Diseño y construcción de un laboratorio climatizado para equipos de nanotecnología (temperatura y humedad del ambiente).

Abstract

In the Career of Mechanical Engineering of the Higher Polytechnic School of Chimborazo, through the GIDETER research group, he has considered the need to implement a climatized laboratory for nanotechnology equipment such as the carbon nanotube synthesizer by electric arc, microscope, among others, which for their correct operation must be within a controlled environment that meets the requirements of the number of particles temperature and humidity specified in ISO 14644 which refers to the conditions that must be met within clean rooms to obtain accurate results and reliable in each of the investigations that are carried out. The air-conditioned laboratory has been designed and built in the space designated by the authorities of the Faculty of Mechanics and which is located in the Deanship building on the third floor next to the Laboratory of Hydraulic and Pneumatic Systems, which complies with the space requirements and electrical installations. The laboratory volume is 4.95m3 (1.5x1.5x2.2m) which has been selected taking into account the size and quantity of equipment that goes into it. To comply with the parameters of temperature, humidity and number of particles, equipment was selected and purchased for temperature control (21-23 ° C), equipment for humidity control (35-60%), HEPAH14 filters and fans (control number of particles 0.5um) = 3 520 000, 1um = 832,000 particles). The ventilation system must perform 10 air changes in one hour, staying on for two minutes, therefore an automatic control system was also implemented, which ensures the exchange of interior air from the laboratory.
