Description

Technical Field

[0001] This utility model relates to the field of plant factory technology, and in particular to an integrated environmental control device for plant factories. Background Technology

[0002] In order to ensure the normal growth of plants, a large number of artificial light sources are set up in plant factories. This results in a large amount of heat inside the plant factory. In addition, due to the large amount of transpiration of plants, the water content inside the plant factory is also large. Therefore, plant factories not only need to be refrigerated all year round, but also need to remove a large amount of moisture from the indoor air in order to meet the conditions for plant growth.

[0003] In related technologies, dehumidifiers, air conditioning equipment, and fresh air equipment are generally used to work simultaneously to regulate humidity and temperature and provide ventilation in plant factories. However, the simultaneous operation of multiple devices greatly increases the cost of adjusting temperature and humidity inside plant factories, which is not conducive to cost reduction and efficiency improvement. Utility Model Content

[0004] The main purpose of this invention is to propose an integrated environmental control device for plant factories, which aims to reduce the cost of adjusting temperature and humidity inside plant factories.

[0005] To achieve the above objectives, the present invention proposes an integrated environmental control device for plant factories, comprising:

[0006] The body, wherein a flow channel is provided within the body;

[0007] A heat exchanger assembly is provided at the inlet of the flow channel, and a fan wall is provided on one side of the heat exchanger assembly.

[0008] A circulating flow channel group, which is connected to the heat exchanger group, to realize the refrigerant circulation inside the heat exchanger group;

[0009] An air duct is formed between the heat exchanger assembly and the fan wall, and the air duct extends to the outside of the unit body. A fresh air duct is provided on the unit body, which connects to the air duct and extends out of the unit body.

[0010] In one embodiment, the body is provided with a fresh air flow channel, the fresh air flow channel is connected to the air duct, and the fresh air flow channel extends out of the body;

[0011] The fresh air duct is equipped with a filter group.

[0012] In one embodiment, the heat exchanger assembly includes an evaporator section and a heat exchanger section, the evaporator section and the heat exchanger section being spaced apart within the flow channel, and the fan wall being disposed on the side of the heat exchanger section away from the evaporator section;

[0013] The evaporator section and the heat exchanger section are both connected to the circulation channel assembly so that the refrigerant in the circulation channel assembly circulates between the evaporator section and the heat exchanger section.

[0014] In one embodiment, the circulating channel assembly further includes a first liquid storage section and a second liquid storage section, the output end of the evaporator section is connected to the first liquid storage section through the circulating channel, and the output end of the heat exchanger section is connected to the second liquid storage section through the circulating channel;

[0015] One of the first liquid storage units has its output end connected to the input end of the compressor unit through the circulation channel, and the other of the second liquid storage units has its output end connected to the input end of the throttling unit through the circulation channel.

[0016] In one embodiment, the output end of the compressor section is provided with a three-way valve through the circulation channel, and one output end of the three-way valve is connected to the input end of the heat exchanger section through the circulation channel;

[0017] The other output end of the three-way valve is connected to an outdoor unit through the circulation channel, and the output end of the outdoor unit is connected to the input end of the second liquid storage unit through the circulation channel.

[0018] In one embodiment, both the output end of the heat exchanger section and the output end of the outdoor unit are equipped with a one-way valve.

[0021] In one embodiment, the evaporator section includes a plurality of evaporator units, which are arranged side by side at the inlet of the flow channel.

[0022] The technical solution of this utility model is to set up a heat exchanger group in the circulation channel. When the fan wall outputs power and draws out the gas in the plant factory, the gas passes through the heat exchanger group. Through the temperature difference of the heat exchanger group, the liquid inside the gas is liquefied and dehumidified. In the process of refrigerant circulation, the dehumidified and cooled gas can be reheated and sent back to the plant factory, thereby achieving dehumidification and temperature control of the plant factory environment. When the fan wall is working, a negative pressure can be formed in the air duct, so that the external fresh air can enter the circulation channel through the air duct, thereby achieving fresh air injection.

[0032] In order to ensure the normal growth of plants, a large number of artificial light sources are set up in plant factories. This results in a large amount of heat inside the plant factory. In addition, due to the large amount of transpiration of plants, the water content inside the plant factory is also large. Therefore, plant factories not only need to be refrigerated all year round, but also need to remove a large amount of moisture from the indoor air in order to meet the conditions for plant growth.

[0033] In related technologies, dehumidifiers, air conditioning equipment, and fresh air equipment are generally used to work simultaneously to regulate humidity and temperature and provide ventilation in plant factories. However, the simultaneous operation of multiple devices greatly increases the cost of adjusting temperature and humidity inside plant factories, which is not conducive to cost reduction and efficiency improvement.

[0034] Please see Figure 1 In one embodiment of this utility model, the plant factory integrates environmental control equipment, including:

[0035] The body 10 has a flow channel 11 inside it;

[0036] A heat exchanger assembly is provided at the inlet of the flow channel 11, and a fan wall 40 is provided on one side of the heat exchanger assembly.

[0037] A circulation channel group 60 is connected to the heat exchanger group to realize the refrigerant circulation inside the heat exchanger group.

[0038] A duct 70 is formed between the heat exchanger assembly and the fan wall 40, and the duct 70 extends to the outside of the body 10. A fresh air flow duct 80 is provided on the body 10, which connects to the duct 70 and extends out of the body 10.

[0039] In one embodiment, the heat exchanger assembly includes an evaporator section 20 and a heat exchanger section, the evaporator section 20 and the heat exchanger section being spaced apart within the flow channel 11, and the fan wall 40 being disposed on the side of the heat exchanger section away from the evaporator section 20.

[0040] The evaporator section 20 and the heat exchanger section are both connected to the circulation channel group 60 so that the refrigerant in the circulation channel group 60 circulates between the evaporator section 20 and the heat exchanger section.

[0041] It is understood that the circulation channel 11 is provided inside the body 10 for gas circulation. The circulation channel 11 is used for gas circulation. Moreover, the evaporator section 20 and the heat exchanger section are provided inside the circulation channel 11 so that the gas can be dehumidified by the evaporator section 20 and heated and regulated by the heat exchanger section during the gas flow in the circulation channel 11, so as to avoid the gas output temperature of the body 10 being too low and affecting plant growth.

[0042] It should be noted that the evaporator section 20 can be a plate evaporator. By increasing the surface area of ​​the evaporator section 20, when gas passes through the surface of the evaporator, the increased surface area increases the basic area between the gas and the evaporator, which facilitates the rapid liquefaction of water vapor carried in the gas and thus improves the dehumidification efficiency of the gas.

[0043] It is understandable that after the gas passes through the evaporator section 20 for dehumidification, the gas temperature decreases. If the cooled gas is directly sent into the room, it may easily affect the growth of plants in the plant factory.

[0044] Therefore, a heat exchanger section is provided on one side of the evaporator section 20 in the gas flow direction. In this way, when the dehumidified and cooled gas passes through the heat exchanger section, it is reheated so that the gas temperature can be raised to meet the growth requirements of plants in the plant factory and ensure the normal growth of plants.

[0045] Furthermore, in order to reuse the heat dissipated during the dehumidification process of the plant factory, the refrigerant in the evaporator section 20 is circulated to the heat exchanger section through the circulation channel assembly 60, so as to realize the secondary heating of the gas, that is, to realize the secondary utilization of waste heat, improve energy utilization and reduce costs.

[0046] In one embodiment, the body 10 is provided with a fresh air flow channel 80, the fresh air flow channel 80 is connected to the air duct 70, and the fresh air flow channel 80 extends out of the body 10;

[0047] A filter assembly is installed inside the fresh air duct 80.

[0048] It should be noted that, since plant factories are enclosed, regular ventilation is required inside.

[0049] It is understood that an air duct 70 is provided between the heat exchanger section and the fan wall 40 so that external gas can directly enter the plant factory along the fresh air flow duct 80, the air duct 70 and the circulation channel 11 during the operation of the fan wall 40.

[0050] It should be noted that the air duct 70 is formed between the heat exchanger section and the fan wall 40. During the operation of the fan wall 40, a negative pressure is formed in the air duct 70 so that the external atmospheric pressure can force the gas into the air duct 70 through the fresh air flow channel 80. This avoids the need to install a fresh air unit in the body 10, reduces the cost of the body 10, and meets the fresh air exchange requirements.

[0051] Understandably, when fresh air enters the plant factory, it does not pass through the evaporator and heat exchanger sections, thereby reducing energy consumption.

[0052] It is understandable that when the outdoor temperature and humidity environment is better than the indoor temperature and humidity environment of the plant factory, the fan wall 40 will work and the compressor unit 64 will not need to be turned on. At this time, a negative pressure channel is formed at the air duct 70, so that the outside air can enter the plant factory through the fresh air flow channel 80 and the air duct 70, thereby reducing the energy consumption for temperature and humidity control.

[0053] It is understandable that a filter module is installed in the fresh air duct 80 to filter the fresh air during the air intake process, thereby improving the gas quality in the plant factory.

[0054] The technical solution of this utility model is to install the heat exchanger group in the circulation channel 11. When the fan wall 40 outputs power and extracts the gas in the plant factory, the gas passes through the heat exchanger group. Through the temperature difference of the heat exchanger group, the liquid inside the gas is liquefied and dehumidified. In the process of refrigerant circulation, the dehumidified and cooled gas can be reheated and sent back to the plant factory, thereby achieving dehumidification and temperature control of the plant factory environment. When the fan wall 40 is working, a negative pressure can be formed in the air duct 70, so that external fresh air can enter the circulation channel 11 through the air duct 70, thereby achieving fresh air injection. By integrating the dehumidifier, air conditioning equipment and fresh air unit into an integrated design, the cost of temperature and humidity adjustment in the plant factory is greatly reduced.

[0055] In one embodiment, the circulating flow channel assembly 60 includes a circulating flow channel and a compressor section 64, wherein the compressor section 64 is connected between the output end of the evaporator section 20 and the input end of the heat exchanger section through the circulating flow channel.

[0056] It should be noted that when the refrigerant moves within the circulating flow channel assembly 60, a compressor unit 64 is provided to quickly heat the refrigerant to the required temperature and facilitate gas reheating. The compressor unit 64 heats and pressurizes the refrigerant, thereby preventing overcooled gas from being discharged into the plant factory and affecting the growth of plants within the plant factory.

[0057] It is understood that the circulating flow channel group 60 is used to connect the evaporator section 20 and the heat exchanger section. The output end of the evaporator section 20 is connected to the input end of the heat exchanger section through the circulating flow channel, and the input end of the evaporator section 20 is connected to the output end of the heat exchanger section through the circulating flow channel.

[0058] It is understood that the circulating flow channel group 60 realizes the circulation and replacement of refrigerant in the evaporator section 20 and the heat exchanger section, thereby circulating the heat in the evaporator section 20 and the heat exchanger section to improve the efficiency of heat utilization.

[0059] In order to achieve temperature regulation of the heat exchanger section, the compressor section 64 is added into the circulation channel group 60. When the compressor section 64 is working, it heats and pressurizes the low-temperature refrigerant flowing out of the evaporator section 20, so that the temperature of the refrigerant entering the heat exchanger section can be regulated, thereby achieving temperature regulation of the gas in the circulation channel 11 and improving the heat utilization efficiency.

[0060] In one embodiment, the circulating flow channel assembly 60 includes a throttling section 62, which is connected between the input end of the evaporator section 20 and the output end of the heat exchanger section through the circulating flow channel.

[0061] It is understood that the throttling section 62 is disposed between the evaporator section 20 and the heat exchanger section, and the throttling section 62 is connected to the input end of the evaporator section 20 and the output end of the heat exchanger section, respectively.

[0062] When the refrigerant flowing in the heat exchanger section dissipates heat and is discharged, it passes through the throttling section 62, which further reduces the temperature and pressure of the refrigerant, thereby making the refrigerant entering the evaporator section 20 meet the dehumidification requirements of the gas in the evaporator section 20.

[0063] It should be noted that the throttling section 62 is a throttling device.

[0064] Preferably, the throttling section 62 is a throttling valve.

[0065] In one embodiment, the circulating channel assembly 60 further includes a first liquid storage section 61 and a second liquid storage section 63. The output end of the evaporator section 20 is connected to the first liquid storage section 61 through the circulating channel, and the output end of the heat exchanger section is connected to the second liquid storage section 63 through the circulating channel.

[0066] One of the first liquid storage units 61 has its output end connected to the input end of the compressor unit 64 through the circulation channel, and the other of the second liquid storage units 63 has its output end connected to the input end of the throttling unit 62 through the circulation channel.

[0067] It should be noted that when the refrigerant circulating in the circulation channel group undergoes temperature changes, the refrigerant will switch between gas and liquid states. This can easily lead to pressure changes in the circulation channel, affecting the stability of the refrigerant's flow within the circulation channel.

[0068] Therefore, a first liquid storage section 61 and a second liquid storage section 63 are respectively provided at the output end of the evaporator section 20 and the output end of the heat exchanger section, so that the refrigerant in the evaporator section 20 and the heat exchanger section flows into the first liquid storage section 61 and the second liquid storage section 63 after the temperature changes, so as to achieve gas-liquid separation and ensure the stability of the refrigerant flow in the circulation channel.

[0069] In one embodiment, the output end of the compressor section 64 is provided with a three-way valve 66 through the circulation channel, and one output end of the three-way valve 66 is connected to the input end of the heat exchanger section through the circulation channel;

[0070] The other output end of the three-way valve 66 is connected to the outdoor unit 65 through the circulation channel, and the output end of the outdoor unit 65 is connected to the input end of the second liquid storage section 63 through the circulation channel.

[0071] When the temperature inside the plant factory is too high and cooling is required, the gas passes through the evaporator section 20 and exchanges heat with it, causing the gas temperature to drop. At this time, the compressor section 64 stops working. As the refrigerant returns to the heat exchanger section, the gas temperature will not rise too high when passing through the heat exchanger section, thus affecting the cooling of the plant factory.

[0072] like Figure 1 As shown, in order to facilitate the release of excess heat, the circulation channel 11 is provided on both sides of the circulation channel 11, and the output end of the compressor section 64 in one of the circulation channel groups 60 is connected to the three-way valve 66.

[0073] It should be noted that if the refrigerant temperature is too high, and all the refrigerant enters the heat exchanger section, the gas temperature will rise too high. In this case, the refrigerant needs to be diverted.

[0074] It is understood that the three-way valve 66 is provided at the output end of the compressor section 64 so that the refrigerant output by the compressor section 64 can be transmitted to the heat exchanger section in one direction and to the outdoor unit 65 in another direction.

[0075] It is understandable that when the refrigerant is transferred to the outdoor unit 65 through the three-way valve 66, the outdoor unit 65 operates to dissipate heat from the refrigerant flowing through it, thereby preventing the refrigerant returning to the second liquid storage section 63 from overheating and affecting the dehumidification quality and efficiency of the evaporator section 20 after it is output from the output end of the second liquid storage section 63 to the evaporator section 20.

[0076] It is understandable that the Soul Ring Flow Channel Group 60 on both sides of the flow channel 11 operates in coordination to improve energy utilization and assist in temperature regulation and dehumidification within the plant factory.

[0077] In one embodiment, a one-way valve 67 is provided at the output end of the heat exchanger section and at the output end of the outdoor unit 65.

[0078] To prevent refrigerant from flowing back into the heat exchanger section through the output end of the heat exchanger section when the outdoor unit 65 transfers refrigerant to the second liquid storage section 63, or to prevent refrigerant from flowing out of the heat exchanger section and transferring to the second liquid storage section 63 and then flowing back into the outdoor unit 65 through the output end of the outdoor unit 65, a one-way valve 67 is provided at both the output end of the heat exchanger section and the output end of the outdoor unit 65.

[0079] It is understandable that the refrigerant flow direction from the outdoor unit 65 to the second liquid storage section 63 and the flow direction from the heat exchanger section to the second liquid storage section 63 are prevented from backflowing due to the presence of the one-way valve 67, thereby ensuring the stability of the refrigerant transmission.

[0080] In one embodiment, the heat exchanger section includes a heat recovery section 30 and a condensation section 50, which are arranged side by side in the flow channel 11;

[0081] A circulation channel group 60 is provided between the heat recovery section 30 and the evaporator section 20, and a circulation channel group 60 is provided between the condensation section 50 and the evaporator section 20.

[0082] When conventional dehumidification equipment in a plant factory is working, the heat generated by the equipment can affect the growth of plants around it.

[0083] Therefore, the heat exchanger section of this utility model, which is set in the circulation channel 11, includes the heat recovery section 30 and the condensation section 50, for recovering the heat generated by the operation of the compressor section 64 and the heat absorbed from the plant factory through the evaporator section 20, thereby further achieving the purpose of waste heat recovery and improving energy utilization efficiency.

[0084] It is understood that the heat exchanger section also includes a condenser section 50, which is disposed on the side of the evaporator section 20. This allows the gas that has been dehumidified and cooled by the evaporator section 20 to be reheated by the condenser section 50, thereby preventing the dehumidified gas flowing through the flow channel 11 from affecting the normal growth of plants in the plant factory due to its low temperature.

[0085] It is understood that by connecting the condenser section 50 and the evaporator section 20 through the circulation channel assembly 60, the refrigerant flowing through the evaporator section 20 can flow back to the condenser section 50 under the guidance of the circulation channel. The heat carried by the refrigerant is then used to heat the gas again in the condenser section 50, thereby realizing the reuse of recovered heat and improving the efficiency of heat utilization.

[0086] In one embodiment, the evaporator section 20 includes a plurality of evaporator units, which are arranged side by side at the inlet of the flow channel 11.

[0087] like Figure 2As shown, multiple evaporator units are stacked side by side at the inlet of the flow channel 11, and the multiple evaporator units fill and block the inlet of the flow channel. This ensures that all the gas drawn into the flow channel 11 by the fan wall 40 can pass through the evaporator section 20 before flowing to the heat exchanger section, thereby ensuring the dehumidification effect of the gas.

[0088] It is understood that multiple evaporator units are arranged in a single row at the inlet of the flow channel, thereby facilitating the evaporator section 20 to block the flow channel.

[0089] It should be noted that the heat recovery section 30 and the condensation section 50 are arranged in a single row in the flow channel and are located on one side of the evaporator section 20, so that the heat exchanger section can be blocked in the flow channel, so that the dehumidified and cooled gas can be heated by the heat exchanger section.

[0090] Meanwhile, the fan wall 40 includes multiple fan units, which are arranged in a single row at the outlet of the circulation channel. When the multiple fan units are working, they draw gas from the inlet of the circulation channel to the outlet of the circulation channel to achieve dehumidification and temperature regulation of the gas.

[0091] It is understood that the evaporator section 20, the heat exchanger section, and the fan wall 40 are integrated into the flow channel to facilitate gas dehumidification and temperature regulation. Furthermore, the refrigerant is circulated between the evaporator section 20 and the heat exchanger section through the circulation channel, enabling the recycling of recovered heat. This reduces equipment size and cost while improving energy utilization.

[0092] In one embodiment, an air duct 70 is formed between the heat exchanger section and the fan wall 40, and a fresh air flow duct 80 is provided on the body 10, the fresh air flow duct 80 is connected to the air duct 70, and the fresh air flow duct 80 extends out of the body 10.

[0093] It should be noted that, since plant factories are enclosed, regular ventilation is required inside.

[0094] It is understood that an air duct 70 is provided between the heat exchanger section and the fan wall 40 so that external gas can directly enter the plant factory along the fresh air flow duct 80, the air duct 70 and the circulation channel 11 during the operation of the fan wall 40.

[0095] It should be noted that the air duct 70 is formed between the heat exchanger section and the fan wall 40. During the operation of the fan wall 40, a negative pressure is formed in the air duct 70 so that the external atmospheric pressure can force the gas into the air duct 70 through the fresh air flow channel 80. This avoids the need to install a fresh air unit in the body 10, reduces the cost of the body 10, and meets the fresh air exchange requirements.

[0096] Understandably, when fresh air enters the plant factory, it does not pass through the evaporator and heat exchanger sections, thereby reducing energy consumption.

[0097] It is understandable that when the outdoor temperature and humidity environment is better than the indoor temperature and humidity environment of the plant factory, the fan wall 40 will work and the compressor unit 64 will not need to be turned on. At this time, a negative pressure channel is formed at the air duct 70, so that the outside air can enter the plant factory through the fresh air flow channel 80 and the air duct 70, thereby reducing the energy consumption for temperature and humidity control.

[0098] In one embodiment, a filter assembly is provided within the fresh air duct 80.

[0099] It is understandable that a filter module is installed in the fresh air duct 80 to filter the fresh air during the air intake process, thereby improving the gas quality in the plant factory.

[0100] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
