Assessment of Thermal Conditions Perceived in Clean High-Tech Laboratories

Popis výsledku v původním jazyce

A thorough design of cleanrooms together with best practices in cleanroom operation enables to minimize the concentration of airborne particles and create the desired environment of high-tech laboratories for precise manufacturing or research. In common practice, the thermal comfort of users is put aside in favour of the achievement of suitable environmental conditions required by installed technologies and ongoing processes. The study assessed thermal conditions experienced in laboratories by both a measurement and a post-occupancy evaluation. Not only the general perception of thermal conditions but also the local discomfort and uniformity of indoor conditions were assessed to examine the possible sources of discomfort. Determination of fundamental problems of indoor conditions can positively affect the user’s well-being and possibly reduce the energy consumption of cleanroom operation. According to the results, the specific environmental conditions of cleanrooms such as high air change rates, temperature levels and the necessity of cleanroom garments resulted in the frequent discomfort of users. The most occurred sources of dissatisfaction were high air velocities and local heat gains perceived as a draught and temperature variations among workplaces respectively. The excessive built-up of the space with technologies and equipment was considered as a significant source of uneven indoor conditions as well as a possible source of increased risk of space contamination. With a view to the better thermal comfort, more than 90 % of users adapt their behaviour. However, some of their actions do not correspond with the cleanroom policy.
