<P>PROBLEM TO BE SOLVED: To provide a calm environment-type plant growing chamber and a temperature adjusting method, capable of accurately controlling plant growing environment, and performing special cultivation for experiment, and efficiently cultivating good plant. <P>SOLUTION: The wind at a supply opening is reduced by mounting a cylindrical cloth filter 20 made of synthetic resin filament yarn on the conditioned air supply opening of an air blower 6 for ventilation. Solenoid valves of a plurality of coolers 3 of an air conditioner 10 are controlled to be ON/OFF by a digital indicator controller 1 to be adjusted to be lower than a set temperature. Then a heater 4 is PID controlled to adjust a temperature in a chamber to the set temperature. The number of times of recirculating ventilation in the chamber is set to chamber internal volume (m3) ×60-150 times/(h), and calm ventilation is performed in the chamber through the cylindrical cloth filter 20. <P>COPYRIGHT: (C)2007,JPO&INPIT |
