Abstract: Terletskaya S.S, Stakhiv R.I (supervisor). Development and analysis of climate control system. Master’s thesis. - Lviv Polytechnic National University, Lviv, 2020. Extended annotation. The development of the latest technologies is not possible without modern "clean rooms" designed to perform high-tech production or measurement processes, in particular related to the reproduction of length standards, the accuracy of which is at the level of micrometers and less. "Clean room" is a special room built in such a way as to provide the desired class of cleanliness and the necessary climatic parameters of the environment. Climatic parameters of the environment in such a room are one of the factors of influence, which are regulated by relevant regulations. One of the first tasks of this master’s qualification work is a review of the regulatory framework governing climatic conditions, as well as the solution of problems that arise during the control of climatic parameters. Construction of "clean rooms" (rooms with a high degree of protection against dust and other contaminants), specially designated for research in such areas as carbon materials, nanophotonics, fiber-optic nano-optics (spintronics (spin electronics), nanoconductors (nanowires) and tribology) about friction and wear), associated with many problems. To comply with all the requirements of metrological standards, it is necessary to control the temperature, humidity, vibration, dust and maintain them within specified limits, as well as to insulate the laboratory from external factors [1-3]. Of great importance is also the retention of humidity, within specified limits. The purpose of the master’s qualification work is: • analysis of the regulatory framework governing climatic conditions in "clean rooms"; • analysis of the peculiarities of the structure of "clean rooms", which determine the influence of climatic parameters on the measurement processes and the influence of the measuring instruments themselves on the change of climatic parameters; • synthesis of the structural scheme of the climate control system for a "clean room"; • selection of temperature and humidity measuring instruments that provide the required accuracy; • use of the least squares method to optimize the calibration characteristics of the psychrometer and make recommendations for the placement of temperature sensors to ensure its control; • development of algorithm and means of processing of results of measurements of climatic parameters and formation of control signals of the established mechanisms of system of climate control. The object of research is the process of measuring the temperature and humidity of the environment in the room. Research methods. Theoretical research is based on the use of methods and tools for regulating and measuring temperature and humidity. The practical value of the obtained results lies in the effective operation of the developed climate control system. In the master’s qualification work the system of control of climatic parameters of "clean room" is developed and analyzed. Methods and means of regulation and measurement of temperature and humidity are considered. To control the temperature and humidity of the air, the laboratory is equipped with a new generation of primary transducers, made in the form of IC. The structural and electric scheme of the system is developed, the calculation of the main units of the system is carried out, the errors and metrological support of the climate control system are analyzed. Key words - temperature, humidity, system, climatic parameters. List of sources used. 1.
