Constant Temperature and Humidity Air Conditioning for Hydroponic Greenhouses Used in Vegetable Cultivation

In hydroponic greenhouses, constant temperature and humidity air conditioning plays a crucial role in vegetable growth:

Working Principle: The constant temperature and humidity air conditioning system controls temperature through refrigeration and heating systems, while regulating humidity via humidification and dehumidification functions. Cooling is typically achieved through cooling coils, while heating can be provided by electric heating elements or coil heating. Dehumidification may utilize condensation dehumidification or dedicated equipment like desiccant dehumidifiers, while humidification commonly employs electric heating or electrode humidification methods.

Key Functions

Precise Temperature Control: Automatically activates cooling or heating modes based on vegetable growth requirements, maintaining stable temperatures at set points to provide optimal growing conditions.

Precise Humidity Regulation: Maintains humidity within optimal ranges through humidification and dehumidification functions, preventing pest proliferation from excessive moisture or growth inhibition from insufficient humidity.

Optimized Air Quality: Equipped with high-efficiency filters to remove dust and bacteria while introducing fresh air via a ventilation system and expelling stale air. This ensures air circulation and prevents excessive carbon dioxide buildup.

Equipment Features

Energy Efficiency: Direct expansion constant temperature and humidity air conditioning units utilize a full DC inverter system. They precisely match output based on outdoor ambient temperature and indoor unit operation, achieving energy-saving results.

Smart Control: Many constant temperature and humidity air conditioners support remote monitoring and adjustment, allowing users to view environmental data and modify parameters in real-time via mobile devices or computers. For instance, the smart control system for containerized cultivation air conditioning units integrates 4G communication technology to enable real-time collection, intelligent adjustment, and remote monitoring of internal climate parameters.

High-Precision Control: Some units maintain temperature regulation within 10°C–28°C with ±1°C accuracy and humidity control between 40%–85% RH, meeting stringent temperature and humidity requirements across vegetable growth stages.

Practical Application Results: Implementing constant temperature and humidity air conditioning systems in hydroponic greenhouses significantly enhances vegetable yield and quality. According to relevant estimates, effective temperature and humidity control can increase crop yields by 20%-30%.
