Overview

Greenhouse water mist cooling system. Due to the enclosed space, the respiration of plants and the accumulation of light in greenhouses may cause high environmental temperature and insufficient humidity, resulting in significant losses such as dehydration, dryness, and slow growth of plants during the planting process. In order to solve the problem of high temperature in greenhouses, cooling equipment must be installed in greenhouses.

Product Details

　　Greenhouse water mist cooling systemNowadays, large-scale planting technology has entered a mature stage and is widely used in agricultural cultivation such as greenhouses, flower nurseries, edible mushroom cultivation, and greenhouse cultivation. The greenhouse effect provides us with great convenience, and off-season vegetables have entered people's daily lives.

Nowadays, with the warm spring season and blooming flowers, it is generally a good time for crop growth. However, experienced greenhouse growers know that due to the enclosed space, the respiration of plants and the concentration of light in greenhouses may cause high environmental temperatures and insufficient humidity, resulting in significant losses such as dehydration, dryness, and slow growth of plants during the planting process. In order to solve the problem of high temperature in greenhouses, cooling equipment must be installed in greenhouses.

Common greenhouse cooling methods include sunshade cooling, wet curtain cooling and spray system cooling.

1. Sunshade cooling is the process of blocking excess sunlight outside the greenhouse to create shade and protect the crops inside. It keeps the temperature inside the greenhouse at a suitable level, effectively blocking direct sunlight from the crops. This cooling method requires external shading materials to be sturdy, durable, have low elasticity, and anti-aging, resulting in higher costs.

2. Wet curtain cooling refers to the process in which high-temperature external air passes through a water immersed wet curtain, humidifies and cools down, and forms cold air. The cold air absorbs waste heat through a controlled room and is then discharged outdoors. It mainly uses the evaporation of water to cool down, because the evaporation of water needs to absorb heat, which can take away some of the heat inside the greenhouse. At the same time, it starts the fan to extract the hot air flow inside the greenhouse for cooling.

3Spray system cooling，Greenhouse water mist cooling systemThe cooling method is similar to wet curtain cooling, which uses water evaporation to absorb heat from the air to achieve the cooling effect. The difference is that the spray dust suppression system changes water into 1-15 μ m atomized particles. The atomized particles are extremely small and easy to diffuse in the air, so as to absorb more heat, accelerate the evaporation speed, and the cooling effect is more obvious than the wet curtain.
