SYSTEM FOR CONTROLLING ENVIRONMENT OF AIR CONDITIONER-TYPE CLOSED PLANT FACTORY AND CONTROL METHOD THEREOF

摘要

An equipment for controlling an environment of a closed plant factory, according to the present invention, has advantages in that energy can be saved while maintaining an optimal environment for producing plants for pharmaceutical preparation by means of suitable introduction of outdoor air, and a comfortable environment can be provided to workers as well as plants in a daytime mode. In addition, it is possible to save energy by controlling the introduction of outdoor air in consideration of CO₂ concentration in the daytime mode in which the plants carry out photosynthesis, and by cooling using outdoor air in a night mode in which the plants breathe and there are no effects from CO₂. In addition, when indoor CO₂ concentration is within a range between upper and lower limits, since the introduction of outdoor air is controlled by a difference in enthalpy between the indoor air and the outdoor air, outdoor air can be suitably introduced, and the outdoor air can be used for cooling, thereby saving energy.
