The present invention relates to a ventilation and temperature/humidity control system of a mushroom cultivation facility, which uniformly ventilates the whole inner part of the mushroom cultivation facility and can effectively control to maintain proper temperature and humidity. According to the present invention, provided is the ventilation and temperature/humidity control system of a mushroom cultivation facility, which comprises: an air supply pipe (100) having an air supply hole (102), and installed in the longitudinal direction of the mushroom cultivation facility (10) in the middle of the upper side of the mushroom cultivation facility (10) to supply external air blown through an air supply fan (104) to the mushroom cultivation facility (10) multiple exhaust ports (200) formed to be separated on the lower end parts of both sides of the mushroom cultivation facility (10), and equipped with exhaust fans (202) to discharge air in the mushroom cultivation facility (10) outwards and a temperature/humidity control means installed to be symmetrical to each other with respect to the air supply pipe (100) on both longitudinal ends parts of the mushroom cultivation facility (10). The temperature/humidity control means comprises: a fist indoor unit (340) comprising a first air blowing fan (310) and a dehumidifier (320) installed in the rear of the first air blowing fan (310) a second indoor unit (370) composed of a second air blowing fan and installed in front of the first indoor unit (340) and an outdoor unit (390) connected to the first and second indoor units (340, 370).COPYRIGHT KIPO 2016본 발명은 버섯재배사 내부 전체가 고르게 환기되고, 적절한 온도 및 습도를 유지하도록 효과적으로 조절할 수 있는 새로운 구성의 버섯재배사의 환기 및 온도/습도조절시스템에 대한 것이다.본 발명에 따르면, 급기공(102)이 형성되고 버섯재배사(10)의 상측 중앙에서 버섯재배사(10)의 길이방향을 따라 길게 설치되어, 급기팬(104)을 통해 송풍되는 외부공기를 버섯재배사(10)로 공급하는 급기관(100) 상기 버섯재배사(10)의 양측 하단부에 다수개 이격형성되며, 배기팬(202)이 설치되어 버섯재배사(10) 내부의 공기를 외부로 배기시키는 배기구(200) 상기 버섯재배사(10)의 길이방향 양단부에서 상기 급기관(100)을 중심으로 서로 대칭되게 설치되는 온도/습도조절수단을 포함하여 이루
