摘要：
This paper firstly presents the operation principle of individually ventilated cages (IVC) system. Measurements on micro-environment of IVC system in laboratory animal room at University of South China are conducted to attain the internal environment parameters (Temperature, humidity, air velocity, air cleanliness and noise). Research results show that internal micro-environment parameters basically meet national standards about the barrier environment, but internal air distribution is uneven. In IVC system, air velocities in the edge side are higher than in the middle side, and the maximum air velocity is about 10% larger than the minimum value. Temperature in internal micro-environment depends on indoor temperatures which IVC system located in, and there has a close correlation between air velocity and temperatures. Internal environment evaluation could provide the first-hand research materials for guiding the breeding and management of laboratory animal.
摘要：
Radionuclides released from uranium mine ventilation shafts would pose radiation exposure to the public and environment. A three-dimensional lagrangian stochastic model has been presented to study the atmospheric dispersion of solid-state radionuclides released from the uranium-bearing mine ventilation shafts. Meteorological conditions and geographical conditions including four downwind velocities (0.5, 1.0, 2.0, 4.0 m/s) and two underlying surface roughness characteristics (0.1 m, 1.0 m) were chose in the study. The radionuclides concentration distributions at various wind speeds and surface roughness were attained to evaluate the pollution in the vicinity of uranium mine ventilation shaft.

摘要：
The ventilation efficiency of different ventilation patterns inside a room containing one person and office furniture arranged by different inlet/outlet configurations was investigated. The numerical simulation (CFD) was first adopted to predict air flow pattern and ventilation performance. Then, a laboratory experimental measurement at room air distribution in a full-scale test chamber was conducted using the hot wire velocimetry (IFA300) to validate the simulation results. In addition, questionnaire surveys were conducted from the different gender groups in order to assess indoor air quality and human comfort in workplace micro-environments. The distribution of supply/exhaust air in the study was investigated in isothermal conditions using different supply air velocities. The results indicated that the ventilation efficiency and human comfort might be dominantly influenced by location of diffuser rather than air change rate.

摘要：
The different ventilation patterns inside a room containing one person and office furniture arranged by different inlet/outlet configurations was investigated. The numerical simulation was first adopted to predict air flow pattern and ventilation performance. Then, a laboratory experimental measurement at room air distribution in a fall-scale test chamber was conducted using the hot wire velocimetry to validate the simulation results. In addition, questionnaire surveys were conducted from the different gender groups in order to assess indoor air quality and human comfort in workplace micro-environments. The distribution of supply/exhaust air in the study was investigated in isothermal conditions using different supply air velocities. The results indicate that the ventilation efficiency and human comfort might be dominantly influenced by location of diffuser rather than air change rate.,
