Six characteristics of water curtain:
1. There are no special requirements for water quality, just tap water;
2. Significant cooling and purification effects;
3. Low power consumption, only 10% of central air conditioning;
4. Reasonable funding can save costs such as aluminum alloy glass doors and windows for newly built factories;
5. Long service life, 8-10 years of normal use;
6. With good ventilation, it can reduce 5-8 ° C.
What is a cooling water curtain
Use the unsaturated nature of air and the evaporation and heat absorption of water to cool down. Cold water first wets the cooling water curtain, and outdoor hot air is pumped into the room by a fan. After being cooled by the cooling water curtain, it becomes cool cold air and enters the room for cooling purposes. The hot and turbid air inside the room is pumped out of the room by a fan.
working principle
Cooling water curtain devices are generally divided into two types: cooling water curtain wall plus negative pressure fan and external independent cooling water curtain fan. The working principles of these two devices are the same, but the installation methods are different. Cooling water curtain walls with negative pressure fans are mainly used in workshops where space is easy to close and cooling requirements are high. External mounted independent cooling water curtain fan (environmental friendly air conditioner) is suitable for workshops with low cooling requirements and difficult to close.
Factors affecting the cooling effect of cooling water curtain
The efficiency of a cooling water curtain cooling device depends on factors such as the performance and area of the cooling water curtain, water temperature, plant building, air temperature, and humidity. The requirements for cooling water curtain materials mainly include water adsorption capacity, ventilation and breathability, porosity, and durability. The calculation of the area of the cooling water curtain during installation is only theoretical, and the actual application must be adjusted based on the actual situation, especially the number of employees in the workshop. It has been observed that the colder the water flowing through the cooling water curtain, the better the indoor cooling effect, because evaporation absorbs more heat. It is generally recommended to use cold deep well water for cooling the water curtain. At the same time, when the water temperature rises after several cycles (>24 ℃), the water should be replaced
1. Basic introduction: What are the benefits of using a water curtain to cool down in summer
The English name of the cooling water curtain is (CELdek), which is divided into imported and domestic materials. The imported materials from Sweden actually have better cooling effect than the domestic ones.
The water curtain wall cooling system is based on the principle of water evaporation and heat absorption, as well as the principle of negative pressure ventilation, to discharge waste gas and dirty air from the factory building and relieve high temperature and stuffiness.
After installation, it can effectively improve the hot and stuffy environment of the factory building, rapidly reducing the temperature inside the factory building (a high temperature environment of 32-45 ℃) within 10 minutes and maintaining the temperature at 26-30 ℃. This is a comfortable working environment for the human body, which can improve employee work efficiency and maintain product quality.
Its cooling and ventilation effect can effectively solve the problems of high temperature, stuffiness, and air pollution in 95-99% of factory buildings. The temperature effect is obvious; It can be used for both blowing and ventilation, making it a choice for cooling and ventilation in greenhouses and other areas.
Cooling water curtains are popular in the current industrial industry, and their cooling and environmental protection effects, as well as energy-saving effects, are not available in other cooling equipment.
2. Cooling principle
Wet curtain (water curtain) cooling mainly utilizes the physical principle that water absorbs heat from the air during the evaporation process of water, causing the air temperature to decrease. In practice, it is used in conjunction with a negative pressure fan. The wet curtain is installed on one end of the gable or side wall of a closed building, and the fan is installed on the other end of the gable or side wall. The cooling fan extracts indoor air, generating negative pressure to force outdoor air to flow through the porous wet curtain surface, converting a large amount of heat in the air and forcing the air entering the room to decrease by 10-15 ℃, and continuously introducing it into the room for heatstroke prevention and cooling.
in a timely manner.
