the capillary tube The refrigerant can efficiently and completely evaporate and absorb heat. The heating device can stop the expansion chamber from continuing to cool down by starting the heating device after the compressor stops working or the cooling system is unexpectedly cut off, so as to avoid the water in the water circulation channel from stopping the flow of water. The expanded volume when icing causes damage to the plate heat exchanger.

4. The end of the capillary tube is directly connected to the expansion chamber, which reduces the connection between the capillary tube and the refrigerant channel through a thicker copper tube, and prevents the thicker copper tube from absorbing heat at the end of the capillary tube when the refrigerant changes from liquefaction to vaporization. The problem of road frosting reduces the waste of copper pipe materials and avoids the need to install thicker copper pipes with insulation materials.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of the present invention.

It can be understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in other embodiments, The number can be multiple, and the term "one" cannot be understood as a restriction on the number.

The technical solution provides an instant cooling system applied to drinking water. The instant cooling system uses a plate heat exchanger as an energy converter to realize the instant cooling effect of converting normal temperature water into cold water instantly, and the instant cooling system can be configured Switch the battery used and the optimized configuration of the battery can ensure that the plate heat exchanger can still operate normally when the instant cooling system is unexpectedly cut off, avoiding the damage of the plate heat exchanger due to internal icing and expansion.

It is worth mentioning that, unlike other equipment, the instant cooling system has special unexpected effects when used in a water dispenser or a beverage dispenser. The following takes the "water dispenser" as an example for illustration. First, because drinking fountains often need to transfer application scenarios according to the needs of the scene, second, most of the drinking fountains are powered by the external power supply of the place of use, and third, most of this type of drinking fountains are shared equipment shared by multiple people, or Placed in public places such as high-speed railway stations, and this feature makes the drinking fountains in a state of power failure during the transfer process or when the place is powered off, or the equipment is powered off due to misoperation, the plug falls off, and the contact is poor. The plate heat exchanger inside is very prone to problems such as icing, expansion and damage. In addition, the refrigerated water in the water dispenser is used for drinking, and the cooling method through the inside of the plate heat exchanger is more hygienic and safer than the traditional copper plate heat exchange method.

The instant cooling system for drinking water includes a plate heat exchanger 10, a refrigerant channel 11, a water circulation channel 12, a compressor 20, an expansion chamber 30 with a heating source, a water pump 40, a buffer cold storage container 50, a switching valve 60, and a control Terminal 70, battery 81, energy supply 82, input power 83, charging power 84, charging power supply 85, flow sensor 91, radiator 110, dryer 120, capillary tube 130, where the refrigerant path of compressor 20 is connected In the refrigerant passage 11 of the plate heat exchanger 10, the cooling water passage of the water pump 40 is connected to the water circulation passage 12 of the plate heat exchanger 10.

The refrigerant passage 11 in the plate heat exchanger 10 includes an inlet end and an outlet end of a refrigerant cycle, and the water circulation passage 12 includes an inlet end and an outlet end of water. The refrigerant passage 11 circulates refrigerant, and the water circulation passage 12 circulates. The flowing water realizes the instant cooling of the flowing water through the most direct heat exchange between the refrigerant and the flowing water.

However, the operation of the compressor 20 and the water pump 40 requires continuous external energy supply. In this technical solution, the control terminal 70 is electrically connected to the battery 81 and the water pump 40, and the power supply 82 and the input power supply 83 are connected to the control terminal 70, and then the control terminal 70 controls the start and stop of the compressor and the operation of the water pump 40, and the control terminal 70 is powered by the power supply 82, and the input power 83 provides power for the power supply 82, so that the instant cooling system operates normally. When the compressor 20 is running, when at least one of the power supply 82, the input power 83, and the power input of the control terminal 70 is powered off or fails, the battery 81 supplies power to at least one of the control terminal 70 and the water pump 40.

That is, when a power failure such as a power failure of the equipment, a plug falling off, or poor contact occurs due to misoperation, the battery 81 supplies power to the control terminal 70. At this time, the control terminal 70 continues to control the start and stop of the compressor and/or control the operation of the water pump 40; Alternatively, the battery 81 directly supplies power to the water pump 40 to ensure normal water circulation or flow.

Moreover, in this solution, the battery 81 can be selected as a charging cycle power supply, a dry battery, and a capacitor, that is, the battery 81 can be charged and stored through the charging power supply 84.

In this solution, it is not only necessary to prevent the plate heat exchanger 10 from freezing and expanding, but also to consider the condition of the conveying pipeline. Therefore, in this technical solution, the compressor 20 is connected to the plate heat exchanger 10 through a capillary tube 130 to cool The inlet of the agent channel 11 is provided with an expansion chamber 30, and the end of the capillary tube 130 is directly connected to the expansion chamber 30 or at least one of the expansion chamber 30 is connected through the extension tube of the capillary tube 130.

Since the refrigerant will undergo a phase change from liquefaction to vaporization when it comes out of the end of the capillary tube, it will absorb a lot of heat at the moment of the phase change. When the copper pipe is used for traditional connection, the outside of the copper pipe is prone to frost and defrost, and it is easy to accumulate water. This leads to damage to the instant cooling system.

The expansion chamber 30 is located at any position of the pipeline of the inlet of the plate heat exchanger 10, and the expansion chamber 30 has a heating heat source, wherein the heating heat source is heated by at least one of electric heating, infrared heating, electromagnetic heating, and heat conduction by the heat source.

The heating source has at least the following two functions:

1. When the instant cooling system is in normal cooling, when the compressor 20 is instructed to stop cooling, the water pump 40 can also end the operation at the same time. At this time, the heat from the heating source will block the cold entering the refrigerant inlet. This cold energy is generated because although the compressor 20 has stopped working, there is still refrigerant in the pipeline, and the refrigerant still releases cold energy. At this time, this part of the cold energy can be prevented from entering the plate heat exchanger by heating the heat source Damage to the plate heat exchanger.

2. When the instant cooling system is in an unexpected power failure, the heating source heats up the refrigerant inlet of the plate heat exchanger 10, blocking the cold energy from entering the plate heat exchanger.

In addition, in some embodiments, the instant cooling system includes a buffer cold storage container 50, wherein one end of the buffer cold storage container 50 is connected to the water pump 40, and the other end is connected to the water circulation channel 12 of the plate heat exchanger 10. At this time, the water pump 40 is connected to any position of the water circulation channel 12. Preferably, the inlet of the water pump 40 is connected to the water circulation channel 12; the cold buffer storage container 50 is connected to any position of the water circulation channel 12, preferably, the buffer cold storage container 50 is connected to the water circulation channel 12 The water inlet.

The buffer cold storage container 50 has at least the following functions in the instant cooling system:

1. Under special circumstances, the water pump 40 can directly draw cold water from the buffer cold storage container 50 and output it for use.

2. When other pumps or water sources supply water to the cold buffer storage container 50, or when the water temperature in the cold buffer storage container 50 is not low enough, the semi-cold water in the cold buffer storage container 50 can exchange heat through the plate heat exchanger 10 After being refrigerated, it is stored in the buffer cold storage container 50 or exported for use.

In addition, the outlet pipe of the water pump 40 is connected to a switching valve 60. At least one switching valve 60 is placed between the water pump 40 and the buffer cold storage container 50. The other end of the switching valve 60 is connected to other water ports. When multiple switching valves are used, The inlet water source of the water circulation channel 12 is used to buffer the switching between the cold storage container 50 and the normal temperature water source through at least one switching valve or at least two on-off valves.

In addition, in some embodiments, the switching valve 60 is replaced or supplemented by more than one on-off valve. In other words, the switching valve 60 may include an on-off valve and a combination of an on-off valve and a shut-off valve.

In order to better monitor the buffer cold storage container 50, the instant cooling system includes a water level sensor 92 and a temperature sensor 93. The water level sensor 92 is placed in the buffer cold storage container 50, and the temperature sensor 93 is placed in the buffer cold storage container 50 or connected To the pipeline of the buffer cold storage container 50.

In addition, a flow sensor 91 is provided at any position in the water circulation channel 12 and the water pump 40. Preferably, the flow sensor 91 is placed at any position of the pipeline at the front end of the water inlet of the water pump 40.

The control terminal 70 includes at least one switch. The trigger of the switch is whether the voltage and current of the power supply 82 are normal. When it is abnormal, the battery 81 is connected to supply power to the water pump 40. The switch is an external accessory. It is a component integrated with other components, and is at least one of the main body components integrated with the control terminal 70.

Specifically, the compressor 20 compresses the refrigerant to filter impurities and moisture through the dryer 120, and stores energy and pressurizes through the capillary tube 130. The end of the capillary tube instantly vaporizes and absorbs heat in the expansion chamber 30, and extremely low refrigerant gas instantly flows through the refrigerant channel. 11. After absorbing the temperature of the flowing water in the water circulation channel 12, it dissipates heat through the radiator 110, and is compressed again by the compressor 20 and cyclically cooled. The cooled flowing water in the water circulation channel 12 is pumped out by the water pump 40 for use, or pumped into the buffer cold storage container 50 through the switching valve 60 for storage, or circulated to cool the colder water. When the water temperature is the water temperature of the general cooling capacity, the switching valve switches the water inlet water source of the water circulation channel 12 to the normal temperature water source. When the water temperature in the buffer cold storage container 50 is not enough for the water demand of lower temperature, the water pump 40 switches from the buffer cold storage The container 50 is refrigerated by the plate heat exchanger 10 and then pumped out for use. The buffer cold storage container 50 can also be continuously cooled by the plate heat exchanger 10 to make the water in the buffer cold storage container 50 achieve a specified low temperature.

In this solution, as long as the compressor 20 is in operation or about 2 minutes after the compressor is stopped, the water temperature of the water circulation channel 12 must be flowing, and when an unexpected power failure occurs, the power supply 82, the input power (83), When at least one of the power input functions of the control terminal 70 is powered off or fails, the battery 81 supplies power to at least one of the control terminal 70 and the water pump 40, and the logical relationship here can be selected as follows;

1. When the control terminal 70 detects or supplies the power supply 82, the input power supply 83, and the control terminal 70 power supply is out of power, the input function is abnormal or the voltage input voltage is lower than the voltage of the battery 81, the battery 81 continues to supply power to the control terminal 70, and the control terminal The water pump 40 and the switching valve are controlled to maintain the circulating flow of the water circulation channel 12 until a fixed time or the temperature sensor 93 stops running when the specified command parameter is reached.

2. When the control terminal 70 detects or supplies the power supply 82, the input power supply 83, the power supply of the control terminal 70 is out of power, the input function is abnormal or the voltage input voltage is lower than the voltage of the battery 81, the battery 81 maintains the water pump 40 and switches through the switch 60 The valve 60 maintains the circulating flow of the water circulation channel 12 until a fixed time or the temperature sensor 93 stops operating when the specified command parameter is reached.
