Determination of Heat Transfer Coefficient between Heated Floor and Space Using the Principles of ANSI/ASHRAE Standard 138 Test Chamber (LV-17-007)

In this study, heat transfer coefficients for radiant floor heating systems were investigated in a special test chamber that is one of the very first implementation of the ANSI/ASHRAE Standard 138 in the world. Radiant systems offer high energy and exergy efficient sensible heating and cooling potential. These systems can be directly coupled with low enthalpy, renewable or waste heat resources. Heat transfer coefficients are important design parameters for radiant systems that effects the heat transfer capacity of the heated/cooled surface to indoor. In this study, radiant, convective and total heat transfer coefficients for radiant floor heating are investigated experimentally.
