Water curtain is a kind of equipment commonly used for greenhouse cooling, and its principle is to take away the heat in the air through water evaporation to achieve the effect of cooling. The following is the role of the water curtain in the cooling of the greenhouse, as well as some original explanations: Greenhouse cooling 1, evaporative cooling principle: The water curtain forms a water film by spraying water evenly on the curtain, and when the air passes through the water curtain, the water in the water film begins to evaporate. During evaporation, moisture absorbs heat from the air, causing the air temperature to drop. This is the famous principle of evaporative cooling, which absorbs the surrounding heat through the evaporation of water, so as to achieve the effect of cooling.
2. Humidity control: The water curtain can also regulate the indoor humidity while cooling down. Due to the evaporation of moisture, the humidity of the indoor air is increased, which is particularly suitable for cooling in dry climates.
3. Uniform cooling: The setting of the water curtain is usually relatively even, which can cover a large area of space. This ensures that the temperature in the greenhouse is relatively uniform throughout the greenhouse, and avoids the impact of excessive temperature differences on the plants.
4. Rapid cooling: The cooling speed of the water curtain is relatively fast. Once the water curtain system is activated, the indoor temperature will drop rapidly through the action of evaporative cooling, providing an effective means of responding quickly to hot weather.
5. Higher energy efficiency: Compared with some other cooling equipment, the energy efficiency of water curtains is higher. It does not require additional energy, only a water source and relatively low electrical energy to drive the pump, so it is relatively environmentally friendly in terms of energy use.
6. Suitable for different greenhouse types: The application of water curtain is more flexible and suitable for various types of greenhouse structures. Whether it's a plastic film greenhouse or a glass greenhouse, water curtains can be installed and adjusted relatively easily.
As a cooling device, the water curtain plays an important role in greenhouses, providing an effective and feasible way to make the indoor environment more suitable for plant growth through evaporative cooling and humidity control.
