[0002] At present, existing refrigerated vehicles rely on internal combustion engines, generators and other components to maintain the low temperature inside the box, which is not only costly but also involves complex maintenance issues. There are problems in cold chain logistics such as cold loss, insufficient heat exchange capacity of condensers, poor insulation effect and unstable structure of mobile cold storage.

[0003] The Chinese patent with publication number CN112954024A discloses a remote intelligent management system for refrigerated containers, including a refrigerated cabinet management system and a remote server management system bidirectionally connected to the refrigerated cabinet management system through a mobile wireless network; the refrigerated cabinet management system is bidirectionally electrically connected to the refrigeration control module, the anti-theft monitoring module, and the driving record module. The refrigerated container management system is responsible for controlling the refrigeration and temperature of the refrigerated container, and collecting the status of the refrigeration unit, the battery status, the temperature status of the box, and the disinfection, moisturizing and other controls; at the same time, it collects monitoring videos, door opening anti-theft records, vehicle information, location and other information, and uploads them to the remote server management system for storage and archiving, waiting to be retrieved at any time; the remote server management system and the client terminal, in addition to basic functions such as interface and authorization, also send refrigerated container data to the terminal according to the authorization level, and illustrate the current status and results of the refrigerated container on the terminal.

[0004] Although this method can be used for cold storage management, due to cold loss and insufficient heat exchange capacity of the condenser during the cold storage process, more energy is needed for refrigeration and cold storage, which is very costly. It cannot meet the existing large-scale transportation refrigeration, cannot adapt to the cold energy management needs of different scales, and cannot freely choose the operation mode.

[0017] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] See also Figure 1 The present invention provides a technical solution: a mobile cold energy management system based on replacement, comprising at least one mobile cold energy unit, each unit comprising a cold energy generation module, a cold energy storage module and a cold energy release module, wherein the cold energy generation module is connected to the cold energy storage module, and the cold energy storage module is connected to the cold energy release module.

[0021] One side of each mobile cold energy unit is connected to a control and monitoring unit, which in turn is connected to an electric energy control unit. The control and monitoring unit operates based on an AI algorithm, and can effectively manage and optimize the use of cold energy under different external temperature conditions, and automatically adjust the freezing and release of phase change materials to maximize energy efficiency. The electric energy control unit includes multiple sets of low-temperature resistant battery packs, which are optimized for low-temperature environments and support the operation of system electronic equipment. The multiple sets of low-temperature resistant battery packs are supplied by abandoned wind and solar energy in surrounding areas.

[0022] The cold energy generating unit includes a refrigerator, which uses dual semiconductor refrigeration to achieve refrigeration through the temperature difference between the P-type and N-type semiconductors of the semiconductor material. The dual semiconductor refrigeration technology uses the thermoelectric effect. The thermoelectric effect refers to the fact that in some materials, when there is a voltage difference between two contact surfaces at different temperatures, a temperature difference between the cold and hot sides will be generated. The dual semiconductor refrigeration technology utilizes this effect to achieve a refrigeration effect through current and heat exchange, and is used to generate cold air.

[0023] Phase change materials are used in the cold energy storage module. Phase change materials refer to materials that undergo structural phase changes at a specific temperature due to external stimuli (such as temperature, pressure, electric field, etc.). Phase change materials have a very wide range of applications, including electronic devices, sensors, energy storage and conversion, etc. PCM (Phase Change Energy Storage Material): PCM is a material that can absorb and release a large amount of heat and is widely used in fields such as construction, automobiles, and electronic equipment.

[0024] In the dual semiconductor refrigeration system, the P-type and N-type semiconductors correspond to the hot side and the cold side respectively. When current passes through the semiconductor, the P-type semiconductor on the hot side absorbs heat, and the N-type semiconductor on the cold side releases heat, forming a heat flow under the action of the current. In this way, the cooling effect of absorbing heat from one side and releasing heat on the other side is achieved.

[0025] Compared with traditional refrigeration technology, dual semiconductor refrigeration has the following advantages: First of all, it is highly efficient and energy-saving. Dual semiconductor refrigeration technology does not require the use of refrigerants, reduces the number of components and energy conversion processes in the refrigeration system, and therefore has higher refrigeration efficiency, which can better meet the needs of energy conservation and environmental protection.

[0026] Secondly, it is environmentally friendly and pollution-free. Since no refrigerant is needed, the dual semiconductor refrigeration technology does not have the problem of refrigerant pollution to the environment. At the same time, there is no flow of liquid or gas in the refrigeration process, which reduces damage to the atmosphere.

[0027] The second is silent operation. The dual semiconductor refrigeration equipment uses a non-mechanical motion method, without the noise sources such as compressors and fans in traditional refrigeration equipment, and the operation is very quiet.

[0028] Phase change materials enable refrigeration at night or during times when electricity prices are lower, utilizing energy cost-effectively.

[0029] The cold energy release unit includes an air conditioning module for converting the stored cold energy into required cold air or other forms of energy for use.

[0030] The mobile cooling unit can be transferred via a vehicle, and the overall installation is convenient.

[0031] The control and monitoring unit includes a sensor, a controller and a user interface. The sensor is used to monitor the status of the cold energy unit. The controller makes decisions based on feedback information from the sensor. The user interface provides an interface for human-computer interaction, thereby improving the overall monitoring sensitivity and accuracy and realizing intelligent management of the entire system.

[0032] The mobile cooling units can be combined or split according to actual needs to adapt to cooling energy management needs of different scales, and each unit can operate independently.

[0033] In addition, the thermal energy storage of the phase change material is calculated as follows: Q = m * L Where Q is the stored heat, m is the mass of the phase change material, and L is the latent heat of phase change.

[0034] Estimated cooling efficiency: E=Q1 / Q2*100% Among them, Q1 is the actual heat used, and Q2 is the stored heat. Through this calculation, the system can evaluate the efficiency of cold energy use and make optimal adjustments.

[0035] The specific usage and function of this embodiment are as follows: S1. Multiple low-temperature resistant battery packs in the power control unit are optimized for low-temperature environments to support the operation of system electronic equipment. The abandoned wind and solar power in the surrounding areas are provided to multiple low-temperature resistant battery packs to reduce costs. The energy is then provided from the power control unit to each mobile cooling unit and the control and monitoring unit to ensure overall continuous monitoring.

[0036] S2. During the cold transport process, the control and monitoring unit will monitor the status of the cold energy unit through sensors. The controller will make decisions based on the feedback information from the sensors. The user interface provides an interface for human-computer interaction to improve the overall monitoring sensitivity and accuracy, and is used to monitor information at the terminal.

[0037] S3. Under the action of the mobile cold energy unit, a dual semiconductor refrigeration method is used. When current passes through the semiconductor, the P-type semiconductor on the hot side absorbs heat, and the N-type semiconductor on the cold side releases heat. Under the action of the current, a heat flow is formed, achieving a cooling effect of absorbing heat from one side and releasing heat on the other side. No refrigerant is required, which is more energy-saving and environmentally friendly.

[0038] S4. Finally, the phase-changing material is used to store cold energy, and then the air-conditioning module is used to convert the stored cold energy into the required cold air or other forms of energy for use.

Some or all of the modules may be selected according to actual needs to achieve the purpose of the scheme of this embodiment. Ordinary technicians in this field can understand and implement it without paying creative labor.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
