An Agricutual Air Conditioner is not a conventional comfort air conditioner used for people. It is a special environmental control system designed for crops, fungi, grain, seeds, animals and agricultural storage conditions. In modern agriculture, temperature, humidity, CO₂ concentration, airflow, fresh air volume, pressure balance, filtration level and operating schedule directly affect yield, quality, disease prevention, storage safety and operating cost. HISURP agricultural cooling products are developed to help growers and grain storage operators move from weather-dependent production to stable, precise and intelligent environmental control.

Agricultural Air Conditioner is also known as farm climate control system, plant cultivation air conditioner, granary air conditioner and grain cooler.

What is an Agricutual Air Conditioner?

An Agricutual Air Conditioner is a dedicated air conditioning and environmental control solution for agricultural production and storage. It can include plant cultivation air conditioners, mushroom room air handling units, air cooled heat exchangers, granary air conditioners, low-temperature grain storage air conditioners and grain coolers. These products serve different agricultural scenarios, but they share one core purpose: creating a stable and controllable environment for biological growth or safe storage.

For mushroom cultivation, the system controls temperature, humidity, fresh air, CO₂ concentration, filtration and different growing stages. For greenhouses and horticulture, it supports air circulation, cooling, heating and humidity regulation. For granaries, it protects stored grain by reducing temperature, maintaining moisture, resisting phosphine corrosion and supporting green storage. For grain cooling, it provides conditioned air with controlled temperature and humidity to cool the entire grain pile and delay quality deterioration.

Plant cultivation and mushroom room climate control

The HISURP plant cultivation air conditioner is designed for edible fungi and controlled agricultural production. It is suitable for king oyster mushroom, shimeji mushroom, maitake, enoki mushroom, black fungus, button mushroom, straw mushroom, oyster mushroom, shiitake mushroom, termite mushroom, flower cultivation and vegetable greenhouse planting.

Unlike a comfort air conditioner, a plant cultivation unit controls the growth environment around the crop. It can integrate ventilation, humidity control, temperature control, fresh air, CO₂ concentration, air purification, cultivation stage timing and process control.

Key advantages

High-precision temperature control

Temperature accuracy can reach approximately **±0.5°C to ±1°C**, helping avoid crop stress caused by temperature fluctuation.

Independent humidity regulation

The unit can perform cooling dehumidification, heating, humidification or combined control according to crop requirements.

CO₂ and fresh air control  

Mushroom growth is sensitive to CO₂ concentration. The system can regulate fresh air and CO₂ according to different cultivation phases.

Multi-stage process control

The system can support 8 product categories and 6 growth stages for each category. Parameters for every stage can be set independently, including air temperature, material temperature, humidity, CO₂ concentration and duration.

Variable frequency linear control

The compressor can operate across a wide frequency range, with smooth stepless adjustment. Combined with adaptive control technology, the system can match real load changes more accurately and reduce unnecessary energy consumption.

Microcomputer intelligent control  

The unit supports intelligent control, fault diagnosis and alarm functions. Standard wired controllers, large LCD text display, centralized group control interface, remote dry contact interface, fire alarm input, fault interface and optional RS485 communication port can be configured.

Air cooled heat exchanger for greenhouse and breeding applications

HISURP air cooled heat exchangers are suitable for flower horticulture, greenhouses, vegetable seedling cultivation, livestock breeding, aquaculture and workshop temperature control. The unit can use chilled water for cooling or hot water for heating, making it practical for agricultural facilities that already have a water-side energy system.

Product features

- Anti-corrosion structure:fan fixing plates and drain pans use galvanized sheet with powder coating for better corrosion resistance.  

- High heat exchange efficiency: copper tube with hydrophilic corrugated aluminum fin structure and mechanical tube expansion improve heat transfer.  

- Low noise operation: options include external rotor axial fans, EC axial fans and centrifugal fans depending on airflow and noise requirements.  

- Cooling and heating common use: the unit can connect to chilled water or hot water.  

- Flexible forms: direct blowing type, ducted type, exposed type and exposed ducted type can be selected.

Installation should be performed by trained professionals. The unit must be fixed firmly and kept level. Flexible pipe connection is recommended for water inlet and outlet, and torque should not exceed 205.6 Nm to avoid twisting and leakage. Before wiring, voltage, frequency and phase should be checked, with recommended voltage deviation within 10% of the rated voltage.

Granary air conditioner for low-temperature grain storage

HISURP granary air conditioners are designed for grain warehouse temperature control. They solve three major problems that ordinary air conditioners face in grain storage: phosphine corrosion during fumigation, dust impact during grain loading and unloading, and moisture loss caused by excessive dehumidification.

Core benefits

**Anti-corrosion design**  

Special anti-corrosion coatings reduce phosphine corrosion. Motors are sealed, lead wire areas are resin-sealed, and control circuits can be placed outdoors where corrosive gases are less likely to contact them. Temperature sensors can be coated with high anti-corrosion material.

**High sensible heat ratio**  

The design uses large airflow and large heat exchangers. Test data indicates that approximately **90%** of the cooling capacity can be directly used for air temperature reduction, while ordinary AC units may only reach about **65–70%** sensible heat ratio. This helps reduce grain moisture loss while lowering warehouse temperature.

**Long-distance air supply**  

For a standard grain warehouse width of **24 meters**, HISURP granary air conditioners adopt guided jet outlet design. Effective air supply distance can reach around **16 meters**, and the limit distance can reach about **24 meters**, helping achieve uniform temperature distribution.

**Low-temperature storage**  

Low-temperature grain storage generally controls grain temperature at **10–15°C**. This suppresses grain respiration, insect activity and mold growth. Storage insects are active at **15–35°C**, with the most suitable reproduction temperature around **27–32°C**. When grain temperature drops below **17°C**, pests cannot develop quickly; at **8–15°C**, insect activity is greatly reduced.

**Controlled atmosphere storage compatibility**  

For airtight nitrogen storage, HISURP can provide controlled atmosphere granary air conditioners. The evaporator side can adopt a highly sealed structure. Under **500 Pa nitrogen pressure holding test**, the pressure attenuation rate within 24 hours can be **≤50%**, which ordinary air conditioners cannot achieve.

Grain cooler for green low-temperature storage

The HISURP grain cooler conditions ambient air through filtration, cooling and humidity adjustment, then sends air with suitable temperature and humidity into the warehouse. It is suitable for vertical silos, shallow round warehouses, flat warehouses and different types of grain and oilseed storage, including rice, wheat, corn and oil crops.

Grain cooler advantages

- Maintains grain quality and delays aging.  

- Reduces insect and microbial growth without chemical fumigation.  

- Helps preserve color, aroma, flavor and edible quality.  

- Reduces storage loss caused by respiration, pests, heating, mildew and grain turning.  

- Uses PLC intelligent control with automatic, manual, ventilation and timing modes.  

- Supports remote monitoring and long-term unattended operation.  

- Uses variable frequency fan control for automatic airflow adjustment.  

- Stainless steel structure improves outdoor corrosion resistance.  

- More than 80% of key control and refrigeration components can use internationally recognized brands depending on configuration.

The grain cooling process is clear: ambient air passes through filters, enters the evaporator for cooling, becomes cold and humid air, then passes through reheating and humidity adjustment. Finally, a variable-frequency centrifugal fan sends air with the set temperature and humidity into the warehouse. The PLC system automatically controls supply air conditions.
