[0002] With increasing global environmental awareness, the requirements for the environmental friendliness of air conditioning refrigerants are becoming increasingly stringent. Some refrigerants used in traditional air conditioners have high GWP (Global Warming Potential), which can have adverse effects on the ozone layer and global climate. Meanwhile, in practical use, air conditioners often face a contradiction between the need for rapid cooling and energy consumption. How to reduce energy consumption while ensuring rapid cooling has become an important direction for the development of current air conditioning technology.

[0003] Existing air conditioning systems either prioritize rapid cooling while neglecting energy consumption, leading to energy waste, or sacrifice cooling speed to reduce energy consumption, failing to meet users' immediate needs. Summary of the Invention

The refrigeration cycle unit is used to realize the circulation of low-GWP refrigerant to complete the refrigeration process, and the refrigerant management unit is used to control the flow rate and state of low-GWP refrigerant. Refrigerant with a GWP value of less than 150 circulates within the core refrigeration module.

[0008] An enhanced heat exchange module is connected to the heat exchange end of the core refrigeration module to enhance the heat exchange efficiency between the refrigeration cycle unit and the indoor air, so as to achieve rapid cooling. The enhanced heat exchange module can adjust the heat exchange intensity according to the refrigeration demand.

[0009] The intelligent control center establishes control connections with the core cooling module and the enhanced heat exchange module respectively. It can dynamically adjust the cooling output of the core cooling module and the operating intensity of the enhanced heat exchange module according to the difference between the indoor temperature and the target temperature, thereby improving the cooling and heat exchange efficiency during the rapid cooling phase and reducing energy consumption when approaching the target temperature.

[0010] Furthermore, the enhanced heat exchange module includes a heat conduction enhancement unit and an airflow drive module. The heat conduction enhancement unit forms an efficient heat transfer connection with the heat exchange end of the core refrigeration module. The airflow drive module is used to accelerate the speed of air flowing through the heat exchange end, and the operating parameters of the airflow drive module can be adjusted by the intelligent control center.

[0011] Furthermore, the heat conduction enhancement unit includes a heat transfer substrate and a heat dissipation enhancement structure. The heat transfer substrate is closely attached to the heat exchange end of the core refrigeration module to quickly conduct heat, and the heat dissipation enhancement structure is used to increase the contact area with air and improve the heat dissipation efficiency.

[0012] Furthermore, the airflow drive module includes a power drive unit and an airflow pushing structure. The power drive unit is electrically connected to the intelligent control center and receives control commands to adjust the operating state. The airflow pushing structure, driven by the power drive unit, promotes airflow and accelerates heat exchange.

[0013] Furthermore, the intelligent control center includes:

[0014] The environmental sensing module can collect indoor environmental parameters, refrigeration system operating parameters, and air status parameters in real time;

[0015] The decision control unit establishes a data transmission channel with the environmental perception module and has a built-in adaptive adjustment algorithm that can generate control strategies based on the collected parameters.

[0016] The execution adjustment module forms a control connection with the decision control unit, the core refrigeration module, and the enhanced heat exchange module, and adjusts the operating parameters of each module according to the control strategy.

[0017] Furthermore, it also includes a scene adaptation module, which interacts with the intelligent control center to modify the control strategy of the intelligent control center based on indoor space characteristics, personnel activities, and outdoor environmental conditions, so as to reduce ineffective energy consumption.

[0018] Furthermore, the refrigerant management unit of the core refrigeration module is connected to the intelligent control center, which can increase the refrigerant circulation volume during the rapid cooling phase and reduce the circulation volume when approaching the target temperature, thereby improving refrigerant utilization efficiency.

[0019] Furthermore, the heat conduction enhancement unit also includes a thermal resistance reduction structure, which is disposed between the heat transfer substrate and the heat exchange end of the core refrigeration module to reduce contact thermal resistance and accelerate heat transfer.

[0020] Furthermore, the adaptive adjustment algorithm of the decision control unit includes a self-learning function, which can record the optimal operating parameters under different usage scenarios, continuously optimize the control logic, and improve system performance.

[0021] Furthermore, the low-GWP refrigerant is an environmentally friendly refrigerant with good thermal stability and fluidity, which can be adapted to various parts of the core refrigeration module to ensure efficient and stable system operation.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] Firstly, the enhanced heat exchange module plays a crucial role in this invention. The heat transfer substrate of the heat conduction enhancement unit is tightly fitted to the evaporator of the core refrigeration module. The heat dissipation enhancement structure increases the contact area with air, and the thermal resistance reduction structure reduces contact thermal resistance, significantly improving heat transfer efficiency. The power drive unit 221 of the airflow drive module drives the airflow pushing structure 222, which can flexibly adjust the airflow speed according to cooling needs. These two components work together, and the core refrigeration module increases the refrigerant circulation through the refrigerant management unit during the rapid cooling phase, enabling the system to quickly reduce indoor temperature, meeting users' immediate cooling needs and significantly improving the user experience.

[0024] Secondly, the intelligent control center of this invention generates a control strategy based on the difference between the indoor temperature and the target temperature collected by the environmental sensing module. This strategy is then generated by the adaptive adjustment algorithm of the decision control unit. The execution adjustment module dynamically adjusts the cooling output of the core cooling module and enhances the operation intensity of the heat exchange module, reducing energy consumption as the target temperature approaches. Simultaneously, the scene adaptation module modifies the control strategy based on indoor space characteristics, occupant activity, and outdoor environmental conditions to avoid unnecessary energy consumption. The refrigerant management unit also reduces the refrigerant circulation volume as the target temperature approaches, improving refrigerant utilization efficiency. Furthermore, the self-learning function of the decision control unit continuously optimizes the control logic, allowing the system to continuously improve its energy-saving level over long-term use, achieving a perfect balance between high-efficiency cooling and low energy consumption.

The refrigeration cycle unit 11 is used to realize the circulation of low GWP refrigerant to complete the refrigeration process. The refrigerant management unit 12 is used to control the flow rate and status of low GWP refrigerant. Refrigerant with a GWP value of less than 150 circulates within the core refrigeration module 1.

[0033] The enhanced heat exchange module 2 is connected to the heat exchange end of the core refrigeration module 1 and is used to enhance the heat exchange efficiency between the refrigeration cycle unit 11 and the indoor air in order to achieve rapid cooling. The enhanced heat exchange module 2 can adjust the heat exchange intensity according to the cooling demand.

[0034] The intelligent control center 3 establishes control connections with the core cooling module 1 and the enhanced heat exchange module 2 respectively. It can dynamically adjust the cooling output of the core cooling module 1 and the operating intensity of the enhanced heat exchange module 2 according to the difference between the indoor temperature and the target temperature, thereby improving the cooling and heat exchange efficiency during the rapid cooling phase and reducing energy consumption when approaching the target temperature.

[0035] It should be noted that in this embodiment, the core refrigeration module 1 uses a refrigerant with a GWP value below 150, reducing the negative environmental impact of the air conditioner from the source, which aligns with environmental protection trends. The enhanced heat exchange module 2 improves heat exchange efficiency, meets rapid cooling requirements, and enhances the user's immediate experience. The intelligent control center 3 dynamically adjusts based on temperature differences, achieving a balance between rapid cooling and low energy consumption. This ensures cooling speed while avoiding energy waste, allowing the system to reach an optimal state between high efficiency and energy saving.

The airflow drive module 22 is used to accelerate the speed of air flowing through the heat exchange end, and the operating parameters of the airflow drive module 22 can be adjusted by the intelligent control center 3.

[0037] In this embodiment, the enhanced heat exchange module 2 is the core component in the indoor unit of the air conditioner responsible for enhancing heat exchange, and includes a heat conduction enhancement unit 21 and an airflow drive module 22. The heat conduction enhancement unit 21 forms a highly efficient heat transfer connection with the evaporator heat exchange end of the core refrigeration module 1 through close contact, directly improving the basic heat transfer capability.

The synergistic effect of these two components significantly enhances the controllability of heat exchange intensity, ensuring efficient heat exchange at different cooling stages, providing stronger support for rapid cooling, and laying the foundation for subsequent energy consumption control.

[0038] Optional, please refer to the appendix Figure 1 The heat conduction enhancement unit 21 includes a heat transfer substrate 211 and a heat dissipation enhancement structure 212. The heat transfer substrate 211 is closely attached to the heat exchange end of the core cooling module 1 to conduct heat quickly.

[0039] In this embodiment, the structure of the heat conduction enhancement unit 21 is refined, specifically including a heat transfer substrate 211 and a heat dissipation enhancement structure 212. The heat transfer substrate 211 is a metal guide plate closely attached to the surface of the evaporator, typically made of copper or aluminum, which is tightly fitted to the heat exchange end of the evaporator of the core refrigeration module 1 to ensure the initial efficiency of heat conduction. The heat dissipation enhancement structure 212 is a fin assembly disposed on the metal guide plate. The fin assembly is comb-shaped or corrugated, which can increase the contact area with air and significantly improve the speed at which heat is dissipated into the air. This structural design improves the heat transfer efficiency from the two key aspects of conduction and dissipation, substantially enhancing the heat exchange capacity of the enhanced heat exchange module 2, accelerating the rate of indoor temperature reduction, and improving the rapid cooling effect.

[0041] In this embodiment, the airflow drive module 22 is the air supply system of the indoor unit of the air conditioner, including a power drive unit 221 and an airflow pushing structure 222. The power drive unit 221 is an adjustable speed motor, such as a brushless DC motor, electrically connected to the intelligent control center 3, receiving control commands to adjust the operating state; the airflow pushing structure 222 is a centrifugal fan or axial fan connected to the motor, which pushes airflow under the drive of the power drive unit 221 to accelerate heat exchange. When rapid cooling is required, the fan speed can be increased to accelerate heat exchange; when approaching the target temperature, the speed is reduced to reduce energy consumption. This precise controllability allows the airflow drive module 22 to better cooperate with the system to achieve energy-saving goals while ensuring heat exchange efficiency.

[0046] In this embodiment, the environmental perception module 31 collects various parameters in real time, providing accurate basis for decision-making; the adaptive adjustment algorithm of the decision control unit 32 can generate scientific control strategies; and the execution adjustment module 33 ensures the effective execution of the strategies. The three form a complete control closed loop, enabling the system to dynamically adjust the operation of each module according to the actual situation, efficiently cool down during the rapid cooling phase, and precisely control energy when approaching the target temperature, greatly improving the system's intelligence level and operational rationality.

For example, the cooling intensity can be appropriately reduced in unoccupied areas, and the indoor cooling target can be adjusted according to the outdoor temperature, making the system operation more in line with the actual use scenario, further improving the accuracy of energy consumption control and reducing unnecessary energy consumption.

[0049] Optional, please refer to the appendix Figure 1 The refrigerant management unit 12 of the core refrigeration module 1 is connected to the intelligent control center 3, which can increase the refrigerant circulation volume during the rapid cooling stage and reduce the circulation volume when approaching the target temperature, thereby improving the refrigerant utilization efficiency.

[0050] In this embodiment, the refrigerant management unit 12 of the core refrigeration module 1, typically an electronic expansion valve or a thermostatic expansion valve, is connected to the intelligent control center 3. It adjusts the refrigerant circulation volume according to refrigeration demand, increasing the circulation volume during the rapid cooling phase to ensure sufficient cooling capacity, and decreasing the circulation volume as the temperature approaches the target temperature to avoid increased energy consumption due to refrigerant excess. This dynamic adjustment improves refrigerant utilization efficiency, ensuring the most rational use of refrigerant at different stages, thus guaranteeing both cooling effect and reduced energy consumption.

This reduces the contact thermal resistance between the two, allowing heat to be conducted more smoothly from the evaporator to the heat transfer substrate 211, and reducing heat loss during the transfer process. This structure further improves the efficiency of heat conduction, making the overall heat exchange performance of the heat conduction enhancement unit 21 better, accelerating the heat transfer speed, and helping the system achieve rapid cooling.
