Chilled Water System

Design, commissioning and maintenance of chilled water networks (air cooled or water cooled), including piping and flushing.
What is Chilled Water System?.
Chilled water air conditioning systems are commonly used in applications that need large cooling capacity such as hypermarket, industrial process, commercial air conditioning such as offices and factories. More and more homes are using this system to air conditioned their entire house because of its cost-effectiveness and no hazard of having refrigerant piped all over the house.
As its name suggest, this system makes use of water as its secondary refrigerant. Chiller is used to remove heat from the water which is then circulated through other components to absorb heat from the space.
Water is non-corrosive, has specific heat value, fluid, non-toxic and is cheap. This makes an excellent choice compared to other secondary refrigerants such as sodium chloride brines, propylene glycols, ethylene, methanol or glycerin.
How Chilled Water Air Conditioning Works?
The chiller is the section of the system where an exchange of heat occurred between the water that goes to the building and the evaporator. The water leaves the chilled water evaporator at 45°F or 7°C. This chilled-water is then circulated through the entire building by the use of a pump.
The water cooled the space and pick up the heat and returns to the chiller at about 55°F or 13°C. The water temperature has been heated up by 10°F or 6°C after cooling the space. This process is then repeated.
