試験室圧力制御装置
Document Type and Number:
Japanese Patent JP7154712
Kind Code:
B2
Abstract:
To provide a test room pressure control device capable of delivering superior energy saving and environmental performance and curbing a cost.SOLUTION: In a test room pressure control device, a room pressure regulation container 7 is installed inside an environmental test room 2 where a predetermined temperature environment can be created with an air conditioner 3. The room pressure regulation container 7 has an opening section 7a communicated with the interior of the environment test room 2. Pressure inside the room pressure regulation chamber 7 can be regulated with a pressure regulation section 9 capable of regulating an amount of air supplied through a second passage 42 and an amount of air discharged through an exhaust duct 8. A pressure change in the room pressure regulation container 7 is propagated to the interior of the environmental test room 2 through the opening section 7a and the pressure inside the environmental test room 2 and inside the room pressure regulation container 7 is homogenized. Because the air discharged for regulating the pressure is the one inside the room pressure regulation container 7, the test room pressure control device can prevent the air-conditioned air from being uselessly discharged for regulating the pressure. Also, the test room pressure control device hardly requires air used for regulating pressure to be air-conditioned.SELECTED DRAWING: Figure 1
