How many types of cooling towers are there? An important device used in any refrigeration or air conditioning. Types of cooling towers. Crossflow cooling towers use a splash fill that allows in-flowing. Counterflow cooling towers.
In a counterflow system, the in-flowing air travels in.
Hyperbolic cooling towers. It works on basic principle of heat transfer due to evaporation. The data of collected water can be reused by the boiler to feedwater through a feed check valve.
Mechanical draft — Uses power-driven fan motors to force or draw air through the tower. Heat transfer methods: 3. Both mechanical and natural draft towers can employ either counterflow or crossflow water and air movement methods. All hyperbolic cooling towers, however, are natural draft towers. No liquid or water is hence used for cooling in this type of setup.
Field-Erected-Towers (FEP) Field.
Cooling towers by build: 2. Due to the mechanism, this type of cooling tower is also called an evaporative cooling tower. This system consists of three main pieces of equipment: the recirculating water pump(s), the heat exchanger(s), and the cooling tower. Fill comes in two primary types: splash and film.
Fan assisted natural draft — A hybrid type that appears like a. Either type can be used in both crossflow and counterflow towers. But each type of fill has distinct advantages that make it more advantageous for specific conditions. Instea counterflow towers use pressurize pipe-type spray systems to spray water onto the top of the fill. Since air must be able to pass through the spray system,.
These towers rely on an exchange of heat between the machinery, the water in the tower , and the air passing through the tower. In a crossflow cooling tower , the air flow horizontally takes places. When a process or machine part begins to heat up, water in the cooling tower passes through a labyrinth in the structure, and as it passes through, it absorbs excess heat.
In this article explained about basic concepts of cooling tower , types of cooling towers , formula for cooling tower efficiency. INDUCED DRAFT HYBRID DRAFT TYPED BY AIR FLOW a. The two basic types of fill utilized in present day cooling towers are splash-type — Figure and film-type — Figure 2. Increased surface area allows for maximum contact between the air and the water, which allows for greater evaporation rates. There are two basic types of fill: splash fill and film fill.
The number of cells they have, e. We will now explain three types of mechanical draft cooling towers, and the advantages and disadvantages of each.
