“…In addition, the increased efficiency of heat supply systems results in lower investment (i.e., lower capacity of heat pump) and operational costs (i.e., less electricity consumption). A lower supply temperature of the heating system might also reduce the energy consumption of buildings [3]. Finally, lower supply temperatures reduce the thermal stresses and distribution heat losses of district heating systems.…”

“…This heating mode's control strategy is more effectively implemented and can reduce heating energy consumption. 4,5 In order to create a non-uniform indoor environment, this paper focuses on a distinct type of local heating that occurs in different areas of the same room. Current research on the local heating of the same space includes calculations of the heating load, indoor airflow distribution, thermal comfort and air quality, amongst other factors.…”

“…Local heating has an energysaving effect and contributes to the back heating effect. 12 Preliminary literature reviews [1][2][3][4][5][6][7][8][9][10][11][12] reveal that local heating environment studies frequently employ numerical simulation methods, whereas local heating thermal comfort studies favour experimental methods. However, both local heating environment studies and thermal comfort studies are still case studies of specific heating areas, and the applicability of these findings is debatable when the demand area's size or location changes.…”

Insufficient partial heating based on the actual thermal demand of people or spaces becomes a revolutionary approach to reducing energy consumption. However, current research on local heating is case-specific and lacks standardized and unified guidelines for describing the formation of non-uniform indoor environments. In this paper, the local temperature imbalance rate and Part-Air Diffusion Performance Index (P-ADPI) parameters are proposed for multidimensional evaluation of indoor non-uniform environment characteristics. On the basis of the characteristic parameters, a unified indoor environment characterization partition was performed in the study. The results indicate that an increase in air supply temperature and air supply velocity could enlarge the characteristic core area and transition area. The intervention of background radiation conditions could intensify the inhomogeneity of the indoor environment, but it would have a minimal impact on the classification of the environment. The background radiation condition was incorporated into the characteristic boundary function model as a correction factor, and the correction factors for determining the background radiation temperature, position and the area fall within the ranges of 0.97–1.44, 0.82–1.01 and 0.98–1.10. This study has provided the groundwork for future studies on the local convection heating and the creation of a non-uniform indoor environment.
