High pressure spray cooling equipment——review

Each gram of water can cool about 2 degrees per cubic meter of air. For outdoor air, spray cooling efficiency is very high. Theoretically, the energy required for spray cooling is the energy required to overcome the increase of water surface tension. When 1 cubic meter of water becomes a 10 micron cube, the energy required for its surface tension is about 43200 joules, while the evaporation latent heat is up to 2.2 billion joules, and the theoretical energy efficiency ratio is up to 50000. However, the air conditioning is limited by the thermodynamic law, and the theory of cooling 5 ℃ at 30 ℃ The high energy efficiency ratio is about 60.

The cooling effect of spray is greatly affected by air humidity, and the higher the relative humidity, the worse the effect. Therefore, the effect of spray cooling on the indoor is poor, especially for the indoor with poor ventilation, the effect of spray cooling is limited. Nowadays, the urban heat island effect is becoming stronger, and using greenery for cooling is not feasible Good measures. In fact, the greening cooling is because more than 99% of the energy is lost due to the evaporation of water into the vaporization heat of water. The cooling efficiency of spray cooling is much higher, but the spray cooling used in public places has high requirements for water quality.

So far, in most cases, the outdoor temperature is uncontrollable, and many times people have to carry it for several hours or longer in hot and dull places, such as open-air squares, sports venues, amusement parks, and so on. In these outdoor environments where air conditioning cannot be used, people must endure the ubiquitous heat.Now with the spray cooling system, the temperature of the large environment can be controlled locally. The water particles emitted by the spray cooling system into the air will absorb a lot of heat in the surrounding environment during the gasification process, thus reducing the temperature of the surrounding environment, which is an effective means of heatstroke prevention. In summer, when the city temperature reaches over 35 ℃, even with an umbrella and sunglasses, the direct sunlight and reflections from the ground still make people feel scorching hot. Under the action of the spray cooling system, the air temperature can be reduced to 25 ℃, and 14 ℃ in extreme environments, reaching the comfortable temperature of the human body. So even if you are outside in the hot weather, you still feel comfortable.

High pressure spray cooling equipment - principle

The wet spray cooling equipment uses the company's core water treatment technology to pressurize the tap water (0.002 μ m physical technology treatment) with a motor driven high-pressure pump, and spray it out through a special pipe and nozzle,Generate droplets with a diameter of micrometers from the nozzle, which disperse in the airAfter mixing with the air, it absorbs the heat in the air instantly to make it dissipate so as to achieve the cooling effect of spray. Control the operation and stop of the motor through an electrical control system.

High pressure spray cooling equipment——control mode

1.Manual control

Customers can manually control the humidifier on and off according to their own needs. (Suitable for local space humidification)

2.Automatic humidity control

Randomly equipped with a digital humidity automatic controller, customers can set the required humidity value according to their needs, with a setting range of 1% RH~99% RH and a control accuracy of ± 5% RH. The humidifier equipment works automatically within the set humidity value range without personnel supervision.

3.Time control

The host is equipped with a time control system, and customers can set the startup and shutdown time according to their own needs, with a range of 1 second to 99 hours for arbitrary adjustment. The humidifier equipment works continuously in a cycle within the set time without the need for personnel supervision.

4. Infrared sensing control

When someone enters the sensing range, a dedicated sensor detects changes in the infrared spectrum of the human body and automatically turns on the load. If the person does not leave the sensing range, it will continue to be turned on; After the person leaves, the load will automatically shut down with a delay. People work on the equipment, and people stop working when they leave the equipment, which is friendly, convenient, safe and energy-saving, and also demonstrates humanized care.
