Evaporative condenser

Evaporative condenser, is commonly known as a name, also known as closed cooling tower. In fact, it is also known as closed cooling tower, the use of evaporation of spray water, brought out of the tower by the air, for cooling the circulating medium in the heat transfer tubes, the circulating medium is completely isolated from the outside world. Because the circulating medium being cooled is isolated from the outside world, completely closed, sometimes called evaporative condenser. Internal circulating medium, only cooling, no consumption without evaporation. As the heat exchanger tube outside the spray water vaporization, a large amount of water vapor and air mixing, humidity increases, by the axial fan, these saturated, high humidity, high enthalpy air out of the tower in the environment.

Air cooler

Air-cooled heat exchanger, referred to as air-cooler, is the ambient air as a cooling medium, the fan forced air swept across the finned tube outside, so that the high temperature process medium inside the tube for cooling industrial heat exchange devices. The air cooler consists of three basic parts: tube bundle, fan and frame, and auxiliary parts such as shutter and platform ladder.

Counterflow closed cooling tower

Counterflow closed cooling tower is named for the opposite direction of refrigerant and heat medium. The spray water is sprayed from top to bottom, and the air passes through at high speed from bottom to top. It is mainly composed of heat exchange coil, spray water system, air extraction system, frame shell.

Single air inlet combined flow closed cooling tower

Compound closed-circuit cooling towers, sometimes referred to as compound closed towers, are named for the mixing of spray water and hot air. The spray water flows from top to bottom, and the air is divided into two paths: one part of the cold air flows from top to bottom, and the other part enters horizontally from the side, exchanging heat with the falling spray water through the packing to reduce the temperature of the spray water.

Double-flow closed-circuit cooling tower

The spray water and wind direction form a compound form, with the wind being divided into two streams: one stream of cold air enters vertically from the top, and the other stream enters horizontally from the side. These streams cross and exchange heat with the falling spray water through the packing material, lowering the spray water temperature. Water droplets carried by the airflow are blocked by the side water collector and drip into the lower tank for recycling and reuse. Due to the thorough mixing of the spray water and cold air, the cooling and temperature reduction are significant, bringing the temperature closer to the wet-bulb temperature.

Crossflow closed cooling tower

Crossflow closed-circuit cooling tower, named for the horizontal direction of the spray water and hot air. The spray water flows from top to bottom, and the air enters horizontally from the side, passing through the heat exchanger coils. It exchanges heat with the falling spray water, lowering the spray water temperature. It mainly consists of heat exchanger coils, a spray water system, a draft system, and a frame shell.

Combined Dry-and-Wet Closed Cooling Tower

The dry-wet combined closed cooling tower, often referred to simply as "dry-wet combo," "dry-wet hybrid," or "dry-wet integrated" closed cooling tower, employs a unique design that combines both dry and wet coil systems. This innovative approach leverages the advantages of each method: the dry coil takes advantage of cooler local ambient temperatures to reduce the temperature of media exceeding the dry-bulb temperature—achieving this with minimal energy consumption since it only requires kinetic energy to drive airflow—while virtually eliminating water usage. Meanwhile, the wet coil further cools the media down to nearly the wet-bulb temperature, effectively addressing the limitation of the dry coil, which cannot achieve such low temperatures. As a result, this system significantly conserves water resources, making it highly popular among users.

Evaporative air cooler

An evaporative air cooler utilizes the evaporation of sprayed water, which is carried away by the air outside the tower to cool and exchange heat with the circulating medium inside the heat-exchange tubes. The circulating medium remains completely isolated from the external environment. Since the sprayed water vaporizes, a large amount of water vapor mixes with the air, increasing the humidity. Therefore, powerful ventilation equipment—namely, fans—are required to remove this saturated, high-humidity, high-enthalpy air from the tower. On the surface, it appears that the air is being cooled while simultaneously undergoing the evaporation of the sprayed water. Hence, it is commonly referred to as an evaporative air cooler or, in some cases, an evaporative cooler.

Evaporative condenser

An evaporative condenser is a common, informal term for a closed-circuit cooling tower. In fact, it is precisely a closed-circuit cooling tower: it uses the evaporation of sprayed water, carried away by air outside the tower, to cool and exchange heat with the circulating medium inside the heat-exchange tubes. The circulating medium remains completely isolated from the external environment. Because the circulating medium being cooled is entirely sealed off from the outside world, it is sometimes referred to as an evaporative condenser. The internal circulating medium is only cooled—there is no consumption or evaporation. After the spray water on the exterior of the heat-exchange tubes vaporizes, a large amount of water vapor mixes with the air, increasing the humidity. An axial-flow fan then draws this saturated, high-humidity, high-enthalpy air out of the tower and into the surrounding environment.

Air cooler

An air-cooled heat exchanger, often referred to as an air cooler, is an industrial heat exchange device that uses ambient air as the cooling medium. A fan forces air to flow across the outer surface of finned tubes, thereby cooling the high-temperature process fluid inside the tubes. An air cooler consists of three basic components: the tube bundle, the fan, and the supporting frame, as well as auxiliary components such as louvers and platform ladders.
