<p>PROBLEM TO BE SOLVED: To provide a unit capable of controlling mushroom cultivation atmospheres, low in cost, high in energy-saving effect, and capable of accurately and stably controlling temperature and humidity. SOLUTION: This unit is provided with an air-controlling tank 2, having a tank 3 which holds water (W); a temperature-controlling section 4 which controls temperature of W at a given level; a heat-exchanging tube unit which is arranged inside of the tank 3 to exchange heat between air (A) flowing through the tube and water W, and to release air A in the form of bubbles (Ab) from a nozzle section 5S at the front end into water W over the bottom 3d of the tank 3; and a controlled air-sending section 6 which sends out controlled air (As) rising to the surface of water W.</p> |
