Evaporative air cooler

Evaporative air coolers utilize the evaporation of sprayed water, which is then carried out of the tower by air, cooling the circulating medium within the heat exchange tubes. The circulating medium is completely isolated from the outside environment. Since the sprayed water vaporizes, a large amount of water vapor mixes with the air, increasing humidity. Powerful exhaust equipment, namely fans, are needed to remove this saturated, high-humidity, high-enthalpy air from the tower. On the surface, it appears that the air is cooled while the sprayed water evaporates; hence the term evaporative air cooler, sometimes also called an evaporative cooler.

Overview

Evaporative air coolers utilize the evaporation of sprayed water, which is then carried away by the air outside the tower, cooling the circulating medium within the heat exchange tubes. The circulating medium is completely isolated from the outside world.

Since the sprayed water vaporizes, a large amount of water vapor mixes with the air, increasing humidity. Powerful exhaust equipment, i.e., fans, are needed to carry this saturated, high-humidity, high-enthalpy air out of the tower. On the surface, it appears that the air is cooled, while there is also evaporation of the sprayed water; hence the term evaporative air cooler, sometimes also called an evaporative cooler.

Working Principle

► Latent Heat of Vaporization: Similar to closed-circuit cooling towers, it relies on the evaporation of the spray water outside the heat exchange tubes to absorb the latent heat of vaporization, carrying away the thermal energy of the industrial circulating water medium inside the closed heat exchange tubes;

► Indirect Heat Exchange: The spray water and air are completely isolated from the circulating medium, with no contact, only heat exchange, no contact.

Main Advantages

► No Evaporation: Only cooling, no evaporation, no consumption. The circulating medium is completely isolated from the outside air, with no contact. There is no evaporation consumption or impurity entry of the medium, ensuring the stability of the internal medium components.

► No Scaling: Due to the absence of evaporation, the concentration of scaling ions such as calcium, magnesium, and sulfate in the medium does not change, therefore, scaling will not occur.

► Easy Maintenance: The coils are fully visible, making maintenance and inspection easy;

► The equipment has four-sided air intake, low air resistance, and reduced fan power.

Application Scenarios

It is widely used in heavy industries such as iron and steel metallurgy, casting and smelting, petrochemicals, chemical and light textiles, and machinery and power. It is not prone to scaling, reduces evaporation, and is often used for cooling desalinated water and pure water, cooling within closed heat exchange tubes, completely isolated from the outside atmosphere.

► Iron and Steel Metallurgy: Blast furnaces, continuous casting and rolling, crystallizers, air compressors, etc.;

► Large-scale Casting: Melting furnaces, frequency converters, quenching liquids, etc.;

► Petroleum Refining: Reactors, smelting furnaces, heat exchangers, etc.;

► Chemical and Light Textiles: Reactors, etc.;

► Air Conditioning and Refrigeration: Compressors, etc.;

Brand Advantages

21 years of focus, professional because of focus, rich experience, high quality.

21 patents, patent support, reliable technology, excellent performance, stable operation

40 acres of land, strong strength, strong backing, long-term cooperation, worry-free after-sales service

Case Studies

Since they are used in iron and steel metallurgy, chemical and light textiles, and petroleum refining, the flow rate is generally above 500m3/h, and the external dimensions are relatively large. They are all customized products, designed according to transportation conditions, usage sites, and production process parameters, and there is no unified standard.
