Challenges in Temperature and Humidity Regulation

Requirements for Temperature and Humidity

Different crops have strict and significantly different requirements for temperature and humidity at various growth stages. Traditional simple temperature control equipment is difficult to precisely meet diverse needs, which is likely to cause poor crop growth, reduced yields, or even death.

Changes in Temperature and Humidity

The agricultural production environment is greatly affected by the natural climate. Frequent fluctuations in temperature and humidity are brought about by the temperature difference between day and night and the change of seasons. During the day, with strong solar radiation, the temperature inside the greenhouse or shed may rise rapidly to above 40°C. At night, without effective thermal insulation, the temperature will drop sharply. The high-humidity environment is also prone to the breeding of diseases. Common ventilation and cooling methods cannot respond in a timely manner, making it difficult to maintain a stable environment for crop growth.
Air Quality Issues

Air Purification

In agricultural facilities, especially in enclosed or semi-enclosed greenhouses, the air circulation is poor, and problems such as insufficient carbon dioxide and excessive harmful gases are likely to accumulate. Crops consume a large amount of carbon dioxide during photosynthesis. If it is not replenished in a timely manner, it will limit the photosynthetic efficiency and affect growth. At the same time, the decomposition of fertilizers, the operation of fuel equipment, etc. will produce harmful gases such as ammonia and sulfur dioxide. When accumulated to a certain concentration, it will damage the leaves and roots of crops and reduce their stress resistance.

Air Pollution

During the process of preventing and controlling diseases and pests, if the harmful chemical substances remaining from pesticide spraying cannot be effectively discharged, they will not only pollute the air but may also be absorbed by crops, endangering the quality and safety of agricultural products and threatening the health of consumers.
The Contradiction between Energy Conservation and Cost

Profit Control

As the scale of agricultural production is expanding day by day, the operation time of environmental control equipment such as temperature control and ventilation is long and the energy consumption is high. Traditional air conditioners or heating systems have low energy efficiency under partial load conditions. For example, when only a small amount of additional heat is needed to maintain the temperature of the greenhouse at night in winter, turning on all conventional electric heating equipment will cause a large amount of electricity waste, increasing the production costs of farmers and squeezing the profit margin.

Cost Control

The costs of equipment purchase, installation, and maintenance are also a heavy burden for agricultural operators. Agricultural production has a strong seasonality. If the equipment is not properly maintained during the idle period, it is likely to be damaged. If the maintenance is not timely during the peak season, it will affect production. Frequent replacement of parts and hiring of professional personnel for maintenance will lead to a continuous increase in operating costs.
Equipment Reliability and Durability Issues

Durability

Agricultural production environments are complex and harsh, with high temperatures, high humidity, dust, and corrosive gases (such as fertilizer volatiles) coexisting, which strongly corrode the casings and internal components of air conditioning and other control equipment, shortening their service life.

Reliability

Agricultural facilities often face threats from natural disasters such as strong winds, heavy rain, and snowstorms. Equipment needs to have certain disaster resistance capabilities. If equipment fails at critical moments and cannot maintain a suitable environment, it will lead to large-scale crop damage, bringing devastating blows to farmers.

Solution Overview

Intelligent and Precise Temperature and Humidity Control System
Using IoT technology, high-precision temperature and humidity sensors are deployed at multiple points within agricultural facilities to collect environmental data in real-time and transmit it to an intelligent control cabinet. The control cabinet, based on preset crop growth model algorithms, automatically drives air conditioning units, humidifiers, dehumidifiers, and other equipment to operate precisely. To address large diurnal and seasonal temperature differences, heat/cold storage technology is employed. During high-temperature periods in summer, cold storage is driven by low nighttime electricity prices for cooling during the day, effectively balancing diurnal and seasonal temperature variations and reducing energy consumption.
Comprehensive Air Quality Management Solution
A carbon dioxide concentration sensor is installed and linked with the ventilation system. When the carbon dioxide concentration is lower than the threshold required by the crops, the fresh air valve is automatically opened to introduce outdoor air for supplementation. An air purification device is used, which includes primary and medium-efficiency filters to remove dust and impurities, an activated carbon adsorption layer to purify harmful gases such as ammonia and sulfur dioxide, and an ultraviolet germicidal lamp to kill germs and insect eggs, reducing the risk of diseases and pests and ensuring the quality of agricultural products and the health of the growth environment.
Strategies for Energy Conservation and Efficiency Improvement
Efficient and energy-saving refrigeration and heating equipment are selected. Combined with the intelligent control system, the output power of the equipment is precisely matched with the actual needs of agriculture to avoid excessive energy supply.
Measures for Ensuring High-reliability Equipment
The equipment shell is made of corrosion-resistant materials, and the internal key components such as heat exchangers and fans are treated with special coatings to enhance their corrosion resistance and adapt to the harsh agricultural environment. The structural design of the equipment is optimized to enhance its wind resistance and compressive capacity. Roof-mounted air conditioning units, ventilation equipment, etc. are reinforced to ensure normal operation in extreme weather such as strong winds and blizzards. A remote monitoring and early warning system is established to monitor the operating status of the equipment in real time, prevent failures in advance, and reduce disaster losses.

Details of the Solution and Its Advantages

Optimization of Professional Agricultural Environment Solutions
During the project planning stage, optimize the solutions in advance for different projects to provide ideal environmental regulation effects.
Breakthrough in Core Energy-saving Technologies
The intelligent variable flow control technology dynamically adjusts the flow rate and head of the water pump according to the real-time environmental load and water temperature changes, reducing ineffective energy consumption. Compared with the traditional fixed flow system, it significantly reduces the energy consumption of the water pump, improves the overall stability of the system, and extends the service life of the equipment.
Super-strong Air Purification Ability
The multi-stage air filtration system is finely graded to meet the needs of different agricultural scenarios. In vegetable greenhouses with high dust levels, the primary filtration is strengthened. For areas with aseptic requirements for flower and seedling cultivation, the focus is on improving the precision of high-efficiency filtration to ensure a clean air environment at the class 10,000 or even class 1,000 level, reducing the risk of the spread of diseases and pests and increasing the survival rate of seedlings.
Ultimate Reliability Assurance System
Strictly following international quality management standards, from the screening of raw materials to the ex-factory of finished products, the equipment goes through multiple rigorous inspection processes to ensure that there are zero defects in the equipment.
