Evaporative Air Cooler

I. Overview

Evaporative air cooler, utilizing the evaporation of spray water, carries the air out of the tower for cooling and heat exchange of the circulating medium inside the tubes, with the circulating medium completely isolated from the outside.

Due to the vaporization of the spray water, a large amount of steam mixes with the air, increasing humidity, which requires a strong exhaust fan, or blower, to remove the saturated, high-humidity, and high-enthalpy air from the tower. On the surface, it is just the air being cooled, with the evaporation of the spray water, commonly known as an evaporative air cooler, sometimes also referred to as an evaporative cooler.

Section 2: Working Principle

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

2. Interfacial Heat Exchange: Sprayed water and air are completely isolated from the circulating medium, with no contact at all, only heat exchange, no contact.

III. Key Advantages

1. No Evaporation: Only temperature reduction, no evaporation or consumption; the circulating medium is completely isolated from the external air, with no contact at all. This ensures there is no medium evaporation, consumption, or impurities entering, guaranteeing the stability of the internal medium composition.

2. Non-scaling: Due to no evaporation, the concentration of scaling ions such as calcium, magnesium, and sulfate in the medium remains unchanged, hence scaling does not occur.

3. Easy Maintenance: All coils are fully visible for easy maintenance and quick repairs.

4. The equipment features four-sided air intake with low air resistance, resulting in reduced fan power.

Section 4: Application Scenarios

Commonly used in heavy industries such as steel metallurgy, casting smelting, petrochemicals, chemical light industry, machinery and electricity, it resists scaling, reduces evaporation, and is often used for cooling desalinated water and pure water. It cools within sealed heat exchange tubes, completely isolated from the external atmosphere.

Six, Case Studies

Due to its use in iron and steel metallurgy, chemical light industry, textile, petroleum refining, etc., it typically requires a flow rate of 500 m3/h or more. The dimensions are generally large, and all products are customized. They are designed based on transportation conditions, usage site, and production process parameters, without a unified standard.
