[0043] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present invention.

[0044] Please refer to the drawings of the present invention Figure 1 - the drawings of the present invention Figure 2 The embodiments of the present invention provide a double-cycle energy-saving refrigeration system with waste heat recovery function, which includes:

[0045] The first refrigeration cycle module is used to perform the main refrigeration task, including a compressor, a condenser, an expansion valve, and an evaporator, which realizes the refrigeration effect through the circulation of refrigerant;

[0046] The first and second refrigeration cycle modules use different refrigerants to optimize their respective refrigeration effects and energy efficiencies.

[0047] The second refrigeration cycle module, connected in parallel with the first refrigeration cycle module, is used for auxiliary refrigeration and waste heat recovery, including an auxiliary compressor, an auxiliary condenser, an auxiliary expansion valve, and an auxiliary evaporator.

[0048] Specifically, efficient refrigeration and waste heat recovery are achieved through two parallel refrigeration cycle modules. The first refrigeration cycle module undertakes the main refrigeration task, including key components such as a compressor, a condenser, an expansion valve, and an evaporator. The compressor compresses the refrigerant into high-temperature and high-pressure gas, which then releases heat in the condenser to condense into liquid. After that, the liquid passes through the expansion valve to reduce pressure and temperature, and finally evaporates in the evaporator to achieve the refrigeration effect. To further improve the energy efficiency and refrigeration effect of the system, the first and second refrigeration cycle modules use different refrigerants, which can be optimized for their respective working conditions.

[0049] The second refrigeration cycle module works in parallel with the first refrigeration cycle module, assisting the first refrigeration cycle module in refrigeration and recovering the waste heat released in the condenser of the first refrigeration cycle module. This module includes an auxiliary compressor, an auxiliary condenser, an auxiliary expansion valve, and an auxiliary evaporator, which work similarly to the first refrigeration cycle module but are mainly used for waste heat recovery and reuse, improving overall energy efficiency. Through this dual-cycle design, the system can effectively recover and utilize waste heat while ensuring refrigeration effect, achieving efficient energy utilization.

[0050] The waste heat recovery module is connected to the condenser of the first refrigeration cycle module and the auxiliary condenser of the second refrigeration cycle module, used to recover the waste heat generated by the first refrigeration cycle module and use it for the preheating process of the second refrigeration cycle module.

[0051] The waste heat recovery module includes:

[0052] The heat exchanger is used to exchange heat between the condenser of the first refrigeration cycle module and the auxiliary condenser of the second refrigeration cycle module, transferring the waste heat generated by the first refrigeration cycle module to the second refrigeration cycle module.

[0053] The thermal energy storage unit is used to store the recovered waste heat for use when needed.

[0054] The thermal energy converter is used to convert the recovered waste heat into electrical energy or other forms of usable energy.

[0055] Specifically, the waste heat recovery module recovers and reuses the waste heat released in the condenser of the first refrigeration cycle module through an efficient heat exchange process. This module is directly connected to the condenser of the first refrigeration cycle module and the auxiliary condenser of the second refrigeration cycle module, ensuring that the waste heat can be effectively transferred from a high-temperature environment to a low-temperature environment for preheating the refrigerant in the second refrigeration cycle module.

[0056] The waste heat recovery module internally contains three key components: a heat exchanger, a thermal energy storage unit, and a thermal energy converter. The heat exchanger is responsible for heat exchange between the two refrigeration cycle modules, transferring the waste heat generated by the first refrigeration cycle to the second refrigeration cycle module, thereby reducing energy waste and improving the overall energy efficiency of the system. The thermal energy storage unit is used to temporarily store these recovered waste heat for use when the system needs it, ensuring stable energy supply. Finally, the thermal energy converter converts the recovered waste heat into electrical energy or other forms of usable energy, further increasing the energy utilization efficiency of the system, so that the heat energy that would otherwise be wasted can be effectively utilized to provide additional energy sources for the system or for other purposes. In this way, the waste heat recovery module not only improves the energy utilization efficiency of the refrigeration system, but also helps to reduce operating costs and environmental impact.

[0057] The waste heat recovery module also includes:

[0058] A temperature regulation unit for adjusting the temperature of the recovered waste heat to ensure it is within the appropriate range for preheating or energy conversion;

[0059] A flow control unit for controlling the flow of waste heat to optimize heat exchange efficiency.

[0060] Specifically, the waste heat recovery module is further equipped with a temperature regulation unit and a flow control unit to enhance the system's thermal management capabilities and improve heat exchange efficiency. The role of the temperature regulation unit is to fine-tune the temperature of the recovered waste heat, ensuring that the waste heat is effectively utilized within the appropriate temperature range, whether for preheating the second refrigeration cycle module or for energy conversion through the energy conversion module.

[0061] At the same time, the flow control unit is responsible for precisely managing the flow of waste heat by adjusting the flow rate of waste heat in the heat exchanger to achieve more efficient heat exchange. Optimized flow control can ensure that the heat exchanger operates in the best state, maximizing the recovery and utilization of thermal energy while reducing energy loss. The coordinated work of these two units enables the waste heat recovery module to adapt flexibly to different operating conditions, improving the stability and reliability of the system, further enhancing the energy-saving effect and environmental friendliness of the system.

[0063] The energy conversion module includes:

[0064] An organic Rankine cycle system for converting the recovered waste heat into electrical energy, improving the energy recovery efficiency of the system;

[0065] A heat pump system for raising the recovered waste heat to a higher temperature for heating or other purposes.

[0066] Specifically, the energy conversion module is connected to the waste heat recovery module and is responsible for converting the recovered waste heat into usable thermal or electrical energy, thereby significantly improving the overall energy efficiency of the system. This module includes two main parts: an organic Rankine cycle system and a heat pump system. The organic Rankine cycle system generates steam by utilizing waste heat, driving a turbine to generate electricity, directly converting thermal energy into electrical energy, which not only improves energy recovery efficiency but also provides additional power to the system. On the other hand, the heat pump system raises the recovered waste heat to a higher temperature, enabling it to be used for space heating, hot water supply or other thermal energy needs, increasing the utilization of waste heat. Through this diversified energy conversion mode, the energy conversion module greatly improves the energy utilization efficiency of the system, reduces the dependence on external energy, and realizes the recycling of energy.

[0067] The energy conversion module also includes:

[0068] An energy storage unit for storing converted electrical energy or other forms of energy for use when needed;

[0069] An energy management system for intelligently distributing and managing stored energy, improving the overall energy efficiency of the system.

[0070] Specifically, the energy conversion module not only contains an organic Rankine cycle system and a heat pump system, but also integrates an energy storage unit and an energy management system to maximize energy conversion and utilization. The role of the energy storage unit is to store the electrical energy or other forms of energy generated by the energy conversion module, ensuring that the system can accumulate energy when energy production exceeds immediate demand, and release energy when energy demand peaks or production is insufficient, thereby balancing the energy supply and demand of the system, improving the flexibility and reliability of energy utilization. The energy management system is responsible for intelligently distributing and managing these stored energies. It optimizes energy use and scheduling by monitoring the energy status of the system and predicting demand in real time, ensuring that energy is effectively utilized when it is most needed, further improving the overall energy efficiency and operational economy of the system. The combination of these two components enables the energy conversion module not only to improve the conversion efficiency of waste heat, but also to enhance the system's control and regulation capabilities of energy.

[0071] The control module is connected with the first refrigeration cycle module, the second refrigeration cycle module, the waste heat recovery module and the energy conversion module, and is used for intelligently adjusting operation parameters of each module according to a running state and an environmental condition of the system, so as to optimize energy efficiency and performance of the system.

[0075] Specifically, the control module can intelligently adjust operation parameters of each module according to a real-time running state and an external environmental condition by being connected to the first refrigeration cycle module, the second refrigeration cycle module, the waste heat recovery module and the energy conversion module, so as to optimize overall energy efficiency and performance of the system. The control module internally integrates a sensor network, which is responsible for monitoring key operation parameters such as temperature, pressure and flow rate in real time, so as to ensure that the system runs in an optimal state. A microprocessor receives data from the sensor network and analyzes and processes the data by using advanced algorithms, so as to make accurate control decisions. The intelligent adjustment capability of the microprocessor enables the system to adapt to different working conditions and load changes, automatically adjusts a running strategy, so as to achieve higher energy efficiency and better performance. The intelligent control mechanism not only improves an automation level of the system, but also enhances flexibility and adaptability of the system, so as to ensure stable running and high energy efficiency of the system.

[0076] A communication interface is used for data communication with external equipment, so as to realize remote monitoring and diagnosis.

[0077] The control module further comprises:

[0078] A fault diagnosis unit is used for monitoring a running state of the system in real time, diagnosing potential faults and issuing an alarm;

[0079] An adaptive control unit is used for automatically adjusting operation parameters of each module according to a running state and an environmental condition of the system, so as to optimize energy efficiency and performance of the system.

[0080] Specifically, the control module further integrates the fault diagnosis unit and the adaptive control unit, so as to enhance an intelligent level and running reliability of the system. The fault diagnosis unit is responsible for monitoring a running state of the entire system in real time, identifies any abnormal situation or potential fault by analyzing data from the sensor network, and timely issues an alarm when a problem is detected. This helps to discover and solve possible problems of the system in advance, so as to avoid further development of the fault, reduce downtime and maintenance cost.

[0081] The adaptive control unit automatically adjusts the operating parameters of the first refrigeration cycle module, the second refrigeration cycle module, the waste heat recovery module, and the energy conversion module according to the real-time operating state of the system and external environmental conditions. This adaptive adjustment capability enables the system to flexibly respond to different working conditions and load changes, optimizing the operating efficiency of each module and improving the overall energy efficiency and performance of the system. Through intelligent adjustment, the adaptive control unit ensures that the system always operates in the optimal way, achieving higher energy utilization efficiency and better refrigeration effect while reducing energy consumption and operating costs. The combination of these two units significantly improves the intelligence level, reliability, and adaptability of the system, providing users with an efficient, stable, and energy-saving refrigeration solution.

[0087] Specifically, the user interface, remote monitoring module, security module, and environmental monitoring unit collectively constitute the auxiliary function modules of the system, aiming to improve user experience, system security, and operating reliability. The user interface provides an intuitive operation platform, displaying key system operating states and fault diagnosis information, allowing users to real-time understand system performance and input operation instructions to adjust system settings as needed. The remote monitoring module allows users to remotely access the system through the network, enabling monitoring and diagnosis of the refrigeration system regardless of the user's location. The security module protects the system from data leakage and unauthorized access risks, ensuring the safe operation of the system.

[0088] Working principle: The first refrigeration cycle module is responsible for the main refrigeration task. It compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas through the compressor, then releases heat in the condenser to cool into liquid, and absorbs heat in the evaporator to achieve refrigeration after throttling and pressure reduction by the expansion valve. The second refrigeration cycle module is connected in parallel with the first refrigeration cycle module, used for auxiliary refrigeration and waste heat recovery. Its working principle is similar to the first refrigeration cycle module, but it is connected to the condenser of the first refrigeration cycle module through the waste heat recovery module to transfer the waste heat generated by the first refrigeration cycle module to the second refrigeration cycle module for preheating or energy conversion. The heat exchanger in the waste heat recovery module realizes heat energy transfer, the heat energy storage unit stores the recovered waste heat, and the heat energy converter converts the waste heat into electrical energy or other forms of useful energy.
