Soojustagastuste

Soojustagastuste refers to the process of recovering heat from exhaust streams or waste heat sources and using it to preheat incoming air or other substances. This technology is widely employed in various industrial and building applications to improve energy efficiency and reduce operational costs. The fundamental principle behind soojustagastuste is heat transfer, where thermal energy is moved from a hotter medium to a colder one without direct mixing of the fluids.

Common types of soojustagastuste systems include heat exchangers, heat pipes, and heat recovery ventilators. Heat exchangers are devices designed to facilitate efficient heat transfer between two fluids separated by a solid wall. They come in various designs, such as plate heat exchangers and shell-and-tube heat exchangers, each suited for different applications. Heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) are specifically designed for buildings, recovering heat from outgoing ventilation air to temper the incoming fresh air.

The benefits of implementing soojustagastuste are significant. Primarily, it leads to substantial energy savings by reducing the amount of energy required to heat or cool incoming air. This, in turn, lowers fuel consumption and associated greenhouse gas emissions. In industrial settings, soojustagastuste can also improve process stability and reduce the load on primary heating or cooling equipment. The initial investment in soojustagastuste systems can be offset by long-term operational savings, making it an economically viable energy-saving measure.
