heat recovery
heat recovery
Heat recovery is the capture and re-use of heat that is the by-product of a process, which would otherwise be lost and wasted.
The process could be intrinsic to the building such as general heating for occupants for example or a business activity such as heat build-up by IT equipment, furnaces etc. Heat recovery can reduce the energy consumption of the process itself or provide useful heat for other purposes.
For example refrigeration systems can’t make heat disappear – they just move it from one place to another. It’s possible to recover some or all of this heat for useful heating of air or water elsewhere.
Heat recovery has applications, meaning waste heat can be captured from these processes; boilers, refrigeration, ventilation, industrial processes (e.g. drying, curing, heat treating) to provide useful heat for other purposes.
