Overview

Because the greenhouse has the function of light transmission and heating, the temperature in the greenhouse is much higher than the external environment when the flowers bloom in spring. This high temperature environment is not conducive to the growth of plants, so the greenhouse spray cooling system is required.

Product Details

　　Greenhouse spray cooling systemThe purpose of greenhouse planting is to accelerate the growth rate of plants. The greenhouse effect is very good for winter planting, but now that the weather is gradually warming up, it is a good time for outdoor plants to grow naturally. However, it is not conducive to the growth of crops grown in greenhouses.

Due to the inherent functions of light transmission and heating in greenhouses, the temperature inside the greenhouse is much higher than the external environment during the warm spring season, which is not conducive to plant growth. The specific manifestations are as follows:

1. High temperatures can cause a significant increase in evaporation within the greenhouse, leading to wilting and withering of seedlings and plants.

2. Poor flower bud differentiation occurs. Some fruits and vegetables may experience a decrease in female flowers and an increase in male flowers under high temperature conditions.

3. Causing flowers and fruits to fall. Excessive temperature can lead to a significant consumption of photosynthetic products in crops, resulting in insufficient nutrient supply for flower bud differentiation and young fruits, exacerbating flower and fruit drop, and reducing crop yield.

4. Affects the normal formation of pigments. Practice has proven that the optimal temperature for tomato growth is 20-30 degrees Celsius. Within this range, when the temperature is high, coloring is fast and the color is good. Coloring slows down when the temperature exceeds 30 degrees. When the temperature reaches 35 degrees, it becomes difficult to form lycopene. Even if the fruit is ripe, its color is not good, which affects its commercial value.

　　1、 Equipment parameters

2、 Working principle

　　Greenhouse spray cooling equipmentIt is to use a high-pressure host to pressurize ordinary water through a high-pressure system to above 4.5Mpa, and then use a high-pressure pipeline to impact the high-pressure water through a gemstone collision needle nozzle, changing the velocity distribution of the jet section. This breaks down and atomizes large water droplets into small particles. Under the action of aerodynamic force, small water droplets are further broken and atomized into countless "fine mist" with a diameter of 5-15 microns. These atomized particles evaporate and absorb a large amount of thermal energy from the air, thereby reducing the indoor air temperature.

　　3、 Organizational Structure

1. Water treatment equipment: Water sources in different regions have varying degrees of impurities and water quality. In order to ensure atomization effect and avoid nozzle blockage, it is usually necessary to filter and treat the water source; The water treatment equipment mainly includes ordinary filters (PP cotton, filtration accuracy of 5 microns), water softeners (mainly for removing calcium and magnesium ions from water), and ultrafiltration membrane filters (filtration accuracy of 0.01 microns);

2. High voltage host: mainly includes waterproof cabinets, control devices (time control, other control methods), protection devices (water shortage protection, leakage protection, overvoltage protection and other protection methods), motors, water pumps, electrical components, etc;

3. Atomization device: mainly includes high-pressure pipelines (conveying pressurized water), joints (connecting pipelines and nozzles), atomization nozzles and other accessories;

　　4、 Core functions

1. Voltage protection function: overvoltage protection, overload protection, overcurrent protection;

2. Water shortage protection function: After water shortage, the equipment will automatically stop running, and at the same time, the equipment will sound and light an alarm to indicate equipment failure. After replenishing water, it will automatically extend the startup time;

3. Automatic customization function: 16 sets of data can be set according to the date, and the device can be automatically controlled to turn on and off; You can set the start time and shutdown time each time, adjust the equipment running time according to the on-site effect, improve water resource utilization, control the equipment opening time reasonably, and achieve energy-saving function;

4. Automatic frequency conversion system: The equipment can automatically adjust the motor speed based on the pressure data transmitted by the pressure sensor; The service life of variable frequency motors is more than twice that of ordinary motors; Variable frequency motors are more energy-efficient; To prevent sudden pipeline rupture and other impact losses caused by excessive water pressure, while reducing pressure and motor speed, effectively reducing water pump pressure;

5. Fault alarm function: In case of water shortage or other faults, the equipment automatically provides sound and light alarm function.
