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-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
The counterflow closed cooling tower is named for the opposite directions of the refrigerant and heat medium. The spray water is sprayed from top to bottom, while the air flows rapidly from bottom to top. It mainly consists of heat exchange coils, a spray water system, an exhaust system, and a frame shell.
Single inlet air composite flow closed cooling tower
Composite flow closed cooling tower, sometimes referred to as composite closed tower, due to the spray water and hot air direction mixing and named, the spray water from the top downward flow, the wind is divided into two ways, a part of the cold air from the top downward flow, the other part, the side of the horizontal entry, through the filler and the falling spray water cross heat transfer, reduce the temperature of the spray water.
Double inlet air composite flow closed cooling tower
Spray water and wind into a composite form, the wind is divided into two ways: a cold wind from the upper vertical entry, the other side of the horizontal entry, through the filler and the drop of the
Cross-flow closed cooling tower
Cross-flow closed cooling tower, named by the direction of spray water and hot air horizontally, spray water flows downward from the top, the wind enters horizontally from the side, swept through the middle of the heat exchanger coil, and cross heat exchange with the falling spray water to reduce the temperature of the spray water. It is mainly composed of heat exchanger coil, shower water system, air extraction system and frame shell.
Dry and wet combined closed cooling tower
Wet and dry joint closed cooling tower, referred to as wet and dry joint, or wet and dry mixed or wet and dry combination of closed cooling tower, is the use of dry and wet coil combination of ways, a collection of the advantages of the two kinds of heat transfer, dry coil to take advantage of the advantages of the local temperature is low, will be higher than the dry-bulb temperature of the medium to reduce to close to the dry-bulb temperature, only to consume the kinetic energy of the driving air flow, there is no consumption of any water. Wet coiler will reduce the medium to close to the wet bulb temperature, to make up for the dry coiler can not be to the wet bulb temperature of the shortcomings. Therefore, it can save a lot of water resources, favored by users.
Evaporative air cooler, using the evaporation of spray water, carried out by the air out of the tower, for cooling the circulating medium in the heat exchanger tubes, the circulating medium is completely isolated from the outside world. As the spray water vaporization, a large amount of water vapor mixed with the air, humidity increases, the need for strong pumping equipment, that is, fans, these saturated, high humidity, high enthalpy air out of the tower. On the surface, it appears that it is the air that is cooled and at the same time there is evaporation of the spray water, referred to as an evaporative air cooler, sometimes called an evaporative cooler.
