According to the growth of various animal husbandry and aquaculture techniques, as well as the progress of agriculture and cultivation techniques, the cultivation or planting activities of various edible, ornamental and even medicinal animals and plants are almost no longer affected by the changes in natural solar terms. Taking planting plants as an example, in addition to the traditionally widely used "greenhouse", a desktop "plant growth box" for research or household use has been developed to enable relevant academics or industry professionals to The environment in the aforementioned "greenhouse" or "plant growth box" is regulated to study or verify the environmental conditions most suitable for the growth of a particular plant; in addition, "plants for large-scale cultivation of plants have been developed in recent years. Planting sites in the form of "factory" or "container house" can precisely control the environmental conditions of plant growth when planting plants in these "plant factories" or "container houses" with less external disturbance. Not only can we obtain better yield, but it can also effectively reduce the application of pesticides. Therefore, the fruits and vegetables produced can not only balance the quality and quantity of the products, but also greatly improve the safety of eating. At present, high-grade vegetables such as lettuce, American radish, and green tendril, strawberries, and other vanilla plants are As for the cultivation and cultivation of various plant-based medicinal materials, there have been cases of successful mass production through the above-mentioned planting forms. In addition, there are many related cases in various ornamental plants such as edible mushrooms or orchids.

It can be seen from the above description that the control of environmental conditions and the cultivation or planting activities of animals and plants under suitable growing conditions can indeed bring great economic benefits and benefit human beings. However, it is customary to regulate the temperature of environmental conditions. The humidity control culture system often consumes a lot of energy in order to maintain a constant ambient temperature and humidity, and it is necessary to improve it from the viewpoint of environmental protection.

We will only use the schematic diagram of the temperature and humidity control culture system to explain the operation mode and shortcomings of the conventional temperature and humidity control culture system. Referring to FIG. 1 , the conventional temperature and humidity control culture system includes a temperature control circuit 4 and an incubator 3 , wherein the temperature control circuit 4 includes a compressor 41 , a radiator 42 and a refrigeration system expansion valve. 43. The compressor 41 can perform a compression process on a refrigerant; the radiator 42 can receive the refrigerant flowing out of the compressor 41, and cause the refrigerant to perform a heat dissipation and temperature reduction process therein; the refrigeration system expansion valve 43 can The refrigerant received from the radiator 42 is subjected to expansion treatment, whereby the refrigerant after the expansion treatment is greatly cooled. A culture space 30 is formed in the culture tank 3. The culture space 30 is provided with a cooler 311, a heater 312 and a temperature and humidity controller 32. The cooler 311 is separately expanded with the refrigeration system through a cooling circuit. The valve 43 and the compressor 41 are connected to receive the low temperature refrigerant from the refrigeration system expansion valve 43 through the cooling circuit, and reduce the temperature and humidity in the culture space 30 by the low temperature refrigerant, or pass through the cooling circuit. The refrigerant is introduced into the compressor 41, so that the refrigerant can be returned to the temperature control circuit 4, and is again cooled by the temperature control circuit 4; the heater 312 can convert electrical energy into heat energy, thereby increasing the culture space 30. Temperature inside; temperature and humidity control The device 32 is electrically connected to the cooler 311 and the heater 312 to regulate the cooler 311 and the heater 312 according to the detected temperature and humidity in the culture space 30 to enable the cooling. The device 311 can reduce the temperature and humidity in the culture space 30 or enable the heater 312 to increase the temperature in the culture space 30. In the conventional temperature and humidity control culture system, when the compressor 41 compresses the refrigerant, the temperature of the refrigerant rises. Therefore, the heat sink 42 must be used to cool the refrigerant after the temperature rise. After the refrigerant is subjected to the expansion treatment of the refrigeration system expansion valve 43, the temperature of the refrigerant is much lower than the temperature before the refrigerant is compressed. By the foregoing process, the heat in the refrigerant can be continuously dissipated to the outside, so that the cooler 311 can continuously cool the culture space 30 by using the refrigerant at a low temperature.

As can be seen from the above description, in the conventional temperature and humidity control culture system, if the cooler 311 is to function, it is necessary to consume energy to drive the compressor 41 so that the compressor 41 can perform the refrigerant. The compression process; conversely, if the heater 312 is to function, it is necessary to consume energy (electric energy) to drive the heater 312 so that the heater 312 can convert electrical energy into heat energy, thereby increasing the culture space 30. The temperature inside. Obviously, in the process of lowering the temperature and humidity in the culture space 30, the heat of the refrigerant heated by the compression treatment of the compressor 41 is not efficiently utilized, but is meaninglessly It is distributed to the outside world, so that when it is necessary to raise the temperature in the culture space 30, the conventional temperature and humidity control culture system must additionally consume a large amount of electric energy to drive the heater 312 to generate heat energy, thereby improving the culture. The temperature within the space 30. It is not difficult to find from the above description that the conventional temperature and humidity control culture system fails to use the heat flow effectively in the process of regulating temperature and humidity, and the heat energy that may have been stored and utilized is discharged to the system. In addition, it has to spend a lot of extra energy to regenerate energy, which is very environmentally friendly.

In summary, how to improve the conventional temperature and humidity control culture system, so that the culture system can regulate the temperature and humidity of the environment in a way of energy-saving operation, and in turn, while pursuing economic benefits, taking into account the environmental protection purposes of energy conservation and carbon reduction, It is an important issue that the current relevant industry needs to work hard.

The first figure is a schematic diagram of the structure of the conventional temperature and humidity control culture system; and the second figure is a schematic diagram of the temperature and humidity control culture system of the energy-saving operation of the present creation.

The present invention is a temperature and humidity control culture system for energy-saving operation. Referring to FIG. 2, in a preferred embodiment of the present invention, the culture system includes an incubator 1 and a temperature control circuit 2 for controlling The temperature loop 2 regulates the temperature and humidity inside the incubator 1. A culture space 10 is formed in the incubator 1 to enable the user to cultivate a culture to be cultured therein (such as planting various plant or fungi, or even breeding animals). In particular, the incubator 1 herein refers to a variety of types of cultures that can be cultured in the culture space 10 therein, in other words, for desktop use for research or home use. "Aquaculture tanks" or "plant growth boxes", or "greenhouses" which are traditionally common, and even "plant factories" or "container houses" in the form of large-scale cultivation of plants can be regarded as what is referred to here. The incubator 1 is combined with Chen Ming. A first cooler 111 and a warmer 112 are disposed in the culture space 10 of the incubator 1 to regulate the temperature and/or humidity in the incubator 1 by the first cooler 111; or The warmer 112 regulates the temperature inside the incubator 1.

In the following, the introduction of the temperature control circuit 2 further explains how the culture system adjusts the temperature and humidity in the incubator 1 through the first cooler 111 and the warmer 112. The temperature control circuit 2 includes a first heat exchanger 211, a compressor 22, a second heat exchanger 212, a radiator 23, and a refrigeration system expansion valve 25. One of the refrigerants in the temperature control circuit 2 The elements can flow through the elements in sequence and form a circular path. The first heat exchanger 211 is connected to the first cooler 111 through a first cooling circuit, so that one of the first fluids in the first cooling circuit can travel to and from the first cooler 111. The first heat exchanger 211 is between. When the refrigerant in the temperature control circuit 2 flows into the first heat exchanger 211, the refrigerant is in a low temperature state (the reason is detailed later), and the refrigerant at a low temperature is in the first heat exchanger 211. Heat exchange with the first fluid. That is, the refrigerant that is subjected to the superheat exchange with the first fluid will enter the compressor 22. After the refrigerant enters the compressor 22, the compressor 22 compresses the refrigerant, and the temperature of the refrigerant after the compression treatment is greatly increased, so that the refrigerant is in a high temperature state, 嗣, high temperature The refrigerant will flow into the second heat exchanger 212. The second heat exchanger 212 is connected to the warmer 112 through a heating circuit to enable a second fluid in the heating circuit to travel to and from the warmer 112 and the second heat exchanger 212. between. After flowing into the second heat exchanger 212, the high temperature refrigerant will exchange heat with the second fluid in the second heat exchanger 212. That is, the refrigerant exchanged with the second fluid for heat exchange will enter the heat sink 23, and more heat is dissipated to the outside in the heat sink 23. When the refrigerant in the temperature control circuit 2 dissipates part of the heat to the outside and enters the refrigeration system expansion valve 25, the refrigeration system expansion valve 25 will expand the refrigerant, and the refrigeration system expansion valve During the expansion treatment of the refrigerant, the temperature of the refrigerant is greatly reduced, so that the refrigerant exhibits a low temperature state, and the refrigerant in a low temperature state flows into the first heat exchanger 211 to complete the This circulation path of the temperature control circuit 2.

As can be seen from the above description, in the circulation path, when the refrigerant flows into the first heat exchanger 211 from the refrigeration system expansion valve 25, the refrigerant is in the lowest temperature state; otherwise, when the refrigerant is compressed by the refrigerant When the machine 22 flows into the second heat exchanger 212, the refrigerant system is The highest temperature state. In other words, when the refrigerant exchanges heat with the first fluid in the first heat exchanger 211, the heat energy in the first fluid can be largely taken away, so that the first fluid can be sufficiently cooled. The first cooling circuit flows into the first cooler 111, thereby enabling the first cooler 111 to regulate the temperature or humidity in the incubator 1; otherwise, when the refrigerant is in the second heat exchanger 212 When heat exchange is performed with the second fluid, a large amount of thermal energy can be transferred to the second fluid, so that the second fluid that has sufficiently warmed can flow into the warmer 112 via the heating circuit, thereby The warmer 112 can regulate the temperature in the incubator 1 accordingly.

Referring to FIG. 2, in the preferred embodiment, a first flow control valve 131 is disposed on the first cooling circuit for performing flow control on the first fluid, and the heating circuit is on the heating circuit. A second flow control valve 132 is provided for controlling the flow rate of the second fluid. Further, the culture space 10 is further provided with a temperature and humidity controller 121, and the temperature and humidity controller 121 is coupled to the first flow control. The valve 131 and the second flow control valve 132 are electrically connected. The temperature and humidity controller 121 stores a first temperature setting value and can detect the temperature and humidity in the culture space 10, and the temperature and humidity controller 121 can detect the temperature in the culture space 10 detected, The first temperature set values are compared, and the first flow control valve 131 and the second flow control valve 132 are accordingly regulated.

For example, the application of this creation to the cultivation of strawberries is used as an example to illustrate the temperature and humidity control method of the cultivation system when the plant is planted with the energy-saving operation temperature control system of the present invention. Generally speaking, the optimum temperature and humidity conditions corresponding to the respective growth stages of strawberries are as follows: (1) Growth period: daytime temperature is about 20 to 25 °C, night temperature is about 15 to 18 °C, relative humidity (Relative Humidity, referred to as RH) about 80%; (2) flowering period: daytime temperature is about 20 to 25 °C, night temperature is about 15 to 18 ° C, relative humidity is about 50%; (3) fruit expansion period: daytime temperature is about 22 to 25 ° C, night temperature is about 12 to 15 ° C, relative humidity is about 80%; and (4) fruit Maturity: The daytime temperature is about 20 to 24 ° C, the night temperature is about 8 to 10 ° C, and the relative humidity is about 80%.

Taking the growth period as an example, if the temperature in the culture space 10 is higher than 25 ° C, the temperature and humidity controller 121 controls the first flow control valve 131 to make the first fluid in the first heat exchanger 211 It can flow to the first cooler 111 in a large amount. As described above, since the refrigerant is in a low temperature state in the first heat exchanger 211, the heat energy in the first fluid can be largely taken away to sufficiently cool the first fluid, so that when the first heat exchange is performed The first fluid in the device 211 flows to the first cooler 111 in a large amount, and the first cooler 111 can perform a cooling operation on the culture space 10 by using the first fluid that is sufficiently cooled, thereby further cultivating the culture space. The temperature within 10 can be lowered to a temperature suitable for strawberry growth.

Continued, taking the flowering period as an example, since the ambient humidity condition most suitable for the flowering period is much lower than other stages, the first cooler is maintained so that the relative humidity in the culture space 10 can be maintained at about 50%. 111 The time for performing the cooling operation (while lowering the relative humidity in the culture space 10 while cooling) will be slightly longer than other growth stages, and thus, the temperature in the culture space 10 may continue to decrease. It is lower than the ideal temperature that is most suitable for flowering. Therefore, if the daytime temperature in the culture space 10 is lower than 20 ° C, or the night temperature in the culture space 10 is lower than 15 ° C, the temperature and humidity controller 121 controls the second flow control valve 132 to The second fluid in the second heat exchanger 212 can flow to the warmer 112 in a large amount. As described above, since the refrigerant is in a high temperature state in the second heat exchanger 212, a large amount of thermal energy can be transferred to the second fluid to sufficiently heat the second fluid, so that when the second heat exchange The second fluid in the device 212 flows in a large amount to the warmer 112, the warmer 112, the second fluid which is sufficiently heated can be used to perform a warming operation on the culture space 10, and the temperature in the culture space 10 is raised back to a temperature suitable for strawberry flowering.

As can be seen from the above description, the temperature and humidity control in the culture space 10 can be achieved through a single temperature control circuit 2, and after the refrigerant is compressed by the compressor 22 and heated, the thermal energy can also pass through the first The heat exchanger 212 is efficiently utilized, and the temperature in the culture space 10 is adjusted accordingly, without separately installing a heater in the culture space 10, so that the heater can be prevented from being installed. It takes extra energy to generate heat energy. Therefore, through the creation of the energy-saving operation temperature and humidity control and cultivation system of this creation, it will be able to effectively achieve the environmental protection goal of energy saving and carbon reduction.

And a temperature controller 122, wherein the second cooler 113 is connected to the first heat exchanger 211 through a second cooling circuit to enable a third fluid in the second cooling circuit to reciprocate Between the second cooler 113 and the first heat exchanger 211, the third fluid can be exchanged with the refrigerant in the first heat exchanger 211. The temperature controller 122 is electrically connected to a third flow control valve 133 disposed on the second cooling circuit, and the third flow control valve 133 is configured to perform flow control on the third fluid. The temperature controller 122 stores a second temperature setting value, and the temperature controller 122 can detect The temperature of the culture solution in the culture tank 14 can further compare the detected temperature of the culture solution in the culture solution tank 14 with the second temperature set value, and accordingly the third flow rate Control valve 133 is regulated to control the flow of the third fluid in the second cooling circuit. Thus, when the user grows the plant through planting techniques such as soilless cultivation, medium tillage, hydroponic or drip irrigation, the temperature of the culture solution in the culture tank 14 can be adjusted by the temperature controller 122, thereby providing appropriate The temperature of the culture medium is given to the plant to be planted.

As described above, since the temperature in the culture space 10 and the liquid temperature in the culture tank 14 are respectively regulated by the temperature and humidity controller 121 and the temperature controller 122, and the temperature and humidity controller 121 and the temperature controller 122 The first temperature setting value and the second temperature setting value are respectively stored, so that when a particular plant is planted by the culture system of the present invention, the environment can be accurately adjusted according to the environmental conditions optimal for the growth of the plant. The temperature and liquid temperature, in turn, enable the plant to grow well. In general, since the liquid temperature of the natural environment or the temperature of the soil is slightly lower than the temperature, in the preferred embodiment, the second temperature setting is lower than the first temperature setting to accurately simulate the real The various temperature and humidity conditions in the natural environment, so that the environmental conditions in the incubator 1 can fully meet the environmental conditions most suitable for plant growth.

However, depending on the needs of the actual application, in other embodiments of the present invention, a partition design may be provided in the first heat exchanger 211 to make the first fluid And the third fluid can be independent of one another, as specified herein. In addition, in order to effectively maintain the The cooling effect of the refrigerant on the first and/or third fluid, in the preferred embodiment, the temperature control circuit 2 further includes a refrigeration system dryer 24 for removing the refrigerant from the refrigeration system dryer 24. The moisture can further maintain the refrigerant in a relatively dry state to maintain the cooling effect that the refrigerant can achieve.
