What are the three types of cooling towers?
What are the three types of cooling towers?
The types of cooling towers based on the air flow generation are Natural draft, Mechanical draft, Cross-flow and Counter-flow towers.
- Natural Draft cooling towers use the design and shape of the tower itself to move up the air naturally using fans.
- Mechanical Draft towers tend to use a fan to force the air.
Which is the most efficient cooling tower?
Counterflow (induced draft) systems are considered the most efficient of the two. Crossflow (forced draft) towers distribute hot water perpendicularly to the air flow, while counterflow towers distribute hot water directly into the air flow.
What are the two types of cooling towers?
There are three main types of cooling towers that are defined by how water or air pass through them. These types include crossflow, counterflow, and hyperbolic. There are also two varieties classified solely on airflow, known as induced draft and passive draft cooling towers.
What are the different types of cooling tower explain any one?
There are two types of natural draught cooling tower, rectangular timber tower and reinforced concrete hyperbolic tower. 2) Mechanical or Forced Draught Cooling Tower: In this type of cooling tower, fan is used to circulate the air. When power plant runs on peak load, it requires a very high rate of cooling water.
What is the difference between cooling tower and chiller?
Mechanical draft cooling towers rely on fans to pull cool air into the system to remove the heat from water. Chillers utilize compressors, evaporator heat exchangers and condenser heat exchangers. The condenser heat exchanger is the major component that rejects heat from the chillers to air.
How do you calculate TR on a cooling tower?
Multiply 500 times the water flow rate, times the temperature difference, divided by 12,000 or 500 x q x dt/12,000. The result is the tons of capacity of the cooling tower.
How do you calculate the efficiency of a cooling tower?
Cooling Tower Efficiency Calculations
- Approach = Cold Water Temperature – Wet Bulb Temperature.
- Cooling Tower Efficiency =
- (Hot Water Temperature – Cold water Temperature) x 100/
- (Hot Water Temperature – Wet bulb temperature)
What is the meaning of TR in cooling tower?
Ton of Refrigeration
Ton of Refrigeration (TR): Ton of Refrigeration (abbreviated as TR) is an important historical unit of refrigeration capacity. Originally 1 TR was defined as the rate of heat transfer required to make 1 short ton (2000 lbs) of ice per day from water at 0oC.
What are the different types of condenser?
A condenser’s function is to allow high pressure and temperature refrigerant vapor to condense and eject heat. There are three main types: air-cooled, evaporative, and water-cooled condensers.
How many types of cooling systems are there?
There are six basic types of liquid cooling systems: Liquid-to-liquid. Closed-loop dry system. Closed-loop dry system with trim cooling.
What is tower technology?
Tower Technology, Inc. (TTI) is an independent engineering organization, established in 1981, that offers engineering consulting for antenna supporting structures.
What is function of cooling tower?
Cooling towers are heat rejection devices used to transfer process waste heat to atmosphere. Cooling towers may either use the evaporation of water to reject process heat and cool the working fluid to near the wet bulb air temperature on air to cool working fluid to near dry bulb air temperature.

What happens in cooling tower?
A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature.
