How to Design a Greenhouse for Hot and Dry Climate Regions

Hot and dry climate regions require special attention in greenhouse design. High solar radiation, low humidity and strong daytime heat can increase crop stress, water demand and cooling cost. The first design point is shading. External shading, internal shading or shade net can reduce excessive sunlight and lower crop temperature. The correct shading rate depends on crop type, season and local sunlight intensity. The second point is ventilation. Roof vents, side vents and roll-up sidewalls can help release hot air. For multi-span greenhouse projects, roof ventilation and side ventilation should be designed together to improve airflow. Cooling pad and exhaust fan systems are often useful in dry climates. When outside humidity is low, evaporative cooling can reduce incoming air temperature. The cooling wall size, fan capacity, water pump and water quality should be calculated according to greenhouse size. Fogging systems can also support humidity and cooling, especially for nurseries and flowers. However, filtration and control are important to avoid nozzle clogging and uneven humidity. Irrigation and fertigation must be planned carefully. Drip irrigation, filters, pressure regulators and fertilizer injection systems help deliver water and nutrients accurately in hot conditions. For hot climate greenhouse design, provide these details to your supplier: - Maximum summer temperature - Relative humidity range - Crop type - Greenhouse size and orientation - Water source and electricity supply - Desired cooling and shading level NSR Greenhouse can provide greenhouse structure, shading, ventilation, cooling, irrigation and control systems for hot and dry climate farm projects.
