Water Cooling Tower

By | Cooling Tower | No Comments

Water Cooling Tower – Cooling Water Systems are an essential part of process operations for many industries and public buildings. There are four problems commonly associated with water systems; corrosion, scale, fouling and microbiological contamination.

Clearwater products have been specifically designed to optimise system performance, cleanliness and heat exchange efficiency. Clearwater is the acknowledged leader in stable halogen treatment technology.

Regulatory requirements (ACOP L8) specify that cooling towers need to be controlled in order to prevent the proliferation of legionella bacteria. Legionnaires disease has become a major health and safety issue. Clearwater have the knowledge and experience to ensure that our clients comply with Government legislation

Natural Draft Cooling Tower

By | Cooling Tower | No Comments

“Natural Draft Cooling Tower” Natural contacts ambient air rising up through the tower either by forced draft using large fans in the tower. Natural draft is utilizes a tall chimney. Warm, moist air naturally rises due to the density differential compared to the dry, cooler outside air. Warm moist air is less dense than drier air at the same pressure.

This moist air buoyancy produces an upwards, current of air through the tower.Natural that appears like a natural draft setup, though airflow is assisted by a fan.This association is misleading, as the same kind of cooling towers are often used at large coal-fired power plants as well. Conversely, not all nuclear power plants have cooling towers, and some instead cool their heat exchangers with lake, river or ocean water.

The heat required to evaporate the water is derived from the water itself, which cools the water back to the original basin water temperature and the water is then ready to recirculate. Natural cooling towers have become the design standard for all natural-draft cooling towers because of their structural strength and minimum usage of material. The hyperboloid shape also aids in accelerating the upward convective air flow, improving cooling efficiency. These designs are popularly associated with nuclear power plants. That contact causes a small amount of the water to be lost as windage (W) and some of the water to evaporate.

Air Cooled Condenser

We are United Heat Exchanger providing solution for Air condensation system for all types of Thermal Power plants.In systems involving heat transfer, a condenser ( Air Cooled Condenser )is a device or unit used to condense a substance from its gaseous to its liquid state, typically by cooling it. In so doing, the latent heat is given up by the substance, and will transfer to the condenser coolant. Condensers are typically heat exchangers which have various designs and come in many sizes ranging from rather small (hand-held) to very large industrial-scale units used in plant processes. For example, a refrigerator uses a condenser to get rid of heat extracted from the interior of the unit to the outside air. Condensers are used in air conditioning, industrial chemical processes such as distillation, steam power plants and other heat-exchange systems. Use of cooling water or surrounding air as the coolant is common in many condensers.

 

Specifications :

  • A condenser unit used in central air conditioning systems typically has a heat exchanger section to cool down and condense incoming refrigerant vapor into liquid, a compressor to raise the pressure of the refrigerant and move it along,
  • A fan for blowing outside air through the heat exchanger section to cool the refrigerant inside.

Applications :

  • A typical configuration of such a condenser unit is as follows: The heat exchanger section wraps around the sides of the unit with the compressor inside.
  • In this heat exchanger section, the refrigerant goes through multiple tube passes, which are surrounded by heat transfer fins through which cooling air can move from outside to inside the unit.

Advantages :

  • There is a motorized fan inside the condenser unit near the top, which is covered by some grating to keep any objects from accidentally falling inside on the fan.
  • The fan is used to blow the outside cooling air in through the heat exchange section at the sides and out the top through the grating.
  • These condenser units are located on the outside of the building they are trying to cool, with tubing between the unit and building, one for vapor refrigerant entering and another for liquid refrigerant leaving the unit.
  • Of course, an electric power supply is needed for the compressor and fan inside the unit.
