Chapter 206 Greenhouse Design

Since Aite has thought about it, he continued: "The top ventilation I designed adopts the ridge butterfly staggered window opening method, and uses the high-end brand with limit geared motor and rack and pinion mechanism, and the design ventilation window ratio is about 24%. The side ventilation is on the east and west sides of the greenhouse, about 0.6m above the ground, and the plastic steel hollow white float glass sliding window is installed, and the window height is 1.2 meters. ”

"There is also an insect-proof net, all windows should be equipped with 25-mesh insect-proof nets, and wet curtains should be equipped with 25-mesh insect-proof nets, so that the isolation performance is good, and it is easy to replace. However, due to the structure of the greenhouse, the characteristics of the heating equipment and the cooling equipment, there will be differences in temperature, humidity and carbon dioxide concentration between different areas of the greenhouse interior. ”

"Therefore, in order to evenly distribute the temperature, humidity and carbon dioxide concentration of the air in the growing area, the air must be artificially moved by using fans. 21 circulating fans are arranged in an orderly manner in the greenhouse, which not only ensures the continuity of air flow, but also prevents the air flow from blowing directly to the crops. ”

"In addition, all gutters should be fitted with aluminium condensate recovery tanks with brackets and end outlets with PE hoses. The condensate is discharged to the outside through the water pipes to reduce the humidity in the greenhouse, which is conducive to the growth of crops and prevents pests and diseases. The condensate from the roof enters the condensate recovery tank through the condensate guide plates installed on the rafters. ”

Jesse Chou felt as if he was very powerful when he heard it, but this time he understood it, and these things were much simpler when they were separated. If you think about it, you can understand what it means! "Very well, Aite, you go on."

Aite took a sip of coffee, then fiddled with the computer, and then pointed out to Jessie Chou to see, "The following is the more important, the inner sunshade insulation system." It can improve the ecological environment of the greenhouse in many ways. ”

"In the hot summer, its shade curtain can block part of the sunlight and diffuse the sunlight into the room, evenly irradiate the crops, protect the crops from strong light burns, and at the same time reduce the greenhouse temperature by 4-6 °C; By choosing different curtains, different shading rates can be formed to meet the needs of different crops for sunlight. ”

"In winter, the night internal sun insulation system can also effectively prevent infrared rays from escaping, reduce the radiant heat loss on the ground, and reduce heating energy consumption. The curtain adopts a dual-purpose screen for sunshade and thermal insulation, with a shading rate of about 70% and an energy-saving rate of about 57%, which can greatly reduce the operating cost of the greenhouse. Aite flipped a few pictures up and down so that Jesse Chou could understand better.

"Well, that's a good design!" Jessie Chou said after reading it.

"Then there's the external shading system, which in the summer keeps the excess sunlight out of the air, creating shade and protecting the crops from strong light burns and creating the right growing conditions for the crops. The shade screen can meet the indoor requirements, control the humidity and maintain the appropriate heat level, so that the sunlight can diffuse into the greenhouse planting area, and maintain the best crop growing environment," said Aite, pointing to the picture.

"There is also this fan/wet curtain cooling system, which uses the principle of evaporative cooling of water to achieve the purpose of cooling. At the heart of the cooling system is a wet curtain that allows water to evaporate, which is made of corrugated fiber paper, which is corrosion-resistant and has a long service life due to the addition of special chemical components to the raw material. ”

"In addition, the special water transfer pad ensures that the water evenly wets the entire cooling pad wall. When the air penetrates the wet pad medium, the water vapor on the surface of the wet medium is exchanged to convert the sensible heat of the air into the latent heat of vaporization, so as to achieve humidification and cooling of the air. ”

"I'm going to install the pads at the north end of the greenhouse and the fans at the south end of the greenhouse. When it is necessary to cool down, the fan is started through the command of the control system to forcibly pump out the indoor air to cause negative pressure. ”

At the same time, the water pump hits the water on the opposite wet curtain wall, and the outside air is sucked into the room under negative pressure. It passes through the gaps in the pad at a certain speed, causing the water to evaporate, cool down, and cold air to flow through the greenhouse. After absorbing the indoor heat, it is discharged through the fan, so as to achieve the purpose of circulating cooling. ”

"Wow, that's a great design." Even Atwood couldn't help but say, then turned to look at old Aite and said, "Old man, it seems that your son is much better than you, I think you can almost consider retiring!" ”

"Huh...... I'm really getting ready to retire recently, and it's time to enjoy my life. I don't want to be reluctant a few years ago, but now when I see Aite, sometimes I really feel old! Old Aite said a little helplessly.

"Old man, you're already old, that's a fact! Hehe......" Atwood patted him on the shoulder and said to him!

At this time, where can Jesse Chou and Xiao Aite intervene in the two old people's emotions of remembrance. So the two of them are still talking, and Jesse Chou hopes to know more about it. And Xiao Aite also hopes to explain himself and this system to others, and if this person appreciates his words, he will be very happy!

So sometimes, suddenly happiness and happiness are very simple, and it depends on yourself whether you are satisfied.

"Mr. Zhou, the most important thing in my system is this computer control system." Little Aite pointed to something and said to Jessie Chou.

"Oh, that's what you're talking about, that's what I'm talking about smart devices, right?" Jessie Chou asked.

"Well, it's pretty much the same as that! It uses a variety of sensors to collect parameters related to the greenhouse environment (such as air temperature, humidity, light, etc.). When the collection comes in and according to certain rules, control the various executive drive equipment (such as skylights, fans, wet curtains, etc.) in the greenhouse. ”

Then Aite moved his glasses and smiled at Zhou Jesse: "In this way, we can achieve the purpose of manually controlling the greenhouse environment, and have the functions and effects of a fully automated and intelligent computer system!" ”

"Wow, go on!" Jessie Zhou sighed at Lao Mei's technology, it is indeed a hand. This money is going to be spent, and I won't feel wronged!

"My control concept is perfect and advanced, and the system has the control concept of the Argus control system in Canada. Combined with the research results of facility agriculture from various universities in California, we continue to integrate the control needs of user feedback. ”

"It has formed a perfect advanced control concept, and the control equipment is also extremely rich, which can control the skylight, external sunshade, internal sunshade, internal insulation curtain, fan, wet curtain, wet curtain outward window, circulation fan, fill light, irrigation pump, irrigation felling, fertilization felling, etc."

"And the system detection ability is very strong, the control system can simultaneously detect outdoor temperature, humidity, wind speed, wind direction, light radiation, rain and snow signal, rainfall, indoor multi-point humidity, multi-point light intensity, carbon dioxide concentration, soil temperature and humidity, nutrient solution PH value, nutrient solution Ec value, plumbing water temperature, etc."

"Four periods a day, independent target temperature and humidity design. It will meet the needs of plants to grow at different times throughout the day, which is a very user-friendly operation. Our controller uses a large LCD screen that can display 15 lines at the same time, which is extremely rich in display content. ”

"It can also make a sci-fi look, and the '3D animation monitoring interface' will make the effect extremely realistic. It's definitely at the level of the top of the United States, so if you have to install it, I'm sure you're going to love it, because it's so convenient! Little Aite said excitedly.

Jessie Chou felt that he seemed to be attached to someone at this time, and he had the taste of an orator. How to say it, it's very demagogic, Jessie Chou has to say that he is already moved, so he almost makes a decision now.
