[0012] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0013] like Figure 1 As shown, a high-efficiency solar jet refrigeration device includes a solar column 1, a solar tracking gimbal steering system 2, a dish-shaped solar collector reflector 3, a solar collector generator 4, a working fluid condenser 6, a heat exchange evaporator 8, an energy storage and heat preservation water tank 10, an air curtain machine 12, a water inlet 15, and a solar water heater. The solar column 1 and the solar tracking gimbal steering system 2 are fixedly connected; the solar tracking gimbal steering system 2 and the dish-shaped solar collector reflector 3 are rotatably connected; the dish-shaped solar collector reflector 3 and the solar collector generator 4 are fixedly connected. The solar column 1 provides support and is equipped with a horizontal and vertical steering device that can rotate up, down, left, and right via a motor.

[0014] The solar collector 4 and the working fluid condenser 6 are connected by pipes. The solar collector 4 and the dual-axis solar tracker are connected by pipes. The working fluid circulation pump 5 is installed on the connecting pipe of the working fluid condenser 6. The working fluid condenser 6 and the heat exchange evaporator 8 are connected by pipes. An expansion injection valve 7 is installed on the connecting pipe of the working fluid condenser 6 and the heat exchange evaporator 8. The heat exchange evaporator 8 and the energy storage and heat preservation water tank 10 are connected by pipes. The heat exchange circulation pump 9 is installed on the connecting pipe of the heat exchange evaporator 8 and the energy storage and heat preservation water tank 10. The energy storage and heat preservation water tank 10 and the air curtain machine 12 are connected by pipes. The upper connecting pipe between the energy storage and heat preservation water tank 10 and the air curtain machine 12 is a condensate pipe 13, and a condensate pressurization pump 11 is installed on the condensate pipe 13. The lower connecting pipe between the energy storage and heat preservation water tank 10 and the air curtain machine 12 is a return water pipe 14. The energy storage and heat preservation water tank 10 and the water inlet 15 are fixedly connected.

[0015] Preferably, the dual-axis solar tracker further includes a motor or actuator, sensors, a dish-shaped solar receiver, and a collector; the solar tracking controller calculates and controls the movement of the device based on a preset algorithm and sensor data; the motor or actuator receives controller commands and adjusts the device angle; the sensors are photoelectric sensors and tilt sensors, providing real-time feedback on the sun's position; the dish-shaped solar receiver focuses sunlight into heat energy to heat the heat transfer oil or refrigerant inside the collector; the collector also includes a spot tracking system to ensure that the collector can receive the focused spot of the dish-shaped solar receiver to the maximum extent, which is essentially to move the collector up and down to obtain the maximum value of the focal spot temperature.

[0016] Steering principle of dual-axis solar trackers: Dual-axis solar trackers significantly improve efficiency by precisely adjusting the angle of a disc-shaped focusing lens to always point towards the sun. Their operation relies primarily on two control methods: light control and time control. Light control utilizes light sensors to detect differences in light intensity across different areas, determining the sun's position and driving a motor to adjust the gimbal support. This method achieves high-precision tracking on clear days. Time control calculates the sun's position based on local latitude, longitude, and time using astronomical formulas, and then uses a motor to drive the gimbal for tracking. The GPS module provides accurate time and location information (the relationship between solar altitude angle and azimuth angle; solar altitude angle is the angle at which the sun is above the horizon. It changes daily throughout the year. At the winter solstice (December 22), the sun is at 23.5° north latitude. After that, the sun gradually moves north, until the spring equinox (March 21), when it is directly above the equator (latitude 0°). Then it continues to move north, until the summer solstice when it is directly above the Tropic of Cancer (23.5° north latitude). Then it turns around and moves south, until the autumn equinox when it returns to the equator at 0° latitude. At the winter solstice (December 22), it moves back to the Tropic of Capricorn, and so on, with the changing of the seasons).

[0017] When using: Using the refrigerant in the solar thermal collector 4, a high-temperature and high-pressure refrigerant is generated. The vapor is condensed into liquid through the refrigerant condenser 6 and enters the heat exchange evaporator 8 through the expansion jet valve 7 to complete the heat exchange. The low-pressure liquid returns to the heat exchange evaporator 8 and circulates again to achieve refrigeration and heat exchange. The condensate from the heat exchange evaporator 8 enters the energy storage water tank. The condensate is then supplied to the air curtain machine 12 by the condensate pressurization pump 11 and returned to the energy storage and heat preservation water tank 10 through the return water pipe 14.

[0018] In summary: This application makes full use of the high-efficiency dish-shaped solar tracking system 2, which allows the solar thermal generator 4 to quickly generate high-temperature and high-pressure steam, which together with the working fluid condenser 6, expansion jet valve 7, heat exchange evaporator 8, and air curtain machine 12 to form a complete refrigeration chain, creating a green, energy-saving and environmentally friendly product, and completing the process of transforming scientific and technological achievements.

[0019] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0020] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
