Description

Technical Field

[0001] This utility model relates to the technical field of fruit and vegetable preservation equipment, specifically a highly integrated controlled atmosphere type fruit and vegetable storage air cooler. Background Technology

[0002] An evaporative air cooler is a device that uses the principle of evaporative cooling to cool the air. It is also often called an evaporative air cooler or an environmentally friendly air conditioner. Its core features are energy saving and ventilation. It is fundamentally different from the refrigeration principle of traditional compressor air conditioners. Fruit and vegetable cold storage air coolers are low-temperature cooling devices specifically used in cold storage for fruit and vegetable preservation. They are the core terminal devices of a compression refrigeration system. Their function is to absorb heat through the phase change of the refrigerant, providing a stable low temperature for the storage environment of fruits and vegetables. Combined with humidity control and ventilation functions, it slows down the respiration and spoilage of fruits and vegetables, and extends their shelf life.

[0003] In the field of fruit and vegetable preservation, in order to extend the shelf life of fruits and vegetables, it is necessary to control the temperature and humidity in cold storage and remove ripening gases such as ethylene. In traditional fruit and vegetable storage equipment, ethylene purification devices, ultrasonic humidifiers, and air coolers are usually set up independently, which requires a large area and has high installation and maintenance costs.

[0004] Existing standalone air coolers cannot accurately control humidity and remove ethylene simultaneously while refrigerating. Furthermore, standalone ethylene purification devices and ultrasonic humidifiers are difficult to match with the working rhythm of air coolers, failing to achieve efficient integrated preservation functions. At the same time, the combination of standalone equipment results in high energy consumption for the entire system, which is not conducive to energy conservation and emission reduction.

In order to extend the shelf life of fruits and vegetables, multiple components inside the device housing 1 are controlled by the control box 3, which effectively improves the practicality of the equipment.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 An electric air valve 11 is provided on the outer wall of the device housing 1, and the purification module 10 and the electric air valve 11 are arranged opposite to each other. The electric air valve 11 can effectively adjust the working air volume of the ethylene purification module 10 and improve the working efficiency of the equipment.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The device housing 1 has a drain outlet 8 at the bottom center point and a water inlet 12 on the side wall. When the ultrasonic humidifier 6 module is working, the electric valve of the drain outlet 8 is closed and the electric valve of the water inlet 12 is opened. The water volume is determined by the float level sensor, and the ultrasonic humidifier 6 module is controlled to work. The air outlet of the ultrasonic humidifier 6 module is connected to the cold storage, and the air after cooling, ethylene purification and humidification is sent into the cold storage.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The humidifier 6 includes a water tank, an ultrasonic transducer, and a water supply and drainage control unit, which atomizes the water in the water tank into tiny water droplets and mixes them into the passing airflow, thereby regulating the air humidity.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The inner wall of the device housing 1 is also equipped with multiple sets of sensors, including ethylene concentration sensors, temperature and humidity sensors, evaporation temperature sensors, and float level sensors. The setting of multiple sets of sensors (which belongs to the prior art) facilitates the automated operation of the equipment according to the warehouse conditions and improves the practicality of the equipment.

The electric valves control the drain outlet 8 and the water inlet 12. In addition, the electric valves are connected to the sensors to effectively control the operation of the humidifier 6.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 An expansion valve 4 and a distributor 5 are placed between the purification module 10 and the humidifier 6. The control box 3, the purification module 10, the expansion valve 4, and the humidifier 6 are located on the same horizontal line.

[0045] Second embodiment:

[0046] Please see Figure 1 , Figure 2 The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, a movable cover plate is provided at the top of one end of the device housing 1 to facilitate the maintenance of the components inside the device.

[0047] The movable cover allows workers to regularly replace the catalyst in the ethylene purification module 10 to ensure its purification effect on ethylene, regularly clean the water tank of the ultrasonic humidifier 6 to prevent scale and bacteria growth, check the working status of the ultrasonic transducer, regularly check for leaks or other faults in the refrigeration coil, and replenish the refrigerant in a timely manner.

[0048] In practical operation, this utility model is as follows:

[0049] When the equipment is started, the axial flow fan 2 starts to operate, drawing air from the storage room into the equipment. The air first passes through the high-temperature cold air module, where the refrigerant in the cooling coil absorbs heat from the air, lowering the air temperature. After further enhanced heat dissipation by the heat dissipation fins, the low-temperature air enters the ethylene purification module 10. In the ethylene purification module 10, based on the signal fed back by the ethylene concentration sensor in the storage room, the control system adjusts the opening of the electric air valve 11. If the ethylene concentration is high, the opening of the electric air valve 11 increases, allowing more low-temperature air to enter the ethylene purification module 10. Under the action of the catalyst, ethylene is catalytically oxidized into carbon dioxide and water, thereby reducing the ethylene content in the air.

[0050] After being purified by ethylene, the air enters the ultrasonic humidifier module 6. The ultrasonic transducer atomizes the water in the water tank into tiny water droplets, which are then mixed into the air, increasing the air humidity to a suitable range for fruit and vegetable preservation. Finally, the air, after being cooled, purified by ethylene, and humidified, is sent into the fruit and vegetable storage room through the equipment's air outlet, achieving integrated control of the environment inside the fruit and vegetable storage room.

[0051] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
