Closed Loop Cooling Water System

Overview of closed loop water system.

Closed loop cooling water system.

Closed cooling water system. 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. 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. With very real concerns about the higher water consumption of open loop systems closed loop cooling technology is gaining broader appeal every year.

Thermal precision closed loop cooling systems are designed to substantially decrease or even eliminate the hidden costs of operating your water cooled equipment. The critical difference between these is the amount of exposure the water has to the air. A closed loop cooling system is a more complex system which is very similar to a car s cooling system. A closed loop system would be from the chiller to the air handling units.

When properly designed for the commercial or industrial process cooling load both system types can offer unparalleled energy efficiency reliability and longevity. This loop does not require continuous city. For cost efficient and long lasting closed loop cooling count on alfa laval s broad range of plate heat. As the water flows through the tower it is open to the atmosphere.

Depending on your current operation installed pay back on a closed industrial cooling system can be achieved in months. In a closed system water circulates in a closed cycle and is subjected to alternate cooling and heating without air contact. 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. Because of evaporation at the cooling tower city water is introduced to replace the evaporated water.

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.
