Pump 5 contributes to which of the following systems?

Pump 5 contributes to the heat recovery piping system because this system is designed to capture excess heat generated during various processes and reuse it, usually to heat other fluids or spaces. In these systems, pumps play a crucial role in circulating fluids to collect heat from wherever it is available and deliver it to areas where it can be utilized effectively.

Heat recovery piping systems often integrate pumps specifically designed to handle fluids that may have varying temperatures and flow conditions. The pump’s efficiency and suitability for moving heated fluids make it essential for optimizing energy use and enhancing the overall efficiency of the system.

In contrast, options such as central air conditioning, geothermal heating, or domestic hot water represent unrelated applications where pumps might still be involved but do not specifically connect to the function of heat recovery piping. Each of these systems has its own unique requirements and operating principles that differ significantly from those of a heat recovery system.
