Closed Loop Cooling Water System

As the water flows through the tower it is open to the atmosphere.

Closed loop cooling water system.

When properly designed for the commercial or industrial process cooling load both system types can offer unparalleled energy efficiency reliability and longevity. A closed loop system would be from the chiller to the air handling units. With very real concerns about the higher water consumption of open loop systems closed loop cooling technology is gaining broader appeal every year. For cost efficient and long lasting closed loop cooling count on alfa laval s broad range of plate heat.

The engine is cooled by a special coolant fluid which transfers the heat from the engine to the heat exchanger which is then cooled by the external water. Cooling or heating systems that use water can have one of two main types of systems for dissipating heat acquired by the liquid closed loop or open loop. Heat absorbed by the water in the closed system is normally transferred by a water to water exchanger to the recirculating water of an open recirculating system from which the heat is lost to atmosphere figure 32 1. A closed loop cooling system can exchange heat with the main cooling water system in conventional tube and shell heat exchangers or plate and frame heat exchangers.

To cool key processes in petrochemical plants refineries power plants and other heavy duty industrial environments many plant owners and operators rely on closed loop cooling as the preferred cooling method. Each has its advantage when part of a cooling or heating system. Closed cooling water system. The critical difference between these is the amount of exposure the water has to the air.

Overview of closed loop water system. A closed loop cooling system is a more complex system which is very similar to a car s cooling system. Depending on your current operation installed pay back on a closed industrial cooling system can be achieved in months. An open loop is from the chiller to the cooling tower.

In a closed system water circulates in a closed cycle and is subjected to alternate cooling and heating without air contact.
