환기와 증발냉각의 혼합방식을 통한 고발열 기계실 내부의 고온현상 해소방법에 대한 연구

Abstract

The indoor environment of the machine room is obliged to comply with the standards for maintaining the performance of the equipment and creating a safe working environment for workers as well as ensuring the life of the equipment. There are many cases where indoor environment is created through the exclusive use of the outdoor ventilation method of a large amount of heat load in various high-heating machine rooms such as boiler rooms, generator rooms, and steam turbine rooms. Especially, when hot and humid outdoor air is injected into the high-heat machine room during the summer, the inside of the machine room is created into a hot and dry environment and discharged to the outside. In the above dissertation, we compared and analyzed the use of the outboard ventilation method alone and the application of the mixing method of ventilation and evaporation cooling in the elevated heat machine room where the hot and dry environment was created, and confirmed that the improved indoor environment of the medium temperature humid environment can be achieved with reduced air volume by using the mixing method of ventilation and evaporation cooling. Through this, a new ventilation and cooling method was proposed to relieve the high temperature phenomenon inside the high-temperature machine room, and it is estimated that the environmental design will be quantitative to help respond to additional heat generation inside the machine room, respond to peak loads in summer, and adjust the environment mixed with eco-friendly cooling method.
