This paper presents the air temperature analysis and control improvement for the technical zone, where many critical instrumentations of power supply, rf, vacuum and control apparatuses are located, at the Taiwan Light Source (TLS). The technical zone with circular shape is located on the core area of the storage ring. The diameter and height of the technical zone are 28.5m and 3m, respectively. Totally 13 temperature sensors are installed in this zone to online record the air temperature history. Because of insufficient cooling capacity and poor air circulation of the air-conditioning (A/C) system, the air temperature may reach to 30 degrees C, and spatial air temperature difference may be more than 7 degrees C. To cope with those problems, a computational fluid dynamics (CFD) code is applied to simulate the spatial temperature distribution. The A/C cooling capacity will be increased, and the air exit and exhaust distribution will be modified according to the simulated results.

After 13-year operation of the Taiwan Light Source (TLS), National Synchrotron Radiation Research Center (NSRRC), had proposed to construct a new light sourc, Taiwan Photon Source (TPS) in the near future. TPS is preliminarily designed with 3.0 GeV in energy, 518.4m in circumference and 24 Double-Bend Achromat (DBA). This study designed the utility system, including the electrical power system, grounding system, de-ionized cooling water (DIW) system and air conditioning (AC) system for the TPS. Special considerations are focused on the stability of the electrical power and grounding system and temperature control of the DIW and AC systems. The power and cooling loads had been estimated according to each subsystem of the accelerator. Layouts of main utility equipment and piping system had also been preliminarily designed.
