Efficiency improvement in aerothermal household heating systems

Carlos Armenta-Déu, Julián Arenas


This paper shows a new method to improve the aerothermal household heating system. The development bases the design on a forced convection assistance unit attached to the water radiators used for heating the house. The proposed design applies to any household heating system with wall radiators powered by an aerothermal unit. The household heating protocol is enhanced thanks to a quicker rate of room temperature rising, which allows setting up the heating PID curve to a lower value, reducing the energy consumption and increasing the heating system efficiency. The Aerothermal Coefficient of Performance (COP) rises between 20% and 28.5% depending on operating conditions.
