Closed Loop Water System Definition

The system whose control action is free from the output is known as the open loop control system.

Closed loop water system definition. Closed circuits operate as a closed loop or closed system meaning that they are effectively sealed and the water inside the system is not exposed to the atmosphere. Open loop system closed loop system. Controller and controlled process. Closed loop system a control system with a feedback loop that is active closed loop control system.

Closed loop water system definition. A closed water heater system means that the hot water cannot expand beyond the valves and mix with the municipal water. Closed loop cooling water system. The valves that are usually found in the closed systems are the check valve pressure reducing valve mixing valve backflow preventer and other.

Examples of closed loop systems include hot oil circuits cooling chilled water systems hot water heating and air conditioning systems. Open circuits deposit the cooling water into an open cooling tower that exposes the surface of the water to the air. This means that a closed loop system contains a fixed volume of water that recirculates and tends to suffer only negligible water losses. Figure 1 provides an illustration of a closed loop fresh water cooling system consisting of heat exchangers circulating pumps orifice plates and over 300 m of pipework.
