Kierrätyspumput

Kierrätyspumput, known in English as recycling pumps or sometimes as heat recovery pumps, are essential components in modern building systems designed to improve energy efficiency. They are a type of heat pump that utilizes waste heat generated by one part of a building or industrial process to provide heating or cooling elsewhere. Instead of solely relying on external ambient temperatures for heat exchange, recycling pumps tap into heat sources that would otherwise be dissipated or wasted.

These systems typically involve a refrigerant circuit that absorbs heat from a source, such as exhaust air from ventilation systems, wastewater, or even data center cooling loops. The absorbed heat is then compressed, increasing its temperature, and transferred to a colder sink, such as the building's heating system or domestic hot water supply. This process allows for the recovery and reuse of thermal energy, significantly reducing the need for primary energy sources like natural gas or electricity for heating.

The application of recycling pumps is diverse, ranging from residential buildings to large commercial complexes and industrial facilities. In residential settings, they can recover heat from outgoing shower water or kitchen exhaust. Industrially, they can be integrated into manufacturing processes to preheat incoming materials or generate steam. The primary benefit of recycling pumps is their contribution to reducing a building's or facility's overall carbon footprint and operational costs by maximizing energy utilization.
