COEFFICIENTS OF THE TRANSFER-FUNCTIONS AND THERMAL IMPEDANCE OF WALLS.

COEFFICIENTS DE LA FONCTION DE TRANSFERT ET IMPEDANCE THERMIQUE DES MURS.

Author(s) : CARRASCO J. A., GARCIA DE VINUESA S., DOMINGUEZ M.

Summary

THE AUTHORS GIVE A SIMPLE METHOD TO DETERMINE THE COEFFICIENTS OF THE TRANSFER FUNCTIONS BY MEANS OF ELECTRIC ANALOGY. USE WAS MADE OF A UNITARY TRIANGLE SIGNAL THAT PERMITS TO SOLVE IN AN EASY WAY, THE HEAT TRANSMISSION EQUATIONS WHEN THEY ARE STUDIED FOR THE BUILDING ENVELOPES. IN THE PARTICULAR CASE OF SINUSOIDAL TEMPERATURE VARIATIONS THE SOLUTION IS EASIER WITH THE NEW CONCEPTS OF THERMAL IMPEDANCE AND DEPHASING THAT ARE PROPOSED. THE EFFECT OF THE RELATIVE POSITION OF THE ELEMENTS AND THE TEMPERATURE FREQUENCY ON THE INSULATING POWER IN THE SAME WALL HAS BEEN INVESTIGATED.
