Cooling towers are devices for extracting the cold water and reject heat to the atmosphere. Heat rejection is achieved through a natural process called evaporation. This occurs when water comes into direct contact with the air inside the tower. The cooling efficiency is an important factor and maximum efficiency occurs by exposing the maximum water surface with maximum air flow for as long as possible. Cooling towers that run on water are designed in two different configurations. The first configuration is called counter flow cooling tower while the second configuration is the cooling tower cross-flow. These are just settings which indicate the direction of airflow when related to the direction of water flow. These two factors are also important as the calculation of the efficiency of the tower and heat rejection. In the cross flow type, the air flow is perpendicular to the water flow as the water moves down through the fill. The air flow enters the vertical faces of the tower and meets the filling material through which the water flows downwards by gravity. The air flows past the filling and through the cooling water and the water stream to a lower temperature and further provide chilled water for purposes such as air conditioning or power generation. Depending on the purpose of cooling these devices can be small, designed to cool only a few liters per minute, or cooling can be very large hundreds of thousands of gallons of water every minute. These types are used in large industrial companies such as power plants. Cooling towers cross flow are in contrast to the counter-flow towers where the air travels upward through the tubes or full, which is opposite to the downward movement of the water. The rule of thumb is not to replace a cooling tower with a cross-flow or counter flow tower do otherwise. The main requirement for a change of this type is a thorough engineering evaluation of the entire cooling system with pump systems. Cross flow towers have certain advantages over other types of cooling towers, working for the benefit of the company. For starters, have a lower lift height and therefore have lower operating costs. In addition, variations accept water easily flow without changing the distribution system. They are also easy to maintain, as it is easy to access vital parts. These are best for situations where the requirement is more towards the pumping and piping costs minimal. Cross flow towers also operate with minimal noise and have minimal operating costs. Therefore, also shown best in situations where the easy maintenance is a concern. For these reasons, they are a practical choice for many industries where cooling is the main concern while focusing on concerns such as ease of use, maintenance and operating costs of the cooling device.
