Specifications for the layout of cooling pads and fans in greenhouses

The cooling system is the main means of cooling the greenhouse in summer, but the installation of some unprofessional fan water curtains will lead to a decrease in cooling efficiency. Today, I will share with you the layout requirements in the greenhouse cooling system design specifications. 

1.The fan and the cooling pad should be arranged on the opposite side, the fan is arranged on the south side and the cooling pad is arranged on the north side. The distance between the fan and the cooling pad is 30 m~45 for the best effect, and the limit should not exceed 68 meters. 

2.The installation of the cooling pad should consider the influence of the dominant wind direction on the air intake in summer, and the influence of the installation position on lighting. 

3.The height of the cooling pad should not exceed 2.4 meters and should not be less than 0.6 meters. In the installation height of the wall of the multi-span greenhouse, the actual crop height and the requirements of planting equipment such as the seedbed should be considered. 

4.The design of the cooling pad air inlet should consider the convenience of closing in winter without removing the cooling pad. The currently commonly used electric cooling pad side window (divided into vertical lifting and outward opening), as well as the fixed card slots around the outside, install insulation film and insulation cotton. 

5.When the height of the cooling pad exceeds the height of the air inlet, the cooling pad should be at least 1/2 of the height difference away from the air inlet.

6.When the ventilators are arranged on the same wall, the distance between the ventilators should not exceed 7.6 meters. 

7.The distance between the exhaust port of the ventilator and nearby obstacles should not be less than 4 times the diameter of the ventilator. 

8. When the distance between the ventilator and the air inlet of the adjacent greenhouse cooling pad is less than 15 m, the exhaust airflow of the ventilator should not be directly facing the air inlet of the cooling pad.
