Experimental study on heat transfer characteristics of interior walls under partial-space heating mode in hot summer and cold winter zone in China

Energy-quota-based integrated solutions for heating and cooling of residential buildings in the Hot Summer and Cold Winter zone in China

“…The energy use mode has the characteristics of partial-space and intermittency, which relate to occupants' behaviour [24,25]. Since the strategic and technical solutions for residential buildings are closely tied to residents' behaviour and climate conditions, they will be quite different from those of other regions.…”

Improvements in Energy Saving and Thermal Environment after Retrofitting with Interior Insulation in Intermittently Cooled Residences in Hot-Summer/Cold-Winter Zone of China: A Case Study in Chengdu

“…In this case, whether the internal envelope is insulated or not can greatly affect the effectiveness of the air conditioning. Field experiments conducted by Li Nan and Chen Qiong (2019) [39] showed that whether an adjacent room is heated or not directly affects the surface temperature and total heat consumption of the interior walls. Compared to the heated neighboring rooms, when the neighboring rooms are not heated, the heat flux density on the surface of the interior walls increases by 29.8-52.2%, resulting in an increase of 5.2-7.2% in the total amount of heat supplied to the room.…”

Heat Transfer and Energy Consumption of Passive House in a Severely Cold Area: Simulation Analyses

“…Further, passive buildings are simultaneously required to comply with fire prevention specifications. At present, the primary four kinds of thermal insulation materials applied for passive external walls are classified as follows [28]: (1) Graphite-Molded Expanded Polystyrene Sheet (GEPS), fabricated by adding graphite particles and infrared reflector agents in the production of normal Expanded Polystyrene Sheet (EPS), which presents low thermal conductivity and high flame retardancy; (2) Extruded Foam Polystyrene Sheet (EFPS), which is obtained by uniformly extruding the molten polystyrene and appropriate additives from a pressing extruder, has smooth surfaces without pores, high tenacity, low hydrophilicity, and excellent heat preservation performance; (3) Polyurethane Foam Board (PUFB) with a small heat transfer coefficient can effectively reduce the wall thickness but at high cost; (4) Stone Wool Board (SWB) is an inorganic material with low heat transfer coefficient and high thermal resistance. The thermal insulating properties of various materials are listed in Table 5.…”
