In the last fifteen years, the global market for air-cooled condensers has grown rapidly. China is a leading market, largely due to the recent spike in gas-fired combined-cycle power plants. This technology has been used in many other countries, but China has been a pioneer in the development of this technology. The air-cooled condenser is now installed in over 35,000 MW of new coal-fired power plants.
Air-cooled condensers are usually a smaller capacity version of their larger counterparts. They feature ample surface area and are cooled by air. Natural draft or fan-induced air blows across the coils, creating an air-chilled effect. Typically, these condensers are used for residential air conditioners, though industrial and commercial units also use them. Air-chilled condensers should be free of any external materials, as they reduce the airflow around their tubes and fins.
Another benefit of air-cooled condensers is their water-saving capabilities. Air-cooled condensers can be used in areas without adequate water supply, and they can be installed in remote areas. In addition, they are low-cost and produce very little noise. Regardless of the location, this type of condenser is a great option for thermal power plants. You'll be able to reduce the cost of building a water reservoir and the water consumption while the equipment is in operation, and they'll reduce your carbon footprint.
Another advantage of an air-cooled condenser is that it has a larger surface area than its water-cooled counterpart. This means the air-cooled condenser can operate at a higher temperature than its water-cooled counterpart. However, this means that it needs a larger compressor, which will require more power. Therefore, it's important to consider your application when choosing a condenser.
Aside from the initial cost, air-cooled systems require less maintenance than water-cooled ones. The former requires routine care about twice a year, while water-cooled ones need more frequent maintenance. A major advantage of air-cooled systems is that they don't require a mechanical room, which can be a plus in some homes. They are also less expensive than water-cooled models, so you may save money in the long run.
