The high-temperature low-pressure gas of the No. 2 internal heat exchanger 62 is sequentially transported to the compressor 32 by the No. 4 branch pipe 741, the No. 1 three-way branch pipe 714, the four-way valve 71 and the No. 2 branch pipe 712. The compressor 32 re-compresses the high-temperature low-pressure gas into high-temperature high-pressure gas, and so on, thereby achieving the effect of driving the No. 1 and No. 2 internal heat exchangers for refrigeration and dehumidification by only one external heat exchanger;

[0056] Specifically, Figure 7 As shown, when only heating / cooling is used, three-way valve No. 1 72 opens the left and right connection ends, three-way valve No. 3 74 opens the upper and lower connection ends, three-way valve No. 4 75 opens the left and right connection ends, three-way valve No. 5 76 opens the left and lower connection ends, and three-way valve No. 6 77 opens the upper and left connection ends, thereby achieving the effect of heating / cooling only.

[0057] Based on the above, through the No. 1 fan 41 and the carefully designed air supply duct system, efficient air internal circulation can be achieved to ensure uniform distribution and rapid circulation of air in the core area. The two No. 1 internal heat exchangers 51 are symmetrically arranged in the box 42, which can cover the two output ends of the box 42, thereby achieving more accurate temperature control;

[0058] In addition, the integration with the external heat exchange unit 3 (including the external heat exchanger 31, the compressor 32 and the expansion valve 33) enables the system to adjust the indoor temperature according to actual needs. By setting the humidifier 61 and the two No. 2 internal heat exchangers 62 at the branch point of the three-way air supply duct 44, the system can effectively adjust the indoor humidity to meet the needs of different environments;

[0059] At the same time, through the precise control of the electrically controlled valves (such as the four-way valve 71 and the three-way valves 72-77 No. 1-6), the energy flow path is optimized and unnecessary energy loss is reduced.

[0060] In addition, the electrical connection with the energy storage unit 113 enables the system to store energy when the energy is sufficient and release it when needed, thereby achieving energy saving and environmental protection effects;

[0061] All major components (such as fans, air valves, humidifiers, compressors, expansion valves, etc.) are connected to the central control unit 112 by signal, realizing automatic control and intelligent management of the system. This can not only simplify the operation, but also improve the operating efficiency and reliability of the system.

[0062] Further, such as Figure 2 and 3 As shown, it also includes a fresh air unit 9, which includes a No. 2 fan 91, an air delivery pipe 92 and a No. 2 air valve 93. A No. 2 mounting hole for mounting the No. 2 fan 91 is provided on the inner wall of the climate chamber body above the ceiling 121. Both ends of the air delivery pipe 92 are connected to the output end of the No. 2 fan 91 and the input end of the No. 2 air valve 93. The box body 42 has two input ends, which are symmetrically arranged up and down. The output end of the No. 2 air valve 93 is connected to the input end on the upper side of the box body 42.

[0063] Specifically, when external air needs to be supplemented, fan No. 1 41 and air valve No. 1 43 are both closed, fan No. 2 91 and air valve No. 2 93 are both opened, fan No. 2 91 inhales external air and delivers it to the box body 42 through the air supply pipe 92 and air valve No. 2 93 in turn, and then delivers it to the layout area 123 through the three-way air supply pipe 44 and the air supply channel in turn.

[0064] Further, such as Figure 2 and 3 As shown, in order to reduce the power of the compressor and the expansion valve when cooling / heating and dehumidifying, the volume of the No. 2 internal heat exchanger 62 is smaller than that of the No. 1 internal heat exchanger 51, and the No. 2 internal heat exchanger 62 is hingedly provided with an air guide plate 621 at the bottom end near the No. 1 internal heat exchanger 51 on the same side, and the top of the inner wall of the box body 42 on both sides of the No. 2 internal heat exchanger 62 is symmetrically and hingedly provided with two telescopic rods 622, the telescopic rods 622 are connected to the central control unit 112 by signal, and the telescopic rods 622 are electrically connected to the energy storage unit 113, and the execution ends of the two telescopic rods 622 are respectively hinged to the middle of the outer walls of the two sides of the air guide plate 621 on the same side, and the width of the air guide plate 621 is greater than the width of the second internal heat exchanger 62, and the opposite sides of the two air guide plates 621 are in contact with each other;

[0065] The structures of the No. 1 air valve 43 and the No. 2 air valve 93 are the same. The inner wall of the No. 1 air valve 43 is a regular quadrilateral. The length of the air guide plate 621 is equal to the length of the inner wall of the No. 1 air valve 43. The side wall of the air guide plate 621 can slide with the inner wall of the No. 1 air valve 43.

[0066] Specifically, during heating and dehumidification, the central control unit 113 controls the telescopic rod 622 to extend, and drives the air guide plate 621 to rotate downward 45° with the hinge of the air guide plate 621 and the No. 2 internal heat exchanger 62 as the center of the circle. The two air guide plates 621 form a channel on the opposite side. The original air flow delivered to the box body by either the No. 1 fan 41 or the No. 2 fan 93 is guided by the air guide plate 621, thereby generating a diversion. When the air flow at the top of the air guide plate 621 passes through the No. 2 internal heat exchanger 62, it is converted into a cold air flow due to heat exchange, and the original air flow at the lower end of the air guide plate 621 is maintained. The original temperature, the original airflow and the cold airflow will be mixed and heat exchanged when passing through the No. 1 internal heat exchanger 51 and the No. 2 internal heat exchanger 62 at the same time, and a new airflow will be formed. The temperature of the new airflow is greater than the cold air flow. The new airflow can be heat exchanged when passing through the No. 1 internal heat exchanger 51. Since the temperature of the new airflow is greater than the temperature of the cold air flow, the problem of polarization of the upper and lower heat exchange rates of the No. 1 internal heat exchanger 51 is avoided, so that the No. 1 internal heat exchanger 51 can perform uniform heat exchange, thereby reducing the power of the compressor 31 and the expansion valve 33 when in use;

[0067] When the refrigeration and dehumidification are performed and the fresh air unit 9 is closed, the hinge of the air guide plate 621 and the No. 2 internal heat exchanger 62 is the center of the circle, and the air guide plate 621 rotates downward 90 degrees, and the side wall is in contact with the inner wall of the No. 1 air valve 43, and a channel is formed between the two air guide plates 621. After the original air flow enters the box body 42, the channel guides most of the original air flow to the No. 2 internal heat exchanger 62, and the original air flow exchanges heat with the No. 2 internal heat exchanger 62 and turns into cold air flow, and then exchanges heat with the No. 1 internal heat exchanger 51, so as to perform secondary refrigeration, thereby reducing the power of the compressor 31 and the expansion valve 33 when in use;

[0068] When cooling and dehumidification is performed and the No. 1 air valve 43 is closed, the two air guide plates 621 are kept closed on the opposite side, and the two air guide plates 621 block the original air flow, and guide most of the original air flow to the No. 2 internal heat exchanger 62. The original air flow exchanges heat with the No. 2 internal heat exchanger 62 and is converted into cold air flow, and then heat is exchanged with the No. 1 internal heat exchanger 51, so as to perform secondary cooling, thereby reducing the power of the compressor 31 and the expansion valve 33 when in use;

[0069] Based on the above, through the telescopic effect of the telescopic rod 622, the air guide plate 621 can be accurately adjusted in angle relative to the No. 2 internal heat exchanger 62. This enables the system to accurately control the direction of air flow as needed, thereby improving the efficiency and accuracy of air conditioning;

[0070] At the same time, through the telescopic effect of the telescopic rod 622, the wind deflector 621 can be accurately adjusted in angle relative to the No. 2 internal heat exchanger 62. This enables the system to accurately control the direction of air flow as needed, thereby improving the efficiency and accuracy of air conditioning. The telescopic rod 622 is connected to the central control unit 112 by signal, so that the angle of the wind deflector can be dynamically adjusted according to actual needs. This flexibility enables the system to adapt to different environmental conditions and user needs, thereby achieving energy saving by accurately controlling the wind direction and enhancing the heat exchange effect;

[0071] At the same time, the hinged design between the air guide plate 621 and the telescopic rod 622 makes the assembly easy to disassemble and maintain. This helps to extend the service life of the system and reduce maintenance costs. The No. 1 air valve 43 and the No. 2 air valve 93 have the same structure, and the length of the air guide plate 621 is equal to the length of the inner wall of the No. 1 air valve 43. This design simplifies the structure of the assembly and reduces the complexity of manufacturing and installation.

[0072] Further, such as Figure 4As shown, the structures of the No. 1 internal heat exchanger 51 and the No. 2 internal heat exchanger 62 are the same. The No. 2 internal heat exchanger 62 includes a shell 621 and a fin heat exchanger 622 embedded and spot-welded into the shell 621. The shell 621 is made by welding four U-shaped steels. The four sides (upper, lower, left, and right) of the fin heat exchanger 622 are not in contact with the inner wall of the shell 621, and the output end and the input end both penetrate the outer wall of the shell 621 on the same side.

[0073] The water supply unit 2 includes a water storage tank 21, and an upper liquid level sensor 211 and a lower liquid level sensor 212 are arranged in the water storage tank 21;

[0074] The No. 2 pipe network 8 includes a water delivery pump 81, a control valve 83 and three-way valves 84 and 85, the control valve 83 and the three-way valves 84 and 85 are all electrically controlled valves.

A drainage branch pipe 852 is connected, and an external water supply pipe 86 is provided on the main pipe of the five-way branch pipe 851 from the housing 621 to the water storage tank 21. The control valve 83 is provided on the external water supply pipe 86. The water delivery pump 81, the control valve 83 and the No. 7-8 three-way valves 84-85 are all electrically controlled valves. The upper liquid level sensor 211, the lower liquid level sensor 212 and the control valve 83 are provided on the external water supply pipe 86. The water delivery pump 81, the control valve 83 and the No. 7-8 three-way valves 84-85 are all connected to the central control unit 112 by signal. The upper liquid level sensor 211, the lower liquid level sensor 212 and the control valve 83 are provided on the external water supply pipe 86. The water delivery pump 81, the control valve 83 and the No. 7-8 three-way valves 84-85 are all electrically connected to the energy storage unit 113.

[0075] Specifically, the external water source is sequentially delivered to the water storage tank 21 through the external water supply pipe 8 and the five-way branch pipe 851 main pipe. When the upper liquid level sensor 211 is triggered, the central control unit 112 controls the control valve 83 to close. When the plant growth environment needs to be humidified, the water delivery pump 81 is started, and the left and right connection ends of the No. 7 three-way valve 84 are opened. The water delivery pump 81 is started to deliver the water of the water storage tank 21 to the dehumidifier through the No. 5 three-way branch pipe 811. When the cleaning table 111 needs to be used, the left and lower connection ends of the No. 7 three-way valve 84 are opened, and the water delivery pump 81 is started to deliver the water of the water storage tank 21 to the cleaning table 111 through the No. 5 three-way branch pipe 811 main pipe and the No. 7 branch pipe 841.

[0076] When the lower liquid level sensor 212 is triggered, the central control unit 112 controls the control valve 83 to open;

[0077] When the No. 1 internal heat exchanger 51 and the No. 2 internal heat exchanger 62 are cooling and dehumidifying and the control valve 83 is closed, the upper and lower connection ends of the No. 8 three-way valve 85 are opened, and the moisture in the air condenses in the fin heat exchanger 622 to form water droplets, which fall into the shell 621 and are transported to the water storage tank 21 by the five-way branch pipe 851;

[0078] When the lower liquid level sensor 212 is triggered, the left and lower connection ends of the No. 8 three-way valve 85 are opened, and the water produced by the No. 1 internal heat exchanger 51 and the No. 2 internal heat exchanger 62 is discharged in turn through the five-way branch pipe 851 and the drainage branch pipe 85, and the output end of the drainage branch pipe 8 is arranged outside the climate chamber body 1;

[0079] Based on the above content, by setting a shell 621 for collecting water droplets on the fin radiator 622, and cooperating with the five-way branch pipe 851 to transport the water on the fin heat exchanger 622 collected by the shell 621 to the water storage tank 21, the effect of saving water is achieved. At the same time, multiple valves in the No. 2 pipe network 8 (such as the control valve 83 and the No. 7-8 three-way valves 84, 85) and the water pump 81 are all electrically controlled, and then cooperate with the upper and lower liquid level sensors 211, 212 to monitor the water level in the water storage tank 21 in real time and feedback to the automatic operation of the central control unit 112, thereby improving the automation degree and response speed of the system.

[0080] Furthermore, as shown in the figure, in order to increase the safety of water use, a filter 87 is provided on the main pipe of the five-way branch pipe 851 between the output end of the external water supply pipe 86 and the input end of the water storage tank 21, and the filter 87 is provided on the outer wall of the climate chamber body.
