Study on the Influence of Different Heating Charging Modes on Thermal Response
In order to explore the difference in the influence of different heating charging modes on human thermal response,this paper conducted an on-site investigation of residential buildings in Jiaozuo area in two heating seasons,measured the indoor and outdoor thermal environment parameters,and studied the thermal response status of the subjects.Through comparative analysis,it is found that the thermal comfort and thermal acceptability of households under flow rate charging model are higher than that under area charging model with the same operating temperature.Flow rate charging can reduce people's expectations of high-temperature environment,improve the acceptance of low-temperature environment,more conducive to energy saving and carbon reduction.The analysis shows that the factors affecting the subjective evaluation of households with different heating charging modes mainly lie in the comprehensive effect of heating cost and perceived control degree difference.The influence of different heating charge modes on thermal sensation,thermal comfort,and thermal expectation is different.Perceived control plays an active role in thermal sensation in both hot and cold environments.Thermal comfort is positively influenced by perceived control in the whole operating temperature range.At the same time,the proportion of flow charging to improve household expected warming is the most significant when the temperature is lower than 18℃.The above results can contribute to the reasonable selection of heating charging model,and further reveal the quantitative influence of charging model difference on thermal response.
