Description

[Detailed Description of the Invention] The amount of petroleum used in greenhouse cultivation is extremely large, but since the oil crisis, energy conservation has increased,
An effective method for this is the use of solar heat. In particular, the geothermal heat exchange heating system related to the present invention has low equipment costs and has shown initial practical effectiveness in terms of heat storage effect; however, there is still room for further research. On the other hand, the drawback is that when extracting geothermal heat at night, the humidity inside the greenhouse increases, and when the outside temperature is low, condensation forms on the inner walls of the greenhouse, leaves and fruits of crops such as tomatoes and cucumbers. However, the activation of bacteria and fungi caused epidemics and decreased respiratory function.

In addition, in order to increase the heat storage effect underground during the day, ventilation is suppressed as much as possible, resulting in a lack of Co, and the upper row of humidity at night and the lack of Co during the day cause this /stem dog^^ defect. It had become. The first to fourth inventions further enhance the thermal efficiency of these seven stems, lower the humidity in the greenhouse at night, effectively suppress high temperatures in the room during the day, and also reduce CO and concentration during the day. Raise,
The purpose of this device is to adsorb and remove bacteria and mold, and to do this in an energy-saving manner.

In order to achieve the above object, the present invention is based on the adsorption of alumina gel, synthetic zeolite, activated carbon, etc. alone or in a mixed state as an adsorption material that can be easily regenerated by heating. Attach a center-rotating type blower pipe, and use the blower □!□ for dehumidification (adsorption) and regeneration (detachment).
A cooler and a humidifier for enthalpy reduction are installed at the outlet of the adsorption layer to dehumidify, humidify,
The regeneration is switched during the corner adjustment time of the humidistat set indoors and at the set temperature of the thermostat that instructs the decrease in adsorbent capacity (reduction in heat of adsorption), and the end of regeneration and the start of dehumidification. The heat source for regeneration is a high-pressure burner with a high-load small combustion furnace of Patent Application No. 62953 filed in 1981. This is an environment control device for indoor and medium heat exchange type hot water room heating.

The second invention is to provide an underground heat storage blower pipe with a large number of holes or outlets, and to create a layer of natural colloidal soil, chabazite, etc. on the outside of the pipe, or to use the pipe to create a layer of colloidal soil, chabazite, etc. Create a layer of chabazite, etc., and guide the warm air to store heat into this layer.
Due to the strong water absorption power of this material, it absorbs condensed moisture and t41-F water that occur during heat storage, prevents water from entering the pipes, and improves air circulation within the heat storage tank. This is an underground heat storage device for a greenhouse, which is characterized by improving heat storage and heat exchange effects.

NXA's invention suppresses the high temperature inside the greenhouse during the day by adsorbing and removing moisture and harmful substances using multifaceted adsorption F-rings in the same manner as in Section 1. The adsorption layer is cooled with a water cooler set at the outlet tj, and the enthalpy of the air is also lowered, and this low humidity (RH 20% or less), low enthalpy air is set indoors (7) using water droplets from a humidifier or fine g generator. The strong heat of vaporization of this air cools the indoor air, controlling the temperature and humidity inside the greenhouse to the best environment for cultivation, and the water that has absorbed heat is stored outside the greenhouse instead of being discarded. This is done by cooling with a girder cooling tower and circulating it.
This is a greenhouse cooling and environmental device featuring:

The fourth invention is to circulate indoor or outdoor air related to underground heat exchange type rear room heating on the same multi-curved floor as in the first item, and to eliminate substances harmful to cultivation, such as excessive moisture. COL,
Adsorb and remove NH, FOHO, harmful fungi, residual gas from disinfectants, etc. (7. Thermostat, humiguistat, gas full). Continuously control the best environment for cultivation using I'ip, etc., and remove the adsorbent. Revival of 1975
The high-pressure burner with a high-load combustion furnace disclosed in Patent No. 62953 of 2013 is also used as a CO generator, and a part of the waste heat is released into the heating chamber during the regeneration of the small absorbent during the entire working day. This is a heat storage and environment adjustment device for an underground heat exchange type greenhouse 11iff, which is characterized by replenishing heat and storing most of the waste heat underground.

In the inventions of Items 1 and 4, the Metalit using the high-load small-sized hard-burning furnace-equipped Takao burner of Patent I No. 62953 of 1980 is as follows. That is, conventionally, Yonkuma electric heat was used as a regenerating heat source for adsorbent, and 110
This type of device using 0K/Hr power was not uncommon. However, current energy conditions do not allow this, and there are few examples of large-scale equipment of this kind being used in agriculture, so research and development of this heat source has not been carried out. In the present invention, due to the recent energy situation and new developments related to agriculture, it was necessary to solve this problem in order to achieve practical effects. In the present invention, the previously applied ``High Pressure Burner with High Load Compact Combustion Furnace'' is used as the heat source for regenerating the adsorbent. Its features are as follows.

(1) The combustion furnace is small and has a large capacity, and the load factor is 30 to 50 times that of a normal combustion furnace.

(2) The flame is short, complete combustion occurs in the combustion furnace, and the temperature reaches 1000℃.
(3) The pressure of the hot gas is high (400 to 2000 rula)
q) Therefore, it has the ability to sufficiently overcome the pressure resistance of the adsorbent layer during regeneration and the underground heat storage layer of waste hot air.

(4) Hot air generated from a burner can be immediately sent to the adsorption layer without using a heat exchanger.

(5) The temperature of the hot gas can be easily adjusted by introducing excess air using an ejector or the like to bring it to a temperature suitable for regeneration (500'C).

48) is a damper for dehumidified air, (49) is a damper for regenerated air, and (50) is a regenerated exhaust outlet.

Next, to explain the operation of the first invention, the structure of the underground heat exchange type greenhouse (1), which is the premise of the present invention, is usually a double structure made of transparent plastic, glass, etc. The relationship between the warmth of the inner wall and the outside temperature IW is +3°C in Yoshinaga where the outside air is -5°C. Therefore, the air beam in the greenhouse (1) in contact with the inner wall is P, 3″C,
If the indoor temperature rises to 15°C, dehumidification will occur to prevent condensation by reducing the humidity to below RH40'1. Further, dew condensation on plants can be prevented by reducing the relative humidity in the greenhouse (1) to 80 degrees or less. According to experiments,
1 in Figure 1. When we dehumidified the greenhouse for 10 to 12 hours by operating a device using 500 KF of adsorbent and regenerating it once at night in a 100m greenhouse (1), we found that this environment Maintain and Greenhouse (1)
It was possible to completely prevent dew condensation from forming on the inner walls and plants. A specific example of this is shown in FIG.

Regarding the second invention, the underground heat storage pipe (7) is made perforated, and the outer periphery of the pipe (7) is filled with a moisture absorbing and heat storage material, that is, a substance made of colloid, chabazite, etc. Make a layer (5) of u or more, and pour this 1 through the hole (9) of the pipe.
- It is a system that sends warm air during the day, regenerated waste heat of the adsorbent, and condensed water in the pipes to be stored inside. The conventional pipes that send hot air into the greenhouse (1) during the daytime have a lot of infiltration of ground F water and the outflow of heat (because there is no water absorbing material), so it is not possible to make the pipes perforated. There wasn't. According to the present invention, there is no condensation of water inside the pipe, preventing the intrusion of groundwater, and there is no movement of heat due to the flow of water, instead of using only convection heat transfer inside the pipe as in the past. However, in the present invention, the thermal efficiency is significantly increased by direct use of the heat absorbing and heat storage material. The reason why this absorbent and heat storage material is particularly adopted in the present invention is that it has a large absorption amount, and when it absorbs water, it absorbs the condensation heat and heat of wetting of the human eye.
9, in terms of physical properties, it has a specific heat capacity and low thermal conductivity compared to soil and the conventionally used chestnut stone, which means that if the latent heat from water absorption can be used, it can store a large amount of heat at 4V. , has little heat diffusion, has a heat insulating effect, and has a strong water absorption power that absorbs ground F water and condensed water, prevents heat transfer due to flow, and raises ground temperature. This is for reasons such as reducing the burden on the moisture adsorption device (6). Its physical properties are shown in Table 1.

Table 1 Comparative material names for heat retention (thermal storage) materials Specific heat Thermal conductivity Air circulation Insulating water absorption rate Kurite 0.22 0.7~09 Yoshi Nashinashi The indoor temperature during the day is usually over 30℃, and this Storing heat from high-temperature air underground is a conventional method, but in the present invention, the adsorbent is heated and regenerated at the same time as the stiffening.
The feature is that most of the waste heat at a high temperature of ~90°C is sent underground, but in the case of normal adsorption dehumidification equipment, all of this abandoned track is disposed of into the outside air, but in the present invention, This heat is stored underground and this energy is used at night, so 100.000 to 160.000 eal/da',
y or more can be used effectively.

Therefore, when the outside temperature is below 15°C, the indoor temperature cannot rise above 8°C using conventional methods, so heating must be performed. According to the method of the present invention, this heating is not necessary as shown in Fig. 3, and the underground temperature is lower than the conventional one.
It is possible to raise the temperature above 6°C to 19°C to 22°C. Therefore, even in places like Nagano and Hokuriku regions where the outside temperature is low, the sunshine hours are short, or there is continuous bad weather, the temperature inside the greenhouse, which could only be maintained with an 8V culm, can be maintained without using a heater. Since it is also possible to make 12'C or less, it gives great hope to these 4[lJ farmers. The driving force behind this effect is the effect of the newly invented heat storage material W. The principle is 11 when water is absorbed.

This is beard heat due to the latent heat of l/water absorption.

) The appropriate temperature and humidity are 20-25℃, R1 (60-80
%, but from March onwards, it has been overheated to over 35℃,
Fukagawa: It can also drop below 60'IA. However, by effectively utilizing the adsorption mechanism of the present invention, the high temperature can be suppressed, and all of these 7-stem environmental vessels can be solved (7 also the process can be -F
Tona-sho, the environment FjM adjustment is done smoothly. By the way, methods such as Hiro's have been used to suppress this high temperature, but the results were incomplete.

In other words, (1) a method using ventilation, (2) a method using narrow ventilation, and (3) a method using cooling...
According to the method of 1), the fgA degree in the greenhouse (1) is 5 to 7"C relative to the outside air temperature, that is, when the indoor air temperature is 35°C and the outside air temperature is 25°C, the fgA degree in the greenhouse (1) is 30°C. The limit is cooling to about ~32°C.Furthermore, according to method (2), the indoor temperature becomes excessive and the indoor temperature is also cooled to about -2~3°C, that is, the outside air temperature is 25'C, the indoor temperature is 35'C. time,
Cooling was limited to about 32 to 33°C, and high temperatures were not suppressed. (7) As shown in Fig. 7, the method of the present invention cleans and cools the outside air introduced for ventilation with a water-cooled suction cup (9), and passes the air with increased humidity through a multifaceted adsorption chamber (6) with an average RH of 30. 10 to 15℃ due to the latent heat of adsorption.
The air with increased vorticity is cooled by adsorption 1@cooler c24) set at the outlet as shown in Figure 7 and Table 2, and the enthalpy is lowered, and this low-humidity, low-enthalpy air is transferred into the greenhouse (1). Alternatively, the water is passed through the water droplets of the humidifying/cooling tower (21) set in the adsorption device, and due to the vigorous latent heat of vaporization of the dry air, the temperature of the outside air at this time is below the wet bulb temperature, for example, the temperature of the outside air is 18℃, Greenhouse (1)
When the internal temperature is 35℃, this method allows the outside air to be lowered to 15-17℃ as shown in Figure 7 and No. 2. So Aru.

In addition, the acupuncture water is not disposed of, but is cooled by a cooling tower (wings) installed outside the river, and then used for circulation. ;
Compared to this, water consumption can be significantly reduced. In addition, the cooling power of the water in the external Gooling Tower (c23) is slightly higher than the wet bulb polarity of the outside air, that is, when the outside air wet bulb vortex m'' is 15 to 17 degrees Celsius, as shown in Figure 7 and Figure 2, 17 It is possible to cool the sea bream to ~191C.Furthermore, the airborne dust at this time is adjusted to the optimum environment using a humidistat.Furthermore, with the conventional cooling method for thin tuna, the ll in the greenhouse (1) tends to become high. ,
The latent heat of oxidation can be utilized in this Shiki invention C.
In addition, since air at a low temperature is added regardless of the humidity inside the greenhouse (1), a high degree of heat of vaporization can be utilized, resulting in a large utilization effect.

That's right. As shown in these figures, synthetic zeolite and alumina gel are suitable for the present invention, and experimental results have shown that they are stronger than other adsorbents. That is, it has a strong adsorption power to the adsorbed substances related to the present invention, such as moisture, Co, %NJs formaldehyde, and sludge with low partial pressure, such as nitrogen-based disinfectants. In addition, the adsorption ability for bacteria and molds is due to adsorption and dehydration effects related to water activity (Aw), and the AWo of bacteria and molds is 9 to 0.78.
The adsorbent is Awo, 05-02, and the adsorbed harmful bacteria become dehydrated and die. In addition, the harmful fungi that remain alive after being adsorbed are completely sterilized by the temperature of 120 to 200° C. during the heating process of the St absorbing agent, which is carried out in a regular cycle. Adsorbents like activated carbon, which are characterized by their ability to adsorb gases at partial pressures, absorb moisture and CO.

Activated carbon is not suitable for adsorbing homopolar gases, but it is more powerful for adsorbing and removing drug gases and malodorous gases. 1 of each adsorbent
The feature of the device of the present invention is that it takes advantage of time and uses adsorbents in a mixed state.
This is why it is called ``agent''.

The results of an experiment using No. 2953 [High-load j-do□: type..., high-pressure burner with combustion furnace] and comparison with electric power are as follows.

To explain the 9fi+ effect of the first invention, in the first invention, there is a multi-purpose adsorption layer filled with an adsorbent (alumina gel, 7 lyca gel, activated carbon, etc.) that can be easily heated and regenerated for a long time. to pass air inside or outside the greenhouse,
As shown in Figures 1 and 2, CO2 and moisture are adsorbed and removed, and adsorbed substances such as moisture and CO1 are released into the greenhouse as needed. Toshit
21. At night, the greenhouse was heated to a small size,
00. By increasing the concentration of CO during the day when sufficient CO2 is required, it is possible to create a slender environment that is close to natural in terms of the environment, or a wet environment of 741 or more. Finally, it prevents dew condensation on the leaves, stems, fruits, etc. of crops being cultivated in Saida Reiu, prevents the decline in respiratory function, and eliminates epidemics caused by the activation of bacteria and fungi. It has the following advantages.

To explain the effect of the invention marked 2, in the case of the present invention,
ttv, -F A heat storage blowing pipe has many holes or outlets, and a layer of natural colloid, chabazite, etc. is formed on the outside of the pipe, or if the pipe is not used, it is made of lumpy A layer of absorbent material is provided, warm air to be stored is introduced into the layer, and the absorbent material's strong water absorption power is used to absorb condensed water and groundwater that occur during heat storage, resulting in underground heat storage (1 to 4 seconds). Z
It has the advantage of preventing water from entering the wind pipe, improving the flow of air within the heat storage layer, and improving the heat storage effect and waste heat exchange effect.

To explain the effect of the third invention, in the present invention, the moisture and harmful substances η in the greenhouse are removed by one layer of rJN through the multipurpose adsorption layer used in the first invention, and the heat absorption causes the temperature to rise. Cool the air with a water cooler7.
Fake the enthalpy of 1g9 qi, lower the temperature,
By passing the air in the lowering/Talby through the water droplets in the heat exchanger or the V-shaped container, the temperature of the air was lowered by the intense heat of vaporization of the low-humidity air, so the temperature could be brought to market. In addition, the amount of groundwater used in this cracking process is enormous, and it is impossible to use it in places where there is little groundwater.Moreover, the humidity of the indoor air is too high, making it impossible to utilize the heat of vaporization. In contrast, the present invention utilizes only the temperature of groundwater, that is, sensible heat, but the present invention brings ultra-low-humidity air, which has been dehumidified by a suction layer, into contact with water droplets, regardless of the humidity inside the room. Humidity is further reduced, and since cooling is circulated through a cooling tower installed outside, the amount of hydroxyl consumed is very small. Examples of operation of the apparatus of the present invention are shown in Table 2 and FIG.

Regarding the effect of the fourth invention, harmful fungi are collected and adsorbed by the multifaceted adsorption layer used in the first invention, and the adsorbed blind fungi are removed by the conventional microfilter.
It's better to filter it! ! The mechanism is completely different from filtration, as the air containing harmful bacteria passes through a granular adsorbent layer filled with several tens of centimeters in thickness or more, with resistance, and is completely removed by adsorption. , the harmful bacteria after adsorption are killed by the original action of the adsorbent, and more than 1,
. Adsorption ratio within IJIPi (7) ``1.1 to 71 to 85 or less, so harmful bacteria will naturally die in this environment, and the adsorbent will be regenerated by heating above 200 degrees Celsius, reducing the amount of adsorbed harmful bacteria. Bacteria are burned to death here, and sterilization is accomplished through the above three steps.
