The air source heat pump compensation curve represents a sophisticated temperature management strategy that dynamically adjusts heating system flow temperatures based on external ambient conditions. This intelligent mechanism ensures optimal thermal performance by precisely modulating water temperature relative to outdoor temperature variations, enabling homeowners to maintain consistent indoor comfort while maximizing energy efficiency and reducing operational costs.
What Is the Air Source Heat Pump Compensation Curve?
The compensation curve represents a mathematical relationship between outdoor temperature and heating system flow temperature, enabling precise thermal management. This sophisticated algorithm allows heat pumps to adapt their performance dynamically, ensuring consistent indoor comfort across varying environmental conditions.
Key Components of the Compensation Curve
