A subspace based method for modelling building’s thermal dynamic in district heating system and parameter extrapolation verificationSpringer Science and Business Media LLC - Tập 16 - Trang 2145-2158 - 2023
Junfeng Zhang, Lanbin Liu, Yameng Liu
The district heating system (DHS) consumes a lot of energy in winter, and its control accuracy needs to be improved urgently. To apply advanced process control (APC) in DHS, the thermal dynamic model of the existing buildings is essential. This paper uses the subspace method which is a data-driven approach for modelling the thermal dynamics of the building. The model’s performance is analyzed usin...... hiện toàn bộ
Comparison of space cooling/heating load under non-uniform indoor environment with convective heat gain/loss from envelopeSpringer Science and Business Media LLC - - 2020
Shuai Yan, Xianting Li
The indoor parameters are generally non-uniform distributed. Consequently, it is important to study the space cooling/heating load oriented to local requirements. Though the influence of indoor set point, heat sources, and ambient temperature of convective thermal boundary on cooling/heating load has been investigated in the uniform environment in previous research, the influence of these factors,...... hiện toàn bộ
Window purifying ventilator using a cross-flow fan: Simulation and optimizationSpringer Science and Business Media LLC - Tập 9 - Trang 481-488 - 2016
Jiayu Li, Yuefei Hou, Junjie Liu, Zhiqiang Wang, Fei Li
The window purifying ventilator is a relatively new idea that involves replacing one part of the window frame with a ventilator, for which the core component is a cross-flow fan (CFF). When a CFF is applied to the window purifying ventilator, a filter should be added, and its casing should be modified. In this paper, first, time-accurate solutions with a sliding mesh technique were developed for m...... hiện toàn bộ
Agent-based modeling and simulation of stochastic heat pump usage behavior in residential communitiesSpringer Science and Business Media LLC - Tập 13 - Trang 803-821 - 2020
Shuqin Chen, Hong Zhang, Jun Guan, Zhiqin Rao
A simulation method of stochastic heating behaviors in residential communities is developed, which is helpful to accurately predict regional dynamic electricity loads. In this method, the corresponding relationship among the structure of family members, the ownership and the locations of heat pumps should be established for each family firstly. The residents need be divided to several types based ...... hiện toàn bộ
