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.

Evaporative condenser

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.

Air cooler

Counterflow closed cooling tower, so named because the refrigerant and heat medium flow in opposite directions, with the spray water sprayed from top to bottom and the air flowing upwards at high speed from below. It mainly consists of heat exchange coils, a spray water system, a draft system, and a frame shell.

Counterflow closed cooling tower

Counterflow closed-circuit cooling towers, sometimes abbreviated as counterflow closed towers, are so named because the spray water and hot air flow in a mixed direction. The spray water flows from top to bottom, and the air is divided into two streams. One stream of cold air flows from top to bottom, while the other stream enters horizontally from the side, exchanging heat with the falling spray water through the fill media to lower the spray water temperature.

Single-inlet composite 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.

Double-flow closed-circuit 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.

Principles & Applications

Counterflow closed cooling tower


★Air and spray water flow in the reverse direction;

★Low-temperature, low-humidity air is drawn into the tower from the inlet grille, due to the negative pressure caused by the fan;

★High temperature, high humidity air, from the top of the tower fan, outward discharge;

Closed cooling tower and open tower what is not the same!

Closed cooling tower and open tower what is not the same!

By spraying the circulating water on the PVC packing, the heat exchange is achieved through the contact between water and air, and then the fan drives the air circulation in the tower to bring out the hot air after heat exchange with water, so as to achieve cooling. This cooling method, the first phase of the investment is relatively small, but the operating cost is higher (water consumption, power consumption).
