Temperature is one of the most basic and important environmental conditions for crops. The temperature directly affects the normal growth and development of crops.
Most area of our country belongs to the continental monsoon climate, the temperature range is relatively large. Such climatic conditions are unfavorable to the growth of crops in warm rooms. Therefore, solving the problem of temperature rising and cooling in greenhouse is one of the key factors to ensure the normal growth of crops.
First of all, in general cooling by natural ventilation, mechanical ventilation, mechanical refrigeration, evaporative cooling, internal shading, shading, curtain and fan cooling measures.
Shandong Jienuo temperature control equipment R & D Manufacturing Co. Ltd focus on all kinds of temperature control equipment, all kinds of products have achieved good results in the actual implementation of the project, especially in the greenhouse temperature control has accumulated rich experience in the field.
(1) fan temperature curtain cooling system;
Action principle
When the outdoor hot air is sucked in through the wet curtain filled with water, the moisture on the wet curtain absorbs heat and evaporates, thereby reducing the air temperature entering the greenhouse. Usually, a wet curtain wall consists of a wet curtain, a wet curtain, a water distribution system, a water pump and a water tank. It is built continuously along a side wall of the greenhouse, while the fan is centrally arranged on the gable of the other side of the greenhouse. The wet curtain must be kept moist to ensure the evaporative cooling process, according to the size of the greenhouse and the region, selecting a proper fan installed in the wet curtain across the wall, make the air flow smoothly through the greenhouse ventilation cooling effect, achieve.
