National Synchrotron Radiation Research Center, Taiwan, is currently constructing the civil buildings and utility system of the Taiwan Photon Source. The air conditioning (AC) system of the storage ring tunnel was designed based on those of existing Taiwan Light Source and some international advanced accelerators. To predict the air temperature variation and flow pattern in tunnel more precisely, we applied 3D computational fluid dynamics scheme and built up a one-cell mock-up equipped with AC system. In the 3D numerical model, effects of magnets of the booster and the storage ring, girders, cable trays, front ends and the supplied air wind duct are all taken into account. The temperature variations and flow pattern were shown through the numerical simulation. Measured air temperature data in the one-cell mock-up were also collected.

Good Agreement

The personal air conditioning system is used in the battery electric vehicle instead of the traditional one and the experiment validated that this system can make passengers feel comfort after four minutes. All the system can only consume electric power 338.8 W, which is less than the traditional air conditioning of cabin. A simplified 3-D N box vehicle cabin model was created to simulate the thermal distribution under this system by using the CFD analysis and the results of calculation have good agreement with the experiment recording.

Ventilation Scheme

The excellent desk personalized ventilation scheme is found in this paper by the way of comparing the four winter air supply schemes, basing on the numerical simulation software of CFD. We find that air supply quality and air supply angle are both the important factors to personalized ventilation individual comfort in winter. The air temperature and velocity surrounding the human body of the excellent desk personalized ventilation scheme are discussed. It comes to the conclusions that under simulated conditions the excellent desk personalized ventilation scheme can better satisfy the human body comfort on the surrounding air temperature and healthy than the traditional air conditioning, and it is easier to achieve energy saving too.
