2. Heat recovery ventilation - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_ventilation

   Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR) is a ventilation system that recovers energy by operating between two air sources at different temperatures. It is used to reduce the heating and cooling demands of buildings.

6. Waste heat recovery unit - Wikipedia

   en.wikipedia.org/wiki/Waste_heat_recovery_unit

   Capital cost to implement a waste heat recovery system may outweigh the benefit gained in heat recovered. It is necessary to put a cost to the heat being offset. [6] Often waste heat is of low quality (temperature). It can be difficult to efficiently utilize the quantity of low quality heat contained in a waste heat medium.

7. Recuperator - Wikipedia

   Types of recuperator, or cross plate heat exchanger. A recuperator (electro- end carbogidro-) - is a special purpose counter-flow energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the waste heat.
