PROBLEM TO BE SOLVED: To provide an environmental test device whose power consumption is small and which contributes to energy saving.SOLUTION: An environmental test device 1 has an air-conditioning ventilation passage 15 communicated with a laboratory 5, and air-conditioning equipment 17 and a circulation air blower 10 are provided in the air-conditioning ventilation passage 15. An agitation air blower 20 is provided in the laboratory 5. A real environment detected by a temperature sensor 12 and a humidity sensor 13 and a target environment are compared to each other, and output of the circulation air blower 10 is increased or decreased in accordance with a deviation therebetween. Output of the agitation air blower 20 is changed so as to offset the change in the amount of blowing air of the circulation air blower 10. |
