Abstract

Double-layer pipe-embedded walls (DPEWs) can improve the thermal performance of buildings and reduce heating energy demand. However, on-site measurements on the thermal performance of DPEWs in real buildings remains lacking. Therefore, this study performed a field test on a lightweight DPEW heating system in an office building in Beijing over five months. Ground heat exchangers were used to supply water to the outer piping and an air source heat pump was used to supply water to the inner piping. The effects of outer and inner piping, radiative heat transfer enhancement, and different startup strategies on the thermal performance of the heating system and the indoor thermal environment were investigated. The results showed that the outer piping reduced the heat loss through the envelope with the utilization of shallow geothermal energy throughout the winter. Furthermore, the DPEW provided a heating capacity comparable to that of a radiant floor at the same supply water temperature while also providing heating load reduction. Additionally, increasing the interior surface emissivity of the DPEW enhanced the radiative heat exchange between the wall and indoor environment and reduced the vertical air temperature difference. Finally, the use of forced convection on the interior surface of the DPEW and the operation of outer piping shortened the startup time of the heating system. The results of this study provide a reference for the design and operation of DPEW heating systems.
