摘要

To provide a system that can control a space such as a cultivation chamber of plants at a desired state extremely simply and economically.SOLUTION: An air-conditioning system comprises: a switching valve 80 having an intake port 81, a supply port 82, a return port 83 and a discharge port 84; an air circulation channel 10 which connects the supply port and a cultivation chamber 100 for cultivating plants; and a return channel 30 which connects the return port and the cultivation chamber. The switching valve is operable between a first position at which the intake port and the supply port are connected, the return port and the discharge port are connected, and the return port and the supply port are blocked, and a second position at which the return port and the supply port are connected, the intake port and the supply port are blocked, and the return port and the discharge port are blocked.SELECTED DRAWING: Figure 1
