All-Water Supply Systems

With the purpose of cooling control zone within a building, water supply system, supply of chilled water in the zone. As the size and number of floors growing, all-water systems are becoming more popular. They are also popular, where space for pipelines and ducts, is very limited. 5/8-inch outer diameter pipe carrying chilled water in normal conditions and provides the same cooling capacity zone, as it makes 8 inches in diameter, low-speed air duct or 5 inches in diameter, high speed air duct.

In the system water, cooling water circulates in each of the zones. A special type of the target device gets chilled water. This is evident from mounted on the outer wall, but styles are also available that can be installed in a corner, above the ceiling, or is mounted flush with the inside wall.

Each chilled water fan coil is, in fact, a small unit, which includes a chilled water coil fan and filter. The return air is drawn into the unit and through the filter suction fan. He then passed over the heat exchanger, through which the cooling water flows. Normal cooling water temperature in the range from 40 48F. air cools and dries as it passes through the coil. Grill on the top of the unit directs the cold air in space, thus giving the movement of air in the room. Cold air is mixed with room air, it absorbs the heat in the room. The cycle is repeated until the fan is running and the chilled water is supplied to the coil.

The heat absorbed from space chilled water supplied through a water pipes for cooling. This is the same kind hmm shown earlier for air system that uses chilled water coil at each air handler. All cooling system cooler and method of removing heat from may differ. This diagram shows the most common applications. Chillers with water cooled condenser are located in the tower and in the open air...
