Description

Temperature control devices and greenhouse systems

The invention relates to a temperature control device and a greenhouse system. Specifically, the present invention relates to a temperature control device utilizing the underground constant temperature phenomenon and a greenhouse system using the temperature control device.

In order to avoid damage to crops caused by unsuitable weather (such as spring rains, plum rains, typhoons, and cold snaps), many businesses have switched to growing crops in greenhouses. Generally speaking, the roof of the greenhouse will be covered with plastic film or transparent corrugated board to prevent rain and provide sunlight at the same time, and the greenhouse will be surrounded by insect-proof netting to prevent pests from entering the greenhouse. However, greenhouses built in this way will have poor ventilation inside, and the temperature inside will continue to rise due to sunlight (in some cases, the temperature inside the greenhouse will be higher than the temperature outside the greenhouse More than ten degrees Celsius), causing crops to be difficult to grow or even die due to high temperatures.

Currently, there are two technical solutions to solve the problem of high temperatures in summer faced by greenhouses, namely fan water wall and fan spray system. If a fan water wall is used, a fiber paper wall needs to be built on one side of the greenhouse (when the fan water wall is operating, this side is the air inlet), allowing circulating water to pass through each fiber paper gap from top to bottom to form water. Wall, a large negative pressure fan needs to be built on the opposite side of the side (i.e., opposite the water wall), and the remaining two sides need to be sealed with plastic film. When the negative pressure fan starts to draw air, the hot air from the outside will interact with the water in the fiber paper gaps when passing through them. Change the air entering the greenhouse into cool breeze. The fan mist system uses the principle of hot air rising and cold air falling. If a fan spray system is used, several rows of high-pressure pipes need to be built above the interior of the greenhouse. Each row of high-pressure pipes is equipped with multiple aerosol nozzles. A high-pressure motor is then used to atomize the water, allowing the water molecules to absorb ambient heat when they evaporate to achieve the desired effect. Cooling effect.

Although a fan water wall or a fan mist system can be used to cool a greenhouse, both of these technical solutions require professionals to build and are expensive. In addition, the operation of the fan water wall and fan spray system consumes a lot of power, which not only puts a burden on the power supply system, but also incurs high electricity bills. Furthermore, both the fan water wall and the fan mist system can only cool down the greenhouse, but cannot insulate or heat the greenhouse. Therefore, they cannot solve the problem of low temperature in winter faced by the greenhouse.

In view of this, there is still an urgent need in this field for a temperature control device and greenhouse system that can provide functions such as cooling, heating, and heat preservation, has low power consumption, is easy to construct, and is low-cost.

The temperature control device and greenhouse system provided by the present invention will be explained below through implementation modes, but these implementation modes are not intended to limit the invention to be implemented in any environment, application or method as described in these implementation modes. The description of the following embodiments is only for the purpose of explaining the present invention and is not intended to limit the scope of the present invention. It should be understood that in the following embodiments and drawings, elements not directly related to the present invention have been omitted and not described or/and illustrated. In addition, the size of each element and the proportional relationship between the elements in the drawings are only for convenience of illustration and explanation, and are not used to limit the scope of the present invention. Furthermore, unless otherwise stated, "a", "the" and similar terms used in this specification and the patent claims shall be understood to include both the singular and the plural.

Figure 1 is a schematic diagram of a greenhouse system GS in some embodiments of the present invention. The greenhouse system GS includes a greenhouse GH and a temperature control device 1 . The temperature control device 1 includes a fan 11, a box 13, two ventilation ducts 15, 17 and four fiber screens 191, 193, 195, 197. Figure 2 is an enlarged schematic diagram of the cabinet 13 and the fiber screens 191, 193, 195, and 197.

The temperature control device 1 is used to control the temperature in the greenhouse GH to prevent the temperature in the greenhouse GH from being too high or too low, so the fan 11 is installed in the greenhouse GH. The fan 11 has an air inlet 11a and an air outlet 11b, and the air outlet 11b faces the inside of the greenhouse GH. It should be noted that the present invention does not limit the height of the fan 11 in a space (in this embodiment, the greenhouse GH). However, in order to achieve a better temperature control effect, the height of the fan 11 can be determined based on the principle that hot air rises and cold air falls. 11 height. That is, if you want to use the temperature control device 1 to cool down the greenhouse GH, the fan 11 can be installed at a higher place in the greenhouse GH. If you want to use the temperature control device 1 to heat up or maintain the temperature of the greenhouse GH, the fan 11 can be installed at a lower place in the greenhouse GH.

This new system takes advantage of the relatively stable temperature characteristics of the ground G. Taking Taiwan as an example, the temperature in the shallow underground (for example, 2 to 50 meters underground) is about 18 to 20 degrees Celsius in summer and about 15 to 18 degrees Celsius in winter. In order to utilize the stable temperature under the ground G, the box 13 is arranged under the ground G. It should be noted that this model does not limit the depth D1 of the box 13 under the ground. In some embodiments, the depth D1 of the box 13 may be at least two meters to reduce the impact of the temperature on the ground G on the box 13 . The box 13 has an accommodation space, so it can accommodate liquid (for example, water). The box 13 has two openings 13a and 13b, and the opening 13a and the opening 13b are located on opposite sides of the box 13 (ie, two opposite sides of the box 13). This new model does not limit the material of the box 13. For example, the material of the box 13 can be cement, polyvinyl chloride (PVC), or metal, but is not limited thereto.

The ventilation pipe 15 has an inlet 15a and an outlet 15b, wherein the inlet 15a is provided above the ground G, and the outlet 15b is connected to the opening 13a of the box 13. The present invention does not limit the height H1 of the inlet 15a of the ventilation duct 15 (ie, the distance between the inlet 15a and the ground G). However, if the temperature control device 1 is used to reduce the temperature of the greenhouse GH, the height H1 of the inlet 15a can be less than a preset height (that is, the inlet 15a should not be too far from the ground G). This is based on the fact that the hot air rises and the cold air The principle of descent. In addition, the ventilation pipe 17 has an inlet 17a and an outlet 17b, wherein the inlet 17a is connected to the opening 13b of the box 13, and the outlet 17b is connected to the air inlet 11a of the fan 11. This new model does not limit the materials of the ventilation pipelines 15 and 17. For example, the material of the ventilation pipes 15 and 17 can be polyvinyl chloride, but is not limited to this.

The top of the box 13 and the ventilation pipes 15 and 17 is covered with a substance (such as soil, but not limited to this), and can be covered until it is aligned with the ground G or until the height difference between the ground G and the ground G is small. Within a preset gap (ie, tolerance value) to reduce the influence of the temperature on the ground G on the box 13 and the ventilation ducts 15 and 17 .

Fiber screens 191, 193, 195 and 197 are arranged in the box 13. When the box 13 contains liquid, a portion (for example, the bottom) of the fiber screens 191, 193, 195, and 197 is immersed in the liquid. It should be noted that the present invention does not limit the material of the fiber screens 191, 193, 195, and 197, but the fiber screens 191, 193, 195, and 197 are fibers that can undergo capillarity when exposed to liquid. For example, the fiber screens 191, 193, 195, and 197 can be towels, but are not limited to this. In addition, the present invention does not limit the number of fiber screens included in the temperature control device 1, and does not limit the spacing of the fiber screens. However, the greater the number of fiber screens, the better the temperature control (ie, cooling or heating) effect. In addition, the smaller the spacing between the fiber screens, the better the temperature control (ie, cooling or heating) effect.

The present invention does not limit the fixing methods of the fiber screens 191, 193, 195 and 197. In some embodiments, the fiber screens 191, 193, 195, 197 can be fixed as shown in Figure 2. In these embodiments, the fiber screens 191, 193, 195, and 197 are each fixed by two fixing devices (for example, fixed crossbars), and one of the fixing devices is located above the other fixing device. As shown in Figure 2, the fiber screen 191 is fixed by the fixing devices 21a and 21b, and the fixing device 21a is located above the fixing device 21b; the fiber screen 193 is fixed by the fixing devices 23a, 23b, and the fixing device 23a is located above the fixing device 23b ; The fiber screen 195 is fixed by the fixing devices 25a, 25b, and the fixing device 25a is located above the fixing device 25b; the fiber screen 197 is fixed by the fixing devices 27a, 27b, and the fixing device 27a is located above the fixing device 27b. In these embodiments, the lower fixing devices 21b, 23b, 25b, 27b can be placed directly on the bottom of the box 13 (for example: the fixing devices 21b, 23b, 25b, 27b can be integrated into a base, placed placed at the bottom of the box 13).

Before using the temperature control device 1 to control the temperature in the greenhouse GH, a liquid (not shown) (eg, water) can be stored in the box 13 . In order to maintain the fluidity of the air, the height of the liquid in the box 13 does not exceed the height OH1 of the lower edge of the opening 13a, and does not exceed the height OH2 of the lower edge of the opening 13b. The aforementioned heights are relative to the bottom of the box 13. As mentioned above, a portion (eg, the bottom) of each of the fiber screens 191, 193, 195, and 197 is immersed in the liquid.

When the fan 11 operates (ie, draws air), air with a first temperature (not shown) enters the temperature control device 1 through the inlet 15a of the ventilation duct 15, and sequentially passes through the ventilation duct 15 and the fibers in the box 13. The screens 191, 193, 195, 197 and the ventilation duct 17 discharge air with a second temperature (not shown) from the air outlet 11b of the fan 11. The path of air flow is shown by the arrows inside the ventilation duct 15, the box 13, the ventilation duct 17 and the greenhouse GH in Figure 1. When the air flows through the ventilation duct 15, the fiber screens 191, 193, 195, 197 of the box 13 and the ventilation duct 17, the temperature of the air will be affected by the temperature below the ground G, and the air will interact with the fiber screens 191, 193, The liquid in the gaps 195 and 197 exchanges heat, so the temperature of the air will change from the first temperature to the second temperature (that is, the first temperature and the second temperature are different).

As mentioned above, since the temperature under the ground G is relatively stable, when the external environment is hot, the temperature control device 1 can cool down the greenhouse GH, and when the external environment is cold, the temperature control device 1 can cool down the greenhouse GH. Keep warm or warm. The fiber screens 191, 193, 195, and 197 provided in the box 13 are used to provide heat exchange to enhance the effect of temperature control (ie, cooling, heating, and heat preservation).

Figure 3 shows a schematic diagram of the greenhouse system GS in some other embodiments of the present invention. In these embodiments, the temperature control device 1 not only includes the fan 11, the box 13, the ventilation ducts 15, 17, and the fiber screens 191, 193, 195, 197, but also includes a liquid supply device 31, A detection pipeline 33 and a liquid level controller 35 are used to further monitor the liquid level in the tank 13 (specifically, the liquid level of the liquid contained in the tank 13), and maintain the liquid level in a timely manner. It should be noted that in order to facilitate the presentation of other components included in the temperature control device 1, the fiber screens 191, 193, 195, and 197 provided in the box 13 are not shown in Figure 3.

Specifically, the top surface of the box 13 has an opening 13c. The detection pipe 33 has two pipe openings 33a and 33b. The detection pipeline 33 is arranged vertically (that is, perpendicular to the ground G), with the tube opening 33a located above the ground G, and the tube opening 33b connected to the opening 13c of the box 13 . The present invention does not limit the material of the detection pipeline 33. For example, the material of the detection pipeline 33 can be polyvinyl chloride.

The liquid supply device 31 includes a motor (for example, a water pumping motor) 311 and a supply pipeline 313 , wherein the supply pipeline 313 is disposed between the motor 311 and the box 13 . For example, the supply pipeline 313 has a first pipe opening and a second pipe opening, wherein the first pipe opening can be connected to the motor 311, and the second pipe opening is connected to the side wall of the detection pipe 33, and is connected via A part of the detection pipeline 33 leads to the box 13, as shown in Figure 3. In some embodiments, the second opening of the supply pipe 313 may be connected to another opening of the box 13 (not shown). The present invention does not limit the material of the supply pipeline 313. For example, the material of the supply pipeline 313 may be polyvinyl chloride.

The liquid level controller 35 includes floats 351, 353 and wires 355. One end of the wire 355 is connected to the motor 311, and the other end is connected to the floats 351, 353. The float balls 351 and 353 are arranged at a first preset height and a second preset height in the box 13 through the detection pipeline 33 (specifically, the wires 355 are used to make the float balls 351 and 353 pass through the detection pipeline 33 and suspended at a first preset height and a second preset height). The aforementioned first preset height and the second preset height refer to the heights of the floats 351 and 353 relative to the bottom of the box 13 respectively, where the first preset height is lower than the second preset height.

In these embodiments, when the liquid level in the tank 13 is lower than the first preset height, the position of the float 351 changes, causing the floats 351 and 353 to come into contact with electricity, thus causing the liquid level controller 35 to drive the motor. 311, the motor 311 starts to operate to provide liquid (for example, water) into the tank 13 through the supply pipe 313 until the liquid in the tank 13 reaches the second preset height.

By arranging the liquid supply device 31, the detection pipeline 33 and the liquid level controller 35, the temperature control device 1 can automatically monitor the liquid level in the box 13 and maintain the liquid level in a timely manner to maintain temperature control (i.e., cooling, heating, and heat preservation) effects.

Figure 4 shows a schematic diagram of a greenhouse system GS in some other embodiments of the present invention. In these embodiments, the temperature control device 1 includes a fan 11, a box 13, ventilation pipelines 15, 17, fiber screens 191, 193, 195, 197, a liquid supply device 31, a detection pipeline 33 and a liquid level control. The device 35 further includes other components to provide another mechanism for monitoring and maintaining the liquid level in the tank 13 . It should be noted that in order to facilitate the presentation of other components included in the temperature control device 1, the fiber screens 191, 193, 195, and 197 provided in the box 13 are not shown in Figure 4.

In these embodiments, the top surface of the box 13 has another opening 13d. The temperature control device 1 also includes another detection pipeline 41 . The detection pipe 41 has pipe openings 41a and 41b. The detection pipeline 41 is arranged vertically such that the pipe opening 41a is located above the ground G, and the pipe opening 41b is connected to the opening 13d. The present invention does not limit the material of the detection pipeline 41. For example, the material of the detection pipeline 41 may be polyvinyl chloride.

In some embodiments, a strip-type detection object (not shown) can be extended into the tank 13 through the detection pipeline 41 to detect the liquid level in the tank 13 . For example, the user can extend a wooden bar into the detection pipe 41 to reach the bottom of the box 13, then pull out the wooden bar, and determine the liquid level in the box 13 from the wetted part of the wooden bar. In these embodiments, when the user determines through the strip detection substance If the liquid level in the box 13 is too low, the liquid can be replenished into the box 13 through the nozzle 41a of the detection pipe 41, or the motor 311 can be manually started to provide liquid into the box 13.

In some embodiments, at least one cooling object (for example, ice cubes) can be put into the box 13 through the nozzle 41a of the detection pipe 41 to increase the cooling effect.

By providing another mechanism for monitoring and maintaining the liquid level in the tank 13 , when the liquid level controller 35 fails and cannot detect the liquid level in the tank 13 , the user can still determine the level of the tank 13 through the detection pipeline 41 the liquid level inside and maintain the liquid level in a timely manner. In this way, it is possible to avoid affecting the temperature control (ie, cooling, heating, and heat preservation) effects due to the reduction of liquid in the box 13 .

It should be noted that, considering the construction cost, in some embodiments, the temperature control device 1 can also be changed to not include the liquid supply device 31, the detection pipeline 33 and the liquid level controller 35, but only the detection pipeline 41. To monitor and maintain the liquid level in the tank 13.

Figure 5 shows a schematic diagram of a greenhouse system GS in some other embodiments of the present invention. It should be noted that in order to facilitate the presentation of other components included in the temperature control device 1, the fiber screens 191, 193, 195, and 197 provided in the box 13 are not shown in Figure 5.

In these embodiments, the ventilation pipeline 15 includes a first part 151 and a second part 153, and the first part 151 and the second part 153 are connected. The first part 151 extends from below the ground G to above the ground G, and the second part 153 is located below the ground G. In these embodiments, the second portion 153 may include at least one U-shaped tube to increase the time the air remains below the ground G. Similarly, the ventilation pipeline 17 includes a first part 171 and a second part 173, and the first part 171 and the second part 173 are connected. The first part 171 extends from below the ground G to above the ground G, and the second part 173 is located below the ground G. In these embodiments, the second portion 173 may include at least one U-shaped tube to increase the time the air remains below the ground G.

Since the parts of the ventilation pipes 15 and 17 located below the ground G adopt a U-shaped pipe design, the air stays below the ground G for an extended period of time after entering the temperature control device 1, which means that the air is affected by the temperature below the ground G. Time increases. Therefore, the temperature control device 1 can provide better temperature control (ie, cooling, heating, and heat preservation) effects.

In some embodiments, the portion of the first portion 151 of the ventilation duct 15 that extends above the ground G can be covered by a temperature stabilizing plate C1 to reduce the impact of the external temperature on the ground G on the first portion 151 . Similarly, the part of the first part 171 of the ventilation duct 17 that extends out of the ground G may be covered by a temperature stabilizing plate C2 to reduce the impact of the external temperature on the ground G on the first part 171 . By arranging the temperature stabilizing plates C1 and C2 to reduce the degree to which the air is affected by the temperature on the ground G, the temperature control device 1 can provide better temperature control (ie, cooling, heating, and heat preservation) effects.

It should be noted that although the above embodiments take the greenhouse system GS as an example to illustrate how the temperature control device 1 controls the temperature in the greenhouse GH, it should be understood that the temperature control device 1 of the present invention can also be used to control other fields/spaces. temperature. If the temperature control device 1 is to be used to control the temperature of other fields/spaces, the fan 11 will be installed in the field/space.

To sum up, the temperature control device provided by the present invention takes advantage of the relatively stable temperature characteristics of the ground to control the temperature of a space (such as a greenhouse). When the external environment is hot, the temperature control device uses the temperature under the ground to cool down a space. When the external environment is cold, the temperature control device uses the temperature under the ground to keep or heat up a space. The fiber screen installed in the box of the temperature control device is used to provide heat exchange to enhance the effect of temperature control (ie, cooling, heating, and heat preservation). The new temperature control device of the present invention can also have different mechanisms to monitor the liquid level in the box and maintain the liquid level in a timely manner to maintain the temperature control effect. In addition, by using a U-shaped pipe design for the part of the ventilation pipe located below the ground, the time for the air to be affected by the temperature below the ground can be increased, thereby allowing the temperature control device to provide better temperature control effects. Furthermore, if the part of the ventilation duct located above the ground is covered with a temperature stabilizing board, it can reduce the degree to which the air is affected by the temperature on the ground and provide better temperature control effects.

In addition, using the temperature control device provided by the present invention, before the air enters a space (such as a greenhouse), the temperature of the air has changed from the original first temperature to the second temperature. Therefore, compared with the conventional technology, the temperature control The power consumption of the device's fan operation will be significantly reduced. Furthermore, compared with the conventional technology, the temperature control device provided by the present invention and the environment (such as a greenhouse system) using the temperature control device of the present invention can be constructed in a simpler manner.

The above-mentioned embodiments are used to illustrate some implementation aspects of the present invention and to explain the technical features of the present invention, but are not used to limit the scope and scope of protection of the present invention. Any changes or equivalents that can be easily accomplished by a person with ordinary knowledge in the technical field to which this invention belongs The arrangements all fall within the scope claimed by this new model, and the scope of rights protection of this new model shall be subject to the scope of the patent application.
