An extended top of the roof can induce the upflowing wind which flows close to the wall and in this way it increases the intake airflow rate in the air gap.
Uncertainty and sensitivity analysis of natural ventilation in high-rise apartment buildings | 2007 | English
Quantification of natural ventilation rates is an important issue in HVAC system design.
The buoyancy-driven natural ventilation of a room with large lower and higher level openings is investigated by both theoretical analysis and CFD simulation.
Assessments based on CFD snapshots of stable conditions within strongly transient domains do not address many aspects of performance associated with occupant interventions, control actions or changing climate. Such domains (e.g.
A mathematical model for simulating airflow in solar channel of the insulated Trombe solar wall system is proposed.
This paper includes the results of empirical measurements in and computational modeling of atria. Five atria with different designs were considered.
Improving natural light in classroom spaces with local trees: Simulation analysis under the desert conditions of the UAE | 2007 | English
The study investigates the use of local trees in the UAE to improve visual performance and lighting quality in typical classrooms.
This paper presents the simulated results of human evacuation in a large space building. Two different models, Cellular Automata (CA) model and social force (SF) model are adopted.
Study on optimizing the operatoin of heat source equipments in an actual heating/cooling plant using simulation | 2007 | English
In order to determine the optimal combination of the heating source equipments in an existing office building, simulations of six different combination cases were conducted using the newly developed mathematical models of each component.
Building use modes are important for energy consumption simulation. But few research concerns building use modes, such as people behavior of opening/closing window, room temperature for airconditioner running, and air-conditioning space and time.
Simulation analysis on the fresh air handling unit with liquid desiccant total heat recovery | 2007 | English
A liquid desiccant fresh air processor is presented whose driven force is low-grade heat (65~70℃ hot water). Inside the processor, the desired cooling source for air’s dehumidification is indoor exhaust air’s evaporative cooling energy.
Performance numerical analysis on an internally-cooled liquid desiccant dehumidifier | 2007 | English
In the internally-cooled liquid desiccant dehumidifier (ICLDD), cooling medium is introduced to carry away the vaporization latent heat, which enhances effectiveness of heat and mass transfer process between liquid desiccant and air.
Occupant evacuation dynamics is a kind of manybody system of strongly interacting persons. A great deal of factors should be taken into account in the study of fire evacuation, such as human behavior, fire products and architecture.
Simulation on hydraulic heating system of building under the control of thermostat radiator valves | 2007 | English
Considering the dynamic control process of thermostatic radiator valves (TRVs) and adjustement behavior of consumers, as well as heat transfer through neighborhood, the main purpose of this paper is to derive a total model for simulating and analy
Personal displacement ventilation (PDV) is a new ventilation concept that intends to combine the positive features of displacement ventilation with those of task conditioning or personalized ventilation. PDV is expected to create a micro-environme
Definition of heating/cooling capacity ratio (HCR) of the heat pump air conditioner has been put forward in this study, and the relationship between supply HCR (HCRS) and demand HCR (HCRD) has been illustrated.
