How to ventilate and cool down the flower greenhouse? The effect of negative pressure fan for ventilation and cooling of flower greenhouse. Greenhouse ventilation and cooling 1, the role of negative pressure fan: in summer, the negative pressure fan can ventilate the hot air through ventilation and introduce cool fresh air. The use of negative pressure fans can reduce the internal temperature of the greenhouse and create a suitable growth environment. This helps to maintain good air quality and provides enough oxygen and carbon dioxide for flowers to grow healthily.
2. The function of the water curtain: the negative pressure fan is mainly responsible for ventilation and cooling, while the water curtain further reduces the temperature and increases the humidity through evaporation and heat absorption. Set the water curtain in front of the negative pressure fan, when fresh air passes through the water curtain, the moisture will evaporate and absorb the heat, which can help reduce the temperature of the flower greenhouse.
3. Design of ventilation system: In order to ensure the ventilation effect and cooling effect of the flower greenhouse, it is necessary to use it together with a negative pressure fan, and a negative pressure fan is installed on one side of the greenhouse, and a water curtain is installed on the other side to ensure that the sealing of the greenhouse is good and to avoid air leakage. The number of water curtains and negative pressure fans should be calculated according to the area and height of the greenhouse to ensure the effect of ventilation and cooling.
The ventilation and cooling of flower greenhouses is an important part of crops. Improving the rational use of negative pressure fans and water curtain ventilation and cooling equipment can create a suitable growth environment and ensure the growth rate and quality of flowers.
