[0001] The present invention relates to the technical field of plant factories, and in particular to integrated environmental control equipment for plant factories. Background Art

[0002] In order to ensure the normal growth of plants, a large number of artificial light sources are installed in plant factories, which leads to high heat inside the plant factories. In addition, due to the presence of a large number of plant transpiration, the water content inside the plant factories is also high. Therefore, the plant factories not only need year-round cooling, but also need to remove a large amount of moisture from the indoor air to meet the conditions for plant growth.

[0003] In the related technology, dehumidifiers, air conditioning equipment, fresh air equipment, etc. are generally used to work simultaneously to achieve the adjustment of humidity and temperature as well as ventilation in the plant factory. However, when multiple devices work simultaneously, the overall power is relatively large. In addition, since the air conditioning equipment can also achieve dehumidification during operation, the synchronous operation of the dehumidifier reduces the dehumidification efficiency, which increases the power of the entire environmental control equipment of the plant factory, increases energy consumption, and increases costs. Summary of the invention

[0004] The main purpose of the present invention is to propose an integrated environmental control device for a plant factory, aiming to achieve integrated temperature control and dehumidification to reduce equipment power, energy consumption, and cost.

[0005] To achieve the above-mentioned purpose, the plant factory integrated environmental control device proposed by the present invention comprises:

[0006] A body, wherein a circulation channel is provided in the body;

[0007] an evaporator portion, the evaporator portion being disposed at a channel inlet of the flow channel;

[0008] a heat exchanger part, wherein the heat exchanger part is arranged in the circulation channel, and a fan wall is arranged on a side of the heat exchanger part away from the evaporator part;

[0009] Wherein, a circulation channel group is arranged in the machine body, and the evaporator part and the heat exchanger part are both connected to the circulation channel group, so that the refrigerant in the circulation channel group circulates between the evaporator part and the heat exchanger part.

[0010] In one embodiment, the circulation flow channel group includes a circulation flow channel and a compressor part, and the compressor part is connected between the output end of the evaporator part and the input end of the heat exchanger part through the circulation flow channel.

[0011] In one embodiment, the circulation flow channel group includes a throttling portion, and the throttling portion is connected between the input end of the evaporator portion and the output end of the heat exchanger portion through the circulation flow channel.

The output end of the evaporator part is connected to the first liquid storage part through the circulating flow channel, and the output end of the heat exchanger part is connected to the second liquid storage part through the circulating flow channel;

[0013] Wherein, the output end of one of the first liquid storage parts is connected to the input end of the compressor part through the circulating flow channel, and the output end of the other second liquid storage part is connected to the input end of the throttling part through the circulating flow channel.

[0014] In one embodiment, a three-way valve is provided in the circulating flow channel at the output end of the compressor part, and one output end of the three-way valve is connected to the input end of the heat exchanger part through the circulating flow channel;

[0015] Wherein, the other output end of the three-way valve is connected to an external machine through the circulating flow channel, and the output end of the external machine is connected to the input end of the second liquid storage part through the circulating flow channel.

[0016] In one embodiment, check valves are provided at the output end of the heat exchanger part and the output end of the external machine.

[0021] In one embodiment, a filter group is provided in the fresh air flow channel.

[0022] The technical solution of the present invention is to arrange the evaporator part and the heat exchanger part at intervals in the circulation channel. When the fan wall outputs power and extracts the gas in the plant factory, the moisture in the gas is removed when the gas passes through the evaporator part. When the gas then passes through the heat exchanger part, the low-temperature gas is heated and raised in temperature, and is sent back into the plant factory, so as to realize the dehumidification and temperature control of the plant factory environment.

[0032] In a plant factory, in order to ensure the normal growth of plants, a large number of artificial light sources are set, which results in a large amount of heat in the plant factory. And due to the existence of a large number of plants, the water content in the plant factory is also large. Therefore, in the plant factory, it is necessary not only to cool all year round but also to remove a large amount of moisture in the indoor air to meet the conditions for plant growth.

[0033] In the related art, generally, a dehumidifier, air conditioning equipment, fresh air equipment, etc. work simultaneously to achieve the regulation of humidity, temperature and ventilation in the plant factory. However, when multiple devices work simultaneously, the overall power is large, and since the air conditioning equipment can also achieve dehumidification during operation, the synchronous operation of the dehumidifier reduces the dehumidification efficiency, resulting in an increase in the power of the entire environmental control equipment in the plant factory, an increase in energy consumption, and an increase in cost.

[0034] The present invention proposes an integrated environmental control device for a plant factory.

[0035] Please refer to Figure 1 , in an embodiment of the present invention, the integrated environmental control device for the plant factory includes:

[0036] The body 10 is provided with a circulation channel 11 therein;

[0037] The evaporator section 20 is arranged at the channel entrance of the circulation channel 11;

[0038] The heat exchanger section is arranged in the circulation channel 11, and a fan wall 40 is arranged on the side of the heat exchanger section facing away from the evaporator section 20;

[0039] Wherein, a circulation flow path group 60 is arranged in the body 10, and both the evaporator section 20 and the heat exchanger section are connected to the circulation flow path group 60, so that the refrigerant in the circulation flow path group 60 circulates between the evaporator section 20 and the heat exchanger section.

[0040] It can be understood that the circulation channel 11 is arranged in the body 10, and the circulation channel 11 is used for the circulation of gas. Moreover, due to the evaporator section 20 and the heat exchanger section arranged in the circulation channel 11, when the gas flows in the circulation channel 11, the gas can be dehumidified through the evaporator section 20, and the temperature of the gas can be raised and adjusted through the heat exchanger section, so as to avoid the output gas temperature of the body 10 being too low and affecting the growth of plants.

[0041] 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 the gas passes through the surface of the evaporator, due to the increased surface area, the contact area between the gas and the evaporator is increased, which facilitates the rapid liquefaction of the water vapor carried in the gas, and thus improves the dehumidification efficiency of the gas.

[0042] It can be understood that after the gas is dehumidified by the evaporator section 20, the temperature of the gas decreases. If the cooled gas is directly sent into the room, it is easy to affect the growth of plants in the plant factory.

[0043] Therefore, the heat exchanger section is arranged 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 heated again, so that the gas is heated up to meet the growth requirements of plants in the plant factory and ensure the normal growth of plants.

[0044] 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 flow path group 60, so as to realize the secondary heating of the gas, that is, the secondary utilization of waste heat, improve the energy utilization rate and reduce the cost.

[0045] The technical solution of the present invention is to arrange the evaporator part 20 and the heat exchanger part at intervals in the circulation channel 11. When the fan wall 40 outputs power and extracts the gas in the plant factory, when the gas passes through the evaporator part 20, the moisture in the gas is removed. When the gas then passes through the heat exchanger part, the low-temperature gas is heated and raised in temperature, and is sent back into the plant factory, so as to realize the dehumidification and temperature control of the plant factory environment. The evaporator part 20 and the heat exchanger part are connected through the circulation channel group 60, so as to transfer the heated refrigerant in the evaporator part 20 to the heat exchanger part, so as to realize the heating and temperature control of the gas flowing through the surface of the heat exchanger part. The refrigerant cooled in the heat exchanger part returns to the evaporator part 20 through the circulation channel group 60, so as to assist in the dehumidification of the gas flowing into the circulation channel 11. By reusing the heat during dehumidification, the energy utilization rate is improved, and the additional setting of electric heating equipment to increase the gas temperature is avoided, greatly improving the equipment operation efficiency and reducing the equipment cost.

[0046] In an embodiment, the circulation channel group 60 includes a circulation channel and a compressor part 64. The compressor part 64 is connected between the output end of the evaporator part 20 and the input end of the heat exchanger part through the circulation channel.

[0047] It should be noted that when the refrigerant moves in the circulation channel group 60, in order to quickly heat the refrigerant to the required temperature and facilitate the reheating of the gas, a compressor part 64 is provided. The compressor part 64 is used to heat and pressurize the refrigerant, so as to prevent the supercooled gas from being discharged into the plant factory and affecting the growth of plants in the plant factory.

[0048] It can be understood that the circulation channel group 60 is used to connect the evaporator part 20 and the heat exchanger part. The output end of the evaporator part 20 is connected to the input end of the heat exchanger part through the circulation channel, and the input end of the evaporator part 20 is connected to the output end of the heat exchanger part through the circulation channel.

[0049] It can be understood that the circulation channel group 60 realizes the cyclic replacement of the refrigerant in the evaporator part 20 and the heat exchanger part, so as to circulate the heat in the evaporator part 20 and the heat exchanger part, so as to improve the utilization efficiency of heat.

[0050] In order to realize the temperature control of the heat exchanger part, the compressor part 64 is added to the circulation channel group 60. When the compressor part 64 works, the low-temperature refrigerant flowing out of the evaporator part 20 is heated and pressurized, so that the temperature of the refrigerant entering the heat exchanger part can be regulated, and then the temperature increase regulation of the gas in the circulation channel 11 can be realized, and the utilization efficiency of heat is improved.

[0051] In one embodiment, the circulation channel group 60 includes a throttling portion 62, and the throttling portion 62 is connected between the input end of the evaporator portion 20 and the output end of the heat exchanger portion through the circulation channel.

[0052] It can be understood that the throttling portion 62 is disposed between the evaporator portion 20 and the heat exchanger portion, and the throttling portion 62 is respectively connected to the input end of the evaporator portion 20 and the output end of the heat exchanger portion.

[0053] When the refrigerant flowing in the heat exchanger portion dissipates heat and is discharged, it passes through the throttling portion 62 to further cool and depressurize the refrigerant, so that the refrigerant entering the evaporator portion 20 meets the dehumidification requirements of the gas in the evaporator portion 20.

[0054] It should be noted that the throttling portion 62 is a throttling device.

[0055] Preferably, the throttling portion 62 is a throttle valve.

[0056] In one embodiment, the circulation channel group 60 further includes a first liquid storage portion 61 and a second liquid storage portion 63. The output end of the evaporator portion 20 is connected to the first liquid storage portion 61 through the circulation channel, and the output end of the heat exchanger portion is connected to the second liquid storage portion 63 through the circulation channel;

[0057] Wherein, the output end of one of the first liquid storage portions 61 is connected to the input end of the compressor portion 64 through the circulation channel, and the output end of the other second liquid storage portion 63 is connected to the input end of the throttling portion 62 through the circulation channel.

[0058] It should be noted that when the refrigerant circulating in the circulation channel group undergoes a temperature change, the refrigerant will convert between gas and liquid states. Therefore, it is easy to cause pressure changes in the circulation channel and affect the stability of the refrigerant flowing in the circulation channel.

[0059] Therefore, the first liquid storage portion 61 and the second liquid storage portion 63 are respectively provided at the output end of the evaporator portion 20 and the output end of the heat exchanger portion. In this way, the refrigerant in the evaporator portion 20 and the heat exchanger portion flows into the first liquid storage portion 61 and the second liquid storage portion 63 after the temperature change, so as to facilitate gas-liquid separation and ensure the stability of the refrigerant flowing in the circulation channel.

[0060] In one embodiment, a three-way valve 66 is provided through the circulation channel at the output end of the compressor portion 64, and one output end of the three-way valve 66 is connected to the input end of the heat exchanger portion through the circulation channel;

[0061] Wherein, the other output end of the three-way valve 66 is connected to the external unit 65 through the circulation channel, and the output end of the external unit 65 is connected to the input end of the second liquid storage part 63 through the circulation channel.

[0062] When the temperature inside the plant factory is too high and cooling is required, the gas passes through the evaporator part 20 and exchanges heat with the evaporator part 20, and the temperature of the gas decreases. At this time, the compressor part 64 stops working. At this time, when the refrigerant returns to the inside of the heat exchanger part again, it will not cause the gas to heat up too much when passing through the heat exchanger part and affect the cooling inside the plant factory.

[0063] Such as Figure 1 As shown, in order to facilitate the release of excess heat, the circulation channel groups 60 are arranged on both sides of the circulation channel 11. The output end of the compressor part 64 in one of the circulation channel groups 60 is connected to the three-way valve 66.

[0064] It should be noted that when the temperature of the refrigerant is too high and the gas will heat up too much if all the refrigerant enters the heat exchanger part, the refrigerant needs to be shunted.

[0065] It can be understood that a three-way valve 66 is arranged at the output end of the compressor part 64, so that the refrigerant output by the compressor part 64 is transmitted to the inside of the heat exchanger part along one path and to the external unit 65 along another path.

[0066] It can be understood that when the refrigerant is transmitted to the inside of the external unit 65 through the three-way valve 66, the external unit 65 works to dissipate the heat of the flowing refrigerant, so as to avoid the refrigerant returning to the second liquid storage part 63 from overheating and affecting the dehumidification quality and efficiency of the evaporator part 20 after the output end of the second liquid storage part 63 outputs to the evaporator part 20.

[0067] It can be understood that the circulation channel groups 60 on both sides of the circulation channel 11 operate in coordination, so as to improve the energy utilization rate and assist in realizing the temperature regulation and dehumidification inside the plant factory.

[0068] In one embodiment, check valves 67 are arranged at the output end of the heat exchanger part and the output end of the external unit 65.

[0069] In order to prevent the refrigerant from flowing back into the heat exchanger section through the output end of the heat exchanger section or flowing back into the outdoor unit 65 through the output end of the outdoor unit 65 when the outdoor unit 65 transfers the refrigerant into the second liquid storage section 63, or when the refrigerant flowing out from the output end of the heat exchanger section is transferred into the second liquid storage section 63, one-way valves 67 are provided at both the output end of the heat exchanger section and the output end of the outdoor unit 65.

[0070] It can be understood that due to the presence of the one-way valves 67, the flow direction of the refrigerant from the outdoor unit 65 to the second liquid storage section 63 and the flow direction of the refrigerant from the heat exchanger section to the second liquid storage section 63 prevent the reverse flow of the refrigerant, thereby ensuring the stability of the refrigerant transmission.

[0071] In one embodiment, the heat exchanger section includes a heat recovery section 30 and a condensation section 50, and the heat recovery section 30 and the condensation section 50 are arranged in parallel in the flow channel 11.

[0072] Wherein, a circulation flow channel group 60 is provided between the heat recovery section 30 and the evaporator section 20, and a circulation flow channel group 60 is provided between the condensation section 50 and the evaporator section 20.

[0073] When the conventional dehumidification equipment in the plant factory is working, the heat generated by the equipment operation will affect the growth of the plants around the equipment.

[0074] Therefore, the heat exchanger section provided in the flow channel 11 of the present invention includes the heat recovery section 30 and the condensation section 50, which are used to recover 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 the energy utilization efficiency.

[0075] It can be understood that the heat exchanger section further includes a condensation section 50, and the condensation section 50 is arranged on the side of the evaporator section 20, so that the gas that has been dehumidified and cooled by the evaporator section 20 is heated and raised in temperature again by the condensation section 50, thereby preventing the gas flowing through the flow channel 11 for dehumidification from affecting the normal growth of the plants in the plant factory due to too low temperature.

[0076] It can be understood that by connecting the condensation section 50 and the evaporator section 20 through the circulation flow channel group 60, the refrigerant flowing through the evaporator section 20 can all flow back into the condensation section 50 under the guidance of the circulation flow channel, and the heat carried by the refrigerant is used to heat the gas again in the condensation section 50, thereby realizing the reuse of the recovered heat and improving the utilization efficiency of the heat.

[0077] In one embodiment, the evaporator section 20 includes a plurality of evaporator units, and the plurality of evaporator units are arranged in parallel at the channel entrance of the circulation channel 11.

[0078] As Figure 2 shown, the plurality of evaporator units are stacked in parallel at the channel entrance of the circulation channel 11, and the plurality of evaporator units cover and block the circulation channel entrance, so that the air inhaled into the circulation channel 11 by the blower wall 40 can all pass through the evaporator section 20 before flowing to the heat exchanger section, thereby ensuring the effect of dehumidifying the gas.

[0079] It can be understood that the plurality of evaporator units are arranged in a single row at the circulation channel entrance, which facilitates the evaporator section 20 to block the circulation channel.

[0080] It should be noted that the heat recovery section 30 and the condensation section 50 are arranged in a single row in the circulation channel and are located on one side of the evaporator section 20, so that the heat exchanger section can block the circulation channel, and the dehumidified and cooled gas can be heated and warmed by the heat exchanger section.

[0081] At the same time, the blower wall 40 includes a plurality of blower units, and the plurality of blower units are arranged in a single row at the circulation channel exit. When the plurality of blower units work, the gas is pumped from the entrance of the circulation channel to the exit of the circulation channel, so as to facilitate the dehumidification and temperature adjustment of the gas.

[0082] It can be understood that the evaporator section 20, the heat exchanger section and the blower wall 40 are integrally arranged in the circulation channel to facilitate the dehumidification and temperature adjustment of the gas, and the refrigerant circulation between the evaporator section 20 and the heat exchanger section is realized through the circulation flow channel, and the recycling of the recovered heat is realized, thereby reducing the equipment volume and cost while improving the energy utilization rate.

[0083] In one embodiment, an air duct 70 is formed between the heat exchanger section and the blower wall 40, and a fresh air flow channel 80 is provided on the machine body 10. The fresh air flow channel 80 communicates with the air duct 70, and the fresh air flow channel 80 extends out of the machine body 10.

[0084] It should be noted that since the plant factory is enclosed, it is necessary to perform regular ventilation operations on the interior of the plant factory.

[0085] It can be understood that an air duct 70 is provided between the heat exchanger section and the blower wall 40, so that external air can directly enter the plant factory along the fresh air flow channel 80, the air duct 70 and the circulation channel 11 during the operation of the blower wall 40.

[0086] It should be noted that the air duct 70 is formed between the heat exchanger part 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 press the gas into the air duct 70 through the fresh air duct 80, thereby avoiding the need to reinstall a fresh air unit in the machine body 10, reducing the cost of the machine body 10, and meeting the fresh air ventilation requirements at the same time.

[0087] It can be understood that when the fresh air enters the plant factory, the fresh air does not pass through the evaporator part and the heat exchanger part, thereby reducing consumption.

[0088] It can be understood 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 operates and the compressor part 64 does not need to be turned on. At this time, a negative pressure channel is formed at the air duct 70, so that external air can enter the plant factory through the fresh air duct 80 and the air duct 70, thereby reducing the energy consumption for temperature and humidity adjustment.

[0089] In one embodiment, a filter group is provided in the fresh air duct 80.

[0090] It can be understood that by providing a filter module in the fresh air duct 80, the fresh air can be filtered during the air intake process to improve the gas quality in the plant factory.

[0091] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
