Could the process or fluid system be affected by seasonal temperature changes?
These seasonal changes result not only in variances in ambient air temperature, but more importantly, in fluctuating supply water temperatures where cooling water is used to cool the fluid-circulating system. If seasonal weather changes significantly affect process efficiency, the fluid system should be designed to limit this effect accordingly (for example, an additional chiller system may be required). When changing from one heating/cooling medium to another, what is the heat transfer efficiency difference between the two mediums? It is important to know whether the process design allows for the use of a less efficient heat transfer medium. In some cases, changing the heating or cooling medium will require some improvement such as increased flow, pressure or surface area. Ultimately, the reason for using a fluid-heating system is to optimize process control. Once the process requirements have been established, choosing the correct fluid circulating control system is a key step in ach
