Once the loop is closed and this hunting process starts the loop is referred to as locked and it repeats continuously as long as the loop is closed This hunting approach may seem somewhat peculiar but it s the way it s been engineered on cars for over 30 years As for the feedback instead of it resulting in offset as on the ignition system it results in what I call override In

Closed Loop Systems

A typical open loop system would be a cooling tower system where the flowpath is linear fluid transfer between two vessels Conversely closed loop systems as the title suggests are closed piping circuits where the pumped fluid circulates in a closed loop without any exposure to the local environment and typically without transfer of fluid into or out of the closed loop Examples of

Water from abandoned mines as a heat source practical

It can be seen at Caphouse that while the open loop mine water scheme is based on mine water at 14 °C the closed loop scheme requires a temperature differential to absorb heat from the lagoon to the heat transfer fluid Thus the fluid returns from the lagoon to the evaporator typically at around °C This together with the parasitic power required to circulate the heat transfer

In a nutshell closed loop recycling is the process by which a product is used recycled and then made into a new product — therefore not ever entering landfill This means that these waste types are better for the environment than those that are recycled but have to be mixed with virgin materials to make new products this is open loop recycling and of course those that can t be
