Description

[Technical field]

[0002] The utility model relates to the technical field of rapid refrigeration adapted to pipeline fluid, in particular to the technical field of cold storage type rapid refrigeration. [Background technology]

[0004] As living standards improve, the demand for cold water, cold drinks, and ice wine machines is gradually increasing to meet people's need to take frozen drinks at any time. In addition, the demand for miniaturized refrigeration equipment is gradually becoming apparent, so that it can be adapted to various spaces as needed instead of requiring a large space to be used. However, current refrigeration technology and refrigeration equipment have their own advantages and disadvantages:

[0005] The first type: using refrigeration tanks for refrigeration. The equipment needs to be equipped with a freezing tank. The water that meets the drinking demand is injected into the cold tank to make cold water. However, the cold tank is prone to secondary pollution if it is not used for a long time. Our common ice wine machine completes the refrigeration and cooling process by configuring a cold tank.

[0006] When using a cold tank, the cold water utilization rate is generally 50%-60%, which means that when 500ml of cold water is needed, the volume needs to be 800-1000ml, and the actual volume is wasted a lot.

[0007] The second category: instant cooling technology refrigeration. The compressor required in instant cooling technology has high power, high cost, high noise, and can only provide instant cooling of a smaller flow rate. If large-flow instant cooling is required, additional high-power refrigeration equipment must be configured. High-power refrigeration equipment is large in size, difficult to manufacture, and expensive, and is not suitable for use in ordinary household scenarios.

[0008] In the existing technology, the cold storage refrigeration technology is considered to be applied to the household refrigeration system, and the cold storage method is to consider using phase change materials for cold storage. Phase change materials refer to substances that change the state of matter and provide latent heat when the temperature remains unchanged. The process of changing physical properties is called phase change process, and at this time, the phase change material will absorb or release a large amount of latent heat. [Summary of the invention]

[0010] In view of the shortcomings of existing refrigeration equipment and the defects of being unsuitable for household and miniaturized use, the utility model proposes a cold storage refrigeration system suitable for pipeline fluids. The system uses phase change materials as cold storage carriers to perform refrigeration storage during idle time, and then quickly reduces the temperature of drinking water flowing through the pipeline through the principle of heat exchange to achieve a rapid cooling effect. At the same time, it does not require a high-power compressor and can greatly reduce the size of the equipment, which is suitable for household scenes and space requirements.

[0011] The pipeline fluid cold storage type rapid refrigeration system involved in the utility model includes a water inlet, a water pump, a thermometer, a refrigeration component, an electric control board and a water outlet, and is characterized in that the system also includes a phase change refrigeration unit, which includes a shell, a heat exchanger, a phase change material and a refrigeration component, wherein the phase change material is filled between the heat exchanger and the shell, and the refrigeration component is built-in inside the shell. The setting of the refrigeration component is based on its ability to store cold for the phase change material, and the water pump draws water from the water inlet and connects to the water outlet through the phase change refrigeration unit.

[0012] The phase change refrigeration unit is provided with a flow channel communicating with the heat exchanger, which is connected from the water inlet through the flow channel in the heat exchanger to the water outlet.

[0013] The thermometer comprises a unit thermometer and a water outlet thermometer, wherein the unit thermometer is arranged in the shell of the phase change refrigeration unit, and the water outlet thermometer is arranged at the water outlet.

[0014] The phase change material is selected to have a phase change temperature range of -15°C to 10°C and an enthalpy value greater than 200 J / g.

[0015] Furthermore, the best choice is to select a phase change material with a phase change temperature of 5°C.

[0016] The module thermometer and the outlet water thermometer are infrared thermometers, NTC thermometers or thermocouple thermometers.

[0017] The pipeline fluid cold storage rapid refrigeration system involved in the utility model adopts phase change material as a cold storage carrier, performs refrigeration storage during idle time, and then rapidly reduces the temperature of drinking water flowing through the pipeline through the heat exchange principle to achieve a rapid cooling effect. At the same time, it does not require a high-power compressor, and can greatly reduce the size of the equipment design, which is suitable for home scenes and space requirements.

[0024] The pipeline fluid cold storage type rapid refrigeration system involved in the utility model is aimed at the existing refrigeration equipment, which either uses a cold tank for refrigeration or needs to use a large compressor to achieve the effect of rapid refrigeration. A pipeline fluid cold storage type rapid refrigeration system with a small volume suitable for home use is proposed. First, a cold tank is no longer used, but a pipeline is used to directly cool the liquid flowing through the pipeline. It is a method of cooling immediately after passing through, which completely avoids secondary pollution. The method adopted uses phase change materials in the system for heat exchange to cool. In this technical solution, phase change materials with a phase change temperature range of -15℃~10℃ and an enthalpy value greater than 200J / g are preferred. Taking water as an example, the energy required to release water from 25℃ to 10℃ is 42J / g, so 1g of phase change material can output more than 4.7g of cold water. It is obvious that the volume occupied by the design of the system can be greatly reduced.

[0025] The pipeline fluid cold storage type rapid refrigeration system involved in the utility model includes a water inlet 10, a water pump 20, a thermometer, a refrigeration component 30, an electric control board and a water outlet 40, characterized in that the system also includes a phase change refrigeration unit 50, the phase change refrigeration unit 50 includes a shell 51, a heat exchanger 52, a phase change material (not shown) and a refrigeration component, wherein the phase change material is filled between the heat exchanger 52 and the shell 51, and the refrigeration component 30 is built inside the shell 51. The setting of the refrigeration component 30 is based on its ability to store cold for the phase change material. In actual industrial production, the refrigeration component 30 can be covered on the heat exchanger 52 or pasted on the shell 51, as long as it can be designed to refrigerate the phase change material. The water pump 20 draws water from the water inlet 10 and connects to the water outlet through the phase change refrigeration component 30.

[0026] The phase change refrigeration unit 50 is provided with a flow channel connected to the heat exchanger 52 , which is connected from the water inlet 10 through the flow channel in the heat exchanger 52 to the water outlet 40 .

[0027] The thermometer includes a unit thermometer 11 and a water outlet thermometer 12 , wherein the unit thermometer 11 is disposed in a housing of the phase change refrigeration unit 50 , and the water outlet thermometer 12 is disposed at the water outlet 40 .

[0028] The phase change material is selected to have a phase change temperature range of -15°C to 10°C and an enthalpy value greater than 200 J / g.

[0029] Furthermore, the best choice is to select a phase change material with a phase change temperature of 5°C.

[0030] The module thermometer 11 and the outlet water thermometer 12 are infrared thermometers, NTC thermometers or thermocouple thermometers.

[0031] Embodiment 1:

[0032] When the object to be refrigerated is wine, the system preferably uses a phase change material with a phase change point of -10~0℃. When the system is not working, the refrigeration component 30 is started to use electrical energy for energy storage and refrigeration, and the phase change material is cooled to -10~0℃. Since the transport water is easy to freeze when cooled to -10~0℃, the system that selects a phase change material with a phase change point of -10~0℃ that is specially suitable for refrigerating wine, pumps the wine to the phase change energy storage module for heat exchange, which is actually to refrigerate the wine passing through the heat exchanger, and control the temperature of the wine by controlling the flow of the water pump.

[0033] Embodiment 2:

[0034] In this embodiment, the biggest difference from Embodiment 1 is that a phase change material with a phase change point of 0-10°C is preferred. At this time, the system is specially designed for cooling water. Because water freezes at 0°C, in order to avoid freezing of water and not flowing due to refrigeration, a phase change material with a phase change temperature of 0-10°C is specially selected; when cooling water is needed, the raw water / clean water is transported to the phase change energy storage module through a water pump for cooling, and the outlet water temperature is controlled by controlling the flow rate of the water pump.

[0035] The pipeline fluid cold storage rapid refrigeration system involved in the utility model adopts a phase change material with a high enthalpy value as a cold storage carrier, performs refrigeration storage during idle time, and then rapidly reduces the temperature of drinking water flowing through the pipeline through the heat exchange principle, thereby achieving a rapid cooling effect and avoiding secondary water pollution. At the same time, it does not require a high-power compressor, and can greatly reduce the size of the equipment design, which is suitable for home scenes and space requirements.

[0036] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model.
