Chapter 216 Greenhouse Design

Now that Aite has made up his mind, he continued: "The roof ventilation I designed adopts the roof ridge butterfly-shaped staggered window opening method, and uses a high-end brand with a limit deceleration motor and a rack and pinion mechanism. The designed ventilation window ratio is about 24%. The side ventilation is on the east and west sides of the greenhouse, at a height of about 0.6m above the ground, and the plastic steel hollow white float glass sliding windows are installed, and the height of the windows is 1.2m.”

"There is also the insect-proof net. All window openings must be equipped with 25-mesh insect-proof nets, and 25-mesh insect-proof nets should be installed at the wet curtains. This has good isolation performance and is easy to replace. However, due to the structure of the greenhouse and the heating equipment The characteristics of the cooling and cooling equipment will cause differences in temperature, humidity and carbon dioxide concentration between different areas inside the greenhouse."

"Therefore, in order to make the temperature, humidity and carbon dioxide concentration of the air in the crop growing area evenly distributed, it is necessary to use fans to artificially flow the air. 21 circulation fans are arranged in an orderly manner in the greenhouse to ensure the continuity of air flow and to ensure the continuity of air flow. Keep the air flow from blowing directly on the crop."

"Moreover, aluminum alloy condensed water recovery tanks must be installed under all gutters, and equipped with brackets and end water outlets with PE hoses. The condensed water is discharged to the outside through the water pipes to better reduce the humidity in the greenhouse. It is beneficial to the growth of crops and prevents diseases and pests. The condensed water condensed on the roof enters the condensed water recovery tank through the condensed water guide plate installed on the rafter bar.”

Zhou Jiexi felt like he was very powerful, but this time he understood it. It would be much easier to talk about these things separately. If you think about it carefully, you will understand what it means! "Very well, Aite, you can continue."

Aite took a sip of coffee, then fiddled with the computer, and then pointed to Zhou Jiexi, "The following is the more important one, the inner sunshade and heat preservation system. It can improve the ecological environment of the greenhouse in many ways."

"In the hot summer, its sunshade screen can block part of the sunlight, diffuse the sunlight into the room, irradiate the crops evenly, protect the crops from being burned by strong light, and at the same time reduce the temperature of the greenhouse by 4-6°C; by choosing different screens , can form different shading ratios to meet the sunlight needs of different crops.”

"The inner sun insulation system at night in winter can also effectively prevent infrared rays from escaping, reduce ground radiation heat loss, and reduce heating energy consumption. The curtain adopts dual-purpose sunshade and heat preservation curtains, 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 up and down a few pictures so that Zhou Jiexi could understand better.

"Well, this design is not bad!" Zhou Jiexi said after reading it.

"Then there is the external sunshade system. In summer, it can block excess sunlight outside, form a shade, protect crops from strong light burns, and create suitable growth conditions for crops. The sunshade screen can meet indoor requirements, control humidity and Maintain proper heat levels, diffuse sunlight into the greenhouse planting area, and maintain the best environment for crop growth," Aite said, pointing to the picture again.

"There is also this fan/wet curtain cooling system, which uses the principle of water evaporation to cool down. The core of the cooling system is the wet curtain that can evaporate water, which is made of corrugated fiber paper. Due to the special chemical composition added to the raw material, it is corrosion resistant and has a long service life.”

"In addition to the special water transfer wet curtain, it can ensure that the water is evenly wetted on the entire cooling wet curtain wall. When the air penetrates the wet curtain medium, the water vapor exchanged with the surface of the wet medium converts the sensible heat of the air into the latent heat of vaporization , to achieve humidification and cooling of the air.”

"I plan to install the wet curtain at the northern end of the greenhouse, and the fan at the southern end of the greenhouse. When cooling is required, the fan is activated through the command of the control system to forcibly draw out the air in the room, creating a negative pressure."

"At the same time, the water pump hits the water on the opposite wet curtain wall, and when the outdoor air is sucked into the room by negative pressure, it passes through the gap of the wet curtain at a certain speed, causing the water to evaporate and cool down, and the cold air flows through the greenhouse to absorb indoor heat. After that, it is discharged by the fan, so as to achieve the purpose of cooling cycle.”

"Wow, this design is great." Even Atwood couldn't help but say at this moment, and then turned his head to look at Old Ait and said, "Old man, it seems that your son is much better than you, I think you are almost the same Consider retiring!"

"Hehe... I'm really planning to retire recently, and it's time to enjoy life. I don't want to be reluctant a few years ago, but now I see Aite, sometimes I really feel old!" The old man Ait said a little helplessly.

"Old man, you are already old, this is a fact! Hehe..." Atwood patted his shoulder and said to him!

At this time, Zhou Jiexi and Xiao Aite, how can they intervene in the two old people, they clearly understand the mood of nostalgia. So the two were still talking, and Zhou Jiexi wanted to know more about it. And Xiao Aite also hopes to explain himself and this system to others. If this person appreciates him again, he will be very happy!

So sometimes, sudden happiness and happiness are very simple, it depends on whether you are satisfied or not.

"Mr. Zhou, the most important part of my system is the computer control system." Xiao Aite pointed to something and said to Zhou Jiexi.

"Oh, what you're talking about is the smart device, right?" Zhou Jiexi asked.

"Well, it's almost the same as that! It uses various 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, it controls various executive driving devices in the greenhouse. (such as skylights, fans, wet curtains, etc.)."

Then Aite moved his glasses, and smiled at Zhou Jiexi: "This way, we can achieve the goal of manually controlling the greenhouse environment, and have fully automated and intelligent computer system functions and effects!"

"Wow, keep talking!" Zhou Jiexi sighed for Laomei's technology, and he really has a hand. If the money is going to be spent, you won't feel wronged!

"My control concept is perfect and advanced, and the system has borrowed from the control concept of the Argus control system in Canada. It also combines the research results of facility agriculture in various universities in California, and continuously integrates the control needs of user feedback."

"A complete advanced control concept has been formed, and the control equipment is also extremely rich. It can simultaneously control skylights, external sunshades, internal sunshades, internal insulation curtains, fans, wet curtains, wet curtains turned outwards, circulation fans, fill lights, irrigation Water pumps, irrigation logs, fertilization logs, and more!"

"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 signals, rainfall, indoor multi-point humidity, multi-point light intensity, carbon dioxide concentration, soil temperature and humidity, and nutrient solution. PH value, Ec value of nutrient solution, water temperature, etc.!"

"4 times a day, design independent target temperature and humidity. It will meet the growth needs of plants at different times throughout the day. This is a very humanized operation. Our controller uses a large-screen LCD screen that can display 15 lines at the same time , the display content is extremely rich.”

"It can also be made into science fiction, and the '3D animation surveillance interface' screen will make the effect extremely realistic. This is definitely at the level of the high-level American, so you have to install it, I believe you will absolutely fall in love with this stuff, because it is so convenient!" Little Aite said extremely excitedly.

Zhou Jiexi felt that at this time, he seemed to be possessed by someone, and he looked like an orator. How should I put it, it is very deceptive, Zhou Jiexi has to say that he has already been moved, and he is almost ready to make a decision now.
