With the improvement of modern science and technology, the cultivation of fungi, flowers, vegetables, livestock and poultry is becoming more and more standardized and large-scale. The degree of advantages and disadvantages of indoor environmental factors has a direct impact on the growth and economic benefits of plants, livestock and poultry. This includes illumination, temperature, humidity, carbon dioxide concentration, etc., among which in addition to illumination conditions, other factors can be achieved through manual control. According to the different environmental conditions required by plants or animals in different growth stages, we can artificially adjust and control these conditions to favor the growth of plants or animals. The breeding air conditioning fresh air energy saving system produced by our company can take into account all kinds of parameters and energy utilization, so as to save energy to the greatest extent for enterprises and provide the best environment for the growth of organisms and animals.The air conditioning systemThe selection of air conditioning system can be based on the local climate characteristics and natural conditions of users, choose different types of refrigeration and heating, fully compare the cost performance and operation cost, reasonable and scientific allocation of resources can not only reduce the cost of input, but also can improve the output ratio and increase economic benefits.
The ventilation systemEr bestaan vele manieren van ventilatie; vooral het verse-lucht-systeem met warmte- en koude‑ (latente‑warmte‑)terugwinning is het beste. Dit verse‑lucht‑systeem heeft de volgende kenmerken: 1. Wanneer het verse‑lucht‑systeem wordt ingeschakeld, kan het in de machine ingebouwde warmtewisselingsapparaat de koelcapaciteit of warmte in de afvoerlucht effectief terugwinnen en de verse lucht vooraf koelen of verwarmen, wat een opmerkelijk energiebesparend effect oplevert. Over het algemeen kunnen 50–70% van de koude en warmte worden teruggewonnen en kan 35–55% van de vochtige terugwinning worden bereikt.
2. It is faster to adjust the concentration of carbon dioxide in the room, and the unit has the functions of simultaneously supplying and exhausting air, which can discharge carbon dioxide, ammonia and other harmful gases in the breeding space more quickly while transporting fresh air.
3. The configuration of temperature, humidity and CARBON dioxide sensors can realize the automatic operation control of the breeding place.
Energy-saving effect analysis
Taking vegetable production base as an example, the air conditioning system adopts water-cooled screw unit for centralized cooling, and each room is independently adjusted through PLC control system, which can better control various values to meet the requirements of different growth stages.
Example: Vegetable production space: length * width * height =40*8*7=2240m3
The principle of fresh air heat transfer and the calculation of heat transfer efficiency and heat transfer are shown in the figure below:
Model selection calculation data
Het is duidelijk dat elk apparaat 57 kW aan warmte terugwint; de totale warmte die door de vier apparaten wordt teruggewonnen bedraagt dus 57 × 4 = 228 kW. De efficiëntie van de warmteterugwinning bedraagt 60%, en de efficiëntie van de vochtige terugwinning 37,1%.
De gehele groeicyclus wordt berekend op basis van 1/3 van de opstarttijd, en de belasting van de verse lucht bedraagt 133 kW. De terugwinnings‑efficiëntie wordt geschat op 60%, waardoor de warmte die uit de verse‑lucht‑wisselaar wordt teruggewonnen 80 kW bedraagt.
Na aftrek van het stroomverbruik van de ventilator en de energieverliezen van de omhullende constructie van de champignonkas, kan de uiteindelijke energiebesparing meer dan 35% bedragen.
Through the above case analysis, it can be seen that large-scale breeding mode supporting specialized equipment can create the greatest economic benefits for users.
